In winter, the yang of the human body is suppressed, and the physiological activities of the human body also converge. At this time, the kidney should not only prepare enough energy to maintain the heat expenditure in winter, but also store some energy for the coming year, so it is very important to tonify the kidney at this time. In diet, we should always pay attention to the nursed back to health of the kidneys, pay attention to the supplement of calories, eat more animal foods and beans, and supplement vitamins and inorganic salts. Sticky food is mostly cloudy, and eating this kind of food in winter is easy to damage the spleen and stomach. Moreover, food overheating is easy to damage the esophagus, and after entering the stomach, it is easy to cause heat accumulation in the body and cause diseases; If the food is too cold, it will easily stimulate the blood vessels in the spleen and stomach and make the blood flow poor. However, the decrease of blood volume will seriously affect the blood circulation of other organs and endanger human health. Therefore, the diet in winter should be gentle.

Live and stay healthy. In winter, in order to resist the cold, people take various measures to keep warm, but the methods must be proper to achieve the purpose of health preservation. Therefore, winter health needs the following points: "Go to bed early and get up late" in winter, and the best time to get up is after the sun comes out. Because going to bed early can maintain human yang and keep the body warm, while getting up late can nourish human yin. Do it at sunrise, get up and stop the cold, and ask for its warmth. Don't sleep with your head covered when it is warm. If the air in the bed is not circulating, there will be less and less oxygen. Over time, the air will become turbid. When people sleep in such an environment, they will feel chest tightness, nausea, or wake up from sleep with a cold sweat and feel tired the next day.

The environmental temperature in winter is quite different from the human body temperature, so the discomfort is more obvious than other seasons. Especially for the elderly and people with weak physique, the harsh environment of ice and snow not only affects health, but also brings potential dangers to travel. The ideal environment is very necessary for cold protection and health preservation. It is cold outside in winter, and the temperature difference between indoor and outdoor is large. If the room temperature is too high, it will make people feel stuffy or dry and dizzy. After a long time, it will also cause dry mouth and dry eyes. Over time, it will break the physiological balance of the human body and cause diseases. Especially in the north, high room temperature is particularly easy to cause exogenous cold. If the indoor temperature is too low, it will greatly consume the thermal energy of the human body and make people feel cold; People who are weak will cause chills; If the indoor humidity is too low and the air is dry, people will feel thirsty and the respiratory tract will be dry and uncomfortable. At the same time, we should keep the habit of opening windows frequently in winter, keep the air circulating and avoid harmful bacteria staying indoors.

Exercise. In winter, many people are reluctant to take part in sports because of the cold climate. Cold-resistant exercise is beneficial to people, and at the same time, cold resistance can make people live longer. For young people, cold tolerance can also exercise people's strong will and tenacious spirit, which should be advocated in particular. Although people's cold tolerance is limited, and people with different constitutions have different responses to cold stimuli, it is certain that exercise can improve the body's tolerance to cold.

Psychiatry. In the cold winter, the north wind blows, the vegetation withers, the yang hides and the yin is vigorous, and the metabolism of yin and yang in the human body is also at a relatively slow level. Therefore, spiritual recuperation should also focus on "hiding", that is, keeping the spirit quiet. In addition, seasonal affective disorder should be prevented. It refers to the phenomenon that some people are depressed, lazy, sleepy and groggy in winter, which is mainly caused by the cold climate. But keeping warm blindly can't achieve the preventive effect.
