China's traditional Chinese medicine to 

    In jianghan district in wuhan city, hubei province wu today early in the morning came to wuhan respiratory medicine combining traditional Chinese and western medicine hospital, diagnosed as "acute upper respiratory tract infection (commonly known as" cold "). Miss wu wonder, since winter cold weather, plus the city air is bad, in order to avoid a cold, she put on a mask, early commute on the way, there are a lot of people place mask little also not, and daily cleaning, keep health, thought foolproof, unexpectedly still catch a cold. Nowadays, more and more people are wearing surgical masks like miss wu. So, mask can really live bacteria or virus attacks to stop?
 
    There are three kinds of common mask: the first is a medical non-woven masks, the masks generally has three layers, the outside waterproof coating, the middle layer has the effect of adsorption of bacteria, and is close to the skin layer, can have the effect of partial blocking bacteria; The second is the gauze mask, over 6 layer gauze masks, protective effect and surgical masks quite; And the third is a cartoon mask, isolation gauze only 2 layers, it is difficult to have the effect of effective filter, may contain the chemical fiber fabric composition, permeability is bad, in the pigment dye or paint use may contain harmful ingredients, can trigger allergic rhinitis and asthma.
 
    Like miss wu wear face mask instead more easy to catch a cold for a long time. Because covered with human respiratory tract mucous membrane and submucous is full of capillaries, when nose sucked into the cold air, through mucous membrane of nasal die tube heating, humidifying into the lungs, is close to body temperature, physiological function of the body through exercise enhanced, thus improve the ability to keep out the cold.
