No matter when the window ventilation has been a cliche problem, many people know the truth of window ventilation but do not know how to correctly open the window ventilation, today Xiaobian will detail the misunderstanding of window ventilation and establish the correct window ventilation habit, hope to help you!

Mistake one: afraid of dirty do not open the window

Many parents who love cleanliness think that they have worked so hard to clean the family if they often open the window, it will be easy to be messy and then simply don't open the window. In fact, it is wrong to have such an idea. The window should be opened every day, because normally a person will exhale 22 liters of carbon dioxide in an hour. If the ventilation is not good, the carbon dioxide cannot be exchanged through the air in time and will be produced indoors, which will cause health risks to the human body. It is recommended to open Windows for ventilation at least three times a day for at least 15 minutes at a time so as to keep the room full of air.

Myth 2: Opening the window early in the morning and late at night

Many people think that the air in the morning and evening is the freshest. In fact, the best time to open the window is from 10:00 a.m. to 3:00 p.m., which is the best time to open the window for ventilation. Keeping the window open at this time can make the indoor air more fresh and comfortable.

Myth 3: Only open the window when you're cooking

Nowadays, every household has a smoking machine, so many people think that a range hood should be opened to stir fry without opening the window, even if it is boiling water. In fact, this practice is very unsafe, no matter when cooking or boiling water should always open the doors and Windows, so as to be able to maintain a safe cooking environment.

Mistake four: sleep without opening the window

Many people like to close their doors and Windows when they go to bed to avoid catching cold. In fact, sleep with the window as open as possible, but to avoid the wind, don't let the wind directly on your body. It is recommended that you can install hanging Windows inside or outside the bedroom area. Unlike flat opening, these two ways of opening can effectively avoid the wind blowing directly to the human body, but also good ventilation, practical and healthy.
