When the famous British chemist Faraday was young, he suffered from mental disorders due to excessive work stress, and often suffered from headaches and insomnia. Despite long-term drug treatment, there was no improvement. Later, a famous doctor examined him carefully, but did not prescribe any medicine. Before leaving, he just smiled and said a British proverb: "A clown in town is worth a dozen doctors." Then he left. Faraday pondered over these words and finally realized the secret. From then on, Faraday often took time to watch farces, circuses and comedies, and often laughed with joy. Such a happy mood greatly improved his health, and his headaches and insomnia were cured without any medicine.

According to reports, a German physiologist introduced the secret of longevity to people on his 92nd birthday in just one word: "laughter."

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.

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.

It can relieve symptoms such as headache, back pain, abdominal pain, muscle pain, etc. 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.
