What is the appropriate indoor temperature and humidity in winter? Experimental determination, the most pleasant indoor temperature and humidity are: 18℃~25℃ in winter, 30%~80%, and how much is the appropriate air conditioner to turn on in winter? When the room temperature is 19℃~24℃ and the humidity is 40%~50%, the human body feels the most comfortable.
For people who need to go out frequently, the room temperature is too high, which will increase the temperature difference between indoor and outdoors, which will reduce their resistance, which will cause abnormal dryness in the indoor air, destroy the warm and humid environment in the body, and affect their body fluid secretion. It will not only make people feel hot all over, but also have difficulty breathing, and the feeling of abnormal dryness in the eyes, ears, eyes, mouth, nose, throat, skin, etc.
If the indoor temperature is too low, it will cause the body's metabolic function to decrease, pulse and breathing slow down, subcutaneous blood vessels contract, excessive skin tension, and weaken respiratory resistance, which can easily induce respiratory diseases. Friends should be reminded to open windows appropriately to ensure living comfort, and it is best to put a basin of water indoors or use a humidifier to increase indoor humidity.
It is cold in winter, and everyone likes to stay at home and enjoy the heating. This brings up a problem: if you don’t open the windows to ventilate, you are afraid that you will get sick; if you open the windows to ventilate, you are afraid that cold air will come in and blow it away. Experts remind: "In winter, windows should be opened for ventilation, and we should pay attention to the method."
“ According to statistics, the number of deaths caused by indoor air pollution in my country each year is 111,000. In winter, the air is dry, the reproduction and spread of microorganisms is accelerated, and the resistance of the human respiratory system is reduced, which is more likely to cause respiratory diseases. ”When opening the windows for ventilation, pay attention to the number of times, time, environment and indoor personnel.
First, it is best to open the windows for ventilation three times every day in the morning, afternoon and evening. “Some people think that the more windows are opened, the better, but this is not the case, because frequent windows will reduce the room temperature, and the elderly and children are prone to illness. ”
Secondly, when the room is smaller, windy or cold outdoors, the window opening time should be shorter; when the room is larger, windy or warm outdoors, the window opening time should be longer. Taking an 80 square meter room as an example, opening the window in the absence of wind or breeze can reduce the pathogenic microorganisms by 60% for about 20 minutes.
Third, if the outdoors are roads and there are many pollutants, the window opening time needs to be changed. “Be a little ahead of the morning and drag a little behind at night, and try to open the window to breathe when there are fewer cars. If you encounter windy and sandy weather, it is best to open the window smaller when there are screens. And use a humidifier, a humidification spray, or put a basin of water on the heating to increase air humidity and let the dust and microorganisms sink. ”
Fourth, it is best for the elderly and children to add some clothes before opening the window to avoid getting sick due to the sudden drop in temperature after opening the window. If there are serious patients, they should open the window carefully and try to use ultraviolet disinfection lamps to purify the air.
It should be noted that the indoor temperature should not drop below 16℃ due to opening the window, and control it to 16℃— 25℃ is the best.
