Have you ever laughed so hard you felt sore? A good belly laugh is almost as good as a good workout. In fact, it is a workout. There is a reason that you will feel sore after you have a good long laugh. Researchers have found that laughing, the physically intense whole body laughing, actually provides you with a mini-workout. This workout is very similar to doing aerobic exercises. Laughing hard will boost your respiratory rate, heart rate, and increase your oxygen consumption. Having a good hard laugh can give you some of the same benefits as a decent workout. However, the exercise benefits of laughing only come when you have periods of really intense laughter. Unfortunately, this means that sitting around watching funny videos is not going to be able to replace your real workouts. Even if laughter cannot replace your workouts, it can provide you with a few of the benefits and a lot more fun.
