1. Control dust mites. “Mite” is the culprit that triggers asthma triggers in some children. The best bed for children with impermeable bed cover to wrap the mattress, pillows or wash the pillowcase weekly; use 55 ℃ water to wash the bedding weekly; avoid sleeping or lying flat on the fiber textile wrapped furniture; remove the indoor carpet; indoor humidity less than 50%; use chemicals (insecticide) to kill mites or change the indoor mite antigens. 2.Remove animal allergens. Because the dander, urine and saliva produced by rodents and birds can cause allergic reactions. Avoid staying around woods and parks for a long time. 3.Avoid foods that cause asthma. When your child has an asthma attack, you should avoid fishy foods and other hairy items, and focus on a light diet, and then make dietary supplements during the remission period according to the child’s physical condition, and usually try to avoid cold drinks. The mother of the affected child should advise her child what forbidden foods to pay attention to when eating at school. 4, control air pollution. Such as tobacco, aerosol, play organic compounds (polish, paint, etc.), instruct the child to try not to poplar, willow, pine, cypress, acacia, birch and other trees with a lot of pollen, do not stop in public places for a long time. 5. Avoid taking drugs that aggravate asthma. Such as aspirin, ibuprofen, etc. Tell the life teacher that your child has asthma. 6. Strengthen physical exercise. Because some children’s symptoms worsen after exercise, parents do not have confidence in their children’s participation in sports. Therefore, parents are prone to dispel ideological concerns and assist their children in choosing appropriate sports and gradually increase the amount of exercise to enhance physical fitness and reduce respiratory tract infections. However, exercise should not be strenuous to avoid triggering asthma attacks.
