What is the best humidity in the room? How much is the right humidity in the room

Indoor humidity of 40%-60% is appropriate. The state has issued indoor air standards, and the relative humidity should be 40%-80% when cooling in summer; In winter, heating should be controlled at 30%-60%. The suitable indoor temperature for the elderly and children is 45%-50%; For patients with respiratory diseases such as asthma, the optimal indoor temperature is between 40% and 50%.

It is difficult to feel the humidity, so it is recommended to have a hygrometer at home so that you can adjust the humidity in the room at any time.

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 the indoor humidity is too high, it will make people feel cold, depressed, and prone to colds, and people live in an environment where the relative humidity is 45%-65% The most comfortable.

Humidity is divided into absolute and relative humidity. Absolute humidity refers to the quality of water vapor per cubic meter of air, relative humidity refers to the degree to which water vapor reaches saturation in the air, 100% RH when saturated, when the absolute humidity is constant, the higher the temperature, the lower the relative humidity, condensation is the phenomenon of condensation on objects with relatively low temperature when the air humidity reaches a certain degree of saturation, humidity is ubiquitous, and condensation is just a special phenomenon where humidity reaches a certain level.

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.

According to China's indoor air standards, the indoor humidity should be 40% to 80% in summer, and 30% to 60% in winter. The suitable indoor humidity for the elderly and children is 45% to 50%, and the suitable indoor humidity for patients with respiratory diseases such as asthma is between 40% and 50%.

In summer, the humidity in most areas of our country is high, so you can place a hygrometer indoors to observe the humidity at any time. The air humidity in the south is high, and the dehumidification function of the air conditioner can be turned on; On rainy days, the outdoor humidity is heavy, so the window opening time should be reduced; When the weather is fine, open more windows for ventilation and moisture; Put some moisture absorbent boxes or desiccants in wardrobes and cupboards; Less fish and a variety of plants in the bedroom.

Extended Information: Methods for Detecting Indoor Humidity Without a Hygrometer:

If you don't have a humidity detector (or a digital thermometer that shows humidity) at home, there's a simple way you can use it. This method does not detect the specific indoor humidity, but it can tell if the air in your home is too dry.

Keep a bottle of water in the refrigerator for a few hours. Then leave it in the room for 5 minutes and condensation will soon appear on the wall of the bottle. Then, if these droplets are about to dry out within 5 minutes, the indoor air is too dry.

If the air humidity is too high, the water droplets can turn into stagnant water underneath the bottle. If the water droplets slide down slowly, the indoor humidity is normal.

The optimal range of indoor humidity varies by region, season, and personal preference, but in general, indoor humidity is between 40% and 60% for comfort and health.

If the indoor humidity is too low (less than 30%), it will cause uncomfortable symptoms such as dryness, dry mouth, cough, and dry eyes. At the same time, too low humidity can easily cause cracking and deformation of furniture, wooden floors and other items.

If the indoor humidity is too high (more than 60%), it will increase the chance of mold and bacteria growth, which can easily cause health problems such as asthma and allergies, and can lead to problems such as dampness in the room and mold on the walls.

Therefore, in order to create a comfortable and healthy indoor environment, it is recommended to keep the indoor humidity in the range of 40% to 60%. Indoor humidity can be controlled through equipment such as air conditioners, humidifiers, or dehumidifiers, or it can be reduced by ventilating, drying laundry, etc.

According to the slag matching experiment, the most pleasant indoor temperature and humidity are: the temperature is 18 to 25 in winter, and the humidity is 30% to 80%; 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 in winter is 30% 60%, the humidity index is 50% 60% of 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 and dry, it is recommended to take some effective measures, such as drinking more boiled water; ventilation; Grow greenery to increase indoor humidity.

In autumn and winter, the indoor temperature should be kept between 18-25 degrees Celsius and the humidity should be controlled between 30-80%. However, in summer, the indoor temperature should be controlled between 23 and 28, and the humidity should be controlled between 30% and 60%. The humidity of the air, or a physical quantity that indicates how much water vapor is contained in the air, is called humidity.

The mass of water vapor contained in a unit volume of air is known as absolute humidity. Because the density of water vapor is difficult to measure 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 on the ground and the perception of humidity by a person.

People call the absolute humidity of the air at a certain temperature and the percentage of saturated air pressure at the same temperature as relative humidity.

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.

The humidity that the human body feels comfortable with is less than 70% relative humidity. The humidity that the human body can adapt to is 30%-80%, but the higher the humidity, the more uncomfortable it may be, affected by the weather temperature, it is generally recommended that the indoor humidity should be lower than 70% in winter.

In autumn and winter and in the room with the air conditioner on, the humidity is usually only 10%-15%rh, and the humidity in such a room is too low, and it will make people feel tight, dry and even hot after staying for a long time. Therefore, in winter, we should pay attention to maintaining indoor humidity, especially in the heated room, to ensure that the relative humidity is 45%-65%rh, and the human body feels the most comfortable within this range of humidity.
