Imagine your body is like a car engine that needs to stay cool while driving. When it gets very hot outside, your body has to work extra hard to keep you safe.
How Your Body Cools Down
When you play outside in the heat, your body turns on its built-in air conditioner: sweat. Sweat is water that soaks your skin and then evaporates. Think of sprinkling water on a hot sidewalk; it cools down fast. This evaporation takes heat away from you. But if it is too hot or too humid, the water cannot dry properly, and you might feel sticky and tired.
When Heat Becomes Dangerous
If you stay in the heat for too long, your body can get into trouble. You might feel dizzy, have a headache, or feel like you want to nap. This is called heat exhaustion. Your heart beats faster to pump blood to your skin to help cool you down. If you do not rest or drink water, it can turn into heat stroke. This is a serious emergency. Your body temperature gets too high, and your brain gets confused. It is like a computer that overheats and freezes. You must move to a cool place, drink water, and rest.
Remember: Heat is invisible, but its effects are real and can be dangerous.
