How Does the Human Body Regulate Temperature in Extreme Weather?

Our body is like a smart thermostat. When it's cold, we shiver to warm up, it’s like shaking the inside of our blanket. When it's hot, we sweat, it's like turning on a little fan and putting wet clothes on. Our skin helps us feel what's going on outside and tells our brain when to turn up the heat or cool things down.
