Have you ever cried at a wedding or while watching a touching reunion? You're not alone - 85% of people report crying from positive emotions according to Yale research.
These "tears of joy" serve an evolutionary purpose. Neuroscientists found they help regulate overwhelming emotions by activating the parasympathetic nervous system. The act of crying releases oxytocin and endorphins that actually make us feel better.
As Italian researcher Dr. Oriana Aragon notes: "People who cry from happiness recover from strong emotions faster than those who don't." So next time you tear up at a beautiful moment, embrace it - your brain knows what it's doing.
