Why do I cry and why do we cry

Because the years have matured us a lot, and suddenly we understand that the world is colorful.

Pure love should be cherished, don't wait until you regret it to regret it.

It's clear that you're in love with him.

Your heart won't lie to you, and if I'm not mistaken, you'd love to see her in person right now.

If you like it, chase it.

Don't let yourself regret it.

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.

When are people most likely to shed tears?

First of all, this tear refers to the spiritual, not the material, so I cut the onion, the eyes into the sand, yawn and sneeze and so on, purely spiritual to make ** tears.

I have summarized the following types of causes of tears and crying:

1. Sad and sad.

It's mourning, the kind that is more than the death of the heart, extremely sad, sad, and this type of tearing is not a few.

For example, when you see your loved one in pain but you can't do anything about it, you can't help but burst into tears when you see your loved one leave.

2. Grievances and misunderstandings:

This type can easily make people cry, and the whole world thinks that you are wrong, but in fact you are exactly right, and you want to cry at that time. Being misunderstood, especially by lovers, loved ones, and I want to cry too.

Examples: too many to mention.

3. Touched by sympathy.

Seeing moving events, hearing stories of feelings, and thinking of some similar experience in the past, tears can easily come out. This type of woman is more likely to cry, watch movies, and watch TV reports. Examples:

Moved by the Chinese selection party, watching a tragic movie, knowing that it is fake, but still crying.

4. Bullying and insulting: Being bullied, insulted, especially when you are exposed by your opponent and you are incapable of arguing, you may not shed tears at that time, and after the incident, you will secretly feel sad.
