moe darklight said:this is my own personal observation so there's no science or research behind it... but I've always noticed that yawning feels more like stretching than breathing for oxygen. We always stretch our muscles when we just wake up or have been passive for a long time (like our back and neck and legs), these are also the times we most likely yawn... could yawning simply be a way of stretching those internal muscles and jaw muscles?
Yawning is a reflex that helps to regulate the body's oxygen and carbon dioxide levels. It is also believed to be a way to cool down the brain and increase alertness.
Yes, yawning is considered to be a socially contagious behavior. Research shows that seeing, hearing, or even thinking about yawning can trigger a yawn in others.
While the exact purpose of yawning is still not fully understood, it is believed to have various benefits such as increasing alertness, bringing in more oxygen, and releasing tension in the jaw and facial muscles.
The exact trigger for yawning is still unknown, but it is believed to be linked to factors such as fatigue, boredom, and changes in brain temperature or oxygen levels.
Yawning may have some health benefits such as improving circulation and increasing heart rate. It may also help to release stress and tension in the body.
