How much is the right indoor air humidity in the 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.

In autumn and winter, the indoor temperature should be kept between 18 and 25 degrees Celsius, and the humidity should be controlled between 30 and 80 percent. However, in summer, the indoor temperature needs to be controlled between 23 and 28 degrees Celsius, and the humidity needs to be between 30 and 60 percent. The degree of dryness and wetness of the air, or the physical quantity that indicates the amount of water vapor it contains, is called humidity.

The mass of water vapor contained in a unit volume of air is called absolute humidity. Since it is difficult to measure the density of water vapor directly, it is usually expressed as the pressure of water vapor. The absolute humidity of the air does not determine the speed of water vapor above ground and the perception of humidity in people.

The absolute humidity of the air at a certain temperature and the percentage of saturated air pressure at the same temperature are called relative humidity.

When the indoor air humidity standard at home is 30%-60%, and the humidity index is 50%-60%, the human body will feel comfortable. In summer, the relative humidity should be 40%-80%; During winter heating, the humidity can be controlled at 30%-60%; 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%.

You can also place a hygrometer in the room and adjust the humidity in the room at any time through humidity measurement to keep the air in a comfortable range.

Due to the dry air in winter and low humidity, resulting in the breeding and spread of bacteria, 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 and dry, and some effective measures can be taken, such as drinking more boiled water, ventilation, and raising green plants, etc., to increase indoor humidity.

If the indoor dryness is severe, a humidifier can be used to increase the moisture content in the indoor air and increase the humidity in the air.

Hello, the appropriate level of indoor humidity is generally between 40%-60%, which can keep the indoor air humidity appropriate, which is conducive to human health. If the humidity is too high, it will cause more bacteria and viruses in the air, which can easily cause respiratory diseases. If the humidity is too low, the air will dry out, and it will easily cause symptoms such as cough and sore throat. Therefore, the control of indoor humidity is very important, and the indoor humidity can be adjusted by opening windows for ventilation and cleaning the indoor air regularly. Simplified.

The relative humidity of the air at home should be 40%-80%.

Air humidity that is too high or too low can have an uncomfortable effect on the human body. The amount of water vapor dissolved in the air varies with temperature. One cubic meter of air can dissolve 10 grams of water and 30 grams of water.

The maximum absolute humidity is the maximum humidity in the saturated state. Absolute humidity is only meaningful along with temperature, because the amount of humidity that can be contained in the air varies with temperature, and absolute humidity varies from temperature to temperature.

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.
