How much is the indoor humidity in winter? The best way to increase indoor humidity
4hw.com.cn: China's winter weather is cold and dry. After staying indoors for a long time, my mouth and nose are dry. Many students put one humidifier at home. How much is the best indoor humidity in winter? In addition to humidifier, how to increase indoor humidity? Let's take a look with Xiaobian.
How much indoor humidity is appropriate in winter
The humidity that the human body feels comfortable is: the relative humidity is less than 70%.
Theoretically, the humidity that the human body can adapt to is 30% - 80%, but the higher the humidity, the more uncomfortable it may feel. Affected by the weather and temperature, it is generally recommended that the indoor humidity should be less than 70% in winter.
In autumn and winter and in the air-conditioned room, the humidity is usually only 10% - 15% RH. If the humidity in such a room is too low, people's skin will be tight, dry and even get angry after staying for a long time. Therefore, pay attention to maintaining indoor humidity in winter, especially in rooms with heating turned on, and ensure that the relative humidity is 45% - 65% RH. Within this range, the human body feels most comfortable.
Appropriate humidity can greatly improve human comfort
Only in terms of relative humidity, the most suitable air relative humidity for human body is 40% - 50%, because within this humidity range, the life of bacteria in the air is the shortest, human skin will feel comfortable and breathe evenly and normally.
The humidity is very high. Even in the environment with low temperature, for example, when the relative humidity reaches 90% at 28 ℃, the human body will feel that the temperature reaches 34 ℃. This is because when the humidity is high, the water vapor content in the air is high and the evaporation is low. A large amount of sweat excreted by the human body is difficult to evaporate, and the heat in the body cannot be dissipated smoothly, so it will feel muggy.
How should indoor humidity be increased
Use humidifier
Humidifier is not a very expensive electrical appliance, and the size of humidifier should be determined according to the indoor area. For example, an indoor area of 30 square meters is more suitable for a humidifier of 400ml per hour, and an indoor area of 50 square meters is more suitable for a humidifier of 500ml per hour, which basically means 1m2: 10ml per hour.
Place green plants
Where there are many plants, there is more water. Therefore, more green plants can be planted in winter. Planting green plants that can be placed indoors can not only purify the air, but also increase the air humidity. For example, Anthurium andraeanum, green pineapple, iron tree, yiyelan, etc. are placed in every corner of the room to make the indoor humidity relatively average and pay attention to mosquito prevention.
Sprinkle water on the ground
In northern families with floor heating, the air humidity is often relatively low, which will make people feel dry and uncomfortable. You can sprinkle a little water on the floor every day, or drag the floor twice with a wet mop, which can also alleviate the indoor dryness.
Put a basin of water
This is the easiest way to increase air humidity. If you put a basin of water indoors, the heat of air conditioning and floor heating will accelerate the evaporation of water and let the water vapor radiate into the air, you can increase the air humidity. Use a towel, half in the water and half in the air, so that the humidification effect will be better.
Pay attention to indoor ventilation in winter
Although the weather is cold, many people may have closed doors and windows at home, which is not good for their health. The bacteria they breathe gather in the house and cannot be discharged. Therefore, in winter, it is better to ensure the ventilation of doors and windows twice a day. It is more appropriate to open windows around 10 a.m. and 4 p.m. for ventilation. A sun has just come out, A sun will disappear soon, and the air will be warmer and wetter, which is suitable for indoor air replacement.
Pay attention to replenishing water in winter
The air is dry in winter. No matter whether the heating equipment such as air conditioning and floor heating are turned on or not, we should also pay attention to the replenishment of water in the skin and body, otherwise it is easy to be dry due to water shortage. Pay attention to skin maintenance, often wipe moisturizing lotion, and drink more water to increase the amount of drinking water, which can effectively prevent dryness.
