As in the evolutionary reason for crying?

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.
The psychic 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.

No one seems to focus on the evolutionary reason. I would guess that...
Animals need to avoid dying when in confrontation. To do this they either run or fight. Theres a lot of evidence to suggest that stronger creaters survive longer, breed more thus their children are stronger etc.
You could use the same argument for avoiding fights. If you can convey to the aggressor that you are beaten (shoulders down, wailings, shaking, wetting yourself, and crying) you will survive, have more children than those that got killed and your children will be better at showing they are beaten.
Therefore- crying sends out a message that you are weaker, beaten etc.
Those who can show they are beaten are less likely to be killed by an attacker
As people survive by using the crying mechanism the gene gets stronger and more prevelant.
Sounds a bit fishy to me. What do you think?

Crying is an emotion like laughter and anger and jealousy. I have a few good cries a week because I miss my father so much. I have excepted his death but that doesn't make it any easier to deal with the loss. After a good cry I feel better. Just like when I do Taebo I feel better. That is a freaking GREAT anger management program, or rather exercise. Then I know I won't beat the crap out of anyone who pisses me off.

no longer quite agreeing with you there yet i think of that some people cry far too often on the stupidest issues, confident often for interest. yet they get the incorrect variety from me : D i'm truly attracted to why we cry nevertheless, like what develop into the evolutionary ingredient of it? and why crying precisely? im tremendously optimistic, in an evolutionary way of conversing, water understanding of your eyes, hitching sobs, and a runny nostril dont truly acheive plenty.

i am no scientist, but i think since we (humans) are lot more evolved than the aminal in sense that we can feel emotions, sympathy and other feeling due to the social conditioning and way of life, we have hormones produced in our body that are probably not in other animals. When we have an immense feeling of pain or pleasure our body produces the hormones in vast amounts. The only way to get this hormones out of our body is through a duct in eye (i.e. crying). That is why when you experience overwhelming emotion (be it pain or pleasure) your body gets rid of that chemicals from your body through crying.
It is similar to other ways of body getting rid of waste from body (which is why tears taste salty, like p i s s, lol)
Hope this was helpful.

aswell as releasing toxins from the body as other posters have stated, crying is a cathartic safety valve. when am angry, i sob my heart out rather than resort to violence, and yes, i feel calmed afterwards.
an evolutionary aspect could be linked to the release of toxins as a build up could cause stress to the body resulting in illness/desease such as cancer, mental ill health, heart disease. it's better out than in.

It requires lots of energy, and releases endorphins which make you feel better.
I knew a couple of girls that use to cry just to pull. Stupid, but it worked for them i suppose.

Crying is a form of emotion and it is not healthy for you or normal for anyone not to show emotion. Our Heavenly Father cried and even repented that He ever created man. It is just a way of expressing yourself with out using words or when you can't say anything. Crying is not always a form of showing sorrow but joy. Its something that God created us to do

After you've had a really good cry it always makes you feel better.
