why does biting your tongue improve concentration when doing manual tasks?
In: Biology
A lot of your brain is devoted to controlling or getting info from your tongue. You’re constantly monitoring how it’s positioned, how much it’s contracted or relaxed, what sense data about your mouth it’s giving you at any particular time, and how it might have to move in order to speak. If you stick it outside of your mouth and hold it still with something other than your tongue (like your teeth), it frees up that brainpower for other uses.
