Chapter 1: How Your Body Handles Heat

Chapter Introduction

Hi. I am the Camel.

We have met before.

If you read my G3 chapter — Heat and Your Body — you already know that heat is part of the world. You already know your body sweats and your cheeks turn pink in heat. You already know your body wants to slow down on hot days. You already know about drinking water, light clothes, sun hats and sunscreen, shade breaks, and the most important rule of all: kids never wait alone in a parked car in warm weather. You already know that around water in summer, kids are always with trusted grown-ups.

Welcome back. The Camel walks slowly. The Camel is glad to see you again.

You are nine or ten years old now. You are bigger than you were at G3. You have lived through another summer (or warm season, or hot indoor day — wherever you live). You can hold more questions in your head. You are ready for the next step.

The Penguin and I just finished a chapter together. Well — not exactly together. The Penguin wrote How Your Body Handles Cold. I am writing How Your Body Handles Heat. We are climate twins. We teach opposite weather and the same kind of safety. If you read the Penguin's chapter, much of what you learned there has a mirror version here. Cold = make heat + keep heat. Hot = lose heat + limit making more heat. Inverse twins. Same body. Same safety-first care.

This chapter has three big ideas, and each one is one step beyond what we talked about at G3.

The first big idea is how your body actually handles heat. At G3 I told you what your body does when it gets hot. This time I will tell you how it does it. Your body has two jobs in heat — losing heat and limiting how much heat it makes. We will look at each one. And we will look at how your body slowly learns summer over a season.

The second big idea is how to be ready for heat. At G3 I gave you six things that help most kids. This time we will go deeper — why those six things work, plus three more that I have added at G4. The hot-car rule stays. The Camel will say it again because it matters that much.

The third big idea is the most important one, like at G3. When heat is too much. Same danger signals as G3, but with a new G4 understanding — and one new signal you should know about. Plus the rules. Plus what to do if you or someone else gets too hot.

The Camel walks slowly. Are you ready? Keep up.

The Camel Watches Again

The Camel has been watching humans in heat for a long, long time. At G3, I told you that your body sweats when it gets hot. I told you that your cheeks turn pink and your body wants to slow down. I told you that humans are actually quite good at handling heat — better than most large animals.

That is all still true at G4. The Camel is not going to take it back. I am going to ADD to it.

Here is the new G4 idea. Your body has two jobs when it gets hot.

Job One: Lose heat. Your body has to release warmth — get it out of you, into the air or the world around you.

Job Two: Limit making heat. Your body has to slow down its internal heat-making so it doesn't have so much heat to lose.

If your body does both jobs well, you stay cool enough. If one of the jobs starts to fail — if you can't lose heat fast enough, or if you keep generating too much heat — you get hot. If both jobs fail badly, you reach the danger zone we'll talk about in Lesson 3.

This is the inverse of what the Penguin taught at G4 Cold. The Penguin said: cold = make heat + keep heat. The Camel says: hot = lose heat + limit making more. Same body. Two opposite kinds of work depending on what the weather is doing.

Let me show you each job up close.

Heat-Losing Jobs

Your body has several ways to release heat. Some are loud and obvious. Some are quiet and constant.

1. Sweating. This is the loudest one. When your body gets hot, glands in your skin release water — sweat. The sweat sits on your skin. When it dries up — when it evaporates into the air — it carries heat with it. A wet body cooling off as the wet dries is one of the most effective heat-losing tools any animal has. Humans are unusually good at this — humans sweat more from more of their body than almost any other large animal. This is one reason humans can handle heat well [1, 2].

2. Sending blood to the skin. When your body gets hot, it sends extra blood close to the surface of your skin. The skin is where the heat can leave — into the air, into anything cool that touches you, into shade. This is why your cheeks get pink in heat, and why your skin feels warmer to the touch on hot days. The blood is delivering heat to the surface so it can escape [3].

3. Breathing slightly faster. A small amount of heat leaves with each breath out. On really hot days, your breathing speeds up a little — partly to move more air across the moist surfaces inside your nose and throat, where some sweat-like cooling happens. This is a quieter heat-loser but it does add up.

4. Tears, drool, peeing, even moist breath. All the ways water leaves your body — small or large — carry a bit of heat with them. This is one reason why staying hydrated in heat matters so much: every drop of water leaving you takes heat with it, and your body needs to refill the water it's losing.

The Camel thinks of these like a household with one big loud fan (sweating) and three smaller quiet ones (blood-to-skin, breath, water-releasing). When the temperature climbs, your body turns up the big fan. The quieter ones keep running underneath.

Heat-Limiting Jobs

Even with all these heat-losers, your body would still overheat in extreme heat if it kept making heat at full speed. So your body has a second strategy: make less heat.

1. Slowing down. This is the message your body sends in heat — slow down. Move less. Run less. Climb less. This is not laziness. The Lion (Coach Move) taught you at G4 that movement makes heat (muscles working = heat as a side effect). So in heat, the wise body says: less movement = less heat to deal with. When you feel sluggish on hot days, your body is telling you something true.

2. Wanting cool food and cool drinks. Notice this: on hot days, you want a popsicle, not a bowl of soup. You want a cold glass of water, not hot cocoa. Your body is asking for cool input rather than warm input. The Bear (Coach Food) at G4 told you that warm food makes heat through digestion. In summer, that's exactly what you don't want. Cool foods and drinks help your body limit making heat.

3. Seeking shade. When you're outside on a hot sunny day, your body naturally wants to find shade. Shade is cooler than sun — sometimes 15 to 20 degrees cooler, depending on the surface temperature. Standing in sun is the same as having a heat lamp pointed at you. Standing in shade is taking the heat lamp away.

4. Eating less in extreme heat. On really hot days, kids often eat less than usual. This is normal. The body is choosing to digest less to make less heat. Trust the signal. Eat smaller cool meals more often instead of one big hot meal.

The Camel does this naturally. On really hot days in the desert, camels rest in shade or stand very still. They eat less. They drink slowly. They wait. This is millions of years of camel wisdom: in heat, slow is wise.

The Brain Watches Your Temperature

The Penguin taught you at G4 Cold that a small part of your brain watches your body's temperature like a thermostat. In cold, that thermostat says: make more heat, keep more heat. In heat, the same thermostat says: lose more heat, limit how much you make.

The thermostat is the same part. Just opposite signals depending on what's happening outside.

You don't have to think about any of this. Your brain handles it automatically. Bodies are very smart [3, 4].

Your Body Slowly Learns Summer

Here is the parallel idea from G4 Cold, now in heat form.

Your body slowly gets better at handling heat over a summer.

Think about this. The first really hot day of summer — sometime in late May, June, or early July where many kids live — feels brutally hot. By August, that same temperature feels much more manageable. You can play longer. You sweat sooner. You don't get exhausted as fast.

What changed? The temperature didn't. You did. Your body has been practicing summer for weeks by then.

This is acclimatization — same word as G4 Cold, opposite direction. It means your body is slowly adapting to the heat. Over weeks, your body:

• Sweats more efficiently (earlier, more easily, with less salt loss)
• Gets better at sending blood to the skin (the heat-losing move)
• Holds onto more water (you become better at managing your hydration)
• Gets used to the feel of heat so you notice it less [5]

This is real, well-studied biology. Researchers have measured it in athletes, in soldiers training in hot places, in workers who work outside in summer, in kids who play outside through a long summer.

What does this mean for you? The first hot weeks of summer are the hardest. After that, your body adapts. If you live somewhere with a long hot summer, by mid-summer your body is in its summer-form, and heat feels more handleable.

This also means: when you travel somewhere much hotter than home, you'll feel hotter there than the locals do. Your body has not had time to learn that climate. That's not weakness. That's biology — same as for cold.

Every Body Handles Heat a Little Differently

The Camel wants you to know this clearly, as I told you at G3 and as I'll keep telling you: every body is different.

• Some kids feel hot faster. Some kids barely notice heat.
• Bigger bodies sometimes lose heat slower (more mass to keep cool). Smaller bodies sometimes lose heat faster but also struggle in extreme heat. Both are normal.
• Some kids sweat heavily. Some kids barely sweat. Both are normal.
• Some kids have conditions that make heat harder — kids with chronic illnesses, kids with asthma that gets worse in hot humid air, kids on certain medications, kids whose bodies don't sweat as efficiently. The Camel sees every body.
• Kids who use wheelchairs or other mobility supports handle heat their own way — their grown-ups know.
• Kids who have lived in hot climates their whole lives often handle heat better than kids who just moved from a cool place. The body knows what it has been through.

If you have a body that gets hot faster than your friends, you are not weak. If you have a body that barely notices heat, you are not tough. You are just you. The Camel treats all bodies the same — with respect and care.

A Note on Sweating

The Camel wants to say something important here that some kids don't hear often enough.

Sweating is healthy. Sweating is normal. Sweating is one of your body's greatest tools.

Some kids feel embarrassed about sweating — especially in summer, around peers, at the pool, in the gym. Some kids get teased about sweating. Some kids try to hide it.

The Camel wants you to know: sweat is your body doing one of the smartest things it knows how to do. Sweating means your body is working well. A body that didn't sweat in heat would overheat fast. The kids who sweat the most often are the ones with the best heat-handling bodies.

If anyone teases you about sweating, that's about them, not about you. If you feel embarrassed, tell a trusted grown-up. The Camel never lets a kid feel ashamed of one of their body's smartest tools.

Notice Your Heat-Losers and Heat-Limiters

Here is a small thing the Camel wants you to try.

Pick a warm moment — a warm afternoon, a sunny walk, a hot indoor space. Just notice what your body is doing.

• Are you sweating? (Heat-losing.)
• Are your cheeks pink? (Heat-losing — blood to skin.)
• Are you breathing a little faster? (Heat-losing.)
• Are you moving slower than usual? (Heat-limiting.)
• Are you reaching for cold water or cool food? (Heat-limiting.)
• Are you looking for shade? (Heat-limiting.)

You don't have to do anything. Just notice. Once you start, you'll see your body's heat-handling tools at work.

Lesson 1.2: How to Be Ready for Heat

Learning Objectives

By the end of this lesson, you will be able to:

• Explain why light, loose, light-colored clothes help in heat
• Name three foods or drinks that help in heat (and why)
• Tell why shade breaks make such a difference
• Know the hot-car rule by heart
• Name the nine things that help most kids handle heat

Key Terms

A Camel Story

The Camel lives in heat. Real heat. The kind of heat that would exhaust most animals within hours. But the Camel doesn't get exhausted. Camels have several heat-handling tools — thick fur (yes — fur, in the desert! It protects from sun and slows heat coming in), the ability to drink huge amounts of water at once, fat stored in their humps (which their body can use slowly), and the most important thing: they move slowly and rest in shade when the sun is highest.

Camels don't fight the desert. They work with it.

Humans are different from camels. You don't have fur (much). You don't have a hump. But you have something better — clothes, shade, cool drinks, air conditioning, sunscreen, hats, water bottles, and trusted grown-ups. Humans have figured out how to handle heat with tools.

This lesson is about how to use those tools well.

Why Light, Loose, Light-Colored Clothes Help

At G3 I told you to wear light, loose, light-colored clothes in heat. Now I'll tell you why.

Light colors — white, light blue, pale yellow, light gray — reflect sun. Dark colors absorb sun (you can feel this if you touch a black car versus a white car on a sunny day — the black one is much hotter). Light-colored clothes reflect some of the sun's heat away before it reaches your skin.

Loose clothes let air move between the fabric and your skin. The moving air carries away your body's heat. Loose clothes also let sweat evaporate more easily — which is your body's main heat-losing tool. A loose t-shirt is much cooler than a tight one in heat.

Light fabric (thin cotton, linen, or other breathable materials) doesn't trap heat the way thick fabric does. It lets the body's heat escape outward.

Put these three together — light color + loose fit + thin fabric — and you have clothes that help your body do its heat-losing job. This is the opposite of what you wear in cold. In cold (the Penguin taught you), layers trap warm air to keep heat in. In heat, you want the opposite — air flowing freely to let heat out.

Why Sun Protection Matters

The sun is the world's biggest heat source. On a sunny day, the sun is pouring energy onto your skin constantly. Most of this energy turns into warmth — but some of it (a kind of light called UV) can damage your skin if you get too much.

Sunscreen is a cream or spray that blocks most of the UV. It gives your skin a thin shield. You can still feel the warmth of the sun, but the damaging part is mostly blocked [6].

A sun hat with a brim shades your face, neck, ears, and the top of your head — places where sunburn happens most.

Shade is the best sun protection there is. The Rooster (Coach Light) at G3 told you about sun safety too — the Rooster, the Camel, and the trusted grown-ups in your life all agree. Sunscreen + hat + shade is the combo.

(One small note: NEVER look directly at the sun, even with sunglasses. The Rooster taught you this. The Camel agrees. Your eyes are not for looking at the sun.)

Why Shade Breaks Work

The Camel keeps mentioning shade. Here's why.

Shade is much cooler than sun. On a sunny day, the difference can be 15 to 20 degrees. A spot in full sun might feel like 95°F. The same spot in deep shade might feel like 78°F. That's a big difference for your body's heat-losing job.

In shade, your skin is no longer absorbing direct sunlight. Your body can shift from emergency heat-losing to normal heat-handling. You sweat less. Your cheeks fade from bright pink to normal. Your breathing slows. You feel calmer.

This is why shade breaks are one of the Camel's favorite tools in heat. Five or ten minutes in shade lets your body reset before you go back out. Trees, umbrellas, awnings, porches, indoor spaces — any of these work.

The Camel has a rule: in hot weather, never spend hours in direct sun without shade breaks. Even the toughest desert nomads find shade in the middle of the day. So should you.

Why Slowing Down Helps

The Lion (Coach Move) at G4 taught you about pacing — slowing yourself down at the start of a long activity so you don't run out of energy. Pacing matters even more in heat.

When you move hard in heat, your body makes extra heat from your working muscles AND has to lose heat at the same time. This is hard work. In extreme heat, your body can't always keep up.

Slowing down means:

• Walk instead of run on hot days
• Take rest breaks between bursts of play
• Save the hardest activities for cooler parts of the day (morning or evening)
• Stop and sit down when your body says it's had enough

The Camel walks slowly. The Camel rests in shade. The Camel waits for cooler hours to do the harder work. In heat, slow is wise.

Hot Car Safety — The Camel Will Say It Again

The Camel needs to repeat the most important rule in the whole chapter. This rule is so important that the Camel will say it every time we talk.

Kids never wait alone in a parked car in warm weather. Not even for a quick errand. Not ever.

A parked car in sun heats up dangerously fast. Even on a day that doesn't feel that hot — say 70 or 80 degrees — the inside of a parked car can reach over 100 degrees within minutes. A car parked in the sun is like a small hot oven. Cracking a window doesn't help much [7, 8].

Children have been seriously hurt and have died from being left alone in hot cars in the United States, even on days that didn't feel especially hot, even for "just a few minutes." The Camel says this not to scare you, but to make sure you know.

The rules:

• A kid never waits alone in a parked car in warm weather. Even for a few minutes. You go inside with the grown-up, or you wait somewhere cool.
• If you are ever in a parked car by accident — a grown-up has forgotten, or a door is locked from outside — and the car is starting to feel hot, try to get out. If the doors won't open, honk the horn — press it hard, again and again — and yell as loud as you can. Most cars have horns that work even when the car is off. Adults nearby will hear and come help.
• If you see another kid alone in a parked car on a warm day, tell a grown-up right away. Run to the nearest store, knock on a door, yell for help. Grown-ups can call 911 to help that child.

This rule is non-negotiable. The Camel was firm about it at G3. The Camel is firm about it at G4. The Camel will be firm about it at every grade.

Cool Foods and Drinks Help

The Bear (Coach Food) taught you that food becomes you. In heat, the right food and drink can help you stay cool.

Foods that help in heat:

• Water-rich fruits: watermelon, cucumbers, oranges, grapes, strawberries, peaches. These give you water AND food at the same time. The Elephant (Coach Water) at G3 also told you about water-rich foods.
• Cool meals: salads, sandwiches, cold pasta, fruit, yogurt. Less heat from digestion than hot meals.
• Popsicles, ice pops, frozen fruit, frozen yogurt: a cool treat that helps your body cool down.
• Water, water, water: the single most important thing in heat. Drink before you feel thirsty. Drink more on hot days than cool days. Drink more if you're moving or sweating.

What's harder for your body in heat:

• Very hot meals (warm food makes heat-limiting harder)
• Big heavy meals (your body has to digest more, which makes more heat)
• Lots of caffeine or sugary sodas (don't replace water as well as water does)

The Camel is not telling you what to eat. Your family knows your meals. The Camel just wants you to know: in heat, cool input helps your body's heat-limiting job.

A Cool Room for Sleeping

The Cat (Coach Sleep) at G4 taught you that bodies need cool rooms for good sleep. In summer heat, this matters even more.

When your room is too hot at night, your body works harder to stay cool. Your sleep gets lighter. You wake up more. Morning feels worse. Your body never fully rests.

What helps for hot summer nights:

• A fan moving air across you
• Air conditioning if your family has it
• Open windows if outside is cooler than inside
• Lighter sheets and bedding (no heavy comforter)
• A cool damp washcloth on your forehead
• Going to sleep with hair still damp from a cool shower

A well-rested body handles the next hot day better. The Cat and the Camel are partners on this.

The Heat-and-Feelings Connection

The Camel wants to mention something the Turtle (Coach Brain) talked about at G4 in How Your Brain Works.

Heat can affect feelings.

When you're overheated, your brain doesn't work as well. The Turtle taught this — your brain needs cool conditions to think clearly. So in heat, kids often feel:

• More tired or sluggish
• More irritable or grumpy
• Less interested in activities
• Slower at school work or thinking
• Sometimes sadder or more anxious during heat waves

If you ever notice in yourself, or in someone you love, that summer brings low mood or grumpiness or sadness that doesn't lift — that is something to talk about with a trusted grown-up. Most summer feelings come and go. But sustained low mood during summer is worth a conversation. The Turtle and the Camel watch for these patterns the same way the Turtle and the Penguin watch for winter mood patterns. Feelings can come with both heat and cold. Trusted grown-ups handle them.

Nine Things That Help Most Kids in Heat

At G3 I gave you six things. They're all still true. I'm adding three more at G4.

The six from G3:

1. Drink water often. Before you feel thirsty. More on hot days. More if you're moving.
2. Wear light, loose, light-colored clothes. Helps your body lose heat.
3. Sun hat and sunscreen. Sun protection matters.
4. Take shade breaks. Shade is much cooler than sun.
5. Slow down on really hot days. Pacing matters in heat.
6. NEVER wait alone in a parked car in warm weather. The most important rule in the whole chapter.

The three from G4:

1. Cool foods and water-rich fruits help. Cross-ref the Bear and the Elephant.
2. A cool room for sleeping. Cross-ref the Cat.
3. Know your body adapts. The first hot weeks of summer are the hardest. By mid-summer, your body has learned. Be patient with the early days.

None of these are protocols. They're general practices that help most kids. Your family knows what works.

Notice Your Heat-Readiness This Week

Here's what the Camel wants you to try this week, if it's warm or hot where you live.

For one week, notice four things each day:

• Did I drink enough water? Did I feel thirsty often? Did I drink before I felt thirsty?
• Did I find shade when I needed it? Or did I stay in sun too long?
• Did I slow down when my body asked me to?
• Was there a hot-car moment? A walk past a parked car. A reminder to a sibling. A grown-up checking the back seat.

By the end of the week, you'll see patterns. What works. What doesn't. The Camel is glad you're paying attention.

Lesson 1.3: When Heat Is Too Much

Learning Objectives

By the end of this lesson, you will be able to:

• Name seven danger signals of being too hot
• Understand why the Camel says "sweating stops despite being hot" is the most serious sign
• Tell what to do if you or someone else shows danger signals
• Know the cold-water safety rule for summer (same Elephant rule as G3)
• Know what to do in a heat emergency

Key Terms

The Camel Is Going to Be Honest

The Camel is going to be honest with you, like the Camel was at G3 and even more clearly at G4.

Most heat is fine. Most hot weather is just hot weather. With water, light clothes, shade, sun protection, slowing down, hot-car rules, cool food, good sleep, and trusted grown-ups, most kids handle most heat without trouble.

But heat can get too much. When your body's heat-losing and heat-limiting tools start to fail, you are in the danger zone. The Camel wants you to know the signs because knowing matters. A kid who knows the signs can tell a grown-up. A grown-up who knows the signs can save a life.

At G3 I gave you six danger signals. I'm going to give you the same six plus one new G4 signal — the one I think is most important.

The Seven Danger Signals

Remember the two jobs of the body in heat? Heat-losing and heat-limiting. The danger signals happen when one or both jobs start to fail [9, 10].

1. Feeling dizzy, lightheaded, or like you might fall. Your body's heat-losing is struggling. Blood is being pulled toward the skin to lose heat, which can leave less blood for the brain. Sit down right away. Tell a grown-up.

2. Sick to your stomach or a bad headache. Your body's systems are stressed. Heat is wearing on you. Get to shade or indoors. Drink water. Tell a grown-up.

3. Very tired or weak in heat. This isn't normal tired — this is a body running out of capacity to handle the heat. Stop, rest in shade, drink water, tell a grown-up.

4. Skin is hot and dry OR very sweaty and you feel sick. Both can be danger signs. Sweat-stopped skin is a serious sign (see #5). Sweaty-plus-sick is heat exhaustion.

5. SWEATING STOPS even though you're still hot. This one is new at G4 and important. If sweating is your body's biggest heat-losing tool, what does it mean when the sweating stops while the heat continues? It means your body has run out of water or energy to sweat. This is the inverse of what the Penguin taught at G4 Cold about "shivering stops despite cold." Both signal a body system running out of power. Tell a trusted grown-up RIGHT AWAY. This is heatstroke beginning. A grown-up may call 911. [10]

6. Confused or talking funny. When your body overheats, your brain doesn't work right. Confused thinking, slurred speech, or saying strange things in heat is a serious sign. Tell a grown-up right away. Grown-up may call 911.

7. Sudden muscle cramps. Painful tightening in legs, arms, or belly during or after activity in heat. Often a sign of heat strain. Stop, rest in shade, sip water slowly, tell a grown-up.

The Camel wants you to remember the conceptual frame: your body has tools for heat, but the tools run out of power if you're in heat too long, too hot, dehydrated, or in direct sun without protection. When you see the danger signs, the tools are running out. Time to cool down and get help.

The serious ones — sweating stops, confusion, can't stand up — are emergency signals. A trusted grown-up will call 911.

Heatstroke and Heat Exhaustion

You learned these words at G3. They still mean the same things at G4.

Heat exhaustion is when your body is overworked from heat but still trying to handle it. Signs: heavy sweating, weakness, dizziness, headache, sometimes nausea. What to do: get to shade or indoors, take off extra clothes, drink water slowly, put a cool wet cloth on the back of the neck and forehead, rest. Tell a grown-up. Usually recovers within an hour with cool down and water [10].

Heatstroke is more serious. The body has stopped being able to handle the heat. Signs: very hot skin, often no sweating, confusion or trouble thinking, fast pulse, sometimes fainting. What to do: this is an emergency. Tell a grown-up immediately. The grown-up will call 911 and start cooling the person down — wet cloths, ice packs on neck and underarms, getting them out of heat. [11]

The Camel wants you to know these words because if a grown-up or a doctor uses them, you'll understand what they mean. You don't have to diagnose anyone — that's a grown-up's job. You just have to recognize the danger signals and tell a grown-up. That's enough.

Hot Car Safety — One More Time

The Camel said the hot-car rule in Lesson 2. The Camel is going to say it once more in this lesson because hot cars are the single most preventable heat danger for kids.

Kids never wait alone in a parked car in warm weather. Ever. Not for any reason. Not for any amount of time.

If you ever find yourself locked in a hot car, honk the horn and yell. If you see another kid alone in a parked car on a warm day, tell a grown-up immediately. Grown-ups call 911 if needed.

This rule has saved lives. The Camel will keep saying it as long as kids need to hear it.

Summer Water Safety

The Elephant (Coach Water) at G3 taught you the cold-water rule: kids never go in water alone. That rule applies to all summer water too — pools, lakes, beaches, rivers, hot tubs, even kiddie pools and bathtubs for younger siblings.

Summer water rules:

• Kids never go in water alone. Always with a trusted grown-up watching.
• The watching grown-up must be paying attention — not on a phone, not far away.
• Only swim in safe places (pools with lifeguards, beaches with lifeguards, places trusted grown-ups have approved).
• Wear life jackets around open water (boats, docks).
• Even strong swimmers follow the rule.

Summer water is wonderful AND deserves great respect. The Elephant and the Camel agree completely.

About Sunburn

The Rooster (Coach Light) at G3 told you that the sun can burn your skin if you get too much. Sunburn is a real heat-related injury.

Sunburn signs: red skin that feels hot to the touch, sometimes painful, sometimes peeling later. Bad sunburns can blister and require a doctor.

Prevention:

• Sunscreen (your trusted grown-up applies it for you on hard-to-reach places like your back and shoulders)
• Sun hat
• Light clothing covering more skin
• Shade
• Avoiding the strongest sun (10 a.m. to 4 p.m. is the highest UV time)
• Drinking water (helps your skin cope)

If you get a sunburn, tell a grown-up. They can help cool the burn with cool water, apply gentle lotion, and decide if you need to see a doctor [6, 12].

Fevers — Different From Outside Heat

The Camel mentioned this at G3 briefly. Here's a slightly fuller G4 version.

A fever is heat from inside your body, not from outside. It usually means your body is fighting off germs. The thermostat in your brain has temporarily moved its target higher — to help your immune system fight infection.

Signs of fever: feeling hot, sometimes chills (yes — feeling cold even while hot), tiredness, sometimes muscle aches, sometimes headache.

What to do: Tell a grown-up. They may use a thermometer to check, may give you medicine if your doctor has said it's okay, may give you fluids, may have you rest. If a fever is very high, lasts a long time, or comes with confusion or stiff neck, the grown-up may take you to a doctor or call 911 [13].

Fevers and outside heat are different problems. A kid with a fever in a hot room is having TWO heat problems — fight off germs internally AND cope with hot room externally. Cool the room down for the kid; the body will handle the fever with help from the grown-up and possibly medicine.

Heat-And-Feelings Continued

In Lesson 2 I mentioned that heat can affect feelings. Here in Lesson 3, the Camel wants to say this more clearly because it matters.

If you notice in yourself, or in someone you love, that summer brings sustained sadness, agitation, or anxiety that doesn't lift — tell a trusted grown-up.

Patterns to watch for:

• Feeling slow, sluggish, or sad most of the summer
• Sleep getting worse for many weeks of summer
• Eating much less than usual for many weeks
• Feeling more anxious or worried during heat waves
• Losing interest in summer activities you used to love
• Body-image worries surfacing in summer clothing (swimsuit anxiety, sweat embarrassment)
• A friend or sibling showing any of these patterns

These are the same kinds of patterns the Turtle (Coach Brain) at G4 named in Lesson 3 of How Your Brain Works. Sustained low mood during summer, just like during winter, is worth a conversation with a trusted grown-up.

The Camel is firm but kind: these are not diagnoses. They are patterns worth a conversation with your trusted grown-up, your doctor if your grown-up thinks that's right, or a school counselor.

When a Feeling Feels Really Scary or Unsafe

The Camel is going to be careful here, like every other Coach.

Sometimes a feeling can get really big. Maybe sustained summer sadness. Maybe heat-and-body-image worries that won't lift. Maybe a feeling makes you want to hurt yourself. Maybe a feeling makes you not want to be here.

If a feeling like that ever comes up — tell a trusted grown-up right away. Not later. Right then. Even if it is the middle of the night. They will not be mad. They will be glad you told them.

If you cannot reach a trusted grown-up at that moment, here are the helpers grown-ups can use. You don't have to remember the numbers.

• For a heat emergency or any medical emergency: a grown-up can call 911.
• 988 Suicide and Crisis Lifeline: a grown-up can call or text 988, day or night.
• Crisis Text Line: a grown-up can text HOME to 741741, day or night.
• SAMHSA National Helpline: 1-800-662-4357, day or night.
• National Alliance for Eating Disorders: 866-662-1235, weekdays. The Bear at G4 told you about this one. (Especially relevant if heat brings up body-image worries, like worry about how you look in summer clothes.)

These are for grown-ups to use. Kids your age don't call helplines on their own. You tell a trusted grown-up first. The grown-up takes care of the rest.

The Bear, the Turtle, the Cat, the Lion, the Penguin, and the Camel are all saying the same thing. You are not alone with heat worries or feelings. Not now, not ever.

Heat Is Part of Life

The Camel will end this chapter the same way the Penguin ended G4 Cold, because the message is the same just in the opposite direction.

Heat is part of life. Your body is good at handling it. You are not alone.

At G4 I will add: you know more about heat now than most grown-ups do. You know about heat-losing and heat-limiting. You know about acclimatization. You know about hot-car safety. You know about pacing in heat. You know the seven danger signals — including the new one (sweating stops despite being hot). You know when to tell a grown-up.

That is real knowledge. The Camel will see you again at Grade 5. There is more to learn then. For now, this is enough.

The Camel walks slowly. The Camel walks slowly because the Camel does not need to walk fast.

Keep up. The Camel is glad you came back.

End-of-Chapter Activity: A Hot-Day Plan

The Camel has one activity for you. It takes one warm or hot day with a trusted grown-up's help.

What You Need

• A piece of paper or notebook
• A pencil
• One warm or hot day
• A trusted grown-up to talk with at the end

What You Do

Step 1 — Plan your day. Before the day, sit with a trusted grown-up and plan how you'll handle the heat. Make notes on:

• What I'll wear (light, loose, light-colored, hat?)
• What I'll drink (water bottle, how often)
• Where my shade breaks will be (which trees, which buildings, which inside spots)
• What I'll eat (water-rich foods? cool meals?)
• When I'll slow down (middle of the day? particularly hot afternoon?)
• The hot-car rule (I will never wait alone in a parked car — I remember this)

Step 2 — Track during the day. Carry your paper. Note when you:

• Drank water
• Found shade
• Felt your body heating up (sweating, pink cheeks, thirsty)
• Slowed down or took a break
• Used your hot-car safety knowledge (walking past parked cars, helping a sibling, etc.)

Step 3 — Check for danger signs. At the end of the day, ask yourself: did I feel any of the seven danger signals at any point? If yes, did I tell a grown-up?

Step 4 — Share with a trusted grown-up. Show your plan and tracking to a grown-up. Ask them:

• What was the hardest moment of the day in heat?
• What worked best?
• What would we change next time?

Step 5 — Keep the page. Save it. The Camel thinks these are useful to look back on — kids who do this a few times build real summer wisdom.

What You Will Get From This

You will see your own heat-handling tools in action — how you used water, shade, light clothing, pacing, hot-car rules. You will share something practical with a trusted grown-up. And you will start to build the body-knowledge that the Camel has spent thousands of years developing.

That is a small habit. It is also a real skill. The Camel thinks both are true.

1. Name the two jobs your body has in heat.

2. Why do light, loose, light-colored clothes help in heat?

3. What is the hot-car rule?

4. Name three of the seven danger signals.

5. Why does the Camel say "sweating stops despite being hot" is the most serious sign?

6. If a feeling about heat or summer gets really big or sticks around, what should you do?

Instructor's Guide

This guide is for parents, caregivers, teachers, and other grown-ups using this chapter with a child in Grade 4 (ages 9-10).

What This Chapter Teaches

This chapter is the second chapter in Coach Hot (the Camel)'s K-12 spiral and the sixth chapter of the Grade 4 cycle. It is the climate twin to the just-shipped G4 Cold chapter (the Penguin) — the Camel and Penguin teach inverse safety with parallel structure. The chapter teaches three big ideas at age-appropriate Grade 4 depth:

1. How your body handles heat. Builds on G3's sweating/heat-to-skin/slowing-down by adding the two-jobs frame: the body has heat-losing jobs (sweating, blood-to-skin, breath, water releasing) and heat-limiting jobs (slowing down, wanting cool food and drink, seeking shade, eating less in extreme heat). This mirrors G4 Cold's heat-making/heat-keeping frame, locking the inverse-twin structure across the two environmental coaches. The brain's role as thermostat is reinforced (cross-ref G4 Cold and G4 Brain). Heat acclimatization is introduced as G4 vocabulary — same word used in G4 Cold for cold adaptation, here applied to heat (the body slowly learns summer parallel to learning winter). The chapter is body-positive about sweating — naming sweat as a sign of a smart, well-functioning body and addressing the social embarrassment some kids feel about sweating.

2. How to be ready for heat. Builds on G3's six (water, light/loose clothes, sun hat/sunscreen, shade breaks, slowing down, hot-car safety) with three G4 additions (cool foods, cool sleeping room, knowing the body adapts). The chapter teaches the why behind each: why light/loose/light-colored clothes work (reflect sun, allow air movement and sweat evaporation), why sun protection matters (UV-without-technical-naming at G4), why shade breaks work (15-20 degree difference), why slowing down helps, why hot cars are deadly. The hot-car rule is reinforced as the most consequential safety rule in the chapter. Briefly introduces the heat-and-mood connection — cross-references G4 Brain Lesson 3 patterns; heat can bring sustained low mood in some kids parallel to winter cold.

3. When heat is too much. This is the safety-critical lesson. Carries forward G3's six danger signals and adds a seventh — the SWEATING-STOPS-DESPITE-HEAT signal as a serious indicator of failing heat-losing. This is the direct parallel to G4 Cold's new SHIVERING-STOPS-DESPITE-COLD signal — both are heat-related body systems running out of power. Heatstroke and heat exhaustion are reinforced as vocabulary with clear what-to-do guidance. The hot-car rule is reinforced one more time. Summer water safety carries forward (kids never in water alone — the Elephant rule). Sunburn and fever distinctions carry forward from G3. 911 framing carries forward from G3 Move's introduction.

What This Chapter Does NOT Teach

This chapter is intentionally light on content that becomes appropriate at later grades:

• No thermoregulation technical vocabulary (vasodilation, evaporative cooling physics, hypothalamus). Grade 6 territory.
• No temperature math (Fahrenheit/Celsius, heat index calculations, dew point). Grade 6.
• No sauna / heat-exposure protocols at any level. K-12 firewall total, same as the cold-plunge firewall in G4 Cold. No "heat therapy" or "heat conditioning" framing.
• No prescriptive temperature thresholds ("above X degrees, do Y"). General practices only.
• No body-shape framing as negative. Sweating is explicitly normalized as healthy. Body-image concerns at ages 9-10 (summer swimsuit anxiety, sweat embarrassment from peers) are addressed protectively.
• No clinical heatstroke management detail. Recognition and tell-a-grown-up only.
• No Hof method or any branded heat protocol. K-12 influence-free zone total.

If your child asks questions in these areas, the best answer is: "That is a great question. Let's figure it out together." Then you, the trusted grown-up, decide what to share.

How to Support the Child

• Build summer routines together — water bottle, sunscreen, hat, shade plans. Children at ages 9-10 are increasingly capable of self-managing these tools when adults model and equip.
• Take the hot-car rule seriously. Reinforce it every summer. Even on days that don't feel hot. The single most preventable child heat death is hot-car-related.
• Watch for heat acclimatization patterns. Early summer is hardest. If your child seems extra tired or struggling in late May/early June, that's biology. By August they'll cope better.
• Address sweat embarrassment if it surfaces. Children at ages 9-10 sometimes get teased about sweating, especially in PE class or at the pool. The chapter normalizes sweat as healthy; reinforce that at home.
• Watch for sustained summer mood changes. Most kids' summer moods come and go. But sustained low mood, agitation, or withdrawal during heat waves can be a real pattern worth a pediatrician conversation. (Sometimes related to heat physiology, sometimes to other underlying conditions surfacing.)
• Be the safe adult for heat-and-body-image worries. Summer brings more body exposure (swimsuits, shorts, sleeveless shirts). If your child shows anxiety about how they look in summer clothes, take it seriously. The chapter routes these worries to trusted grown-ups; you are that grown-up.

Watching for Warning Signs

If you notice any of the following, please contact your pediatrician or a qualified clinician:

• Acute heat injury signs (the seven in Lesson 3, especially SWEATING STOPS while still hot, confusion, can't stand up). These are 911 situations.
• Sustained summer low mood or agitation (more than two to three weeks of persistent sadness, withdrawal, sleep changes, lost interest during summer or heat waves). Seasonal patterns can go both ways.
• Compulsive interest in heat exposure (sauna-seeking, "sweating to lose weight," heat-related body practices tied to social media). The chapter does not introduce or normalize these.
• Body-image distress around summer clothing. Anxiety about swimsuits, shorts, sleeveless tops can signal emerging body-image concerns at ages 9-10.
• Any mention of not wanting to be here, wanting to hurt themselves, or feeling hopeless — these require immediate response.

Verified resources (May 2026):

• 911: for any acute heat emergency, including heatstroke, heat exhaustion not improving with cool down, hot-car incidents, or summer water emergencies.
• 988 Suicide and Crisis Lifeline: call or text 988, 24/7.
• Crisis Text Line: text HOME to 741741, 24/7.
• SAMHSA National Helpline: 1-800-662-4357, 24/7.
• National Alliance for Eating Disorders: 866-662-1235, weekdays. Particularly relevant when heat practices appear alongside body-image concerns.
• Your pediatrician is the best starting place for any persistent concern that is not an acute emergency.

Note: the NEDA helpline (1-800-931-2237) is not functional as of this writing. Use the National Alliance for Eating Disorders number above instead.

Pacing

If you are using this chapter in a classroom:

If you are using this chapter at home, two lessons per week is comfortable. The hot-car rule is worth reinforcing aloud every summer. Lesson 3 may benefit from being read with a trusted grown-up — both because the danger-signal content matters and because the hot-car rule deserves family-conversation reinforcement.

Lesson Check Answers

Lesson 1.1:

1. Heat-losing and heat-limiting. 2. Any two of: sweating, sending blood to the skin, breathing slightly faster, tears/drool/peeing/moist breath. 3. Any two of: slowing down, wanting cool food/drinks, seeking shade, eating less in extreme heat. 4. Yes. Sweating is healthy — it's one of the body's smartest cooling tools, and kids who sweat are not "weak" — they are well-equipped for heat. 5. Heat acclimatization is when the body slowly gets better at handling heat over weeks. August feels less hot than June because the body has had time to adapt — sweating more efficiently, sending blood to skin better, getting used to the feel of heat.

Lesson 1.2:

1. Light colors reflect sun (instead of absorbing it). Loose clothes let air move freely and let sweat evaporate. Light fabric doesn't trap heat. Together they help the body's heat-losing job. 2. Sometimes 15 to 20 degrees cooler in shade than in direct sun. 3. Kids never wait alone in a parked car in warm weather. Not for any time. Not for any reason. 4. Any answer from the lesson: water-rich fruits (watermelon, cucumbers, oranges, grapes), cool meals (salads, sandwiches), popsicles/frozen treats, plenty of water. They help because they don't add heat from digestion and they replace water lost through sweating. 5. Any three of: drink water often, light/loose/light-colored clothes, sun hat and sunscreen, shade breaks, slow down on hot days, hot-car rule, cool foods, cool sleeping room, knowing the body adapts.

Lesson 1.3:

1. Any three of: dizziness/feeling like falling, sick stomach/headache, very tired/weak in heat, hot dry skin OR very sweaty + sick, SWEATING STOPS while still hot, confusion or talking funny, sudden muscle cramps. 2. Because sweating is the body's biggest heat-losing tool. When sweating stops while the body is still hot, the body has run out of water or energy to sweat — heat-losing has failed. This is heatstroke beginning. Tell a grown-up RIGHT AWAY — a grown-up may call 911. 3. Kids never wait alone in a parked car in warm weather. 4. Heat exhaustion: heavy sweating, weakness, dizziness, headache, sometimes nausea. Cool down + drink water + tell a grown-up; usually recovers in an hour. Heatstroke: very hot skin, often NO sweating, confusion, fast pulse, sometimes fainting. Emergency — grown-up calls 911. 5. Tell a trusted grown-up right away. The grown-up can call 988 or another resource if needed.

Chapter Review Answers

1. Heat-losing and heat-limiting. 2. Light colors reflect sun. Loose clothes allow air movement and sweat evaporation. Together they help the body's heat-losing job. 3. Kids never wait alone in a parked car in warm weather. 4. Any three of the seven from Lesson 3. 5. Because sweating is the body's main heat-losing tool. When sweating stops while still hot, the body has run out of water or energy — heatstroke is beginning. 6. Tell a trusted grown-up right away.

Discussion Prompts

1. What is one heat memory you have? Were any of the heat-losers or heat-limiters happening?
2. Have you noticed your body "learning summer" over a season? What was it like at the start vs the middle?
3. What is your favorite cool food or drink in heat?
4. The Camel says sweating is healthy and a sign of a smart body. Does that change how you think about sweating?
5. The hot-car rule is one the Camel says over and over. Why does it matter so much?
6. Some kids feel sadder or more agitated in summer heat waves. Do you ever feel this? What helps?
7. The Penguin and the Camel are climate twins. What is one thing they both teach?
8. Who is a trusted grown-up you would tell first if you saw a danger sign of being too hot?

Common Child Questions

• "Why do I sweat so much?" Sweating is your body's main way of cooling itself. Heavy sweaters often have excellent cooling systems. Some kids sweat more than others — it's biology, not weakness.
• "Why do my cheeks turn red when I'm hot?" Your body sends blood to your skin to release heat. The redness is the heat-losing move at work.
• "Can I die from a hot car?" Yes — kids have been seriously hurt and have died from being left alone in hot cars. That's why the rule is absolute. You never wait alone in a parked car. Never.
• "What if I see a friend who looks really hot and tired?" Tell a trusted grown-up right away. If they're showing serious signs (confusion, no sweating, can't stand up), the grown-up may need to call 911.
• "Why does heat make me grumpy?" Heat makes your brain work harder to cool itself. Overheated brains aren't at their best. You're not in a bad mood for no reason — heat is real.
• "My friend says they don't sweat. Is that good?" Maybe. Some kids sweat very little, which is usually fine in moderate weather. But it can be a problem in extreme heat because sweating is the main cooling tool. If a friend doesn't sweat at all and is overheating, that's a danger sign — tell a grown-up.
• "What if a heat wave makes me feel really sad?" Tell a trusted grown-up. Some kids feel sustained low mood in summer just like some kids feel sustained low mood in winter. The Turtle and the Camel both watch for these patterns.
• "Can I go in a sauna?" That's a conversation for your trusted grown-ups and your doctor. The Camel at G4 teaches everyday heat safety, not heat-exposure practices. Some grown-up heat practices are not for kids your age and should not be tried without grown-up support and a doctor's input.
• "How do I know if I'm dehydrated?" Signs: feeling very thirsty (often you're already a little dehydrated when you feel thirsty), dark yellow pee, headache, feeling tired, dry mouth. Drink water. Tell a grown-up if it doesn't improve.

Parent Communication Template

Dear families,

Your child is beginning Chapter 1 of the Grade 4 CryoCove Library Coach Hot curriculum — How Your Body Handles Heat. This is the second chapter in Coach Hot (the Camel)'s K-12 spiral, building on the Grade 3 chapter Heat and Your Body. It is the climate twin to the just-shipped Grade 4 Cold chapter (How Your Body Handles Cold) — same safety-first structure, inverse direction.

What the chapter covers:

• How the body actually handles heat — through two jobs (heat-losing and heat-limiting), with body-positive framing of sweating as a healthy and smart cooling tool
• How the body slowly adapts to heat over a summer (heat acclimatization, parallel to cold acclimatization at G4 Cold)
• Why light/loose/light-colored clothes work (reflect sun, allow air movement and sweat evaporation), why sun protection matters, why shade breaks make a 15-20 degree difference, why slowing down helps
• The hot-car rule reinforced as the most consequential safety rule in the chapter
• The heat-and-mood connection — some kids feel sustained low mood in heat waves, parallel to winter mood patterns
• Seven danger signals (carrying forward six from G3 plus a new seventh — when SWEATING STOPS despite still being hot, indicating heatstroke beginning)
• The hot-car rule, summer water safety, sunburn, and fever distinction
• The 911 framing carries forward from Grade 3

Tone: The chapter is calm, patient, hardy, and consistently safety-aware. The Camel opens with "Hi. I am the Camel. We have met before." and the desert-wisdom "Camel walks slowly" signature is preserved. The Camel acknowledges the Penguin as climate twin explicitly throughout. The Camel never compares one child's heat tolerance to another's and never frames sweating as embarrassing.

What this chapter does not teach: thermoregulation technical vocabulary (vasodilation, evaporation physics — Grade 6 territory), temperature math (heat index, Fahrenheit/Celsius — Grade 6), sauna or heat-exposure protocols at any level (the K-12 firewall is total, parallel to the cold-plunge firewall at G4 Cold), prescriptive temperature thresholds, body-shape framing as negative, or clinical heatstroke management beyond recognition and grown-up notification.

End-of-chapter activity: Your child will spend one warm or hot day on a hot-day plan — what they wear, what they drink, where they take shade breaks, the hot-car rule reinforcement — and share with a trusted grown-up at the end. Please support this activity.

A note on Lesson 3: Lesson 3 covers when heat is too much and includes the hot-car rule reinforced (the most consequential preventable heat danger for kids), the seven danger signals with the new G4 SWEATING-STOPS signal (parallel to G4 Cold's SHIVERING-STOPS signal — both indicate failing thermoregulation), heatstroke and heat exhaustion vocabulary, summer water safety carryforward, sunburn and fever distinctions, and the heat-and-mood connection. The hot-car rule is non-negotiable — kids never wait alone in a parked car in warm weather, even briefly, even on days that don't feel that hot. Crisis resources (911, 988, Crisis Text Line, SAMHSA, National Alliance for Eating Disorders) are introduced at age-appropriate "grown-ups can call these" framing.

Warning signs we ask families to notice: acute heat-injury signs (especially sweating stopping while still hot), sustained summer low mood beyond two to three weeks, compulsive interest in heat-exposure practices (sauna seeking, "sweating to change body" framing), body-image distress around summer clothing, or any mention of not wanting to be here. The chapter does not introduce or normalize any heat-exposure practice.

If you have any questions, please reach out to your child's teacher or to us at the CryoCove team.

Warmly, The CryoCove Curriculum Team

Illustration Briefs

Lesson 1.1 — Two Jobs of the Body in Heat Placement: After "The Camel Watches Again." Scene: A simple side-by-side illustration showing the two jobs of the body in heat. Left panel labeled "Heat-losing jobs" shows a child outside on a sunny day, slightly sweaty, with arrows pointing to: sweat on forehead (with a small "evaporating" cloud above), pink cheeks (with arrows showing heat moving from inside outward), and a small breath cloud. Right panel labeled "Heat-limiting jobs" shows the same child now resting in a shaded spot, sitting calmly with a cool drink, holding a piece of watermelon. Arrows point to: stillness, the shade overhead, and the cool drink and watermelon. Coach Hot (the Camel) stands between the two panels, one front leg gestured toward each, looking patient and pleased. Mood: clear, warm, never panicked. Show diverse skin tones and body types throughout the chapter — including kids of different body sizes, kids using mobility supports, kids from different climates (hot dry desert, hot humid coastal, mild summer suburban). Aspect ratio: 16:9 web, 4:3 print.

Lesson 1.2 — Hot-Day Tools Placement: After "Nine Things That Help Most Kids in Heat." Scene: A simple illustration showing a smiling child with nine small labeled icons or items arrayed around them: 1) a water bottle, 2) a light-colored loose t-shirt, 3) a sun hat, 4) a tube of sunscreen, 5) a tree (shade), 6) a couch or chair (slowing down), 7) a parked car with a clear NO symbol (hot-car rule), 8) a watermelon slice (cool food), 9) a fan blowing toward a bed (cool room). Coach Hot (the Camel) stands beside the child looking pleased. Mood: practical, warm, accessible. Show diverse skin tones. Aspect ratio: 16:9 web, 4:3 print.

Lesson 1.3 — Seven Danger Signals Placement: After "The Seven Danger Signals." Scene: A simple educational illustration showing the seven danger signals in a calm, non-scary way. Seven small panels arranged in a 2x4 grid (one cell for Coach Hot). Panel 1: child sitting down looking dizzy. Panel 2: child holding their head/stomach. Panel 3: child slumped against a wall looking very tired. Panel 4: child looking hot, with sweat visible. Panel 5: same child but now with dry skin and a worried trusted grown-up beside them (caption: "sweating stops but still hot — SERIOUS"). Panel 6: child looking confused, with a concerned grown-up. Panel 7: child holding leg with a small "ouch" symbol (muscle cramp). Coach Hot (the Camel) in the eighth cell with one foreleg raised in a "tell a grown-up" gesture. Above the grid: "Signs that heat is too much. Tell a trusted grown-up right away." Mood: serious but not scary. Show diverse skin tones and body types. Aspect ratio: 16:9 web, 4:3 print.

Optional — Lesson 1.2: Hot Car Safety Placement: After "Hot Car Safety — The Camel Will Say It Again." Scene: A simple illustrative scene showing the hot-car rule visually. Foreground: a child holding hands with a trusted grown-up, walking away from a parked car in a parking lot (the grown-up has clearly checked the back seat — backpack visible being carried, car keys in hand). The car has a small "empty" indicator inside — clearly no one left inside. Background: a clear no-kid-alone-in-car symbol on the parked car. Coach Hot (the Camel) stands to one side with a small caption: "Kids never wait alone in a parked car in warm weather. Never." Mood: clear, instructive, not scary. Show diverse skin tones. Aspect ratio: 16:9 web, 4:3 print.
