Isn't that kind of annoying when you are cold and
you can't stop from chattering and shaking? All
that chattering is because your body is trying to
warm itself up before it gets too cold. Our body
likes to keep itself at a nice warm 98.6 degrees
Fahrenheit. However, if we go outside on a cold
day without warm clothing we start to get cold.
Even if our body temperature drops a few degrees
it can put us in danger (this is called
hypothermia.) So even before our temperature
drops, our body starts to protect itself by trying
to warm itself up. Your skin can sense how cold
the air is and tells your body that it needs to
start warming up before it gets too cold! By
shivering, our body can produce heat. Shivering is
caused by your muscles getting tense and then
relaxing really quickly over and over again. Your
teeth chatter because your face muscles are
shaking trying to warm it up.
