Crying or tearing, is known scientifically as lacrimation. Although most land mammals have a lacrimation system to keep their eyes moist, humans are the only animal generally accepted to cry emotional tears when they are sad or experience other forms of emotional stress. Crying is a natural adaptive response to emotional stress.

Tears flow from our eyes when we cry because they contain chemicals and hormones produced by our bodies.

Tears brought about by emotions have a different chemical make up than those for lubrication; emotional tears contain more of the protein-based hormones prolactin, adrenocorticotropic hormone, and leucine enkephalin (a natural painkiller) than basal or reflex tears.

The limbic system is involved in production of basic emotional drives, such as anger, fear, etc. The limbic system, specifically the hypothalamus, also has a degree of control over the autonomic system. The parasympathetic branch of the autonomic system controls the lacrimal glands via the neurotransmitter acetylcholine through both the nicotinic and muscarinic receptors. When these receptors are activated, the lacrimal gland is stimulated to produce tears.

When we become upset, our brains and bodies overreact and work overtime by producing chemicals and hormones.

Crying helps eliminate these extra chemicals that we don't need.

That emotional tears contain very high amounts of:

Prolactin: a hormone that causes relaxation;
 
Adrenocorticotropic: another — hard to say — hormone that reduces the feeling of stress;

Leucine enkephalin: a very powerful natural pain killer.

(And reflex tears, caused by for example: dust getting into your eyes, do not contain very high amounts of these chemicals at all.)

In addition, crying can act as a very powerful body language signal that another human is in need of help and support.

The chemicals and hormones disappear from our body through the form of tears. As our tears flow, they sooth our sadness or distress by withdrawing these chemical agents.

That is why many people 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.

All this suggests that emotions have a much closer relation to thought - and a much looser relation to states of the body - than Damasio will admit. For thought is also characterized by its intentionality, by its property of being "about" something. States of the body, on the other hand, is incapable of being "about" anything. The more sophisticated the emotion, the closer its relation to thought.
 
Admiration, for example, is inextricably bound up with the thought that a particular thing or person is admirable.

This is why we cannot attribute admiration (or, indeed, contempt, gratitude or amusement) to animals. But we have no difficulty attributing the more primitive emotions of anger and fear to animals, because these emotions don't necessarily imply any corresponding thoughts.

Types of tears:

Our tears glands may release fluid (tears) if we are:

1. Sad, emotional or cry. In some cases they may come out when we are extremely happy.
2. Basal tears protect our eyes by keeping them most.
3. We may also get tears if something irritating goes inside our eyes and tears try to flush it out.

There are some benefits of crying:


The action of crying itself releases stress relieving hormones which make us feel better. That also kind of explains why people feel more calm and refreshed after shedding some tears. Crying opens the lungs, cleans & exercises the eyes and softens the temper. Crying releases emotional tensions and has a beneficial effect on both the mind and emotional tensions and has a beneficial effect on both the mind and body. Females do seem to produce psychic tears more frequently than men possibly due to habits and a greater level of emotions. Crying is perhaps the easiest and fastest way to release emotional pain.

Animals also cry:

Some animals appear to cry because of emotional reasons, most prominent being elephants. They are even mourn the dead. Many animals can produce tears when sufferings in pain like cats, dogs, cows and goats.

It is an emotion that was given to us by God. When we cry it completes the emotion. Crying is a release. If someone you love dies and you are sad but don't cry, then you may feel as though something is wrong and is missing in you. A tender heart means the person will have sympathy for others who experience grief. Like laughter is contagious, so is crying.
