Do you know why we cry?

Prof. Know Why explains:

Women cry 64 times a year on average, while men just 17, says a recent study. Actors and politicians do it on demand though! But why does crying happen in the first place?

When we become upset, our brains and bodies overreact and work overtime, producing chemicals and hormones. Crying helps eliminate t,hese extra chemicals that we don't need, in the form of tears. These tears are formed in tiny glands present in the upper eyelids of our eyes, called lachrymal glands.

Scientifically, emotional tears contain high levels of manganese and a chemical called prolactin.

As our tears flow, they sooth our sadness or distress by disposing of these chemical agents. That is why generally, we feel calmer or more refreshed after crying, because the tears get rid of these hormones that are produced when we are sad, happy, or distressed.
