The secret to longevity is just one word

Laughter is a special fitness exercise. When a person laughs, the facial expression muscles and the chest and abdominal muscles move. When laughing, even the muscles of the limbs move together, which speeds up blood flow in the body, promotes metabolism throughout the body, and helps improve the body's resistance to disease. French doctors pointed out that laughing out loud is a process of absorbing oxygen. Oxygen enters the blood and promotes blood circulation. It can speed up the elimination of toxins in the blood that cause body function decline, and the sugar, fat and lactic acid in the human body can also be decomposed faster.

Laughter is also an effective digestive aid.

Pleasant emotions can increase the secretion of digestive juices, and joyful laughter can promote the activity of the digestive tract, thereby increasing appetite and helping the digestion and absorption of food.

Laughter is the "guardian angel" of the respiratory system.

Laughter and joy can make people involuntarily take deep breaths, just like doing breathing gymnastics, which helps to expel secretions from the respiratory system.

In addition, laughter can regulate psychological activities, overcome the depression caused by loneliness, and help individuals better adapt to the external environment.

After analyzing the impact of stress on the human body, psychologist Ken Powell pointed out: As soon as laughter comes out, the body will relax instantly because it can inhibit cortisol and adrenaline and eliminate the harm caused by stress. Recently, American doctors pointed out that human laughter is controlled by the prefrontal cortex of the right brain, which is also responsible for human emotions. Every time you laugh, it stimulates the production of multiple functions and hormones, which are very important for maintaining human health. When people laugh, their attention is diverted, their muscles relax, and the secretion of anti-pain hormones increases, which can relieve symptoms such as headaches, back pain, abdominal pain, and muscle pain. A Japanese doctor uses laughter to treat cancer and other diseases - he recorded laughter and beautiful conversations for his patients to listen to, and added beautiful words such as "My body has the ability to overcome the disease" in the middle to improve the patient's immunity through the subconscious. He found that laughter can significantly increase the activity of cancer-killing cells.
