Why do we cry when we are overwhelmed with joy?
Answer:
This remains one of the greatest psychological and biological mysteries. Scientist can't seem to figure out why overwhelming emotions like great joy or grief, or frustration or anger or terror, drives as to tears, since the lacrymal glands, the glands that produce tears, where originally meant to simply lubricate our eyes. Crying was also supposed to be a defense for the eyes to wash away dust particles, insects or other objects that can harm the eyes. But why we cry when we feel overwhelmed with an emotion? There is still no definite answer. But the latest research seem to show that in our tears, which is 98% water, contains hormones which are associated with the emotions, along with anti-oxidants, anti-bodies and other helpful enzymes. What these researches seem to show is that crying, in facts, is healthy psychologically and biologically.
they are called tears of joy..because something good happened!
i think that tears are one of the most powerful insights you have to offer, only when someone is on extremes do they cry... when you are overwhelmed with such emotions you let them out with tears
you have to think not only do we cry when extremely happy and depressed, but we cry when we are overwhelmed with laughter and other things like that.
what a great feeling isn't it.
it is necessary for our body to take out our feelings and emotions.So when we are full of joy or sorrow, we cry and speak out to share with outside world.
Great question. We are the only animal that actually cries in association with emotions. Not even our closest relatives, the great apes actually shed tears. So why we even cry at all is another good question.
I think it is much like facial expressions. We are wired to communicate to other minds around us how we are feeling. Lots of animals have tear ducts, but they are not wired in association with deep emotion. We are the species with by far the most communication about the details of how we are feeling. Because of our huge brains we are helpless as infants longer than any other animal. As a result attaching to our parents is way more important than it is for other animals that can fend for themselves, or at least walk shortly after birth. Attachment helped keep infants from being easy prey for preditors that found them delicious high calorie treats.
Facial expressions about deep emotions are about attachment. It seems reasonable to suppose that our signaling our deep feelings with tears is all part of this.
There is a lot more detail about how some of our ancestors would try to fake emotion to get resources, cheating. Tears would be a definite signal that would tend to show the authenticity of emotion whether sadness or joy.
When we feel emotions, these get into the limbic system, which is in the central part of the brain. Extreme emotions stimulate the limbic system to effect an electrical charge in the hypothalamus, which then produces acetylcholine which is transferred by blood to the nicotinic and mucotinic receptors located in the lacrimal glands in order to produce tears.
THe reason why we cry in times of pain and sadness, as well as in joy, is that the amygdala (part of the limbic sytem) does not distinguish the electrical stimulkations of the various extreme emotions we feel, so whether we feel bad or good, it is simply translated into a simple electric impulse which then forces the hypothalamus to secrete acetylcholine.
