Yawning can bring you these unexpected surprises

Normally, we always say that "yawning is contagious" and "yawning means that the body is lacking sleep and is in a sleepy state." Is this really the case? So far, no one has been able to explain clearly why people yawn. Someone once calculated that each yawn takes about 6 seconds. During this process, a person can close his eyes and ears, and the nerves and muscles of the whole body can be completely relaxed. But some people also say that yawning is a sign of brain hypoxia. By yawning, more carbon dioxide can be expelled, more oxygen can be added to the blood, and people can be more energetic.

There are many different opinions about yawning, but from this we can see that no matter which one, yawning will bring certain benefits to our body. Today we will see what unexpected benefits playing yawn can bring us.

1. Yawning is a sign of fatigue

Yawning is a physiological phenomenon. It not only helps expel excess carbon dioxide from the body, but is also a protective response of the human body. When people are sleep deprived or tired, they will yawn frequently. This is a reminder that your brain and organs are tired and you need to go to bed and rest quickly, or that your work is too stressful and you need to relax and rest for a while to recover.

2. Yawning wakes up the brain

When we wake up every morning, we always yawn a few times. Many people think that this means they are not fully awake yet. In fact, in addition to this, yawning can also promote the various functional areas of the cerebral cortex from inhibition to excitement, allowing the cerebral cortex to work normally. Every time you yawn, there must be a deep and long inhalation, which is conducive to more hot oxygen entering the lungs and reaching the blood. In addition, yawning can drive oxygen-carrying blood to the brain, improving brain efficiency, which is especially suitable for mental workers.

3. Yawning promotes facial muscle activity

On average, people yawn many times a day. When you yawn, the entire face will be moved, and the throat muscles will move and increase muscle strength. When you yawn, the nerves and muscles of the whole body will be relaxed and in a state of complete relaxation. It can also reduce snoring symptoms caused by relaxation of the throat muscles.

4. Yawning cools the brain

Have you ever felt a brief sense of coolness after yawning? In fact, the human brain is extremely sensitive to temperature, just like a computer, and must be kept cool to work effectively. Yawning causes the walls of the maxillary sinus to expand and contract like a bellows, pressing air toward the brain and lowering brain temperature. This discovery may bring some hope to patients with insomnia, migraines and even epilepsy. Insomniacs often have problems regulating their body temperature, and discovering the secret of yawning may also help insomniacs.

5. Benefits of yawning for men

For men, yawning and penile erections are both controlled by a type of nitrogen oxide, which diffuses in the brain and can either reach the nerves that control breathing or go down to the blood vessels that transport energy to the penis, and sometimes both functions can occur at the same time.

6. Yawning makes people relax

Although a yawn lasts only a short time, about six seconds, its physiological effects are significant. During this period, a person completely closes his eyes and ears, and all the nerves and muscles in the body completely relax, thus getting a good rest both physically and mentally. Its effect is better than that of sedatives. It turns out that yawning has so many benefits. I will yawn more carefully in the future!

Yawning is a conditioned reflex of deep breathing that allows people's skin and nerves to relax briefly, so you don't need to question yawning.
