Why a man got yawning by seeing a person who yawns?

Yawning is associated with tiredness, stress, overwork, lack of stimulation, or boredom. Yawning can also be a powerful non-verbal message with several possible meanings, depending on the circumstances. In humans, yawning has an infectious quality, i.e. seeing a person yawning, or just thinking of yawning, can trigger yawning which is a typical example of positive feedback. Infectious yawning has also been noted in chimpanzees. The primary reason behind yawning is to control brain temperature. It cools off your brain, much like a fan cools off the inside of a computer. The claim that yawning is caused by lack of oxygen has not been substantiated scientifically. Some claim that yawning is not caused by lack of oxygen, for the reason that yawning allegedly reduces oxygen intake compared to normal respiration. Another speculated reason for yawning is nervousness and is also claimed to help increase the state of alertness of a person-paratroopers have been noted to yawn in the moments before they exit the aircraft.


Does yawning make you tired?

Yawning is not the cause of tiredness, but rather a response to fatigue or boredom. When you yawn, it can increase oxygen intake and help regulate brain temperature, which can help improve alertness and focus, temporarily reducing feelings of tiredness.


Why can't you hear as well while you're yawning?

Some studies say that yawning occurs when your brain is overheated. Maybe your hearing decreases because of this heat? Yawning is still a mystery.


Can you stop yawning?

no, you can't stop yawning because if you try hold it in it will automatically come out yours nose holes.
