Our bodies are like tiny thermostats that keep us just right, not too hot, not too cold.
Imagine you're wearing a blanket on a chilly night. You feel cozy and warm. That’s your body working hard to keep you warm, just like the blanket does. But if it gets too hot, like when you’re playing outside in the sun, your body starts to cool you down, like turning on a fan or taking off a sweater.
How we stay warm
When it's cold, our bodies shiver, that’s like tiny movements inside us, making us feel warm. It’s like when you jump up and down when you’re cold, it helps you get warmer faster!
Our skin also helps. Blood vessels near the surface of our skin can expand, letting more blood flow to the outside, this makes us feel warmer.
How we cool down
When we're too hot, our bodies sweat. Sweat is like a tiny water hose that pours out from our skin, and when it evaporates, it takes heat away, just like how wet sand feels cooler after you splash it with water!
So your body is always working, like a smart little machine, to keep you just right! Our bodies are like tiny thermostats that keep us just right, not too hot, not too cold.
