Anthropologists have discovered that among the many types of primates, humans are the only members who cry and shed tears.

Tearing is a simple behavior that people are born with. There is no need to learn. Everyone knows it. It is instinctive like heartbeat and kidney excretion, and spontaneous like sighing and sneezing. Modern medicine believes that tearing has a great relationship with three factors. The first is the excessive secretion of tears caused by the cornea, iris, ciliary body and other tissue diseases or the stimulation of factors such as smoke and chemicals.

The second is due to obstruction of the lacrimal system, the normal secretion of tears can not be smoothly discharged into the nasal cavity, resulting in reflux and overflow.

The third is due to the lower eyelid ectropion, the lacrimal puncta cannot be close to the lacrimal caruncle, and the tears cannot enter the nasal cavity from the lacrimal canaliculus, and thus overflow. And our focus today is mainly to discuss topics with normal tears other than eye diseases.

2. The act of tearing itself is good for the eyes

In addition to the view of traditional Chinese medicine, crying often leads to a series of vicious circle diseases, and even blindness. The conventional view is that crying often can also cause some of the following injuries, so you might as well take a closer look:

1. Eye pain
Crying too much can easily cause eye pain. In the process of crying, the muscles around the eyes are in a state of fatigue, and tears continue to flow out, and the lacrimal glands are also heavily burdened, causing eye pain.

2. Swollen eyes
Crying too much can easily cause swollen eyes. When crying, tears put a burden on the lacrimal glands, and affect the water metabolism around the eyes, resulting in swelling of the eyes.

3. Blurred vision
Crying too much can easily cause blurred vision. If you cry too much, the eyeball muscles are in a very tired state, the ciliary muscles continue to contract, and your vision will be blurred. At this time, as long as you rest well, it will not cause permanent damage.

4. Rubbing your eyes will damage your eyes
When crying, if you wipe or rub your eyes with your hands or paper towels, this may damage the cornea on the surface of the eyeball. If you use excessive force, it may cause corneal rupture and infection. If not treated in time, it may cause corneal ulcers. The eyes may be severely painful and crying ceaselessly, which can cause severe damage to eyesight and, in severe cases, blindness.

8. SummaryWhen it comes to tears, most people may think of hurt. However, William Fry, a psychologist at the University of Minnesota in the United States, conducted a more comprehensive study on tearing behavior from the perspective of psychology and biochemistry. He divided tears into reflex tears (such as being stimulated by onions) and emotional tears. In 5 years, Fry’s statistics show that in a month, men rarely cried and shed tears more than 7 times, while women cried more than 30 times. At 7-10 in the evening, gathering with family and friends, or watching TV, is the time when emotional tears occur most frequently. Fry collected the subject’s tears in a special small test tube, and analyzed and tested the tear samples. He found that emotional tears contained more protein in tears, while reflex tears contained less protein. Among these complex proteins, there is a chemical substance that may be determined to be similar to analgesics.

Based on this result, Frye speculated that tearing may be an excretion behavior, which can eliminate the biochemical toxins caused and accumulated by the human body due to emotional stress; if these toxins are not discharged through tears and stay in the body, it will be harmful to health; emotions; Sexual tears excrete toxins and restore the psychological and physical balance of the tears, which is beneficial to health. Therefore, I think proper tearing is actually a detoxification behavior for the eyes, and it is beneficial.

3. Does crying often hurt the eyes?

If a small amount of crying to remove toxins has a cleansing effect on the eyes, then cry often, pay attention to the keyword “always”, it is no longer an act of crying alone, it has become emotional problems, and emotional problems often hurt It is the internal organs.

Traditional Chinese medicine believes that the liver governs anger, the heart governs happiness, the spleen governs thought, the lung governs sadness, and the kidney governs fear. Sweat, tears, tears, salivation, and saliva are all the essence of the human body. If they wear too much, the body will have problems.

Therefore, if a person sheds tears frequently, he will “snap the essence”, and will cry blindly over time. In addition, there is a phenomenon that everyone can pay attention to. Generally speaking, people with strong lung qi will cry very loudly. If a person’s lungs are weak, the crying voice will be relatively low. If you cry frequently, it will hurt your lung qi. The lungs dominate the skin. People with weak lungs generally have very skin. Is not good.
