Do a few things for health preservation in winter.

First, keep indoor air circulation:

1. In winter, people are used to closing the doors and windows of the house tightly, which will cause the indoor carbon dioxide concentration to be too high. If you add the decomposition products of sweat and the bad gas discharged from the digestive tract, the indoor air will be seriously polluted.

2. People will experience dizziness, fatigue, nausea and loss of appetite in such an environment.

In addition, winter is a good season for carbon monoxide poisoning, so it is necessary to keep the indoor air circulating and fresh.

Second, adjust the diet:

1, the nutritional characteristics of winter diet should be: sufficient heat intake, suitable for cold and activities.

2. The proportion of nutrients should be protein, fat and carbohydrate, accounting for 15~23%, 25~35% and 60~70% respectively. The intake of minerals is also slightly higher than usual. In the vitamin part, we should pay special attention to increasing the demand for vitamin C, ingesting enough animal food and soybeans to meet the demand for high-quality protein, and appropriately increasing oil, of which vegetable oil should account for more than half. In addition, the intake of vegetables, fruits and milk should be sufficient.

Third, the folding of the Yin to protect Yang:

1. In winter, cold air attacks people, which easily damages the yang of human body. Therefore, winter health care should start from gathering yin and protecting yang.

First of all, try to go to bed early and get up late. Going to bed early and getting up late in winter, keeping a long rest time, can make the will quiet and the latent yang of the human body will not be disturbed, which is the first thing to pay attention to in winter health care.

Secondly, pay great attention to keeping your back warm. The back is the yang in the yang, and pathogenic factors such as wind and cold can easily invade through the back of the human body, causing diseases. Old people, children and the infirm should pay attention to keeping their backs warm in winter so as not to hurt the sun.

3. Then keep warm from the cold. In winter, the climate is cold, so people should pay attention to stay indoors in warm rooms as much as possible and reduce the number of outings. If you want to go out, you should wear warm clothes, shoes and socks.

In addition, it needs special attention that taking a bath in winter will cause colds and respiratory diseases if you are not careful. Therefore, it is necessary to reduce the number of baths, keep warm when bathing, and pay attention to children, the elderly and patients with cardiovascular and cerebrovascular diseases.

Fourth, moderate tonic:

1, in the general public's idea, cold winter is a good opportunity for tonic, and Chinese medicine attaches great importance to the regulation and nourishing of the human body. According to the theory that heaven corresponds to man and time corresponds to dirty, winter belongs to the kidney, which governs dirty essence and is the essence of life, so winter is the best season for tonic among the four seasons. It means that the weather corresponds to the four seasons of the human body, and the kidneys should be recuperated in winter. Kidney is the element of life. It is very important to tonify the kidney this winter, which makes the body strong.

2. According to the principle of "deficiency supplements it, and cold warms it", we should eat more warm foods in winter meals, especially warm and kidney-yang foods, in order to improve the cold tolerance of human body. In winter, you should choose foods rich in protein, vitamins and digestible foods. Optional food: brown rice, corn, wheat, black beans, peas and other beans; Ginger, leek, garlic, radish, cauliflower, fungus and other vegetables; Mutton, beef, chicken, pork loin and meat such as eel, carp, silver carp, hairtail and shrimp; Walnut, longan, chestnut, sesame and other fruits. Older people with weak physique can often eat stewed chicken, lean meat and tendons in winter, and often drink milk and soybean milk, which can enhance their physique.

Modern medicine believes that winter tonic can improve human immune function, promote metabolism and improve the phenomenon of chills. Tonifying in winter can also regulate the metabolism of substances in the body, so that the energy transformed by nutrients can be stored in the body to the maximum extent, which is helpful to the rise of yang in the body and lays the foundation for health in the coming year.

It is especially important to point out that it is best to consult a doctor for tonic in winter, so as not to misuse inappropriate drugs and cause physical discomfort. For example, people with gastrointestinal problems must carefully choose the appropriate medicated diet, otherwise the tonic is too greasy and spicy, which is easy to cause gastrointestinal damage. It is best to ask Chinese medicine practitioners to prepare prescriptions suitable for the individual's stomach and stew medicinal meals with different tastes, which can not only achieve the purpose of tonic in winter, but also strengthen the spleen and nourish the stomach.
