Why do we cry when we are upset?

Question

It seems like an odd biological response, don't you think? I think tear ducts were created to clean the dirt out of your eyes, so why do we cry when we are upset or angry?

Answer 1

There are three basic types of tears:

1:Basal tears: In healthy mammalian eyes, the cornea is continually kept wet and nourished by basal tears. They lubricate the eye and help to keep it clear of dust. Tear fluid contains water, mucin, lipids, lysozyme, lactoferrin, lipocalin, lacritin, immunoglobulins, glucose, urea, sodium, and potassium. Some of the substances in lacrimal fluid fight against bacterial infection as a part of the immune system.

2:Reflex tears: The second type of tears results from irritation to the eye by foreign particles, or substances such as onion vapors or tear gas or pepper spray. These reflex tears attempt to wash out irritants that may have come into contact with the eye.

3:Crying or weeping: The third category, generally referred to as crying or weeping, is increased lacrimation due to strong emotional stress or physical pain. This practice is not restricted to negative emotions; many people have been known to cry when extremely happy. In humans, emotional tears can be accompanied by reddening of the face and sobbing — cough-like, convulsive breathing, sometimes involving spasms of the whole upper body. Tears brought about by emotions have a different chemical make up than those for lubrication.

Humans have various response mechanisms to cope with various situations - stress, pain, shock. We cry when we are upset because the bad feelings in the mind cause a reaction in the body - we either cry as a result of physical trauma (getting dust in our eyes, chopping onions!) or because we are upset.

Whether this is a natural, inbuilt response, or is learnt is a matter of debate. It could be that, as babies and children, we cry when we are uncomfortable, but we soon realise that we get a response to anything if we cry - so we learn to cry to get sympathy, and it becomes semi automatic. Or it could be in built - our central nervous systems' way of dealing with any form of upset.

It is similar to shaking when we are frightened (though that serves a purpose in that it causes us to be more responsive), freezing when we are terrified (quick! Play dead!), going red when we are embarresed, going tense when we are angry, or going into shock after great trauma.

It could be that we cry to get rid of some chemicals in the body (see link below) - but I don't really fully agree with that personally....

Answer 3

It is just one of the ways the nervous system can regulate itself. We we get "upset" the autonomic nervous system is activated and part of that activation includes the tear ducts (and other glands, like sweat and salivary).

Answer 4

No, i do not evaluate it develop into once stupid in any respect. That historic goldfish develop right into a properly-conventional chum to you. i wager you knew his little quirks and conduct and felt some attachment to him. laying off the goldfish develop into like dropping a pal and it is fairly everyday to grieve after we lose friends. i have a freshwater aquarium at position of residing. besides the actual incontrovertible reality that i can't say i have been as linked to my scaled friends as my hairy friends, I even if experience horribly at the same time as considered one among them dies. I had a pair of fish merely many years in the previous that the position the merely genuine voters of my tank on the time. A male and woman. they were very historic for fish. in the top the male died. the female with suggestions from no skill moved from the spot the position we eliminated the lifeless male. She died some days later. i trust she died of a damaged heart :(. So, you spot, fish are better than a eye-catching element that swims round for our entertainment. they're residing issues and it is alright to grieve once they bypass.

Answer 5

weeping when something gets in your eye is a reflex response by the body but if u say cry, then that's a personal choice as it can be voluntarily controlled by the brain.

Answer 6

Like everything there it is a case of cause and effect, there must be an initial cause to produce the effect... No sadness no tears etc...
Dealing with the cause deals with the tears...

Answer 7

Answer 8

Yes, it is one of the my weak point for me , it because it upset second every body is in force and cry is best way for be calm i think..

Answer 9

....a side effect of crying is production of a hormone that makes us feel good, hence "have a good cry, you'll feel better" So it is more healthy to snivel & dribble, not only cleans out youe eyes but is good for the soul!!

Answer 10

there is a really weird belief that crying expels the poison inside you. they say when you get upset or when you feel bad your body creates something bad, and crying is the way to expel it.

it reality, its just human response.
