Nothing new for the proponents of hygienic theory who have long claimed that the boom in allergies in children, in particular eczema and allergic rhinitis, is caused by too little activation of their immune defenses. To summarize: by using anti-bacterial soaps and using the cleaning wipe all the time, our children are no longer in contact with the bacteria which, however, teach them to defend themselves.
In turn, researchers at the University of San Diego, California, insist on asking parents to “let their children play outside and get dirty.” Not only does this not harm their health but, in addition, it does them good because it allows certain bacteria to “boost” their immune defenses. Thus, when they encounter an allergen, the inflammatory response will be less violent.
