Crying is a more complicated process than one would at first imagine. First of all, there are really three different types of tears. BASAL TEARS keep our eyes lubricated constantly. REFLEX TEARS are produced when our eyes get irritated, like with onions or when something gets into our eyes. PSYCHIC TEARS are produced when the body reacts emotionally to something. Each type of tear contains different amounts of chemical proteins and hormones. Scientists have discovered that the emotional tears contain higher levels of manganese and the hormone prolactin, and this contributes in a reduction of both of these in the body; thus helping to keep depression away. Many people have found that crying actually calms them after being upset, and this is in part due to the chemicals and hormones that are released in the tears.
