First time post sorry if it’s a dumb question

Muscles quivering is a strategy the body uses to warm itself up a little. It’s called shivering. So, everything chatters. It’s just that your legs and arms don’t have any hard parts that bump together.
Because your body starts moving all your muscles to contract and release to warm your body up. That’s why you shiver. And that also makes your teeth chatter. Because the contractions are involuntary and therefore not controllable.
Our bodies like to maintain a constant temperature. When you’re cold, your body tries to warm itself up by shivering. Shivering makes your muscles tense up relax in a fast, rhythmic fashion, and this movement generates more body heat. When the muscles in your jaw tense up and relax, it makes your teeth clack together.
Teeth chatter as a natural response of the body trying to warm itself up when you’re cold. The rapid opening and closing of the jaw causes the teeth to hit against each other, creating the chattering sound. This involuntary action is part of the body’s shivering response, which generates heat through muscle activity to raise body temperature and combat the cold.
