When sleeping, the indoor space is often closed. After breathing and breathing all night, the air in the bedroom is often a little bad. Not only a lot of carbon dioxide is accumulated, but also oxygen becomes very thin. When bedding is arranged, dust mites, dandruff and other small pollutants will float in the air. At this time, window ventilation is particularly important. But the window opening time should not be too early, especially in the city, the pollutant concentration in the air is still high at 6:00 and 7:00 in the morning. It is better to wait until the dirty air deposited on the ground is lifted up and then open the window for air exchange. The window can be opened at about 8:00 in the morning, when the temperature rises, the air quality becomes slightly better. It needs to be reminded that cardiovascular patients are vulnerable to cold air and other stimuli, so they must wear more clothes after getting up, and open windows after getting used to the temperature. When sleeping, the indoor space is often closed
Mites like warm, humid environment, quilt is its favorite home. Quilt will be stained with human sweat, some slightly damp, at this time the temperature, humidity is most suitable for mite survival. In the south, the air humidity is high, and the quilt is more common. Window ventilation is a good way to keep the quilt dry. After getting up, don’t rush to fold the quilt. It’s better to pave the quilt in turn, and then open the window to let the quilt ventilate, promote the evaporation of water vapor in the quilt, and avoid the breeding of mites and molds.
Chinese cooking methods such as frying, frying, frying and frying will produce a lot of oil smoke, and the food materials will volatilize a lot of harmful substances under high temperature, which has strong irritation to the nose, eyes and throat mucosa, and can cause respiratory system diseases such as rhinitis, laryngitis and tracheitis, and the gas and natural gas may release harmful gases such as carbon monoxide when burning. Therefore, when cooking, you should not only turn on the range hood, but also open a window for ventilation. You’d better let the air have convection. After cooking, you should also continue to open the window for ventilation for at least 10 minutes to avoid the deposition of lampblack at home. The range hood should be opened early and closed late, that is, it should be opened before cooking, and opened for another 5 minutes after cooking.
After bathing, the water vapor in the toilet condenses and the humidity is very high, so it must be ventilated and dried in time, otherwise it is easy to produce a large number of molds and threaten health. If there is a window in the toilet, it is necessary to open the window in time after bathing and open the toilet door to ensure air convection; if there is no window, it is necessary to install a high-power and good performance exhaust fan. After bathing, the water vapor in the toilet condenses and the humidity is very high. It must be ventilated and dried in time.
Formaldehyde is the number one killer of indoor pollution. After decoration, the parts with more boards such as wardrobes and cabinets will release formaldehyde and other pollutants to the interior for decades. If there is a peculiar smell in the cabinet at home, you can open the wardrobe, cupboard, bookcase, drawer, etc. when you go out in the daytime, and open a small gap in the window at the same time to fully release the pollutants. If you think the indoor pollution is serious, you can open the kitchen and bathroom door at the same time, open the ventilation function of the ventilator, range hood or air conditioner, and accelerate the diffusion of pollutants.
When cleaning the room, it is the most intensive time of pollutants in the indoor air. When you clean a sofa, mattress or carpet, a large number of hidden bacteria, dust mites and dandruff will float in the air, and pollutants will be raised when you use a vacuum cleaner. At this time, it is better to put on the mask and ensure the ventilation of windows to avoid inhalation of fine particles. When cleaning, it is better to wet clean first, for example, wipe the tabletop and cabinet surface with a wet cloth to reduce the floating objects in the air.
The window can be opened for ventilation for 15 minutes half an hour before going to bed every night. It is better to keep the air convection. It can not only avoid the air pollution caused by car exhaust and factory production, but also increase the oxygen in the air, which is conducive to sleep. When opening the window, the elderly and children should try to keep away from the window. When sleeping, the bedroom doors and windows should not be closed tightly, so as not to affect sleep due to lack of oxygen. You can open a small gap in the door or window to let fresh air into the bedroom. If the window is facing the head, it’s better to use curtains and other covers to avoid direct blowing.
Opening a window can not only freshen the “dirty” air in the room in time, but also prevent the occurrence of some diseases, especially in the above seven moments.
