how does our body know how to cry?

Question

i know how tears are created, i know we learn to cry emotionaly by repetiton because we saw others do it. But how, from seeing them, to being in an emotional place do we also produce tears, without wanting it, because it is not like we command tears, they just come...how?

Answer 1

Actually, there is an article in a recent Scientific American that talks about just this subject.
At some point in the evolutionary process our tear ducts were wired to our emotional centers in our brain.
According to the article, we are the only animal that is wired like this.

Answer 2

We process things through pain and pleasure. A good example would be although drugs and cigarettes are bad for your health, alot of people who tend to be addicted to it was because it was connected to pleasure. In the begining the pleasure was because they were noticed by the social gorup they wanted to be apart of , and then after a while there was more reasons to want that drug.

Food is another example, you cant eat worms, because you connect it to pain ( its a moving creature, and we are used to cook non moving creature and no insects), that is what was taught to us, what is bad and what is good. Therfore we assosicate that with pain. All this is in your mind, now if you force yourself to eat it, the first few times it would be the worst thing ever, but after awhile because you have to repeat the whole process again, you push your brain to change it to pleasure, so therefore later on you might think worms are actually the best dish out there.

Now this is the same thing with crying, babies cry, they start smiling few months later, but when a baby is hungry or in pain they naturally scream and cry, which means the brain associates cry to pain.
When you grow up, within your social group it is indirectly or directly taught to you for what you cry and for what you should be happy. For instance when someone passes away, everyone starts crying as a id you just wath and wonder why everyone is crying, when you find ou thtat someone has passed away it still doesnt bother you, because its not of a relation to you , but now in our world today , being diverse nad understanding is one of the main keys to communicate within our social group, so what we have learnt is to put ourselves in that other persons shoe. So it looks like you had someone passing away , which is related to pain , because you think about not seeing them, not communicating with them ever again which is huge pain. Therfore your brain can sense this and you start to cry.

Physical body reaction does that too. When your heart is pounding because someone scares you , then you cry = pain

when someone hits you painfully, you cry = pain

Answer 3

Tears are a reaction to strong emotions. Our body acknowledges that when we see or feel something that produces those emotions inside and we cry.

Answer 4

Because the body knows what's best. We are made up of atoms and molecules that are ancient, and are absolute living intelligence! This is the same way it knows to plug up a cut so we don't bleed to death. You don't will your body to scab over & heal, it does this automatically... isn't that awesome? Keep on wondering at marvelous things you observe, it'll keep your mind sharp and your spirit young. Peace!

Answer 5

Crying is one of the body's natural defenses for flushing out toxins that build up (yes, our bodies create toxins--score one for those who believe that our bodies are against ourselves). When you are sad or happy to tears, it is because your body is trying to get rid of those toxins. And that is the answer to why those who hold back tears have health problems.

Another one of those bodily misteries. Why question it. It just happens. I mean next are you gonna ask " Why do we get wet when we're turned on?" ??

Answer 7

I think it's just an automatic reaction from our brains we learned by evolution and such...
