1, the most suitable air relative humidity for human body is 40%-50%, because the life span of bacteria in the air is the shortest in this humidity range, and human skin will feel comfortable and breathe evenly and normally.

2. At a certain temperature, the less water vapor is contained in a certain volume of air, the drier the air is; The more water vapor, the wetter the air.

3. In this sense, absolute humidity, relative humidity, mixing ratio, saturation deficit, dew point and other physical quantities are commonly used to express; If the weight of liquid water in wet steam accounts for the percentage of the total weight of steam, it is called the humidity of steam.

4. In the comfortable indoor temperature range, the influence of humidity on human body is not obvious. But when the temperature is 28℃ and the relative humidity reaches 90%, you will feel the temperature reaches 34℃. This is because when the humidity is high, the water vapor content in the air is high and the evaporation capacity is low, so it is difficult to evaporate a large amount of sweat discharged by the human body and the heat in the body cannot be dissipated smoothly.

Extended data:

When the temperature is too high in summer, hot flashes on the body surface will make people fidgety and insomnia. Too cold in winter can make people nervous and lead to insomnia. Studies have shown that people are in an environment of 2 1℃ to 24℃, which makes them feel comfortable and more conducive to sleep. The theory of TCM health care points out: "The room you live in must always be elegant and tidy, while it is empty in summer and warm and dense in winter. So resting at constant temperature is a good way to sleep and keep fit.

Fresh air helps to improve the quality of sleep. The air in the bedroom should be kept unobstructed as far as possible, because it is easy to produce peculiar smell, sultry feeling and even reduce the indoor oxygen concentration, which makes people feel uncomfortable. Opening windows to generate air convection or using air purifiers to keep indoor air clean is absolutely helpful to improve sleep quality. Especially for patients with respiratory problems, the author suggests that more attention should be paid to the unobstructed air in the sleeping environment.

People's Network-Bedroom temperature and humidity affect the quality of sleep, and the environment is not insomnia.
