The walls and floors at home are sweating. Why?

It is necessary to close the window when it rains. When humid air strikes, always remember to close the windows at home, especially the windows facing south, so as not to give any chance for the moisture eyeing outside the window to sneak in. The most important time is in the morning and evening, when the air humidity is higher than at noon. If the doors and windows are not closed in time, water vapor will seriously penetrate into every corner of the house. If you feel that closed doors and windows prevent indoor air from circulating, you can open more doors and windows at noon and afternoon. Occasionally, the most convenient way to prevent moisture in an air-conditioned room is to use a dehumidifier or turn on the air conditioner from time to time to extract moisture from the air. Air conditioning is not only used to adjust the indoor temperature, which is warm in winter and cool in summer, but also can be used as a "dryer" to prevent clothes and furniture from getting damp and moldy in the wet season of spring. In addition, experts remind consumers not to be blind when buying dehumidifiers. The average family only needs to buy a machine with a daily dehumidification capacity of about 16 liter. It is very important to place desiccant. At present, there are many desiccants specially used for moisture prevention and dehumidification in the market, and the most common ones are moisture absorption boxes and dehumidification bags. Generally, the absorption box has various scents, and it is suitable to be placed between the corner of the sofa and the living room, under the bed in the bedroom and under the cupboard in the kitchen. The dehumidifying bag made of absorbent resin and charcoal is more suitable to be placed in narrow spaces, such as closets such as wardrobes and shoe cabinets, and a bag of dehumidifying bag can be hung to discharge moisture. It is best to turn on household appliances once a day. When the air humidity is too high, water vapor is easily attached to the surface and inside of household appliances, and the image and sound quality will be affected to varying degrees, even leading to short circuit and burning components. In order to effectively prevent household appliances from getting wet, it is best to turn them on once a day to achieve the purpose of dehumidification with the heat generated by the fuselage. The best way to keep the computer dry is to turn it on frequently, and use the high temperature generated by the computer operation to disperse the water vapor, and it is best to put the computer in an air-conditioned room to give it a dry and cool environment. (Wan Yun) Health attackers support "umbrella". Rheumatoid patients are prone to get sick because of high humidity. Keep warm. There is more and more rain these days, and the weather is humid. People who usually have low back pain, low back pain and neck and shoulder pain will have more obvious symptoms at this time. The reporter learned from the Second People's Hospital of Shenzhen that the number of rheumatism patients who went to the hospital recently was 20% more than usual. Dr. Xu Chi from Rheumatology Clinic reminded patients with rheumatism to keep warm when the weather changes, especially when the temperature drops. If the air humidity is high, you need to close the doors and windows, don't go out and do some exercise indoors. If it is an old patient, increase the dose according to your own situation. You can go to a big hospital if you feel unwell. Patients with chronic obstructive pulmonary disease with low pressure have poor breathing. Umbrella can improve immunity. In rainy weather, the air pressure is relatively low, and patients with chronic obstructive pulmonary disease feel hypoxia. Moreover, the air humidity is high, and the hypotonic liquid can also stimulate the airway, making the patient feel poor breathing. And this kind of hot and cold weather is easy to catch a cold if you are not careful. Experts believe that the key to COPD is to prevent respiratory tract infection and improve resistance, especially immunotherapy in remission, such as vaccinating COPD patients with pneumococcal and influenza vaccines, improving immunity and reducing infection opportunities. Children with high humidity are easy to get a "wet disease" umbrella, eat less, catch cold, and when it rains, the humidity rises. Most of children's diseases are mainly respiratory infections, including colds, tonsillitis, bronchitis, pneumonia, abdominal pain and so on. Some children even have recurrent attacks and it is not easy to recover. Moreover, a large number of cold fruits and vegetables are on the market at this time, and children's uncontrolled diet, eating moldy food or not paying attention to reasonable nutrition collocation are the main reasons for children's "wet disease". Doctors advise parents to strengthen their children's physical exercise and enhance their physique. During this time, bacteria are easy to multiply, so parents should pay attention to their children's food hygiene, don't eat raw seafood, and don't eat moldy food. (Yu Hairong)
