Opening the window in the morning is not good for your health.

It’s a very pleasant thing to get up and open the window in the morning, but it’s a good thing for people living in the city.

  In some streets where traffic flows through, the transitional atmosphere in the night city is more stable than during the day, which is not conducive to its own spread. Therefore, at around 6 am, the concentration limit is still high.

Opening the window in the early morning to change into the air that is not fresh is harmful to health.

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

In addition, the kitchen is an important source of indoor air pollution. When cooking, open the exhaust fan or range hood to eliminate harmful gases.

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

  According to the measurement, when the doors and windows are all open and the indoor and outdoor air convection is good, the air in the room and the building can be exchanged once in 15 minutes.

  Frequent window ventilation and ventilation can greatly reduce the amount of bacteria in the indoor air.

  According to the measurement, in the environment where the doors and windows are closed and the air is dirty, the number of bacteria per cubic meter of air can be as high as tens of thousands, and the number of bacteria is only a few hundred after the window is ventilated.

  After opening the window, it allows more sunlight to enter the room, so that the ultraviolet rays blocked by the glass directly enter the room, and disinfection.

  Frequent window ventilation and ventilation can increase the content of negative ions in indoor air.

  In the average urban living room, there is only negative ion 40 per cubic centimeter of air?
50, and there can be 100 in the upper air?
200; the air in rural fields can contain 700?
1000, and more than 20,000 in the air of forests and beaches.

  Negative ions in the air are known as “air vitamins” because they improve the ventilation function of the lungs, stimulate the central nervous system, promote blood circulation and hematopoiesis, and enhance the function of the cerebral cortex.

The increase in the content of negative ions in the indoor air makes the mind fresh, comfortable and healthy.
