Can Laughter Lower Blood Glucose? By Trisha Porretti

We have heard from the Bible to Reader’s Digest that laughter is good medicine1.  Diverse literature suggests that laughter and a good sense of humor can be beneficial to our health and well-being.2    It is popularly believed, but difficult to empirically prove, that laughter can decrease stress, reduce anxiety, discharge tension, and increase self-esteem. 3  We do know that laughter can lead to immediate increases in heart rate, respiratory rate, respiratory depth and oxygen consumption, followed by a period of muscle relaxation, with a corresponding decrease in heart rate, respiratory rate and blood pressure.4   In lay terms, this is very similar to the positive effects of exercise.
