Winter air humidity is not ignored
In winter, the air is relatively dry, and the average relative humidity during the day is generally lower than 50%. In addition, the climate is cold and indoor heating, and the indoor humidity is often only about 30%. If the humidity is too low, it will evaporate. The dry air will easily take away water from the body, causing irritation to the oral and nasal mucosa, and symptoms such as dry cough, hoarseness and sore throat. When dry cold air enters in winter, it can easily induce pharyngitis and trachea. Inflammation, pneumonia and other illnesses.
The most suitable air relative humidity for the human body is generally between 40% and 65%. Too dry or too humid environment, the body will not adapt. At the same time, microorganisms floating in the air and scattered on the surface of the object are always an integral whole with water. Once the temperature and humidity are appropriate, it will grow and multiply. If the humidity is too high, the increase of water in the air, plus the appropriate temperature, some mold, bacteria, actinomycetes, etc. will have germination, invasion of the human body. Therefore, in the winter we need to reasonably maintain the indoor air humidity.
The use of a humidifier is one of the common choices for people, but the following issues need attention:
Pay attention to maintain the indoor humidity: indoor humidity can be 40% to 65% can, and pay attention to window ventilation, and conditions can buy a hygrometer, when the appropriate humidity stops humidifying.
Humidifier use time should not be too long: the elderly, pregnant women, children's respiratory mucosa is relatively fragile, long hours to open the humidifier, will accelerate the spread and reproduction of some bacteria, as the aerosol diffuses into the air, and then enter the human respiratory tract , it is easy to cause respiratory diseases. Therefore, it can be turned off in 2 to 3 hours, and it does not need to be open all day long.
Do not add bactericides, perfumes, essential oils, etc. arbitrarily: Because the contained bactericides, fragrances, and preservatives are inhaled into the air after being atomized, they can cause irritation to the lung and bronchial epithelial cells, causing Different degrees of illness.
Humidifier water should not be directly used in tap water: tap water generally contains some metal ions, such as magnesium ions, calcium ions, etc., not only pollute indoor air, but also may induce asthma, bronchitis, pneumonia and other diseases. Therefore, the office uses a humidifier, it is best to add pure water; use a humidifier at home, in order to save costs, you can boil the tap water, and then cool to about 40 °C and then add the humidifier.
Pay attention to cleaning the humidifier: to avoid breeding bacteria, it is best to change the water every day, thoroughly clean once every two weeks.
In addition to using a humidifier, hanging a wet towel in the room or sprinkle some water in the corner can also increase the humidity of the room. At the same time, when you have to open the humidifier often, pay attention to eating more fruits at the same time. In this way, winter can be more comfortable.
