tired of exercising?Try Laughing
running vs. laughing? so what’s the competition about? studies at the University of Maryland’s Center for Cardiology have found that laughter can be as effective as going for a run in terms of maintaining healthy blood vessels.
laughter causes the endothelium - which forms the inner lining of the blood vessels - to dilate, thus increasing the blood flow in the same way as an aerobic exercise.
the study recruited 20 young and healthy volunteers who watched 15 minute clips of distressing scenes from films, as well as clips from comedies. they found that blood flow in the brachial artery in the arm of the volunteers decreased in 14 of the 20 participants, but increased in 19 out of the 20 participants after the funny clips.
