Why do we cry Ill tell you what I know or think I know: that the body does not distinguish between emotional and physical pain; the muscles around the lachrymal glands of the eye receive a message from the brain, then tighten and squeeze out tears. Tears contain high levels of the hormone ACTH and prolactin, endorphins (which we know are mood-altering and pain-killing). Prolactin in humans controls fluid balance; by the age of eighteen women have 60 percent more prolactin than men, which may explain why women seem to cry more often. Nonscientific version: unhappiness cant stick in a persons soul when its slick with tears.
