Emotional tears contain higher levels of certain stress hormones such as adrenocorticotropic hormone and prolactin, whose levels rise with stress. In some ways then, when you cry, you cry out your stress.
Also: fake tears don’t work.
The eye produces an average of 15–30 gallons of tears each year. As we age, we produce fewer tears. An absence of tears can be damaging to your eyes.
Tears are essential to eye health. They help the eye stay hydrated and offer protection from bacteria, dust, dirt, and other irritants.
Once considered “purposeless”, tears are now recognized as an essential aspect of our physical and emotional health.
Researchers have proposed that emotional tears originated from animal vocalizations. Babies’ lacrimal glands are not fully developed at birth and can’t produce tears, but they still need to be able to signal when they’re in distress or need care, so they vocalize.
Crying provides many benefits. Not only is it a signal for help during physical and emotional distress, but crying can also help relieve stress, decreasing the levels of cortisol in the body.
