Cough variant asthma (CVA for short) is a specific type of asthma with chronic cough as the main or only clinical manifestation. Cough variant asthma is one of the common respiratory diseases in children for which antibiotic therapy is ineffective and anti-asthma therapy is effective. Parents should pay enough attention to cough variant asthma, especially for frequent attacks and poorly controlled CVA. what kind of home management should be done for cough variant asthma? 1. When the seasons change and the temperature changes suddenly, parents should keep their children warm to avoid getting cold and flu. Ensure a relatively suitable indoor temperature and humidity and avoid convective winds. 2. Avoid foods that can aggravate the cough, such as cold drinks, overly sweet and salty foods, carbonated drinks and foods that have caused allergies. 3. Don’t keep pets or flowers at home, and don’t lay carpets to avoid children’s exposure to pollen, dust mites, oil fumes and paint. 4, in the bathroom or basement should use dehumidification equipment and air filters, and regularly replace the filters to avoid the growth of mold. 5.Pillowcases, clothes and bedding should be washed and changed regularly to assist in removing dust mites and their metabolites, and placed in the sun to dry for a long time. 6.When the cooler is taken out for use in the second summer, it should not just be scrubbed with a wet cloth, but soaked in boiling water for 2-3 hours and then placed in the sun to completely kill the mites. 7, uncontrolled cough variant asthma children’s lungs are susceptible to viruses, bacteria and other attacks, should be treated in a timely manner, otherwise it will cause long-term persistent damage to the human respiratory system, triggering more serious cough lung disease, and lead to a vicious cycle. 8. Combine prevention and treatment with physical fitness – appropriate physical exercise can promote better adaptation of the respiratory system to the surrounding environment to avoid recurrence of the disease. Winter is a vulnerable period for pediatric cough, in which cough variant asthma causes one of the common causes of cough. Repeated coughing affects the physical and mental health of children and their families, requiring standardized treatment under the guidance of a doctor and, more importantly, a scientific and standardized family management. We hope that some of the common sense of daily management introduced above will be helpful to you.
