Why does my child keep yawning?

If a child yawns frequently, parents should pay attention to whether the child’s sleep is not good, or if the child goes to bed too late at night, so the child is not in good spirits during the day and keeps yawning. Parents must help correct this situation of their children and not allow them to go to bed late. This is not good for children's health, because staying up late is very harmful to the body. Staying up late often will also shorten a person's lifespan. It can be said that staying up late is of no benefit.

Yawning often occurs after a long period of slow or shallow breathing. Common causes of yawning include excessive fatigue, tension, sitting for a long time, concentrating on homework or reading, a too tight belt, an overheated room, poor ventilation, etc. People often yawn when leaving cinemas and other amusement parks. This is not a sign of boredom, but a result of sitting still for too long and breathing shallowly for a long time.

When people yawn, they open their mouths wide to let as much air out of the body as possible in order to exhale carbon dioxide and inhale oxygen. As you yawn, a stream of air is exhaled forcefully from your mouth. The muscles in the cheeks, tongue, and throat tense and contract, increasing pressure in the mouth and nasal cavity. The increased nasal pressure will temporarily block the nasolacrimal duct from draining tears. The "sewer" is blocked, the tears cannot flow down, and more and more tears accumulate in the eyes. Your eyes will be filled with tears, and finally the tears will burst out and flow down your face.

If you keep yawning but can't get into a sleeping environment right away. You can try some ways to refresh yourself, but don’t drink tea or coffee, as they will become addictive. You can stand up and do some light exercise to relieve your sleepiness, and you won’t feel so uncomfortable. In addition, it is best to cover your mouth with your hands when yawning to prevent dirt from falling into your mouth.
