The advantages and disadvantages of crying on the body

Crying is a way to vent emotions, sometimes expressing sadness and sometimes expressing happiness. It is a normal emotional expression of human beings. Moderate crying is a way to vent stress, which can release stress and reduce the occurrence of diseases. At the same time, crying is an expression of true feelings and can enhance relationships between people.

Generally speaking, crying is not bad for your body, but if you cry too much or stay in a crying state for a long time, it will be harmful to your body. From a scientific point of view, crying has a protective effect on people's psychology and body. Because people will cry when they are in extreme pain, and crying is a way of venting, so people's mood will improve after crying. Moreover, tears have a bactericidal effect, so crying can also moisturize the cornea and clean the eyes. In addition, tears also have a protective function. When foreign objects enter the eyes, tears will be secreted naturally and instinctively, which can wash away the foreign objects in time.

However, crying also has negative effects. For example, crying can cause a person's breathing to become irregular, sometimes heavy and sometimes shallow, which can easily lead to irregular heart rhythm. In addition, excessive crying can damage a person's eyesight, and in severe cases can cause blindness.

Sadness is harmful to health, but crying when you are sad is good for your health. Psychological experts have found that the tears shed when people are sad contain high levels of protein. This protein is a harmful substance produced due to mental depression. The accumulation of depressive substances in the body is harmful to human health. Experts from the Psychiatric Laboratory at the St. Paul-Ramsey Medical Center in the United States found that tears can relieve people's feelings of depression. Through chemical analysis of tears, they found that tears contain two important chemicals, namely, enkephalin complex and prolactin. It only exists in tears shed due to emotional influences, and cannot be detected in tears shed due to stimulation such as onions. Therefore, they believe that tears can remove the depression-causing chemicals accumulated in the body, thereby reducing psychological stress.

However, crying should not exceed 15 minutes. Once your depressed mood has been vented and relieved, you should not cry anymore, otherwise it will be harmful to your body. Because the human gastrointestinal function is extremely sensitive to emotions, if you are sad or cry for too long, the movement of the stomach will slow down, the secretion of gastric juice will decrease, and the acidity will decrease, which will affect your appetite and even cause various stomach diseases.
