Why does my child yawn all the time?

If a child yawns frequently, he will soon realize that his sleep quality is poor, which leads to a bad mental state and he will yawn constantly. In addition, yawning is actually contagious, which means that when you see others yawning, you will be affected and start yawning too. This is caused by the stimulation of neurons. In fact, yawning is a way for people to relax their body and mind, but many people don’t understand it.

People yawn from the moment they are born until the end of their lives. No one can explain why people yawn. Possible mechanism: 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.

Don’t underestimate yawning, in fact, there are many benefits of yawning. Normally when we yawn, tears are secreted. Regular secretions from the eyes can help moisturize the eyes, clean the eyeballs, and prevent the eyes from becoming so dry. It is true that yawning can actually protect your eyes. But if a child keeps yawning during the day rather than at night, he or she should pay attention to rest.
