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.
Some studies say that yawning occurs when your brain is overheated. Maybe your hearing decreases because of this heat? Yawning is still a mystery.
no, you can't stop yawning because if you try hold it in it will automatically come out yours nose holes.
Yawning when you see someone else yawn is thought to be a form of social bonding or empathy. It may be an unconscious response triggered by seeing someone you are connected to engage in a behavior, leading to a contagious yawning effect.
Yawning is a sign that the brain is not getting enough oxygen, usually this is because the body is transitioning from sleep to being awake; or that there is not enough fresh air in the room. According to recent studies by scientists, the reason for this infectious yawning is because (their theory) it's a way of us communicating emotionally to each other, and we don't really think about it. It's all physiological, and some things, we may never understand. Yawning is associated with tiredness, stress, overwork, lack of stimulation, or boredom.

Yawning while singing can happen because singing requires deep breaths, which can trigger the body's yawning reflex. It's a natural response to help regulate oxygen levels and keep your vocal cords relaxed.
