When is the last time you had a good cry? If you can’t remember, then you might be past due. About 85% of women and 73% of men say they feel better after they cry. Tears produced by emotional crying are chemically different from tears caused by pain. In fact, they carry stress hormones that accumulate during emotionally difficult times. This has led researchers to believe that the evolution of tears has more to do with relieving stress than communicating emotions. So the next time you feel the urge, go ahead and cry. You’ll feel better afterward.
