Hi there! Have you ever seen a dog panting when it’s hot outside or after running around? You might have heard that dogs pant because they can’t sweat. Well, that’s partly true! Dogs can sweat, but only on their paws.
Someone named Aditya asked a great question: Why do we sweat when we play sports? You might have heard that sweating helps cool us down, but does it really? When you’re playing and get all sweaty, do you actually feel cooler? Sometimes it just feels sticky and uncomfortable, and it can even make you smell bad. So, why do our bodies sweat?
Let’s find out! Sweating is important because it helps cool us down. But don’t just take my word for it. Let’s see what happens if someone can’t sweat. There are people who naturally can’t sweat. At first, that might sound nice, but it’s actually a big problem. One man who can’t sweat said, “I can’t cool down when I get hot. It feels like I’m cooking from the inside out.” Yikes!
Our bodies need to stay at a certain temperature. If we get too hot, we can feel sick, get muscle cramps, or even faint. Normally, when we get too hot, our bodies send signals to our skin to release sweat, which cools us down. But for someone who can’t sweat, like that man, it can be dangerous to exercise or be outside on a hot day.
There’s a dad whose son can’t sweat. When his son gets too warm, he feels tingling in his limbs. To stay cool, he uses water misters and ice, and sometimes he has to jump in a pool or pour water on himself.
For those of us who can sweat, it’s like having a natural air conditioner! Sweat is mostly water, and even though it can be uncomfortable, it’s really important. It’s how our bodies keep the right temperature. People who can’t sweat have to find other ways to cool down, or they might overheat.
That’s all for this week’s question. Thanks, Aditya, for asking it! For the next episode, I found three questions you can vote on: How does a song get stuck in your head? Do monkeys eat anything besides bananas? Or how do scientists figure out so many answers?
Make sure to vote when the video is over. I want to hear from all of you watching. There are mysteries all around us. Stay curious, and see you next time!
Experiment with Sweat: Try a simple experiment to understand how sweating cools us down. On a warm day, take two small towels. Wet one towel with water and leave the other dry. Place both towels on your arms and sit in a sunny spot. After a few minutes, notice which arm feels cooler. Discuss why the wet towel might feel cooler and how this relates to sweating.
Design Your Own Cooling System: Imagine you are an inventor tasked with creating a cooling system for someone who can’t sweat. Using materials like paper, straws, and tape, design a simple model of a cooling device. Think about how you can use water, air, or ice to help cool someone down. Share your design with the class and explain how it works.
Observe and Report: Over the next few days, pay attention to when and why you sweat. Keep a simple journal to note down activities that make you sweat and how your body feels afterward. Discuss with your family or friends how sweating helps you stay cool and why it’s important for your health.
Sure! Here’s a sanitized version of the transcript:

Hi, it’s Doug! Have you ever seen a dog pant like this when it’s hot outside or when they’ve been running around? You might have heard that dogs pant like this because they can’t sweat. I did some research and found out that that’s partly true. Dogs can sweat, but only on their paws.
Someone named Aditya has a question about sweating. Let’s give him a call now.
Hi, Doug! Hi, Aditya! I have a question for you: Why do we sweat when we play sports? That’s a great question! You might have heard before that sweating helps cool you off, but does it really? When you’re running around and playing sports and you get sweaty, do you really cool down? Sometimes it seems like all sweating does is make you feel sticky and uncomfortable. Plus, sweating can lead to body odor. If sweating is so uncomfortable, why do our bodies do it? What do you think?
Now would be a good time to pause the video and discuss.
Okay, you ready? People say that sweating is good because it cools us down, but we don’t have to take their word for it. We can figure out whether sweating really works by seeing what happens if people don’t sweat. There are some people who naturally don’t sweat; their bodies actually can’t sweat. Now, that might sound great, but listen to this man who can’t sweat describe what his life is like: “I cannot cool down when I get hot. My sweat glands are not being activated. My temperature doesn’t go up, I don’t get a fever, but my body core is just raging hot. It’s painful; it feels like I’m cooking from the inside out.”
That’s a serious problem. Our bodies need to maintain a certain temperature. If it gets too hot or overheats, you can start feeling sick, have muscle cramps, or even pass out. Normally, as soon as your body starts to get too hot, it sends signals to your skin to release sweat to cool you down. But for someone like this man who can’t sweat, that never happens. He can’t cool down naturally, so it can be dangerous for him to exercise or even go outside on a hot day.
This dad has a son who can’t sweat. He just gets too warm and starts to feel tingling sensations in his limbs, and then it spreads from there. He uses water misters and ice to stay cool, but when his son gets too hot, he has to jump in the pool or pour water on himself.
For people who can sweat, it’s like your body has a natural way of cooling itself down. In fact, sweat is mostly water. So, in summary, sweating may be uncomfortable, but it’s also really important. It’s one way our bodies maintain the right temperature. People who can’t sweat have to find other ways to cool themselves off, or they may be at risk of overheating.
That’s all for this week’s question. Thanks, Aditya, for asking it! Now for the next episode, I reached into my question jar and found three questions submitted to me that I’m thinking about answering. When this video is done playing, you’ll get to vote on one. You can choose from: How does a song get stuck in your head? Do monkeys eat anything besides bananas? Or how do scientists figure out the answers to so many questions?
So submit your vote when the video is over. I want to hear from all of you watching. There are mysteries all around us. Stay curious, and see you next week!
