It's the season for respiratory infections. After experiencing one, two, or even three yang, many people find that their resistance has become worse, and as long as the people around them have the flu, they can't escape this catastrophe (I don't know if it's a psychological effect or a fact). The same is true for the children in the school, every day in each class there are people in each class who ask for leave because of colds, fevers and other respiratory diseases, and some classes are even "wiped out", which makes a group of parents and teachers feel distressed and sigh.
The reason why it is easy to catch a cold in winter is not only because of the low temperature, but also because the air is too dry, and the virus is more likely to spread and invade the human body.

% relative humidity can greatly reduce respiratory disease infections
Dr. Stephanie Taylor of the Center for Infection Control at Harvard Medical School has called on the World Health Organization to assess the correlation between humidity and health, providing experimental evidence and recommending that the ideal indoor relative humidity should be maintained at 40-60%. This humidity range is effective in reducing the transmissibility of indoor respiratory diseases, such as the novel coronavirus and influenza.
If the indoor relative humidity is too low, the infection rate of respiratory diseases will be greatly increased in indoor places such as offices, schools, hospitals, shopping malls, restaurants, etc., where people gather for a long time.
The authoritative British magazine noted
The lower the humidity, the greater the risk of infection from the new coronavirus
According to a study in the British journal Transboundary and Emergingdiseases, the spread of the novel coronavirus is related to the humidity of the air, and the lower the humidity and the drier the air, the greater the risk of infection.
Australian and Chinese researchers found
A 1% decrease in humidity will increase the number of confirmed cases of the novel coronavirus by 7-8%.
Australian and Chinese researchers found that a 1% drop in humidity was associated with a 7-8% increase in confirmed cases of the novel coronavirus, because dry air is conducive to the long-term suspension and survival of virus droplets, and is more likely to adhere to people, resulting in a relatively higher chance of infection.
In addition, in an environment with humidity below 40%, the body's respiratory immune system defense function will also be affected, making it more susceptible to viral infection. In an environment with a humidity of 40-60% that the human body feels comfortable with, the respiratory immune system function in the human body can be more effective. At the same time, the moisture will envelop the virus and sink, so that the virus can survive and suspend for a shorter time, and it is not easy to adhere to the human body, and it is not easy to be sucked into the mouth and nose.
Indoor humidity is so important, so how do you maintain it?
In order to reduce respiratory infections more effectively, there are various ways to maintain indoor humidity:
1. Use a humidifier
Recommend Runliqi air purifying humidifier, which has an automatic humidification feedback mechanism to keep the indoor humidity at 40 70%, if the humidity exceeds 70%, it will automatically stop humidifying, and if the humidity is less than 40%, it will continue to humidify. Moreover, Runliqi is fog-free humidification, which will not produce fog visible to the naked eye, and will not wet the wet floor. The inside of the humidifier can be automatically cleaned, and secondary pollution caused by inadequate cleaning can also be avoided.
In addition to humidification, it also has a purification function, which can effectively remove various viruses, bacteria, formaldehyde, and PM2 in the air5 and other harmful substances to ensure that the air released is clean, healthy and moist.
Runliqi has a very good reputation in Japan, and many hospitals, schools, nursing homes, offices, etc. are using it, and the Japanese are relatively not very popular with winter flu, among which Runliqi has also made a great contribution.
If you want to use a humidifier during the months when the flu is frequent in autumn and winter, then it is highly recommended to use the Runrich air purifying humidifier in the form of a rental. The monthly rental cost of each unit is only 600 yuan, with a triple filter, official door-to-door maintenance, and no other**consumption.
Renting Runliqi is a highly recommended way to maintain 40-60% relative humidity for the room, as long as one machine can ensure the indoor relative humidity, which is very cost-effective.
2. Plant broad-leaved plants
The leaves of plants emit water vapor, and the wide leaves emit more water and are more likely to increase the humidity in the room. In addition, leafy green plants also emit oxygen ions, which can also help improve air quality.
However, the humidification capacity of green plants is limited, and it is difficult to achieve a relative humidity of 40 to 60% by means of green plants alone. Only as an adjunct.
3. Wipe with a damp cloth
Wet cloth wiping and placing a basin of water is the same reason, in order to speed up the evaporation of water, but like green plants, humidification efficiency is limited, only by wiping, can improve the cleanliness of indoor hygiene, but only by wiping to meet the humidity requirements, less likely.
4. Manual sprayer
Not highly recommended, manual spraying, while simple and easy, also has safety implications. First of all, the humidification is uneven, it is likely that some places are overhumidified, and some places are not humid enough, and excessive humidification, such as more than 70% humidity, may breed mold viruses, and at the same time, if the sprayer sprays tap water directly, if it is not cleaned in time, the internal components have been in a humid state, and it is easy to produce various molds, which are sprayed in the air with the secondary spray, causing secondary pollution.
Either way, it is important not to increase the indoor humidity excessively at once, which can lead to moisture, mold and longwall cancer on walls and windows, etc. It is recommended to use a hygrometer to test the relative humidity in the room (Runrich comes with a humidity meter) and try to maintain it at a suitable relative humidity.
