We are endowed with the ability to cry at birth, but, as adults, think tears a sign of weakness. Do I have to hold back tears, or maybe vice versa - to cry sometimes useful? After all, there are times when it is very difficult not to cry.
Crying - A fairly common phenomenon in nature. Not only people, but animals are able to cry out in pain. But only "homo sapiens" is able to shed the emotional tears . Mourning Joy or sorrow - Our special mental states cause tears Which are unconscious signals that we need the support or sympathy.
What are the tears
Every day, our eyes produce a little more than 14 grams of tear fluid. It is formed in the glands disposed around each eye. When blink tear moisture is distributed over the surface of the eye, and the surplus falls into the tear ducts. Two tubules. One is located in the inner corner of the eye and connects to the lacrimal sac overlooking the nasal cavity. That is why when we lament not only the eyes on a wet spot and nose.
So why do we still cry?
1. Tears 98 percent water. But not only. Mechanical tears For example, contain fat elements mucus proteins and antibacterial agents. They are needed to moisten the eyes, its purity and protection from infection. Mechanical tears produced by glands in all the time, but we almost do not notice them, because these tears do not flow out of their sockets.
2. Reflector tears secreted in response to stimuli. That reflex tears we cry when we cut the pungent onions. They are almost entirely composed of water, because it is necessary, first of all, in order to rapidly flush eye.
3. Sadness and heavy experiences, as well as a state of euphoria, as is well known, easy to cause tears . The densest among emotional tears - the ones that caused the suffering. These are full of bitter tears stress hormones . Most people when they feel relieved, because tears, as it were washed away the stress from the body.
Tears of happiness not display unwanted substances from the body, but soften the action of adrenaline, - as well as involuntary tears laughter.
It is useful to whether to cry?
According to experts, people who are not shy to openly express their feelings, suffer less from stresses and easier for them to carry. Therefore, nervous stress is not harmful to let myself go and throw out the accumulated experience in mourning.
Tears were washed out of the body not only harmful hormonal substance, but catecholamine - substances that stimulate stress . Of tears and emotions is dangerous to health, that's why men who are crying 4-5 times less often than women, live on less than 7 years. The habit to drive deep into the experience is fraught with severe disorders of the nervous system, hypertension, gastric ulcer, colitis and cardiovascular diseases.
But while doctors warn that tears bring greater relief only in the case when a man finds a crying emotional understanding and comfort from others.
Why women - crybabies?
Women do cry more often than men. "I'm sorry" in this hormone prolactin Which is responsible not only for the secretion of tears, but also for the production of milk during breastfeeding. Men's reticence is partly due testoterona. This male hormone prevents the accumulation of tear fluid in sufficient quantity.
Partly emotional greed of men is caused by social stereotypes. Which inspires the boys parents? Correctly. "Crying shame you're a man! "
