Belly Laughs Are Good for You

Can laughter really boost your immune system? Results of some studies suggest it can. In a study of healthy males, watching a funny movie boosted natural killer cell activity while watching an emotionally neutral movie did not boost immune system function. While more research is necessary to establish a conclusive link between laughter and improved immunity, go ahead and have a good chuckle. Belly laughs feel great. They can't hurt and they might help boost your immune system and reduce the likelihood of illness.
