Why, when a man is sad, he cries?

If you try to offend with the cat’s cat, risk checking the sharpness of her claws. But it will not happen at all because the cat loves a kitten. The instinct is triggered by the protection of offspring.

If you try to select bone from a hungry dog, you will cause the reaction, very similar to anger. Although in fact it is also instinct.

Animals have no emotion. But there are instincts that, tripping, resemble them. So, when the dog throws the owner, she sculits, because the attachment instinct works. When the grief occurs in a person, he cries most often. Crying is perhaps the safest way to express sadness.

In stress, the body synthesizes toxic substances: leucine enkephalin and prolactin – which are removed only with tears

The appearance of tears in humans can be divided into two types: physiological, when they cleanse the eyes from small saidels and moisturize them, preventing the cutting of the cornea, and emotional, when tears appear with a nervous shock. In stress, the body synthesizes toxic substances: leucine enkephalin and prolactin – which are removed only with tears. It is no coincidence when a person pays, he feels easier.

But the etiquette dictates that it is not good to cry in the public, and men should not show their emotions at all. Under the influence of public opinion, a person learns to suppress tears, but this does not mean that sadness goes. Negative emotions accumulate and sooner or later find another way to spill out. A person can disrupt evil on loved ones, drink an excess glass of alcohol, smoke or fight. Emotion containment is reflected on the nervous system and can cause cardiovascular diseases.

It turns out that tears are the best way to remove the nervous stress and remove harmful substances from the body. In addition, they normalize pressure, enhance the body’s resistance to infections and reduce the risk of developing diseases of the gastrointestinal tract.

They have another useful property: they affect other people. So, children often cry to pay attention. And helps! They are suitable, sorry, warmed, feed and solve their other problems. It works in adults. Another William Shakespeare called the tears of "weapons of women".
