In our daily health care life, the most important thing is to pay attention to three balances, namely, nutritional balance, dynamic balance and psychological balance. Everything is measured, and enough is enough. This refers to relative balance rather than absolute balance. The last article said that everyone is an independent individual in their own health care life, and various factors make them different. But the general principle we should grasp is relative balance. The health of life lies in balance, which is more suitable for the theory of TCM health preservation. Let's talk about the so-called psychological balance, that is, we should always maintain a good mood and a good mood in our daily life, and try our best to be comfortable with the ups and downs of life, such as fame, gains and losses. Even if there are factors such as sadness and fear, we should adjust them in a short time through various methods. Many friends' sub-health is caused by psychological agitation, and 60% of diseases are also caused by psychological and spiritual factors. Moreover, due to fierce competition, great pressure, rapid job changes, uncertain environment and many other reasons in modern society, coupled with complicated family affairs and complicated interpersonal relationships, people's psychological state is often in a state of stress and tension, and their minds are exhausted. Improving one's comprehensive quality, keeping cheerful personality, optimistic, open-minded and peaceful mind, and correcting the emerging psychological imbalance in time are one of the most important secrets of health and longevity. Next, let's talk about the nutritional balance in the diet. What is needed in this respect is a reasonable diet, cleanliness and comprehensive nutrition. Of course, due to individual differences, it is very important to choose the diet that suits you best. However, some principles can still be discussed here, such as reducing the number of times of eating out as much as possible in daily life, and choosing a clean and hygienic place to eat even if it is really necessary to eat out for various needs. Try to stay away from all kinds of seemingly "beautiful" food. Beauty here refers to being out of the natural state of food itself. For example, some tremella are whiter than snow, and most of them are vulcanized. In addition, don't be picky about food in personal eating habits. Many MM have this habit. We should eat a comprehensive and balanced nutrition. Picky food is a big no-no. Finally, talk about the problem of dynamic and static balance. I have talked many times about the concept of "keeping healthy by moving, keeping healthy by quieting". For middle-aged and elderly friends, the best exercise is walking fast, and it is not bad to insist on swimming if conditions permit. Besides, playing Tai Ji Chuan, doing yoga and running are also good exercise methods. Meditation with eyes closed can make people relax, clear their heads, enhance their memory, feel calm and refreshed. According to the research of Harvard Medical School, meditation can improve brain activity, metabolism, blood pressure, respiration and heart rate, lower blood pressure and effectively change cardiopulmonary function.
