As per researchers from University of Arizona and Princeton……Yawning is meant to cool your brain….or regulate brain temperature…. So Yawning is not linked to tiredness……………………

The researchers found yawning is more likely when the temperature outside is less than the temperature of the brain….Their argument is that keeping your mouth agape helps regulate the temperature of the brain by exposing the roof to cooler air. Cooler brains have been linked to alertness, which might help explain why we yawn when we’re tired…..to cool

Nice Work…..Special thanxs to researchers of Princeton and Arizona…
