Window ventilation in daily life has been a commonplace problem, but many people know window ventilation but do not know how to correctly open the window ventilation, so today Xiaobian to popular science daily window ventilation misunderstandings, hope to help everyone to develop good window ventilation habits.

Don't open the window for fear of dirt

Many people think that the air outside is so cloudy that they should not open the window for ventilation, but in fact, this idea is not correct. Under normal circumstances, a person needs to exhale 22 liters of carbon dioxide an hour, and if the ventilation is not good, carbon dioxide will accumulate in the room, so there is a certain security risk. Therefore, opening the window for ventilation can obtain more negative ions and increase the life span of people. At the same time, it is recommended that the number of Windows be ventilated 3 times a day, and each time not less than 15 minutes is the most appropriate, and this frequency can basically meet the fresh indoor air.

Open the Windows all morning and all night

To develop the habit of opening the window in the morning and night is actually very good compared to not opening the window, but the best recommendation is to open the window at 10 am - 3 PM is the best, so it is recommended to open the window ventilation during this time.

Only open the window when cooking in the kitchen

Many owners think that the kitchen only opens the window when cooking, in fact, it is not basically open the window when the stove needs to be opened, because at this time there are already a lot of toxic gases produced, so when you should be ready to cook, you should open the kitchen doors and Windows in advance for ventilation.

Sleep without opening the window

Many people like to close their doors and Windows when they sleep, so that they can avoid getting cold. This idea is indeed correct, but Xiaobian suggests that the window should not be opened so large before going to bed but should also be kept open, so that it can achieve good ventilation, while avoiding the wind blowing directly to the body.

We don't open the Windows in hazy weather

In hazy weather, it is true to open the window less, but it is not all day long. It is recommended to open the Windows a little smaller in hazy weather, but put a pan of water next to the heater to increase the humidity of the air and let the dust microorganisms sink.
