Is indoor humidity 80 harmful to human health in winter?
" air humidity ", by definition, refers to the size of water in the air. The larger the humidity, the more humid air is, the closer the water vapor saturation degree is.
Usually we use relative humidity to indicate the size of the air humidity. Under certain temperature conditions, the smaller the air relative humidity, the faster the human sweat evaporation, the cooler the feeling.
The general humidity of winter and spring in Beijing area is about 20 %, the night is about 70 %, because the humidity is too small in winter and spring, people often have the feeling of not, sometimes appear lips, nose bleeding, throat itching and so on.
However, in the summer season, when the air humidity reaches more than 80 %, because sweat evaporates slowly, people will feel difficult to endure heat, sometimes heat stroke or cause kidney disease, tuberculosis, arthritis and other diseases.
The indoor comfortable weather conditions are: room temperature up to 25 ℃, the relative humidity should be controlled at 40 - 50 %, room temperature up to 18 ℃, the relative humidity should be controlled at 30 - 40 %.
The family with humidifier should pay attention to the indoor humidity often.
