How much indoor air humidity is good for human health?

Relative humidity less than 30% is considered low air humidity. Low air humidity and low temperature can accelerate the body heat dissipation, at this time the heat radiation in the human body is absorbed by the water vapor in the air, people feel cold, causing capillary constriction, ** pale, human metabolism is reduced, blood circulation and cell metabolism in the tissue disorders, causing tissue nutritional disorders, frostbite. When the indoor relative humidity is less than 10% to 15%, the air is dry, which dehydrates the mucosa of the nasal cavity, trachea and bronchi, reduces elasticity, reduces mucus secretion, weakens ciliary movement, and reduces resistance, so that the inhaled dust bacteria can not be quickly removed from the branches, which is easy to induce and aggravate respiratory diseases.

Dry air can also cause dehydration of epidermal cells, increased keratinization, and decreased sebum secretion, leading to roughness, wrinkling, and cracking. In addition, too dry air will also promote dust and worsen people's living conditions.

In the dry season, the incidence of diphtheria, influenza, whooping cough, meningitis and other diseases also increases significantly, and the number of attacks of asthma and bronchitis increases significantly. The main reason for this is that the dry air accelerates the multiplication of influenza viruses and highly pathogenic gram-positive bacteria, and spreads with the dust, causing epidemics.

When the room temperature is moderate, the change in relative humidity has less effect on the human body. When the temperature is 1 degree, the relative humidity changes by 50%, and the impact on the human body is only equivalent to the indoor temperature change of 1 degree.

"Air humidity" as the name suggests refers to the amount of water vapor contained in the air, the higher the humidity, the more humid the air, and the closer the water vapor is to saturation. Usually we use relative humidity to express the magnitude of air humidity. Under certain temperature conditions, the lower the relative humidity of the air, the faster the human sweat evaporates, and the cooler the human feeling.

The humidity in Beijing is generally about 20 during the day in winter and spring, and about 70 at night, because the humidity in winter and spring is too small, people often have uncomfortable feelings, and sometimes there are dry and chapped lips, nostril bleeding, throat itching and other phenomena. However, in the middle of summer, when the air humidity reaches 80 or more, people will feel unbearable heat due to the slow evaporation of sweat, and sometimes heat stroke may cause diseases such as kidney disease, tuberculosis, and arthritis. The more comfortable meteorological conditions in the living room are:

When the room temperature reaches 25, the relative humidity should be controlled at 40-50, and when the room temperature reaches 18, 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.

Buy a thermohygrometer at the supermarket and have a range on it. This makes it easier to understand and adjust.

1. When the ambient temperature is in.

Baidu18 23°C, relative humidity at 45 Zhi65%RH, is the most suitable indoor humidity for the human body.

dao2, when the temperature is higher than the special.

When it is 35°C and the relative humidity is higher than 70%RH, the self-regulation function of the human body will be relatively weakened.

3. Living in a heated room with a temperature of more than 25, a humidity of less than 30% and poor ventilation for a long time is easy to cause a series of clinical manifestations such as chest tightness and shortness of breath, weakness of limbs, sore throat, and hemoconcentration. Medically, these series of symptoms caused by heating are called "heating syndrome", which is a common disease in winter. The elderly have a slow metabolism and poor body resistance, and are the high-risk people of "heating syndrome", so we should pay special attention to prevention.

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 or mop the floor with a wet mop at home, 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.

According to China's indoor air standard, the humidity in the indoor BAI should be 40% and 80% in summer, and should be controlled at 30% and 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.

The living environment should be 40% 60% Rh, less than 20% RH is dry, and more than 80% RH is wet. The temperature and moderation in the living room can also affect the health of the human body. The optimum temperature in the living room is 25-27 in summer and 18-22 in winter.

The relative humidity is 50%-60% in summer and 45%-65% in winter.

According to physiological studies, too high or too low indoor humidity will have a certain impact on the human body, and it will have a certain impact on indoor air humidity.

The state also has clear standard requirements, in winter when the humidity standard of indoor air should be 30% 60%, and the required humidity.

The degree index is controlled at 50% to 60% as well, and the indoor environment in this range feels very comfortable, which is also required to be the indoor temperature.

The degree should not be higher than 24 degrees.

2.In short, while we pay attention to indoor temperature, indoor humidity is also a key value. During the summer period, if the humidity in the room reaches.

When it is too high, this humidity will inhibit the body's heat dissipation, which will make people feel very irritable and stuffy. And in the winter the humidity is excessive.

, it will cause people to feel cold, depressed, and easy to catch a cold.

3.Pleasant indoor temperature and humidity are: 18 degrees Celsius to 25 degrees Celsius and humidity of 30 to 80 degrees in winter; The temperature in summer is 23 cels.

The degree is 28 degrees Celsius and the humidity is 30 to 60. More than 95 people feel comfortable in this range. In an air-conditioned room.

Inside, the room temperature is 19 degrees Celsius to 24 degrees Celsius and the humidity is 40 to 50 degrees Celsius, which makes people feel very comfortable.

4.High humidity is another issue. When the humidity level exceeds 50% indoors, mold, cockroaches, dust mites and termites can breed.

risk. These problems can also trigger allergies or other diseases. In addition, high humidity can damage electrical equipment such as computers.

Hello dear I am glad to serve you, generally indoor humidity control at 40%-60% is more appropriate. Specifically, it depends on the situation of the sensitive situation. In summer, the indoor humidity can be relatively controlled, and the humidity should be 40%-80%.

In winter, it is controlled at 30%-80%. The suitable indoor temperature for the elderly and children is 45%-50%. Since the humidity is difficult to feel, it is recommended to have a hygrometer at home so that you can adjust the humidity in the room at any time.

How to increase indoor humidity, 1. With the improvement of people's living standards, everyone has higher and higher requirements for the comfort of the space, so it is difficult to accept the dry environment, so the humidifier will be prepared at home, and the humidity will be controlled in a reasonable proportion under the appropriate circumstances, so as to bring a comfortable environment to the living space. 2. Raise plants at home. It is recommended to consider placing green plants in your home that can regulate indoor air, such as pothos, ivy, etc.

Although this kind of plant absorbs a large proportion of water, it also emits a lot of fresh air indoors, and in a dry environment, it can be humidified by these green plants. 3. Consider adding water handicrafts when decorating. For example, fish tanks, etc., can not only decorate the bridge oak, but also increase the humidity in the room, which is a way to kill two birds with one stone.

That's all.

The most adaptable atmospheric humidity for the human body is about 35%-85%, and the most comfortable atmospheric humidity is generally less than 70%. Because the higher the atmospheric humidity, the worse the mood, affected by the weather temperature, in winter, it is recommended that the indoor atmospheric humidity should be lower than 70%.

Because in autumn, winter and summer, most people will turn on the air conditioner at home, the atmospheric humidity is generally relatively low, the humidity is too low, and the time will make it tense, dry, and relatively easy to catch fire.

Therefore, the indoor atmospheric humidity in winter should not be too low, and it is best to keep it above 60%, because in this range of atmospheric humidity, the human body will feel the most comfortable.
