People often lose too much after sweating in summer, and there will be insufficient nutrition and water in the body. After entering autumn, the weather is getting colder and the climate is dry, which is prone to autumn dryness. Traditional Chinese medicine believes that dryness is the evil of six evils and the main qi in autumn. It is dry and easy to consume body fluids. The so-called "dryness is better than dryness". When body fluids are exhausted, there will be a series of symptoms such as dry mouth, stuffy nose and sore throat, dry skin, dry cough with little phlegm, dry stool, irritability and so on, which is called "autumn dryness syndrome" in medicine. The elderly have poor adaptability and tolerance to autumn climate change, so they should pay more attention to prevention. Physicians of past dynasties believe that the basic principle of preventing dryness in autumn is nourishing yin and clearing dryness, moistening lung and promoting fluid production. Replenishing water is one of the important measures to prevent dryness in autumn. An adult's daily intake of water is at least1500ml. Drink water reasonably, many times in small quantities. It is best to drink 200ml in the morning and 200ml before going to bed. If you exercise a lot and sweat a lot, you should increase the amount of water to let your heart spend the golden autumn. Cough or dry cough without phlegm is easy to occur in autumn. It is best to eat some Sydney and Yali pears at ordinary times. Because pear tastes sweet and cool, it has the effects of moistening lung and quenching thirst, nourishing yin and moistening dryness, resolving phlegm and relaxing bowels. Raw food can clear fire, and cooked food can nourish yin. If you have the conditions, you might as well eat some products that nourish yin and moisten the lungs, such as Sydney cream, nourishing yin and clearing lung cream, etc. You can also eat vinegar at ordinary times, which can not only stimulate appetite, but also inhibit germs and prevent intestinal diseases. Autumn can also be supplemented by proper diet, which can supplement the consumption in summer and lay the foundation for resisting the cold winter. But you can't eat as you like, and you should still follow the principle of "dryness is moist". It is advisable to adopt the method of clearing and supplementing, from slow, less and vegetarian, not too much and too hard, to avoid sudden tonic. Medicinal diets such as sea cucumber, snake meat, soft-shelled turtle, duck meat, duck eggs, radish, tofu, sesame, tremella, lotus root, and traditional Chinese medicines such as Astragalus membranaceus, Ophiopogon japonicus, Adenophora adenophora, lily, lotus seeds, yam, lentils and red dates.

Sun Simiao, a medical scientist in the Tang Dynasty, said in "A Thousand Daughters' Wings": "You should warm your stomach in autumn and winter", so you should also pay attention to warm your stomach and eat cold products carefully, so you should eat less watermelon, cantaloupe and melon in moderation.
