I don't know who said this, but it fully embodies the wisdom of China people, and also shows that in ancient China, we also had a full understanding of psychology. Make your heart stronger: People who are humorous and like to talk and laugh with others have a lower risk of cardiovascular disease. Because laughter can make blood circulation better, blood circulation can avoid the accumulation of harmful substances, thus reducing the threat to blood vessels and reducing the chance of heart disease.
Enhance immunity: laughter can increase white blood cells in the body, promote antibody circulation in the body, enhance immunity and fight germs. In addition, laughter also helps blood circulation, accelerates metabolism, and gives people a feeling of vitality. A good mood is the guarantee of good health. A friend told me that 70% of the people who died were angry and 20% died of something. Only 10% people died of natural causes. Therefore, we should keep an optimistic attitude and adjust negative emotions in time.
It is said that "laughter" is the best medicine, but no one can put forward specific theoretical basis. Now, a Japanese geneticist is cracking the mystery of laughter: he thinks that laughter can activate some genes in people. People usually think that genes are immutable, but in fact, 90% of genes are dormant or inactive to produce protein, and these dormant genes can be awakened by some form of stimulus. Laughter corresponds to the five elements of fire and the heart in the five internal organs. Face to face is born of mind, mind is born of ritual fire, yang fire accumulates enough, yang fire produces yang soil, and spleen and stomach return to soil, which is the foundation of the day after tomorrow, maintaining other viscera and helping the five elements and five zang-organs in the body to produce grams normally. So smile often, stay healthy and stay young forever.
