This should be discussed from the following aspects:

Laughter can enhance immunity. This is because laughter can excite the prefrontal lobe of the brain, and then make the brain secrete hormones, which can enhance Pan Zi, a natural killer cell, and thus improve immunity. Laughter can also make the brain secrete a hormone-β-endorphin, which can produce a sense of Shaanxi, making people optimistic and happy. Laughter helps blood circulation. Laughter can promote the movement of respiratory muscles such as diaphragm and intercostal muscle, accelerate the blood circulation of abdominal organs, help purify blood and enhance the function of important organs such as heart. Laughter can also raise body temperature and help strengthen the function of immune cells. Elevated body temperature can also promote the burning of toxins such as triglycerides and uric acid, and prevent lifestyle diseases. Elevated body temperature can promote blood circulation in the liver, gastrointestinal tract and lungs and keep these organs healthy. People advocate laughter, not only because it is a pleasant and comfortable expression that is willing to be accepted by others, but also because it is beneficial to people's physical and mental health.

Laughter affects diaphragm vibration and abdominal muscle contraction, which can push and massage internal organs, accelerate venous and lymphatic reflux, thus reducing the burden on the heart. When laughing, abdominal breathing can improve the function of respiratory muscles and increase people's vital capacity.

Laughter can affect the movement of 13 facial muscles in different degrees, which directly helps to promote facial blood circulation and keep beauty. Laughter also helps to eliminate nervous tension and relax muscles, make people forget troubles and fatigue, and improve their appetite and sleep.

Russian experts believe that laughter is a pleasant reaction, which acts as a "safety valve" and has a good impact on people's mental health and physical health.

Japanese scholar Hiroshi Chong, after visiting the long-lived elderly in India, concluded that laughter contributes to longevity.
