  • Is it a result of oxygen deprivation in the brain or simply a reflexive action? Learn more about the causes and triggers of yawning in this informative article.

The article from the Times of India discusses the common belief that yawning is a response to oxygen deprivation in the brain. However, it explains that this theory has been largely debunked by scientific research. Instead, yawning might serve multiple functions, including cooling the brain, regulating arousal levels, or even social signaling. Studies suggest that yawning could help in thermoregulation by allowing for a rush of cool air into the nasal passages, which in turn cools the blood flow to the brain. Additionally, yawning might occur during transitions between different states of alertness, like waking up or preparing for sleep, rather than solely due to a lack of oxygen. The article also touches on the contagious nature of yawning, suggesting it might be linked to empathy or social bonding, although the exact reasons remain under investigation.
