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.

to give the brain fresh air!
Yawning is a natural reaction and can not be prevented, but it is COMPLETELY normal. Yawning is caused because not enough oxygen is getting to the brain. Thus, it usually happens when an individual is sleepy or not thinking clearly.

Experts suggest that yawning may actually provide a competitive advantage, as it stimulates the precuneus, a structure in the brain that affects consciousness and attentional focus. Yawning also regulates the temperature and metabolism of the brain.
