Chinese medicine believes that the sun's spirit began to sprout when it was in beginning of spring. If we can take advantage of the rising yang and vigorous metabolism in spring and adopt scientific health preservation methods, it will be very beneficial to fitness and disease prevention all year round. The following are the "three noes" principles of spring maintenance for middle-aged and elderly people.

1. There is no "acid".

Spring diet should be "sour and sweet", because liver yang is hyperactive in spring. If you eat acidic food again, it will easily lead to excessive liver qi, and liver exuberance will easily damage the spleen and stomach. Therefore, the spring diet should avoid "acid".

Acidic foods include mutton, dog meat, quail, fried peanuts, fried melon seeds, marine fish, shrimps and crabs. It is advisable to eat sweet and spleen-strengthening products, such as yam, bamboo shoots, spinach, jujube and leek. Chinese yam 30g coix seed 30g, millet 75g, lotus seed 25g, jujube 10 porridge, and a little sugar can be added as staple food for long-term consumption.

2. Not "quiet".

In spring, the yang in nature begins to rise, and the human body should rely on this natural feature to focus on yang. The key to tonifying yang is "dynamic", not "static".

The elderly should actively carry out outdoor exercise to improve the efficiency of cerebral cortex, enhance cardiopulmonary function and prevent arteriosclerosis. However, the elderly should not do spring exercises too early to prevent cold, asthma and chronic bronchitis caused by low temperature and fog in the morning. They should go out to exercise after the sun rises. In addition, spring training can not be on an empty stomach. Old people have slow blood flow and low body temperature in the morning. They should drink some hot soup before exercise. At the same time, exercise should be slow. After getting up in the morning, the muscles of the elderly are slack and the joints and ligaments are stiff. Gently move your body joints before exercise to prevent accidents caused by sudden exercise.

3. Don't be angry.

Spring is the time when the liver yang is excited, and the mood is irritable, so we should be open-minded and harmonious.

A good mood helps to nourish the liver, because depression will lead to stagnation of liver qi, affect the function of soothing the liver and regulating qi, reduce immunity, and easily lead to mental illness, liver disease, cardiovascular and cerebrovascular diseases and so on.
