I used to wake up in the morning and yawn violently and then my nose would runny.

It should be that there is something at home that you are allergic to, use peracetic acid to disinfect it!

Yawning is an instinctive reaction of the human body, which, like heartbeat and breathing, is not controlled by the human will. It has a good protective effect on protecting brain cells, increasing the oxygen supply to brain cells, and improving the body's ability to cope with stress. If it is occasional yawning, it is a normal reflection that frequent yawning is a lack of oxygen to brain cells1

Probably you have a lot of stress at work2Maybe you're in a state of tension all the time 3Poor sleep quality 4, whether the air in your environment is not good, pay attention to open the window for ventilation It is recommended not to think too much at night, adjust the work and rest time, and exercise more I hope you can adjust yourself.

But if you yawn a lot, it's not normal. From the perspective of traditional Chinese medicine, it is a symptom caused by the lack of heart qi and mental nourishment. It usually occurs in people over the age of 40.

In such people, the body's function decreases, and the heart qi is insufficient, resulting in yawning. You can take traditional Chinese medicine to nourish the mind. Because certain diseases can also cause frequent yawning, such as cervical spondylosis, thyroid disease, neurasthenia, etc., if you yawn for a long time without fatigue, you should be vigilant.

Thank you for the trouble to adopt!

Why do people shed tears when they yawn.

When I'm sleepy, I always yawn. When you yawn, your eyes will always be full of tears, why do people shed tears when they yawn?

Human tears are secreted all the time, flowing on the surface of the eyeball. However, there is very little tears secreted and they flow along the surface of the eyeball and in the tiny spaces inside the eyelids, so you don't feel that the tears are flowing.

However, in the blink of an eye, the tears on the surface of these eyeballs are sucked into the nasolacrimal duct, the sewer of the tears. Don't underestimate this not-so-long tube, it's the only way for tears to reach your nose. The lacrimal glands constantly secrete tears, and the nasolacrimal ducts constantly excrete tears, so people usually do not shed tears.

When a person yawns, his mouth is wide open, and he may exhale more than he can out of his body in order to exhale carbon dioxide and inhale oxygen. With the action of yawning, a stream of gas exhales forcefully from the mouth. The muscles of the cheeks, tongue and throat tense and contract, and the pressure in the mouth and nose increases.

As a result of the increased pressure in the nasal cavity, it will temporarily block the work of the nasolacrimal duct to excrete tears, and the "sewer" will not be passed, and the tears will not flow, and more and more tears will accumulate in the eyes. There will be tears in his eyes, and finally he will burst out of his eyes and flow to his face.

In fact, not only yawning can cause tears, but also when people laugh, sneeze, cough, and vomit, and the reason is the same.

Hello, it is recommended to go to the hospital for examination, there may be rhinitis.
