It's freezing cold in winter. Everyone likes to close the doors and windows and enjoy the heating in the house. But what you don't know is that if ventilation is not done well, the potential safety hazard is very great. Eight of the 15 articles of the World Health Organization's "Healthy Housing" standard are related to indoor air quality, so in this winter, follow Xiao Kai to open the window correctly for ventilation ~
Misunderstanding 1: Don't open the window if it is too cold
Correct practice: No matter how cold it is, one must open
. Under normal circumstances, one must exhale 22 litres of carbon dioxide per hour. If ventilation is poor, the carbon dioxide exhaled by the human body will gather indoors. Window ventilation can make people get more "air vitamins", that is, negative ions, can increase the life of people. The more windows are opened, the better. Opening windows for ventilation 3 times a day, each time not less than 15 minutes, can basically maintain the freshness of indoor air.
Misunderstanding 2: Open windows early in the morning and one night
Correct practice: 10:00am-3:00pm Best Window Opening
Many people are used to opening windows before going to work in the morning and coming back at night. According to research tests, the two air pollution peaks in the city are usually around sunrise and in the evening, which is the most inappropriate time to open windows. The two opposite air cleaning periods are around 10 am and 3 pm. It is recommended that you open more windows during this period.
Misunderstanding 3: Open the window only when cooking in the kitchen
Correct practice: Open the window as long as you use the stove
Now almost every family uses a range hood, but some friends only use the range hood and open the window when cooking, but do not use the range hood or open the window when boiling water and stewing soup. In fact, even if it is only boiling water, the exhaust gas of gas can easily gather in the kitchen and spread to the living room and bedroom. Therefore, when using gas, no matter what you cook, you must open the window or use the range hood.
Misunderstanding 4: Can't open windows when sleeping in winter
Correct practice: Can open seams properly
When sleeping in winter, many people always like to close the doors and windows to avoid catching cold. In fact, when sleeping in winter, the windows should be opened as far as possible, but convection winds should be avoided and the wind should not blow directly on the body. Sick or encounter strong wind, heavy rain should not open the window.
Misunderstanding 5: Window cannot be opened in smoggy days
Correct practice: Window opening needs to be done regularly in smoggy days
When smoggy is very serious, window opening time needs to be reduced. It is best to open the window a little smaller when there are screens, and use a humidifier, humidification spray, or put a basin of water on the heating to increase the air humidity and let the dust and microorganisms sink.
Misunderstanding 6: Air Purifier Enough
Correct Practice: Natural Ventilation Is King
At present, the general air purifier on the market can only remove dust, oil fume and peculiar smell, and can kill bacteria and viruses slightly better. However, the use of air purifiers in enclosed spaces for a long time may cause secondary pollution. When the air quality improves, there is no need to open the air purifier for a long time. Natural ventilation should be the best choice.
