What is the most comfortable and suitable temperature and humidity indoor?
When the temperature is 25 ℃, the relative humidity should be controlled at 40 - 50 %. At room temperature 18 ℃, the relative humidity should be controlled at 30 - 40 %.
According to the physiologist study, the indoor temperature is too high, will affect the body temperature regulation function, due to poor heat dissipation, and cause temperature rise, blood vessel relaxation, pulse and heart rate accelerated.
Winter, if the indoor temperature is often maintained at more than 25 ℃, people will be tired, dizziness, brain swelling, mental retardation, poor memory.
At the same time, due to the difference between indoor and outdoor temperature difference, the human body is difficult to adapt, easy to get cold.
If the indoor temperature is too low, it will reduce the human body metabolism function, pulse, respiratory slow, subcutaneous vasoconstriction, skin excessive tension, respiratory tract mucosa resistance weakened, easy to induce respiratory diseases.
Therefore, scientists set the limit temperature of " cold tolerance" and the upper limit temperature of " thermal endurance ", respectively, at 11 ℃ and 32 ℃.
While paying attention to indoor temperature regulation, we should pay attention to indoor humidity.
Summer, when the indoor humidity is too large, will restrain the body heat, make people feel very sultry and agitated.
In winter, when the indoor humidity is large, it will accelerate heat conduction and make people feel cold and depressed.
When indoor humidity is too low, because of the moisture loss of upper respiratory tract mucosa, people will feel thirsty, tongue dry, even throat gall, hoarse voice and nosebleed, and easy to get a cold.
Therefore, experts believe that the relative humidity limit should not exceed 80 %, the lower limit should not be less than 30 %.
However, the somatosensory is not only affected by the two factors of air temperature or air humidity, but the result of the combination of the two.
Through the experiment, the most comfortable indoor temperature and humidity is: winter temperature is 18 to 25 ℃, humidity is 30 % to 80 %;
Summer temperature is 23 to 28 ℃, humidity is 30 % to 60 %.
More than 95 % of people are comfortable in this range.
In the air-conditioned room, room temperature is 19 to 24 ℃, humidity between 40 % to 50 %, the person will feel the most comfortable.
If considering the effect of temperature and humidity on human thinking activities, the most suitable room temperature should be 18 ℃, humidity should be 40 % to 60 %, at this time, people have good mental state, the most agile thinking, and high efficiency.
Suitable temperature and humidity play an important role in the bedroom environment, it directly affects the health of a person, if the temperature and humidity too high or too low will be detrimental to the health of the human body.
Generally speaking, the most comfortable temperature of the human body is 15 - 18 ℃.
If the indoor air is not circulating or relative humidity is less than 35 %, and the indoor temperature exceeds 25 ℃, the body begins to absorb heat from the outside, and you will feel hot.
If the temperature exceeds 35 ℃, the sweat glands of the human body begin to start, and the body temperature, heart rate accelerated, blood circulation accelerated, the blood circulation accelerated, will feel dizzy, whole body discomfort and fatigue, have a feeling of drowsiness, and the heat is unbearable.
On the contrary, when the temperature is below 4 ℃, you will feel cold. When the room temperature is 8 - 18 ℃, the body will radiate heat to the outside, plus indoor breeze circulation, indoor relative humidity between 40 % - 60 %, you will feel comfortable and healthy.
The effect of humidity on the human body is not obvious in the range of indoor comfort temperature.
But at 28 ℃, relative humidity reaches 90 %, you will have a temperature of 34 ℃.
This is because of the high humidity, high moisture content in the air, less evaporation, the large amount of sweat from the body is difficult to evaporate, the body heat cannot be freely distributed, so you will feel hot.
In terms of relative humidity, the most suitable air relative humidity of the body is 40 % - 50 %, because in this range of humidity the bacteria live the shortest life, the human skin will feel comfortable, breathing is normal.
