Did you know that we shed different types of tears based on our emotions?

Each tear type is composed of unique chemicals — mainly salt, water, and lysozyme — that give them their variable structure.

Emotional tears contain a natural painkiller

According to scientist Claire Phillips, tears of grief contain the neurotransmitter leucine enkephalin which helps relieve the body in times of stress. In such a way, our tear ducts can act as a natural painkiller.

There’s a biological and evolutionary reason we feel better shedding tears after experiencing a traumatic event.
