After measurement, experts believe the indoor humidity is as follows:

Room Environment: 40～70%RH

The most favorable environment for disease prevention and treatment: 40-55% RH

Library and Cultural Relics Storage Environment: 40～60%RH

Computer and communication equipment storage environment: 45～60%RH

Cotton and woolen textile storage: 40-60% RH

Dairy product storage: 50～60%RH

Candy and pastry storage: 50-60%RH

 Vegetables and fruits storage: 50～70%RH

Grain storage: 50～70%RH

People live on Earth, and they cannot do without the appropriate temperature and humidity. However, they often overlook this most common and extremely important issue that affects their health.

(1) Temperature is inseparable from people's lives. People are constantly seeking or creating temperature in various fields of life.

8～15℃ is the temperature for storing grain, which prevents insects from breeding in the grain. 35～38℃ is the temperature for bath water, as it is close to the body temperature.

 40~45℃ is the temperature of the foot-washing water before going to bed, as this temperature of hot water can promote the dilation of blood vessels in the feet and lower limbs, allowing the brain to rest and helping one to fall asleep.

 70~80℃ is the temperature for boiling water to make tea. Tea brewed with this temperature of water can be said to have a complete blend of color, aroma, and taste. So, what is the temperature inside? It is 18~20℃. This temperature is the average for spring in northern China, which is why there is the idiom "warm as spring."

 When the indoor temperature is this low, people will feel cold hands and feet, work efficiency decreases, or sweat profusely, feeling dizzy. One of the main contents of indoor environment decoration is to use all methods to create or maintain the indoor temperature.

HumidityLooking at our respective families, many have thermometers, but few have humidity gauges hanging on the wall (in fact, there are temperature and humidity recorders sold on the market). This shows that the humidity problem in home interior decoration has not yet received our sufficient attention. In fact, the importance of appropriate humidity to the occupants of a room is no less than that of temperature.

Air humidity refers to the degree of humidity in the air, which can be expressed by relative humidity. Relative humidity refers to the percentage value of the actual density of water vapor in the air and the saturated water vapor density at the same temperature. The relative humidity at which humans feel comfortable indoors is 40%.~70%The relative humidity is either too low or too high, which is uncomfortable and even harmful to the human body.
