For many people crying - a natural thing.We know how the birth cry aloud.So, according to experts, it shows itself a process of natural selection.On the crying child's mother simply can not pay attention.The ability to shed tears evident in children aged 4-6 weeks, that is, a person learns to cry before laughing.At the same time we - the only beings capable of consciously let a tear.For animals this is purely reflex process.Why do people cry?
Nature has provided us with tear ducts to quickly and safely clean the surface of the eye from pollution, noise or pain.So before you find out why people are crying for no reason, it is better to clarify if they did not get the mote in the eye - sometimes it's a good reason for the violent tears.But this is quite animal instincts - to clean the eyes may cry almost all warm-blooded creatures.
exact same answer to the question why a person cries, from the perspective of the psychophysiological expediency, science can not yet provide.Biochemist W. Frey conducted research, during which revealed a relationship between "stressogonnostyu 'tears and the amount of protein in their composition.It was found that the more a man cried from the stress, the greater the amount of protein contained in its tear fluid.What this mechanism was conceived by nature, the scientist could not answer, but suggested that the body takes in tears for him some unwanted substances generated by stress.
But certainly know why people cry, from the point of view of psychology, - tears are the most effective way to relieve increased pressure and get rid of traumatic soul factors.Therefore, by the way, most often characterized by tearfulness women as being more flexible and sensitive nervous system.By the way, according to research by Dutch scientists, the greatest love for the "wet case" characterized by the fair sex from Chile - they cry more often than other women of the world.They were followed by American, Turkish women themselves Dutch.And from the men of the leaders in the tears are the representatives of the American nation, but the Chinese did not cry at all.
Another speculation about why people cry, shared Israelis.According to scientists there the tears signal environment, the psychological and the physical protection of a person at this point is not included in full force, which means that it is vulnerable.And what if the people crying?That's right, defend it.In favor of this theory says that when a baby crying at his parents and adults just triggered a reflex desire to defend and protect him from all harm.
But in general, whatever the reason for the tears, the most important thing that they - an indispensable tool to rid the body of excess, whether it's a simple eyewinker or a whole heap of oppressive problems.So cry quite shameful, because that way you just get rid of unnecessary in the body - physically or spiritually.
