Crying actually improves your mood
A recent Netherlands study showed participants really sad movies and then noted who cried and who didn’t. Those who didn’t felt no different emotionally after the movie, while the criers felt worse. However, within 20 minutes, the criers returned to pre-movie levels, and after 90 minutes, the criers felt much better than their stoic counterparts. “This pattern is often found in retrospective studies where people are asked to rate their mood levels after having experienced a good cry,” said lead author Asmir Gracanin of the University of Tilburg in the Netherlands.
Crying helps relieve stress
William H. Frey II, Ph.D., a biochemist and director of the Psychiatry Research Laboratories at the St. Paul-Ramsey Medical Centre, Professor and Director Alzheimer’s Research Center Regions Hospital Foundation, Minnesota, also made his study participants cry by showing sad movies. (Brian’s Song was a biggie.) His theory was that we feel better after crying because it removes chemicals that build up during stress. “We don’t know what those chemicals are, but we do know that tears contain ACTH, which is known to be increased in stress. We don’t know if they are increased in tears,” reports Dr. Frey.
Frey continues, “It’s important that we evolved this ability. If you can alleviate stress, you can prevent stress damage to the heart and brain, and improve long-term survival. We shouldn’t be conditioning young children not to cry; we should be happy that they have the ability.”
Tears cleanse and protect the eye
Non-emotional crying has health benefits, too. You know how you tear up when you’re chopping onions? A chemical from the onion is released, hits the surface of the eye, and creates sulphuric acid. In order to get rid of it, your tear glands produce a lot of tears to wash the chemical out of the eye. Tears also contain lysozyme, which is both antibacterial and antiviral, and glucose, which nourishes the cells on the surface of the eye and inside the eyelids.
Tears also help our nose
Tears travel internally through the tear duct to the nasal passages, where they encounter mucus. When enough tears mix with the mucus, it loosens and is shed, keeping the nose moist and bacteria free, says psychiatrist Judith Orloff, MD, author ofEmotional Freedom.
