Yawning is a completely normal and natural process that accompanies us throughout life. We yawn from the moment when we are still in the womb, and even our pets, such as kittens, are no exception. But why do we do it and how it helps our body?
Yawning usually occurs in moments of fatigue or drowsiness. But in reality there are other factors that can encourage us to do this process. For example, we yawn in suffocating rooms with low oxygen or stressful situations. A yawning in such cases may be the answer to the need to restore the balance of oxygen in the body or get rid of excess tension. Yawning has several useful effects. If we find ourselves in a suffocating room or in a place with a low oxygen level, a deep breath while yawning helps to ventilate the lungs better and provides the body with the necessary oxygen. This makes it possible to breathe deeper than usual. But when we feel fatigue, yawning acts as a kind of "restart" of the body. During fatigue, our muscles can undergo tension, and yawning helps to relax the muscles and relieve this tension by restoring strength. There is another theory that yawning helps cool the brain. Intense mental activity can overheat the brain, and deep yawn allows you to pass the flow of cool air through the upper palate, which can lower the temperature in the brain and help maintain its optimal work.
Therefore, yawning is not only a manifestation of fatigue, but also an important protective reaction of the body. Restoration of oxygen balance, decreased muscle tension and cooling of the brain - all this helps the body to function more effectively. So do not be afraid to yawn, it is quite normal and even good for health.
