Mold is a type of fungus that tends to grow in warm, humid environments, is extremely prolific, and is almost ubiquitous. Although we say that it is very difficult to avoid exposure to mold, and although we have many kinds of medications to treat allergy symptoms, it makes sense to minimize exposure to mold for patients with a clear history of mold allergy. Preventive measures include: 1, can not eat and smell the food containing mold: cheese, mushrooms (mushrooms, fungus, etc.), pickled food (pickles, etc.), food made from yeast or yeast powder (such as bread, canned juice, buns, etc.). 2, do not keep flowers and pets in the house, do not put carpets, babies do not play with stuffed toys, bedding, pillows regularly clean, keep dry, try to close the doors and windows in the late summer and early autumn season (because it is the season when outdoor mold grows the most), indoor air conditioning with air filters can be used to adjust the temperature and humidity. Try to reduce outdoor activities in such seasons, and bring a mask if necessary. 3, mold is easy to grow in the humid environment inside the house, commonly found in closets, storage rooms, lower drawers, carpets, garbage cans, bathrooms, sinks, dead ends of refrigerators, you can use chlorine bleach to regularly clean bathrooms, cabinets and other places, to keep the house dry, dehumidifiers can control the humidity in the house. 4, do not easily apply antibiotics and certain Chinese medicines (such as poria, ergot, etc.), it is recommended that allergic babies do not eat raw even if not detected allergic food, such as whipped cream on cake, raw seafood, etc., boiled or fried food is safer.
