cry

The following are some facts that I found from Wikipedia, quite interesting and useful too. When encounter of emotions, don’t hold your feeling, crying it out and you’ll feel better then move forward for a better life waiting for you ahead.

 

There are three types of tears: basal tears, reflexive tears, and psych tears.

 

Basal tears are produced at a rate of about 1 to 2 microliters a minute, and are made in order to keep the eye lubricated and smooth out irregularities in the cornea.

 

Reflexive tears are tears that are made in response to irritants to the eye, such as when chopping onions or getting poked in the eye.

 

Psych tears are produced by the lacrimal system and are the tears expelled during emotional states. Tears produced during emotional crying have a chemical composition which differs from other types of tears. They contain significantly greater quantities of the hormones prolactin, adrenocorticotropic hormone, Leu-enkephalin, and the elements potassium and manganese.

 

A theory that crying is a mechanism developed in humans to dispose of this stress hormone when levels grow too high.
