Obviously crying is the result of feeling strong emotions. But is there a physical/biological reason for it? What is the purpose of tears and wet eyes?
Actually when we cry we release certain types of chemicals and endorphins which make us feel good. Kinda like your body is saying hey you're sad, this will cheer you up.
Yeah I think there was research that sad tears had increased stress hormones in them, making them a stress reliever as well... But honestly I'm only just going off my memory
