What is the comfortable temperature for human body

Many people do not understand what the comfortable temperature for the human body is. In fact, the most comfortable temperature for the human body indoors is between 15 and 18 degrees. But at the same time, we must also pay attention to air circulation and the relative humidity should be less than 35%.

1. Generally speaking, the most comfortable temperature for the human body indoors is 15-18℃. If the indoor air is not circulating or the relative humidity is less than 35%, and the indoor temperature exceeds 25℃, the human body will begin to absorb heat from the outside, and you will feel hot. If the temperature exceeds 35℃, the sweat glands of the human body will start to activate and dissipate the stored body temperature through sweating. The heartbeat and blood circulation will speed up. You will feel dizzy, unwell and tired, drowsy, and the heat will be unbearable.

2. On the contrary, when the temperature is below 4℃, you will feel cold. When the room temperature is between 8 and 18 degrees Celsius, the human body will dissipate heat to the outside world. Coupled with the indoor breeze blowing and circulation, the indoor relative humidity will be between 40% and 60%, and you will feel comfortable and healthy. The impact of humidity on the human body is not obvious within the comfortable indoor temperature range. But at 28℃ and relative humidity of 90%, you will feel the temperature is 34℃.

3. This is because when the humidity is high, the water vapor content in the air is high and the evaporation amount is small. The large amount of sweat excreted by the human body is difficult to evaporate, and the heat in the body cannot be dissipated smoothly. Therefore, you will feel stuffy. Just speaking from the perspective of relative humidity, the most suitable relative humidity for the human body is 40%-50%, because within this humidity range the lifespan of bacteria in the air is the shortest, human skin will feel comfortable, and breathing will be even and normal.

4. According to statistics from meteorological experts, when the relative humidity reaches 30%, the temperature for heatstroke is 38°C. When the relative humidity reaches 80% and the temperature is 31°C, people with weaker constitutions may sometimes suffer from heatstroke. If there is low temperature and high humidity in winter, people will feel damp and cold.

5. A healthy humidity environment is 45% to 65%. Under such humidity conditions, the human body feels most comfortable and various germs are not easily spread. Humidity above 65% can cause discomfort to the human respiratory system and mucous membranes, and reduce immunity.
