What is the most suitable temperature for living?

The most suitable temperature for human habitation is 15- 18℃ and the humidity is 78%-85%. The details are as follows: Generally speaking, the most comfortable indoor temperature for human body is 15- 18℃. If the room is not ventilated or the relative humidity is less than 35%, the indoor temperature will exceed 25%. You will feel hot. If the temperature exceeds 35℃, the sweat glands of the human body will start at this time, accumulate body temperature through slight sweating, accelerate the heartbeat and accelerate the blood circulation. You will feel dizzy, unwell, tired and sleepy, and it will be extremely hot. Conversely, when the temperature is below 4℃, you will feel cold. When the room temperature is 8- 18 and the indoor relative humidity is between 40% and 60%, you will feel comfortable and healthy. In the comfortable indoor temperature range, the influence of humidity on human body is not obvious. But when the relative humidity reaches 90% at 28℃, 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. You will feel sultry. Just from the perspective of relative humidity, the most suitable air relative humidity for human body is 40%-50%, because in this humidity range, bacteria in the air have the shortest life, and human skin will feel comfortable and breathe evenly and normally. According to the statistics of meteorologists, when the relative humidity reaches 30%, the temperature of heatstroke is 38℃, and when the relative humidity reaches 80%, the temperature is 365,438+0℃, and the body will be healthy. If we encounter low temperature and high humidity in winter, people will feel wet and cold. Healthy humidity environment is 45% ~ 65%. Under such humidity conditions, people feel most comfortable, and various germs are not easy to spread. If the humidity is higher than 65%, people will feel uncomfortable in the respiratory system and mucous membranes, and their immunity will decrease.
