How much is the indoor air humidity good How much is the indoor air humidity at home

As long as it is not lower than 5% RH (relative humidity) or higher than 95% RH, the average human body can tolerate it well.

The impact on human health is mainly long-term exposure to low temperature and high humidity environment, and the human body will be susceptible to certain joint diseases and ** diseases. Other environments do not have much of an impact on health.

It is not advisable to stay in a place with too high humidity for a long time, because it is easy to suffer from arthritis and other diseases in this environment for a long time. The long-term low humidity environment will make the ** rough and cracked, but there will be no serious diseases. However, from the perspective of human body sensation, it is related to temperature.

Those of the following may make you feel comfortable.

0 below 8, low atmospheric humidity is better, 20%RH 50%RH is appropriate, will make you feel not too cold, but ** easy to lose water. If the humidity is high, it will feel cloudy and cold.

8 28 , as long as 30% 80%, the human body is acceptable. About 50% RH is more appropriate. If the humidity is low, it will feel dry, and if the humidity is too high, it will feel damp.

Above 28, the humidity decreases with the increase of temperature, which is conducive to human perspiration and heat dissipation. If the humidity is too low, it will be very dry, and it will quickly make the water loss rough, and the humidity will make people feel stuffy, making it difficult to sweat.

According to physiologists, when the indoor temperature is too high, it will affect the body's thermoregulatory function. In winter, if the indoor temperature is constantly above 23 degrees Celsius, people will be tired and dizzy. At the same time, due to the huge temperature difference between indoor and outdoor, it is difficult for the human body to adapt and it is easy to suffer from colds and flu.

If the indoor temperature is too low, it will reduce the metabolic function of the human body, slow down the pulse and breathing, weaken the resistance of the respiratory mucosa, and easily induce respiratory diseases. While paying attention to the indoor temperature regulation, you should also pay attention to the indoor humidity. In summer, when the indoor humidity is too high, it will inhibit the heat dissipation of the human body, making people feel very hot and irritable.

In winter, when there is high humidity in the room, it can make people feel cold, depressed, and prone to colds. The most pleasant indoor temperature and humidity are: 18 degrees Celsius to 25 degrees Celsius in winter, and humidity 30 to 80; In summer, the temperature ranges from 23 to 28 degrees Celsius and the humidity ranges from 30 to 60.

1. If it is winter, the most comfortable indoor humidity is 30% to 80%, and the temperature is 18 to 25, if it is summer, the most comfortable indoor temperature is 30% to 60%, and the temperature is between 23 and 28; When the air conditioner is turned on, the humidity is between 40% and 50%, which makes people feel more comfortable.

2. If the indoor humidity drops significantly, you can turn on the humidifier, which not only has a good humidification effect, but also is very convenient to use. However, when choosing a humidifier, you need to choose according to the size of the room, if the area of the room is about 30 square meters, you should use a humidifier of 400 ml for an hour.

The suitable temperature of the room is 18-20 degrees Celsius and the humidity is 55%-60%.

WHO stipulates that the sixth standard of healthy housing is to maintain indoor humidity between 40% and 70% throughout the year.

Air humidity is the degree of dryness and wetness of the air, which is expressed as a percentage as the ratio of the actual water vapor pressure in the atmosphere to the saturated water vapor pressure at the same temperature. When the relative humidity is 40% to 70%, the human body feels the most comfortable and is not prone to disease.

If the indoor humidity is too high, the human cells will be "passive and slack", causing nausea, constipation, loss of appetite, irritability, tiredness, dizziness and other symptoms. Living in a place with high humidity for a long time is also prone to rheumatoid arthritis and other dampness.

The state has issued and implemented indoor air standards, and the relative humidity should be 40%-80% for cooling in summer, and 30%-60% for heating in winter. The suitable indoor humidity for the elderly and children is 45%-50%, and the suitable indoor humidity for patients with respiratory diseases such as asthma is between 40%-50%. It is difficult to feel the humidity specifically, so it is recommended to have a hygrometer at home to adjust the humidity in the room at any time.

Extended information: According to physiologists, human comfort is the result of a combination of temperature and humidity.

While paying attention to the temperature, you should also pay attention to regulating the indoor humidity. In summer, when the indoor humidity is too high, it will inhibit the heat dissipation of the human body, making people feel stuffy and irritable; In winter, when the indoor humidity is too high, it will accelerate the heat conduction, making people feel cold and depressed.

Room temperature up.

, the relative humidity should be controlled.

40-50 is appropriate, room temperature up.

, the relative humidity should be controlled at 30-40. Households with humidifiers should take care to adjust the indoor humidity frequently so that it can adequately serve your health.

In an environment with a relative humidity of 45% to 65% rh, the human body feels most comfortable. During the winter heating period, the indoor humidity is usually only 15%RH. You can use a humidifier at home or mop the floor with a wet mop, or place a basin on the heater.

Keeping two pots of daffodils in the living room can regulate the relative humidity of the room and fill the room with fragrance.

Hello, through experimental measurements, the most pleasant indoor temperature and humidity are: 18 to 25 in winter, 30% to 80% humidity; In summer, the temperature is 23 to 28 and the humidity is 30 to 60 percent. More than 95% of people feel comfortable in this range.

People will feel most comfortable in an air-conditioned room with a room temperature of 19 to 24 and a humidity of 40 to 50 percent. If the influence of temperature and humidity on people's thinking activities is taken into account, the most suitable room temperature should be high work efficiency. 18. The humidity should be 40% to 60%, at this time, people's mental state is good, and their thinking is the most agile.

According to the requirements of the national indoor air quality standards: the indoor air humidity standard is 30% 60% in winter, the humidity index is 50% 60% The environment is the most comfortable, and the indoor temperature should not be higher than 24 degrees.

Due to the dry air and low humidity in winter, which leads to the breeding and spread of germs, coupled with the use of heating and air conditioning, the humidity in the indoor environment is often low, which is easy to make people nervous, dry and hot, it is recommended to take some effective measures, such as drinking more boiled water; ventilation; Grow greenery to increase indoor humidity.
