[ Chinese wardrobe net ] In the cold winter, people close their doors and windows because they are afraid of cold, but they neglect the harm caused by closed doors and windows: First, it is easy to spread diseases, and second, it is easy. Breathe into the polluted air inside the room. Therefore, Xiaobian here suggests that everyone should develop a good habit of opening windows in the winter, which is good for our health.
Modern medical research believes that there are hundreds of bacteria and viruses in the mucosa of normal people's throat. When talking, coughing, or sneezing, these germs will splash into the surrounding air with the sputum. In the cold winter, if the doors and windows are closed for a long time, the bacteria in the room will accumulate and it will cause infection.
In winter, if a person stays in the room for 24 hours without changing the fresh air, the indoor carbon dioxide content will increase. When the carbon dioxide in the air increases sharply and the oxygen is greatly reduced, dizziness, fatigue, chest tightness, irritability, etc. often occur. . This is because the brain is extremely sensitive to the lack of oxygen.
In terms of indoor air pollution, the dangers caused by various new types of construction, decorative materials and household chemicals are also unconsciously occurring. Nowadays, the sealing degree of some new buildings is increasing. Once the indoor air is polluted, the pollutants are difficult to discharge in time.
Open door and window is the most effective and simple way to solve air pollution and purify the environment. Ventilation in the winter window does not take a long time, such as 80 square meters of living room, the window opening time is usually 30 minutes is enough. Do not open the doors and windows to avoid convective winds. The tuyere is not directly facing the person sitting and lying down. Since the glass can absorb the ultraviolet rays in the sunlight, open the window, and the sunlight directly shines into the room, the ultraviolet rays can fully play the role of disinfection and antivirus. In this way, there is no cold and cold, and the polluted air in the room can be discharged in time, and fresh outdoor air will come from it.
The following measures can be taken to purify indoor air in winter:
First, open windows every day to keep the indoor air fresh.
In the winter, conditional office buildings and families are ventilated for 20 minutes each morning, mid, and evening. Experiments have shown that 60% of harmful gases in indoor air can be removed every time the chamber is ventilated.
Second, choose a suitable indoor air purifier, often indoor air purification and disinfection.
In the winter, in the period of high incidence of influenza, vinegar can be used to purify the air, because vinegar volatilization has a bactericidal effect in the air.
Third, maintain a proper indoor temperature to avoid excessive temperature difference between indoor and outdoor.
In winter, the room temperature is generally controlled at 20 ° C - 23 ° C.
Fourth, increase indoor humidity.
In winter, the most suitable indoor humidity is 30%-60%. You can use a humidifier, or put a small sink on the radiator, or grow flowers indoors to increase the humidity of the indoor air.
Fifth, the living environment should be cleaned frequently to prevent bacteria in the indoor air from exceeding the standard.
Winter, especially in closed office buildings, families with patients, children's rooms and families with pets should pay special attention.
