Why do children yawn all the time?

We all yawn at normal times, and children do the same. Sometimes it is a normal human reaction. In life, as long as there is nothing abnormal in our body, it will generally be fine. If this happens when you have enough sleep, you need to pay attention. So why do children yawn all the time? Let’s learn more about it through the following introduction.

A yawn lasts about 6 seconds, during which time a person closes his eyes and ears, and the nerves and muscles of the whole body are completely relaxed. Therefore, it can be considered that yawning allows people to get the best rest both physiologically and psychologically, and has an important physiological protective effect on the human body. Some people believe that yawning is a sign of brain hypoxia. Through the deep breathing exercise of yawning, the human body increases oxygen in the blood and expel more carbon dioxide, making people more energetic. When people are sleepy, they often yawn continuously to remind the body that the brain is tired and needs sleep and rest, so yawning is also a method of hypnosis. When people are about to start intense work, they often yawn. This may be because the human body uses deep breathing to add more oxygen to the blood and improve the brain's activity.

In short, yawning is an instinctive reaction of the human body. Like heartbeat and breathing, it is not controlled by human will. It has a good protective effect on protecting brain cells, increasing the oxygen supply to brain cells, and improving the body's stress resistance.

Through the above introduction, we know why children yawn all the time. In normal times, we just need to observe whether the children have any abnormal phenomena. If the children often have such phenomena, we need to pay attention. It is best to go to the hospital for necessary examinations to prevent unexpected situations.
