Is there a purpose?
In: Biology
You will usually find after a good cry, you tend to feel better. That’s because it’s a reflex of self-soothing that releases endorphins that chemically makes your brain calmer, lessens pain and makes you feel better overall.
Someone has already mentioned the small dose palliatives in tears, but that’s only part of the answer. Crying comes before language, and is a way for infants to communicate that they need something.
Aside from the answer given the other “biological” (I deem this as why evolution made it that way) is because it expresses sadness without any form of language. Like all of our muscles that allow us to make facial expressions tears help convey emtoions, which is incredibly useful for our species which has evolved with social ability in mind.
Tears contain tiny amounts of a very powerful pain-killing compound. It’s literally an act of self-soothing. Very useful for an organism with emotions that can go haywire.
