What is the optimal air humidity in winter

The temperature in winter is very humid. In the cold winter, many people are concerned about whether the temperature at home is enough. However, if the temperature at home is too high with heating, it is very uncomfortable for people to stay in the room. They often get angry. Getting angry will not only cause constipation and oral ulcers, but also it is easy to catch a cold when going out if the temperature in the house is not too high. This can be seen from the air humidity in winter, so what is the best air humidity in winter?

In cold seasons, people are most concerned about whether the temperature at home is sufficient. However, a room with too high a temperature makes people feel uncomfortable, which often "adds fuel to the fire". This is why people often say that the humidity is not enough.

Scientific research shows that people feel most comfortable and are less likely to develop respiratory diseases in an environment with a relative humidity of 45-65% RH and a humidity index of 50-60. The indoor humidity during the winter heating period in northern my country is usually 15% RH. In this dry environment, people generally feel various discomforts.

When the air humidity is lower than 40% RH, the movement of cilia on the human nose and lung respiratory mucosa slows down, and dust, bacteria, etc. are easily attached to the mucosa, irritating the throat and causing symptoms such as thirst, dry cough, hoarseness, and sore throat.

It also speeds up the reproduction of influenza viruses and Gram-positive bacteria that can cause infection, and can easily spread with dust in the air, causing other diseases.

Therefore, when dry and cold air invades in autumn and winter, it can easily induce pharyngitis, tracheitis, pneumonia and other diseases. In addition, allergic diseases such as allergic dermatitis, bronchial asthma, and skin itching are also related to dry air.

When the air humidity is greater than 65% RH, the amount of pineal hormone in the human body is also large, which makes the concentration of thyroid hormone and adrenaline in the body relatively lower, and people will feel listless and depressed. Working and living in a humid environment for a long time can easily lead to rheumatic diseases, rheumatoid arthritis and other rheumatism diseases, which will eventually lead to a decrease in the body's immunity.

In fact, moderation is indispensable in people's lives. If the air humidity is too low in winter, the human body will feel uncomfortable and the respiratory system will be obstructed, especially in the winter in northern my country. Every household has heating, the house is very dry and the outside is very humid. If it affects the body, you can use a humidifier or mop the floor to increase the humidity in the house, which will help prevent dryness and heat.
