The Theories of Yawning

January 18,2018

The most scientifically backed theory of why we yawn is for brain temperature regulation. Studies show that people yawn less in winter as the temperature is moderate and cool enough for our brain. Another leading theory of why we yawn is to wake the body up. The motion helps stretch the lungs and their tissues; it also allows the body to flex its muscles and joints and force blood toward your face and brain to increase alertness. One also yawns when there are any blood clots in your brain. Yawning helps to cool your brain down from that clotting.

The most common reasons as to why people yawn are

• Tired: Your brain is slowing down, causing its temperature to drop

• Bored: Your brain isn’t feeling stimulated and starts to slow down causing a temperature drop

• Contagious: You are in the same environment as the one’s whom you saw yawn
