What is the best indoor air humidity in summer?

The average person feels most comfortable at 45-55% relative humidity. In summer, the temperature is high, and humidification should be taken care of.

Finally, aloe vera is also a very good choice, because aloe vera is not only a beauty but also a very good detoxification plant. Moreover, aloe vera is very suitable for growing in autumn and winter, especially in dry environments, and its vitality is particularly tenacious, relatively easy to feed, and it is the best choice for most families.

If the room is drier, adjust the humidity by 40% to 70%, and if the room is wet, you can adjust it to 40% to 60%, and the more comfortable humidity is 50% to 60%.

The relative humidity should be 40% to 80% for cooling in summer, and 30% to 60% for heating in winter.

1. The humidity of the room is 85. In summer, the indoor humidity is generally 40% to 80%, and in winter, the indoor humidity should be controlled at 30% to 60%. If the indoor humidity exceeds 80%, the water vapor content in the air is relatively high, and the heat of the human body cannot be quickly dissipated, which is easy to cause discomfort to the human body.

2. Humidity is a physical quantity that indicates the degree of dryness of the atmosphere, which generally refers to air humidity in meteorology, mainly referring to the content of water vapor in the air.

3. Under suitable temperature conditions, the less water vapor is contained in a certain volume of air, the drier the air, and the more water vapor is contained, the more humid the air is.

4. If the home is damp, you can place a dehumidifier or dehumidifier indoors, or adjust the air conditioner at home to the dehumidification function, which can help the room become dry to a certain extent.

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.

If it is autumn or winter, the indoor temperature should be kept at 18-25 degrees Celsius.

The humidity is 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 put the absolute humidity of the air at a certain temperature and the saturation pressure at the same temperature.

The percentage is called the 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.

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.

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.

4% to 8%.

In 23 years, the state issued indoor air standards, and the relative humidity should be 4%-8% when cooling in summer; In winter, heating should be controlled at 3%-6%. The suitable indoor temperature for the elderly and children is 45%-5%; For patients with respiratory diseases such as asthma, the optimal indoor temperature is between 4% and 5%.

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

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.
