Many mechanisms exist for tears to cleanse the body. Reflex tears remove smoke, dust, and grit from your eyes. How about those bothersome loose eyelashes?
Eye tears lubricate and prevent infection. They sustain tear duct function and keep eyes moist without overflowing.
You might be surprised by the benefits of emotional crying. An emotional reaction with cortisol and other poisons causes tears.
Self-soothing can regulate emotions by activating the parasympathetic nervous system (PNS), which helps your body rest and digest.
A good weep can relieve physical and emotional discomfort. Long-term crying releases oxytocin and endorphins.
After these feel-good chemicals are produced, your body may go numb. When people cuddle, have sex, or bond socially, oxytocin is released. You feel calm or well-being.
Research suggests that crying, especially sobbing, may boost mood and reduce discomfort. Weeping occasionally is actually good for one's mood.
