Living in the city in the morning to open windows is harmful to health

Getting up to open the window for ventilation in the morning seems like a pleasant thing, but for people living in the city, this approach is preferable.

hzh{display:none;}  一些车流量较大的街道,夜间城市底层大气比白天稳定,不利于污染物的扩散,所以早晨6时左右,污染物浓度依然很高。Opening windows in the early morning to change into the fresh air is harmful to your health.

  First of all, the windows should be opened once a day in the morning and afternoon each time, more than half an hour each time, 9 am?
11 am, 2 pm
4 o’clock is the best time to open the window for ventilation, because the air quality is the best in these two periods.

In addition, the kitchen is an important source of indoor air pollution. Exhaust fans or cooker hoods should be turned on when cooking to remove harmful gases in a timely manner.

  Benefits of window opening ventilation: Frequent window opening ventilation can effectively remove harmful gases in indoor air and purify indoor air.

  According to measurements, when all the doors and windows are open and the indoor and outdoor air convection is good, the indoor and building air can be exchanged again after 15 minutes.

  Frequent opening of windows for ventilation can greatly reduce the content of germs in indoor air.

  According to measurements, in the environment where the doors and windows are tightly closed and the air is dirty, the number of bacteria in each cubic meter of air can be as high as tens of thousands. After opening the window and ventilating, only a few bacteria are left.

  After opening the window, more sunlight can be allowed to enter the room, so that the ultraviolet rays blocked by the glass can directly enter the room for sterilization and disinfection.

  Frequent opening of windows for ventilation can increase the content of negative ions in indoor air.

  Every cubic centimeter of air in a city’s home contains only 40 negative ions?
50, and there can be 100 in the air above?
200; can rural fields contain 700?
1,000 in the air of forests and seashores.

  Because the negative ions in the air can improve the ventilation function of the lungs, stimulate the central nervous system, promote blood circulation and hematopoiesis, and enhance cerebral cortical functions, they are known as “air vitamins”.

The increase in the content of negative ions in the indoor air makes people refreshed, feel comfortable and healthy.
