The most important way to take care of a child with asthma is for parents to know the causes and patterns of their child’s asthma. For example, what allergens develop after exposure to them, what seasons they develop, what temperatures and air pressure they develop, etc. Once these rules are mastered, they can try to avoid or reduce their child’s exposure to these environmental factors. So, how can parents take good care of their asthmatic children? Record the date, time, place and severity of each asthma attack, the weather conditions on the day of the attack, any special diet and exposure to special chemicals, medication, and any special events that happened in the child’s life the day before the attack, such as whether the child had strenuous exercise, cries Laughter or mood swings, etc. The environment and living conditions on days when there is no asthma attack should also be carefully analyzed and recorded. After a long period of patient and careful observation, analysis and generalization, the suspected factors related to the attack can be identified and measures can be taken to avoid them. (1) Choose a sunny room, keep it clean, ventilated and dry, and forbid parents to smoke; (2) All bedding should be made of cotton, not bedding made of fur, silk, cotton or down, etc. Pillow inserts made of foam are better, and parents should not open cotton clothes, quilts or woolen clothes and pants in front of children; (3) Do not keep cats, dogs, rabbits, pigeons, etc. at home. (4) Parents should not use strongly scented cosmetics, and should not apply cosmetics to their children, and all chemicals with strong odors, such as paint, dichlorvos, gasoline, etc., should not be placed in places where children often go out; (5) Children’s toys should be odorless wood, cloth, metal or plastic products, and toys made of fur or thick velvet or toys with special odors should not be used. (6) Pay attention to the child’s diet. If the child is found to have an asthma attack after eating a certain food, he/she should stop eating that food immediately; (7) If the child has acid reflux in the esophagus, it is recommended to eat less and more meals. (1) Eat, sleep, and urinate and defecate regularly; (2) Do not eat too much and do not eat foods with strong stimulating properties (such as chili peppers and overly acidic, salty, and sweet foods); (3) Allow the child to have some outdoor activities every day. The time and content of the activity can be flexible according to the age and the degree of smooth breathing. Do not overly restrict your child’s physical activity for fear of an asthma attack, but if your child has seasonal asthma attacks, then reduce outdoor activities during the asthma attack season. 4. Pay attention to monitoring your child’s asthma aura Children with asthma often have aura before an asthma attack, such as continuous sneezing, constant coughing, irritability, mental agitation, and rapid breathing. It is best to monitor asthma attacks with a peak expiratory velocity meter and use asthma calming medication in time to prevent a major asthma attack once an asthma aura appears.
