Why do people cry and how does it work?

The first thing to explain is that it is common for people to cry, so let's analyze why people cry in common sense. As the saying goes, men don't flick when they have tears, and it is rare to see men crying, but you can see women crying every day, why do women cry more than men?

1 Tears are caused by emotional pressure, that is to say, when people's feelings are in place, when they are sad, they will cry out and cry. Both happiness and sadness contribute to the release of this chemical compound. Or the tears that fall from the cold air, wind, sand, or cold, and the tears that are affected by the outside world are very different from the tears that are sad.

2 Under normal circumstances, the tears secreted by a person during the day have the effect of moistening the conjunctiva and cornea of the eyeball, and part of the tears secreted are evaporated by the temperature.

3 Adult men feel that they are stronger than women, so there has always been a saying that "men don't flick when they have tears". The "normal" crying behavior of men and women proved that women did cry more often, on average five times more than men. Women cry 5 out of 10 times because of tears, while men only account for 29

After understanding the basic mechanism of human crying, let's take a closer look at the question of why people cry when they know that crying can't solve the problem (this place is a bit lame).

First of all, everything is not so absolute, and sometimes crying can still solve part of the problem. For example, children's crying can achieve goals that they usually can't achieve, such as food, toys and other things that they usually like; A woman's crying can be a companion's comfort; The crying of adults can win everyone's sympathy; Even the emotional crying of street beggars can reap a lot of benefits, etc.

But crying can play a role in certain situations of relatives, friends or certain situations, but it is definitely not omnipotent, crying in front of strangers or people who lack empathy, in exchange for only indifference, ridicule, and only the help of weak souls under the contemptuous gaze.

And a person who knows that crying can't solve the problem, and keeps crying, must be a person who is emotionally rich and delicate, sensitive and fragile, weak and introverted, and unwilling to face difficulties. But it's good to admit that you love to cry!

When you're sad, when you're uncomfortable, when you're desperate, cry if you want to. American scientist Ferrey said that people do not cry when they are sad, which is harmful to their health, which is equivalent to chronic suicide, and the prevalence rate of people who do not cry for a long time is twice as high as that of people who shed tears.

See! Crying is not useless.

However, after crying, remember to wipe away your tears and tell yourself: "Moscow does not believe in tears!" Then find a master for guidance, ask the wise man for help, and find a way to solve the problem, which is not in vain for us to cry!

Anthropologists have found that among all animals, humans are the only ones who can shed tears, and tears, as something that humans are born with, do not need us to learn, and are as natural as sneezingWhy do people weep? What is the biggest effect of tears? Joy and sorrow are very common for everyone, even when they are happy or excited, they will shed tears, it has the effect of washing, lubricating and sterilizing.

Tears are a liquid that flows from a person's eyes when they are sad or excited, and the taste is slightly salty. It is said that joy, anger and sorrow are human nature, even people with strong personalities will shed tears, and people will cry when they are excited or happy, as if tears have become a symbol of emotional changes. But when our eyes are filled with a lot of dust, the tears that come out at this time are not emotional changes.

When other businesses such as dust fall into the eyes, the tears that come out will wash these things away and have a germicidal effect.

According to some surveys, in addition to containing about 90% of water, tears do not contain a large amount of immunoglobulins, lysozyme and many other antibacterial substances, their main role is to inhibit the growth of bacteria, can destroy the cell wall of bacteria, so that bacteria dissolve and die. In addition, tears also have the effect of lubrication, tears will form a layer of about 2 to 3 microns on the surface of the cornea, which can not only keep our eyes moist, but also increase the humidity of the eyeball, keep the eyeball moving, flexible and free, so as to reduce the damage to the eyes and alleviate the harm caused by astigmatism.

According to statistics, a man will not cry more than seven times in a month, while a woman will cry more than thirty times, and the saltiness of tears shed when sad is several times higher than that of tears shed when excited and happy, so this verifies what we often say: women are made of water, and the formation of tears is inseparable from people's joys, sorrows, and sorrows, tears can not only rinse and dilute, but also play a role in sterilization and disinfection.

The main reason why people shed tears is because people have tear glands. The biggest effect of tears is to wash our eyes. Remove some of the dirt from our eyes. It can also better lubricate our eyes and protect our eyes.

Among all animals, human beings are the only ones who have tears, and a person will shed tears when I am sad and excited, and 90% of the content of tears is water, so it has the effect of lubrication, sterilization and disinfection, and can remove toxins from the body.

Tears are good, they can relieve sadness, sadness, release endocrine hormones, and emotions will be relieved, so that people are not so sad.

Tears are a way of emotional catharsis, and the biggest role of tears is to keep the face moist.
