Laughter is Medicine for the Immune System
In order to understand the connection between laughter and the immune system, you must be aware of the lymphatic system. It is basically the backbone of the immune system that continually collects waste from all parts of the body deposited in the tissues through blood capillaries. The system then cleans the fluid and transfers it back into the circulating blood at your neck.
Contrary to our circulatory system that has a heart that pumps the blood in an ongoing circle throughout the body, the Lymphatic system is a simple transport system devoid of the pump. Studies suggest that laughter facilitates diaphragmatic breathing, which is essential to create intense pressure inside the thoracic duct. During such time, the lymphatic fluid moves to the area with lesser pressure, transferring the lymph through the vessels and increasing the flow and speed.
