It's very hot and I feel very tired.

It is essential to replenish water in air-conditioned rooms. Be sure to drink plenty of water when blowing the air conditioner. According to relevant statistics, the average daily water consumption of normal people is 2000~2500 ml. In addition to 300 ml of water produced by the oxidation of substances in our body, the other 2200 ml should be supplemented from the outside. In summer, the water fluctuates greatly, and the daily water supply should be around 3000 ml. Especially in air-conditioned rooms, there is a lot of water loss, so you should drink water in time. You don't have to wait until you are thirsty to drink water. You should supplement it regularly. In particular, many families blow air conditioners all night. After getting up in the morning, their bodies lose water and there may be some dehydration. It's best to drink a large glass of water first to relieve it. The skin also needs hydration. If you work under air conditioning for a long time, please wear moisturizing skin care products and apply them evenly on your face, neck and limbs to make your skin better fight against "drought". In addition, you can also use hydrating spray to spray water evenly on your face and limbs. When using air conditioning, it is also important to replenish water indoors. When using air conditioning, you can't blindly covet coolness, because the lower the temperature, the lower the air humidity, and the more serious the water loss of people in such an environment. Generally speaking, the temperature of household air conditioner is 24℃~26℃. While controlling the temperature, a basin of water should be put indoors to improve the indoor humidity through the natural evaporation of water. How much is not a big problem. The most important thing is that the mouth of the container, that is, the surface in contact with air, is as large as possible, because evaporation can be strengthened. In addition, sprinkling water, wiping the floor with a wet cloth and other methods to increase indoor humidity can increase indoor humidity. If you really feel dry, especially some patients with chronic diseases, infants and the elderly, you can install humidifiers in air-conditioned rooms. The elderly, children and women are the key prevention groups of "air-conditioned diseases". Families with elderly people, especially those with basic diseases such as hypertension and diabetes, had better not "repeatedly refrigerate" the elderly, otherwise they may catch a cold and have a fever, or even cause the original diseases. For example, it's best not to turn on the air conditioner and don't lay a mat for the elderly, so as not to be unbearable for the elderly. Families with children should also prevent their babies from suffering from air conditioning, because their skin is thin and tender, their subcutaneous fat is low, their capillaries are rich, and their thermoregulatory center is not fully developed. If the air conditioner is not used properly, the baby will be attacked by cold air, the capillaries will contract, the sweat pores will be closed, and the heat in the body will not be emitted, which will easily unbalance the thermoregulation center and the blood circulation center, causing diseases such as colds, fever and cough. If the situation is serious, there may be diseases such as pneumonia and bronchitis; Diarrhea is also a common manifestation of air-conditioning disease in children in summer. Because the air conditioning temperature is too low, it may also aggravate the baby's original asthma, rhinitis and other diseases, and the old disease will recur. If the baby is found to have signs of illness, such as runny nose, stuffy nose, cough, fever, etc. You should control your illness in time. Also let the baby drink more boiled water or light salt water. In and out of the air-conditioned room, you should add or subtract clothes for your baby at any time. It is best for parents to ensure that their baby has a certain amount of time to receive sunshine, go outdoors, breathe fresh air and sunbathe every day. It is best to turn off the air conditioner at night, or cover your baby with a thin quilt or towel, especially to cover your stomach. In order to ensure the baby's health, measure the baby's temperature at least once a day. In addition, because women often wear thin clothes, especially skirts, it is easy for air-conditioning diseases to find you. Women are advised not to be sedentary. If they work at their desks in short skirts, they'd better cover their knees with clothes. Eating more ginger in air-conditioned rooms for a long time can prevent diseases. People in air-conditioned environment often drink ginger soup, which can effectively prevent and treat air-conditioned diseases such as abdominal pain, vomiting and diarrhea, cold, waist and shoulder pain. 1, preventing and treating gastrointestinal dysfunction caused by air conditioning. The navel is the weakest part of the human body to the outside world. In addition, the secretion of gastric acid and digestive juice is reduced in summer, and the ability to resist bacteria is weakened. In air-conditioned places, it is easy to be stimulated by cold and heat, causing gastrointestinal dysfunction, leading to the invasion of bacteria, and gastrointestinal diseases such as vomiting, abdominal pain and diarrhea. Eating ginger or drinking ginger soup properly can play a preventive role. 2, prevention and treatment of early colds. Often in an air-conditioned environment, due to the large temperature difference between indoor and outdoor, it is easy to catch cold when entering and leaving the air-conditioned room. If you can eat a few slices of ginger or drink a bowl of brown sugar ginger soup in time, it will help to dispel cold and relieve exterior syndrome, or soak your feet with ginger soup (adding some salt and vinegar) can also receive good curative effect. Coke can also be boiled with ginger before drinking, but it is not effective for middle and late colds. 3. Prevention and treatment of scapulohumeral periarthritis, a by-product of air conditioning. If you stay in an air-conditioned room for a long time, your shoulders and back are vulnerable to diseases such as wind, cold and humidity, especially the elderly are prone to scapulohumeral periarthritis. In this case, you can cook some hot ginger soup. First add a little salt and vinegar to the hot ginger soup, then wring it out with a towel and apply it to the affected area several times. This method can relax muscles from tension, relax muscles, promote blood circulation, and greatly relieve pain. Although ginger can play a certain role in diet therapy in summer, it is a kind of spicy and dry product, which must be avoided by people with fever due to yin deficiency and pregnant women. Gingerol can also cause degeneration, necrosis and interstitial hyperplasia of hepatocytes in patients with hepatitis, which makes liver function abnormal. Therefore, patients with hepatitis should avoid eating ginger. To prevent air-conditioning diseases, we can mainly start from the following six aspects: first, it is best to control the temperature of the air-conditioned room at around 24 to 26 degrees; This temperature is more comfortable for the human body. Don't turn the temperature of the air conditioner too low, so as to avoid too large a temperature difference with the outdoor, which will make people (especially the middle-aged and the elderly and the infirm) easy to catch a cold. Therefore, the indoor and outdoor temperature difference is generally around 5 degrees. Second, don't turn on the air conditioner for too long, and always open the window for air; Thereby ensuring the exchange of indoor and outdoor air, allowing fresh outdoor air to enter and keeping indoor air clean. Third, don't enter the air-conditioned room with very low temperature immediately when sweating; If you want to enter the air-conditioned room when sweating profusely, you'd better change your wet clothes and dry your sweat first. Don't stand at the air outlet of the air conditioner for a while, especially to avoid the air conditioner blowing directly to your neck. Fourth, don't stay in the air-conditioned room for too long; Three or four hours will do. If you stay for seven or eight hours or even more than 10 hour, it may be bad for your health. Fifth, air conditioners should be cleaned and disinfected frequently; Before using the air conditioner for a long time in summer and winter, it is necessary to clean the filter screen on the air conditioner in time to prevent pathogenic microorganisms from multiplying and growing on the filter screen and bringing harm to the human body. Sixth, it is best not to turn on the air conditioner when sleeping at night; Adjust the air conditioning temperature in time when the temperature is low at night, and cover the abdomen and other parts that are easy to catch cold with towels and quilts. When the temperature is low at night, it is best to turn off the air conditioner and open the window to get some air.
