How much is the human feel the most comfortable humidity?

In general, the body feels most comfortable temperature indoors is 15 & ndash; 18 ℃ advisable. If indoor air circulation or relative humidity is less than 35%, and indoor air temperature more than 25 ℃, the body begins to absorb heat from the outside world, you will feel hot. If the temperature above 35 ℃, the body's sweat glands to start at this moment, through the limited capacity slightly sweat accumulated temperature, heart rate, blood circulation acceleration, can feel giddy, whole body discomfort and fatigue, feel sleepy, and extreme heat. On the contrary, when the temperature below 4 ℃,

you feel cold. When the room temperature in 8 & ndash; 18 ℃, the human body will heat to the world, combined with the indoor wind circulation, the indoor relative humidity at 40% & ndash; 60%, you'll feel comfortable and healthy body. The influence of humidity on the human body, within the scope of the indoor comfort temperature is not obvious. But in 28 ℃, relative humidity of 90%, you will feel the temperature reached 34 ℃. This is because when the humidity is big, high content of water vapor in the air, less evaporation, the human body the discharge of a large number of sweat to evaporate, the body cannot be carefree to heat, therefore, you will feel hot. Only from the relative humidity, human body is the most suitable air relative humidity is 40% & ndash; 50%,

in the humidity within the scope of the bacteria in the air the shortest life, human skin will feel comfortable, even normal breathing. According to meteorological experts, when the relative humidity of 30%, the temperature of heat stroke is 38 ℃; When the relative humidity of 80% and the temperature in 31 ℃, physique weaker people sometimes can lead to heat stroke. If in low temperature and humidity weather in winter, people will feel damp cold. Conclusion: health is 45% ~ 65% humidity environment, under the condition of the humidity, the body feel most comfortable, all kinds of germs, not easy to spread. Humidity higher than 65% human body mucous membrane of the respiratory system and causes discomfort, weakened immunity. Placed inside a temperature and humidity meter, can understand the real-time indoor temperature and humidity, to do a good job of humidification or drop wet.
