Why do people cry when they are sad?

When you are sad, it is also when you are needed the most! There you are again!

Because if you don't feel sad, you won't have tears.

Because I have come to the country to be sad.

I suddenly wanted to cry.

Is it something that comes to mind, sometimes the tears are very low, and it's easy to cry and ask questions when you think about it, but there is no sadness at all.

The answer is that you suddenly thought of something, but you don't know that you can't control the tears when you ask the question, and you don't know why you are sad to answer Sometimes you don't need a reason to cry, and suddenly a very happy person, looking at something, something, will have a sudden change in mood.

I've also experienced such a situation, that is, looking at a thing that is so happy, and suddenly I feel that I don't know why I am happy when I am happy.

Somewhere in the nervous system of the brain, the role of internal and external factors. It's okay to cry, this process is going to happen, but don't cry for too long, your eyes will be swollen, your nose will be red, and you will be bleeding ·· There is a certain amount of damage to the image for a certain period of time.

Because it's uncomfortable....Because human beings are animals with feelings and feelings...Crying is not cowardice....It's for venting....It's to stand up better....Go ahead.

Tears have nothing to do with sadness, if you are too happy, there will be tears, mainly because the human body is too excited, there will be tears.

The lacrimal glands are well developed. Subconsciously. Brain control.

I don't want to explain it to you in such a scientific way, because I feel like you're asking this question not to know why you're crying, but to emphasize that you're sad right now, right? You shed tears, maybe it's loss, maybe it's failure, but no matter what, you're always in pursuit of happiness, just like love, everyone wants to be happy all the time, but if you're happy all the time, how to experience a happier feeling, those sadness are temporary, please believe, only a small sadness will bring greater happiness!

Tears are caused by emotional stress, and both joy and sadness contribute to the release of this chemical compound. The chemical composition of tears shed by cold air, wind, or cold is very different from that of tears when you are sad.

Sadness is the same as happiness, because some very simple reason creates tears. If the feelings are strong enough, a special hormone will be released, and the person will "cry". Inevitably, this reaction makes onlookers subconsciously believe that the victim's system is losing liquid:

He or she wept sadly.
