A new study from researchers claims yawning helps cool our brain and you’d be amazed by what you see
A yawn is a reflex of simultaneous inhalation of air and stretching of the eardrums, followed by exhalation of breath[Wikipedia] but there could be more as scientists are now claiming that yawning is actually the body’s physiological mechanism in cooling down the brain.
Researchers believe yawning is contagious and help’s in increasing the heart rate, blood flow and uses muscles in the face to maintain a lower temperature of the brain. So, there won’t be much of an explanation here, you can grab a cup of popcorn, watch the video and let us know how many times you yawned during the video. Now, how’s that?
