China's methods of preserving health, improving intelligence, qigong music and nourishing qi are deceptive. Eating well, sleeping well and exercising well are the best ways to keep healthy. The methods of health preservation include diet conditioning, exercise health care, acupoint massage and so on. Diet conditioning: You can choose a suitable diet according to your body's TCM constitution. For example, people with yin deficiency can eat more nourishing foods such as sea cucumber and tremella, while people with yang deficiency can eat foods such as mutton and walnuts that tonify spleen yang and warm kidney yang. People with phlegm-dampness constitution are suitable to eat more foods that strengthen the spleen and help transport, eliminate dampness and resolve phlegm. Exercise health care: We should develop good exercise and fitness habits at ordinary times. You can do more aerobic exercise, such as walking and jogging, or you can play Tai Ji Chuan and Baduanjin.
