Crying as adult is often looked upon as weak or embarrassing and seen as someone losing control. But tears have incredible health benefits when we are feeling heavy emotions. Biochemist Dr. William Frey, at the Ramsey Medical Center in Minneapolis, has spent his career studying tears and discovered that emotional tears contain stress hormones that get excreted from the body through crying. After studying the composition of tears, Dr. Frey found that emotional tears shed these hormones and other toxins that accumulate during stress. Additional studies also suggest that crying stimulates the production of endorphins, our body’s natural pain killer and feel-good hormones. Tears are literally your body’s release valve for stress, sadness, grief, anxiety, and frustration. We would all be better off if when we feel the need to cry, not stifle it back but just let it out.
