Wang Jian, chief physician of the respiratory department of Shanghai Ninth People’s Hospital, said: winter is a season of high incidence of respiratory diseases. With the decrease of outdoor temperature, more and more people use humidifiers at home. But not all humidifiers are healthy. Because the white mist produced by the humidifier is produced by the minerals in the water ejected with the water mist, these mineral containing white mists have a strong adsorption capacity, and will adsorb the dust, bacteria, viruses, decoration and other residual toxic pollutants in the air. Especially in the case of poor air quality, there are many tiny particles in the air, which are easy to stimulate the trachea and bronchial mucosa after being adsorbed by the white mist, causing a variety of respiratory system diseases.
Wang Jian said that the respiratory mucosa of the elderly, pregnant women and children is relatively fragile. If the humidifier is turned on for a long time, the white fog will accelerate the spread and reproduction of some bacteria. As the mist spreads into the air and enters the human respiratory tract, it is easy to cause respiratory diseases such as bronchitis, asthma and even pneumonia.
In addition, some people like to add fungicides, essential oils and other materials to humidifiers, thinking that this can strengthen the role of sterilization and influenza prevention. But in fact, the liquefaction process of these additives will further aggravate the formation of white fog, and the fungicides have strong irritation, which will further damage the airway mucosa and seriously harm our bodies.
The doctor warned that the use of humidifiers can indeed alleviate the indoor drying problem in winter, but it is not that the more white fog the better. It is forbidden to equate “white fog” with “good humidity”.
