What worries parents is a cough that lasts for a month, or a cough that comes back just two days later. The words I hear over and over again in the clinic are: “Doctor, here we go again. What makes a cough so bad and so unrelenting? How can we solve each dilemma? Repeated respiratory infections are the most common cause of recurrent coughs. In autumn and winter, the dry, cold air reduces the body’s ability to fight disease in the respiratory tract, so respiratory infections begin to increase. And as the number of people with respiratory infections increases, so do the sources of infection and the chances of cross-infection. There are often children who have a cold and cough and then start coughing again in less than a week after being sent to kindergarten. This is because the child’s immune system is weak when the illness is just over, and many of the children go to kindergarten with the illness, causing cross-infection and coughing again. There are also children who have just recovered and whose mothers take them to crowded places such as shopping malls, movie theaters, and restaurants, where there is no good ventilation, but the population is dense and the sick people are mixed in with them, resulting in re-infection and coughing again. There are also children who are recovering from a minor illness and want to eat delicious food, to eat continuously delicious food, eat a few days, the stool does not pass, accumulation of food on fire, and fever and cough. How to avoid the occurrence of: respiratory infections are not very realistic to avoid completely, but pay attention to the following matters can reduce the occurrence of: 1, the best home to get well when sick, do not go to school with the disease to kindergarten, which is not conducive to their own recovery, but also easy to infect other children. When the disease first heals, go to less crowded public places or do not go. 2, large fish and meat do not eat or eat less, warm fruits such as mangoes, large cherries do not eat, dried fruits eat less, some children should control sweets. Drink more water and have daily bowel movements. Wash your face with cold water every morning and evening to exercise your ability to tolerate cold. Wear a mask when you just go out in cold and windy weather to reduce the direct stimulation of cold air. 3. Insufficient treatment course for allergic cough or asthma: Many parents are still apprehensive about the hormonal component of nebulizer treatment and always reduce or stop the medication on their own after the cough has subsided. If your child is diagnosed with allergic cough or wheezing bronchitis or asthma, your doctor will give nebulizer inhalation treatment. This treatment often lasts for a long time, and sometimes it is necessary to continue the nebulizer treatment for a while after the cough symptoms are completely relieved. If the medication is stopped as soon as the cough is relieved, it is easy to cause a recurrent cough that does not heal: i.e., the cough stops nebulizing just a little bit, and the cough worsens soon after listening to the nebulization and nebulizing again. In fact, the cough will be prolonged for a longer period of time and the nebulized inhaled medication will be more. How to avoid it: Do not decide to stop the medication on your own, remember! You should reduce and stop the medication under the guidance of your doctor. Start nebulized inhalation treatment when coughing and wheezing starts, and it is better to follow up once every 3 days and ask the doctor to guide the medication. Children with cough and wheezing should not easily give up Western medical treatment and use only Chinese herbal medicine to regulate them. If you choose Chinese herbal medicine, be sure to go to a regular Chinese medicine hospital. When a child’s cough improves significantly and he or she feels well, the child’s cough suddenly worsens again and coughs very frequently, and parents do not understand the cause and become more worried and nervous. What are the stimulating factors that cause coughing: 1. Hazy weather: Not much to say, it’s all tears. Suggestion: If you have the conditions to choose to change your place of residence: fly to the warm and humid south (envy). But most families can only stay where they are because of various factors such as work and school. Then change the small environment: fresh indoor air or wear a mask with filtering effect when you go out. 2. Cold air: cough relief to the outdoors stimulated by dry and cold air, especially on windy days, often induces a very violent cough. This is especially likely to happen in children with sensitive airways or first-time asthma. In this case, if you take your child outside, wear a mask to avoid the direct and strong stimulation of cold air. 3. Strenuous exercise: The child coughs just a little, holds it at home for several days, goes out for a crazy run for a while, and comes back to cough again at night. Suggestions: When your child has just recovered from the disease, do not let your child immediately carry out more strenuous exercise, do not rush to let your child quickly resume sports courses such as running, skiing, ice skating, etc.. Exercise can be, and needs to be, gradual.4. Pay attention to finding allergens: If the child’s cough continues not to ease even after anti-infection and nebulization treatments, look for allergens in the child’s living environment, especially some newly changed things in the family: new flowers, furniture, toys, food, etc. These possible allergic factors need to be carefully identified by parents.
