Know how to cry
From a medical point of view, tears are a kind of liquid secreted by lacrimal glands, which are located above the eyeball. The average person blinks about 13 times per minute. Every time he blinks, his eyelids bring some tears from the lacrimal gland. When people blink, tears can clean their eyes, such as washing away foreign objects and irritants.
Study tears
Now, some experts are studying other functions of tears, such as the relationship between tears and emotions. As we all know, when a person is very sad and painful, he will burst into tears, which is manifested as "a snot and a tear".
This is because too many tears are discharged from the body through the nasal cavity through the lacrimal canaliculus, lacrimal sac and nasolacrimal duct. Experts from the Psychiatric Laboratory of St. Paul-Ramsey Medical Center in the United States found that tears can relieve people's sense of depression. Through the chemical analysis of tears, they found that tears contain two important chemicals, namely leucine-enkephalin complex and prolactin.
Interestingly, these two chemicals only exist in tears affected by emotions, but they are not detected in tears stimulated by onions.

Tears can clear away melancholy chemicals.
Therefore, they believe that the discharge of tears from the human body can remove the chemicals accumulated in the body that cause depression, thus reducing psychological stress and keeping the mood comfortable and relaxed.
Experts in this laboratory conducted a one-month "crying experiment" on more than 200 men and women. As a result, 85% of women and 73% of men said that they felt much better after crying, and the average depression test was reduced by about 40%. The experimental results also show that the ability of men to cry is obviously inferior to that of women, and the number of crying is only 1/5 of that of women. 45% of men only cry in circles and don't fall, but most women cry and only 6% of women don't fall.

Experts believe that it is not advisable to suppress crying blindly.
Because men are used to controlling their feelings and tears, they are more likely to suffer from mental stress-related diseases such as ulcers than women. Therefore, people should change their attitude towards crying, because crying is an extremely natural physiological phenomenon, and holding back tears is harmful to health. Crying and laughing are both ways to vent their feelings.

Experts from the tears analysis laboratory in tulane university, USA, found that tears contain a very complex chemical substance, and its composition will change with human diseases and drug treatment. Therefore, tears can accurately reflect the health status of the body and can be used to detect whether athletes take illegal drugs.
An expert who specializes in the diagnosis of diseases with tears at Columbia University in the United States has found a way to take out the tears of the subjects painlessly, conduct extremely accurate and meticulous analysis, and find out the disease and the cause. These studies will further uncover the mystery of tears, apply them to clinic and benefit mankind.
