With the cold well and truly here, so is regular bouts of chattering teeth.
But have you ever wondered why your teeth react in such a way?
There are a few reasons why but the main reason is for your body to protect itself.
The body is simply protecting its core temperature, just like it does when you get the shivers.
Medical Daily explained the phenomenon as “a method of homeostasis. When your body gets too cold, the hypothalamus - the part of the brain in charge of controlling temperature - instructs your body to go into survival mode.”
To be exact, the muscles in your jaw expand to create heat and in turn cause the good old chattering sensation.
So take it as your body warning you that is feeling cold. This allows you to know it's time to rug up.
Smart, ain’t it?
