1, nourish yin and drink plenty of water. In dry winter, more than 600 ml of water evaporates through the skin every day, so it is very important to replenish water. An adult should drink at least 1500ml of water every day, and 2000ml in autumn can ensure the lubrication of lungs and respiratory tract. Although it is recommended to drink more water every day for health, weight loss and beauty. Drinking a lot of water at a time without thirst will be counterproductive. When water exceeds the amount necessary for the body, the water content in cells will rise and swell. The worst result will be "water poisoning" and life-threatening. The correct amount of drinking water should be adjusted according to one's daily activities. Under normal circumstances, drink at least 1.5~2L of water every day. Control the water consumption at 1~2 cups each time.

2. Keep warm when dressing. Dressing in winter is one of the most important means to prevent diseases. Keeping warm can help us to prevent diseases better, so we should pay attention to keeping warm when dressing in winter. Some people are careless and didn't add clothes in time when it was cold; Some people wear less clothes and don't button their coats for beauty. Early in the morning and at night when the cold wind is strong, the abdomen is easy to catch cold. Especially for women with spleen and stomach deficiency and cold, once it is cold, they will have stomachache and diarrhea, which is a natural reaction of gastrointestinal tract. The best and most convenient way is to put on more clothes, especially to wrap your waist and abdomen tightly. The first criterion for choosing winter clothes is to keep warm. Among many kinds of clothing materials, wool, chlorine fiber, acrylic fiber, silk and acetate fiber viscose cotton have the highest warmth retention, while nylon, polypropylene fiber and polyester are not suitable for keeping out the cold because of their high thermal conductivity. The more air the fabric contains, the better its warmth retention. Thick wool fabrics and silk contain a lot of air, so they keep warm well. In particular, the pores of wool fabrics are not straight through, which has better warmth retention.

3, diet pays attention to appetizing and moistening. Eat more warm food, such as sesame, walnut, glutinous rice and so on. You can also eat more spicy, sour, moist or lung-lowering fruits and vegetables, especially white radish and carrot. Although winter health is mainly based on eating "bitter" fruits and vegetables, you should not eat too much and support too much, so as not to cause gastrointestinal stagnation. It is worth reminding that after the autumnal equinox, the cold breath is getting stronger and stronger. People with poor spleen and stomach and frequent diarrhea can easily induce or aggravate diseases if they eat too much fruit. For athletes, after each exercise, they should eat more foods that nourish yin and moisten the lungs and replenish body fluids, such as pears, sesame seeds, honey and tremella, which can effectively prevent autumn dryness. If you sweat a lot, you can also add some salt water in moderation. The medicinal diet of autumn equinox can make good use of lilies, such as lily lotus seed soup, lily lotus seed lean broth, tremella lily soup and so on.
