As humans we laugh and cry, but seldom do we question how, or why. There are many processes involved in both responses. Cultures around the world allow both crying and laughing as acceptable behaviors. With crying, as well as laughter, the body goes through physical or chemical changes. Crying and laughter are beneficial to us both emotionally and physically. We must have them to function in the world.
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. The third kind of tear is 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.
How then actually do we cry? The psychic tears (or emotional tears) require an emotional response, or trigger to be activated. This response can be caused by an outside source, either pain or loss of love, etc., or from an inside source (self-realization of one's life and others). When emotions affect us, the nervous system stimulates the cranial nerve, in the brain and this sends signals to the neurotransmitters to the tear glands. Thus, we cry .The largest tear gland, the lacrimal gland produces the tears of emotion and reflex. Many believe that the body, in times of emotional stress, depends on this gland to release excess amounts of chemicals and hormones, returning it to a stable state.
There are many culturally acceptable reasons to cry in society .The first accepted reason to cry is probably death. Grieving includes crying and often times it was believed that if someone did not cry, they would suffer physically because they did not release their pain. Experiences in life and love are other reasons society allows us to cry. Women have been allowed to cry more than men traditionally, but the benefits of crying seem to suggest that men need to cry more. Cultures around the world have crying out of obligation, for show, and for grief and pain. Each culture defines where and when it is acceptable to cry. Cultures, in some parts of the world, sometimes determine the length of crying and mourning. hope this helped!!

Yes. Just got done, actually. My best friend since the age of 4 (I'm 20 now) died in September in a car crash. This will be the first Christmas in 16 years that we have not been together. I love and miss her soooo much. Been crying about it all afternoon until about 10 minutes ago.

lachrimation and tearing are carthatic as well as medical/medicinal functions. the body and brain learns that when you tar up, you feel better so apart from tearing up to clean the eyeballs of foreign matter, feel good hormones or endorphins are released when you tear up and the body adopts that as a defense to stress in scertain situations to ease the stress or make you feel better

Tears are a liquid produced by the body's process of lacrimation to clean and lubricate the eyes. The word lacrimation may also be used in a medical or literary sense to refer to crying.

It's a trigger in our mind, see we get sad, and our thoguhts become over wheleming, if you notice we don't blink as much and our mind is focused on other things, it causes tears.
