One of the children’s allergen test results came back today, indicating a severe mold allergy. The child’s mother asked: Where is the mold? Mold may seem impossible to catch, but in fact, it is all around life: the corners of the bathroom, the pillow that may be wet by the child’s sweat, the washer of the drum washing machine (almost all drums have mold), the damp place by the water of the seaside on a trip (usually children with cough and asthma get better once they go to the seaside, and mold allergy is aggravated by going to the seaside), the basement of the home, etc. Children with allergic cough, allergic rhinitis, and asthma need to be actively treated while discovering what the allergens are through allergen testing (allergens can be detected by taking blood tests, skin pricks, etc.). It is not enough to know what the allergen is, finding out where the allergen is and avoiding it is the best way to treat it. Finding where the allergen is is the king of allergy control. Lawn grass goes to seed in the fall, similar to spring pollen. Children chase after grass and inhale tiny particles such as grass seeds, which can easily induce coughing and wheezing. The clinic often encounters children who play on the lawn all afternoon and then come home with a cough. Children with sensitive airways are better off playing on concrete surfaces in the fall when the grass is yellow. Cold air High winds and cool temperatures can easily irritate the respiratory tract and cause coughing. In this case, if you take your child outside, it is best to wear a mask to avoid the direct and strong stimulation of cold air. An ordinary cotton mask can serve this purpose, so you don’t have to wear it all the time after going out, and you can take it off after 5-10 minutes. At the same time, from now on wash your face with cold water in the morning and evening, so that if your child coughs and wheezes, don’t just consider medication, the above factors are examined one by one, and if you can find the factors that cause your child’s allergies and avoid them, you can get twice the result with half the effort.
