How Does GCSE Biology - How We Control Our Body Temperature Work?

Our body is like a little thermostat that keeps us just right, no matter if we're outside playing or inside eating ice cream.

When it gets cold, our body starts to work hard to warm up, kind of like when you wrap yourself in a big cozy blanket. Your blood vessels get smaller, which is like closing the windows in your house so the cold can’t come in. At the same time, your muscles start to shiver, which is like jumping around to stay warm.

When it gets hot, our body wants to cool down, just like when you turn on a fan or take off your sweater. Your blood vessels get bigger, letting more blood flow near the skin so heat can escape. You might even start to sweat, which is like your body using little water bottles to cool itself down.

Your body is always working in the background to keep you just right, no need for magic!
