Why am I in tears today, and why are we in tears

Why do we shed tears?

Sad? If yes, let's cry.

Some people say that you feel better after crying, and many scientists believe that this is an important clue to unravel the mystery of tears.

Above the outer corner of the eye, immediately next to the eyebrows, there is a gland that secretes tears, called the lacrimal gland.

The lacrimal ducts are the size of almonds, but these miniature factories produce a steady stream of tears.

The lacrimal gland secretes tears all the time, and even when you read this, it doesn't stop working.

Tears rinse the eyeballs and keep them clean and bright at all times.

Tears come out of the channel in the outer corner of the eye, and when you blink, the eyelids spread the tears evenly over the eyeball.

This is very similar to the working process of wiper blades on a windshield.

The tears then flow down the drain in the inner corner of the eye and along another channel to the area behind the nose, where the tears are absorbed by the body.

If you get sand in your eyes, it's a different story.

In order to quickly remove foreign bodies from the eyeballs; The tear glands secrete tears, and when they are dry, tears gush out from the edge of the lower eyes and face.

At this point, you complain, "My tears are not the same as the tears that come with crying, which are usually caused by strong emotions or severe pain."

Half of the reasons for crying are related to sadness, but sometimes people cry because of joy, anger, or fear of confession.

So what's the use of these tears that don't have a cleaning function? In fact, these tears are what make us "feel so much better".

The main ingredients of tears are water, oil, salt, and sodium carbonate (aka baking soda used to steam steamed buns), so if the tears run down your cheeks and into your mouth, you will feel that it is salty.

Human. Tears are not the saltiest of the sea, but the tears of seagulls that live at sea and feed on turtles are the saltiest because they have a lot of salt in their bodies.

Too much salt can be harmful to the body, and eye protection helps the body to get rid of the excess salt.

Birds shed tears to expel salt, so do people shed tears to expel a certain substance? This speculation seems reasonable.

When we are emotional or in severe pain, a chemical is produced in the brain to signal excitement or sadness, and a special stress hormone is produced in our body.

Scientists who study crying have discovered this stress hormone in their eyes, so crying can help us flush out the chemicals that make us feel emotional.

As these chemicals are excreted from the body, we also gradually calm down.

Many people feel that their spirits are lifted a lot after crying, as if the tears washed away the brain.

So, while no one wants to be a crybaby, proper crying is good for health.

First of all, it is normal for people to cry, and now let's analyze why people cry based on 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, when people's feelings are in place, they will shed tears when they are sad. 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 shadows, and the tears that are affected by the outside world are very different from the tears when they 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 make a lot of money.

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

As a person who has just copied and cried inexplicably, he said that he felt very comfortable. At the moment of crying, I thought of the nearest one.

I came to DAO Shanghai alone, thinking of my failure in the graduate school entrance examination last year, thinking of arguing with my friends in college, and thinking of junior high school. Then the more you think about it, the farther you go.

In fact, this is because grief can infect the body and mind and seep into the bone marrow.

The more you cry, the more sad you become, at first you cry for no reason, and later, suddenly there are thousands of reasons to cry, and the more you cry, the more you feel sorry for yourself.

However, it is not unreasonable for girls to have developed tear ducts. Studies have shown that the average life expectancy of women is longer than that of men, and one of the big reasons is that women love to cry, so the tear glands are developed, and the pressure is released correctly, which will naturally prolong the life span of humans.

After I knew this, every time I cried in the future, I would not deliberately restrain myself, but would allow myself to be sad and cry. Because it's the body telling me that it's time for you to cry and rest. After crying, you will feel very comfortable, you will be much calmer, and your heart will figure out a lot.

Human beings can't be strong all the time, because even the spring needs to be contracted in order to play higher next time.

So, the next time my friends cry, cry. In life, we need to be happy most of the time, but sometimes, we also need to be sad, be kind to ourselves, let sadness flow through our bodies slowly, and then slowly flow away, leaving our washed selves.

Tears are water after all, and goodness is like water.

Because when you grow up, there are more and more injuries

Thoughts, then.

There will be trouble

The heart of gain and loss, will cherish everything around them, then when the power is lost, of course, it will be very sad, and everything can not be really open-minded, can do nothing regardless of sadness or joy, so when you encounter some difficulties or bad things, you will feel sad, and then cry, this is very normal, everyone is often more intense than the impact on the heart, so you are not so happy when you get something, But once you lose it, then it can be extremely sad!

When you are in a hurry, you are in a hurry to cry because you are anxious about this matter, so you will shed tears, and you will shed tears when you keep your mouth open, which should be caused by the lack of liver qi, and you can find a Chinese medicine doctor to recuperate.

Good luck with your studies!

Tears. There will be a lot of emotions. Sometimes it's joy. Tears flowed. Sometimes it is. Tears of sadness. Sometimes it is. I feel inexplicably annoyed in my heart, and I will shed tears. It's windy again, and tears will be shed.

Is there something sad, or it is possible to look at the computer and mobile phone for too long.

Normally, I would cry in that situation, physiological reflection, it's not a big deal, just sleep and get up.
