Laughing Health Benefits

According to a study in the INternational Journal of Obesity, laughing out loud can help you burn more calories. For 90 minutes 45 people watched videos that were funny (Austin Powers) or big snooze fests (a show about the English countryside) while scientists measured their heart rate and calorie burn. Laughing out loud increased both numbers by up to 20% compared with watching quietly. So giggle for 15 minutes a day could burn as many as 50 calories.
