Did you know why we yawn?
The most popular, but likely wrong, theory is that yawning increases levels of oxygen to the brain. A more plausible theory: Yawning cools the brain down. A study conducted on mice found that as mice sucked in air, their jaws stretched—this increases blood flow to the brain. This combination of cooler air intake when yawning mixed with the blood flowing to the brain is thought to eventually cool the brain down.

2Yawning is a fascinating phenomenon! While the theory of increasing oxygen levels is popular, a more plausible theory suggests that yawning helps cool down the brain. Research on mice showed that yawning increases blood flow to the brain, and the intake of cooler air during yawning contributes to this cooling effect. It's still an area of ongoing study, but it's intriguing how yawning may serve a purpose beyond just tiredness.

10while the exact reason why we yawn is still not fully understood, it's clear that yawning serves an important physiological function in the body. It's also a contagious behavior that can be triggered by seeing or hearing others yawn, which is thought to be a social and emotional response.
