Is there a purpose?
In: Biology
Tears provide a visible signal that you are in pain, that can be silent.
EG, you’re hunting a sabretooth tiger with your caveman buddies, and you hurt yourself. The other cavemen see your tears and know you’re hurt, you didn’t have to make a sound which could be heard by the sabretooth tiger.
The stuff that deals with pain don’t really distinguish between physical pain and emotional pain.
So that’s why your body goes through a bunch of physical responses to emotional pain when you are sad, including crying.
