Did you know that laughing hard for just 20 seconds doubles your heart rate for about a minute afterward? According to a research at Stanford University in California, that is the same result one gets from 15 minutes on a stationary bicycle or 10 minutes of strenuous rowing (though you won’t burn as many calories).
Laughter can be an effective mini workout. Laughing not only exercises the heart and lungs, but also provides the same effect to the muscles in the chest, abdomen, shoulders, neck, face and scalp as well. So go ahead, keep laughing! Oh, did I just make you laugh? So now you know it pays to have fun and break in laughter every time.
