Reason of yawning

                       Yawning

A yawn is an involuntary reflex where the mouth is opened wide, and the lungs take in a lot of air. The air is then exhaled slowly. During this time, the eardrums stretch, and the eyes may also close tight, causing them to water.

                           

Reasons  of Yawning:

The biggest reason for yawning is that when the brain gets tired of doing a lot of work, it doesn't get enough oxygen and it doesn't want it to fit perfectly if it can work properly. Due to which the brain does not get all the oxygen it needs.

A respiratory function  

Yawning may be a function of breathing. Yawns may be more likely when the blood needs oxygen. A yawn causes a big intake of air and a faster heartbeat, which could theoretically mean that it is pumping more oxygen through the body. So a yawn may be simply designed to help clear toxins out of the blood and provide a fresh supply of oxygen.

To cool the brain

Yawning may cool the brain. A yawn causes the jaw to stretch out, increasing blood flow in the face and neck. The large inhale and rapid heartbeat caused by the yawn also causes blood and spinal fluid to cycle through the body faster. This whole process may be a way to cool down a brain that has gotten too hot.
