Why do we yawn ?

We take jamai to deal with sleep deprivation but the amazing thing is that jamai does not keep us awake but its purpose is something else.
Research has shown that the real purpose of taking jamai is not to provide oxygen to the brain, but to cool our brain.

Experts have revealed that exercise has nothing to do with fatigue and boredom, but rather to cool the blood in the warmer parts of our brain and improve mental performance.
According to a study published in the scientific journal Physiology and Behavior, sleep deprivation and fatigue increase the temperature of the brain.
