Laughter also has the ability to balance the levels of oxygen and carbon dioxide in the body through the process of deep diaphragmatic breathing which flushes the lungs of stale residual air and replaces it with fresh oxygen. This energizes and recharges the body mechanism for peak performance thereby reinstating good health.
