Because of the epidemic, our daily greeting habits change from "Have you eaten?" It became "Did the nucleic acid do it?" . This epidemic has penetrated into every part of our lives. I used to be afraid that the mobile phone was out of power, but now I am afraid that the signal will be poor when scanning the code. Because there is no signal, I can't scan the local code and display the green code when entering the gate. In the second half of this year, epidemic cases increased from time to time all over the country, while Guangzhou faced the most severe test since the outbreak of the epidemic. When will the epidemic end? For three years, there is no answer. Because this is the first time for all mankind to face a difficult problem that cannot be completely solved by current medicine. In the face of the current epidemic, immunity is our body's best weapon against the virus. How to improve body immunity? You can refer to these points: picture 1. Drinking more water and boiling water is the first thing to improve immunity. Drinking more water can keep the mucous membrane in the nasal cavity moist, and drinking more water can also make us feel fresh and full of vitality. Because boiled water helps to promote human metabolism, it is a good catalyst. Water is easily absorbed by our body, which enhances the activity of lactate dehydrogenase in various organs of the body, thus enhancing human immunity and disease resistance. Drinking a cup of warm water or normal temperature water in the morning is better for your health. Figure 2. Good sleep and high-quality sleep can promote the human body to produce more sleep factors, which can promote the increase of white blood cells and strengthen the detoxification ability of the liver, thus eliminating bacteria and viruses that invade the human body. Therefore, high-quality sleep helps to improve human immunity. All-round ventilation during the day can refresh the air, and proper ventilation at night can help you sleep and breathe fresh air.

If people are under extreme pressure for a long time, it will lead to the decline of T lymphocyte activity and macrophage activity, and weaken the immune response. Therefore, in the face of pressure, we should learn to decompress ourselves. We can relieve the pressure through sports, games and singing. Photo ● 4. Drink tea often, especially green tea. Green tea is rich in polyphenols and other nutrients, which can stimulate the body to produce antioxidants and detoxification enzymes. Green tea also contains tannic acid and vitamin C, which can kill many kinds of bacteria, fight infectious diseases and improve immunity. ●5. A balanced diet and a scientifically matched diet can ensure a balanced intake of various nutrients, which can not only improve personal nutritional status, but also enhance resistance. Pay attention to the food collocation of three meals a day, including coarse food, fine food, dry food, vegetarian food, cold food and hot food. Photo ● 6. During the prevalence of moderate exercise, many people stay at home, but this does not mean that physical exercise, especially scientific physical exercise, can be ignored. At present, everyone can do some moderate-intensity full-body exercises, such as aerobics, yoga, floor exercises, health qigong and other items suitable for indoor sports. Another advantage of physical exercise is that it has a positive impact on people's psychology. During the epidemic, some people will have some negative emotions, such as anxiety, panic, irritability and depression. Proper physical exercise will alleviate these negative emotions. Nutritionist's suggestion: these foods can be eaten more 1, and poultry meat refers to chicken, duck, goose, pigeon, quail and other meat. The protein nutrition of poultry meat is almost the same as that of livestock meat, but the saturated fatty acid content is lower than that of livestock meat. Eating poultry meat is more beneficial to health than eating livestock meat. 2. The muscle of fish contains 15%-20% protein, and because the muscle fiber is short and smooth, it is easier to digest than beef and pork. More importantly, the fat content of fish is only 1%-3%, and the main components are long-chain polyunsaturated fatty acids, such as EPA and DHA, commonly known as "brain gold". It is worth noting that EPA can reduce blood lipids and prevent coronary heart disease. DHA is necessary for the development of brain and retina of fetus and baby, so fish should be the first choice when choosing meat food. 3. Vegetables can be roughly divided into three categories: leafy vegetables (such as Chinese cabbage, amaranth and Chinese flowering cabbage), melons and tomatoes (such as green peppers, cucumbers and tomatoes) and roots (such as potatoes and carrots). Contains a variety of minerals, vitamins and dietary fiber, which plays an important role in human physiological activities. The vitamins provided to the human body are mainly folic acid, carotene and B vitamins.
