When we laugh, we blow the stale air out of our lungs and increase the oxygen levels in our bodies. Our hearts beat faster during laughter and then slow down once the laughter is over. Many of the muscles in our bodies contract when we laugh, and afterward, they relax. It is hard to feel pain or tension when laughing. A positive emotional state can boost the immune system.
Laughter is a way to cope with stress, reduce anxiety, and combat pressure, worry, and frustration.
It can reduce inhibitions and lead to improved interpersonal relationships. It can decrease irritability and lighten a mood. All in all, laughter leads to an improved sense of well-being. Laughter does not substitute for proven medical therapy for disease, but joy and mirth benefit us all immeasurably. Always consult your own doctor about any opinions or recommendations with respect to your symptoms or medical condition.
