In addition to the cold and dry winter, the heavy haze is also an important trigger for coughing. One or two coughs are not terrible, but what worries parents is a cough that lasts for a month, or a cough that comes back after just two days. The words I hear repeatedly in the clinic are: “Doctor, here we go again. What is the cause of the cough that is so bad and so unrelenting? How can we solve each dilemma? Recurrent respiratory infections Recurrent 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. Other children are recovering from minor illnesses and want to eat good food, and they have to eat good food continuously for a few days, but their stools don’t work and they get a fever and cough. How to avoid it: It is not very realistic to avoid respiratory infections completely, but the following things can be reduced: 1. It is better to get well at home when you are sick, do not go to school and kindergarten with a disease, which is not conducive to your own recovery, but also easy to infect other children. 2, the first recovery from illness, crowded public places less or do not go. 3, large fish and meat do not eat or eat less, warm fruits such as mangoes, cherries do not eat, less dried fruits, some children should control the sweet food. 4, drink more water, daily bowel movements. 5, cold water wash your face every morning and evening to exercise the ability to tolerate the cold. 6.Wear a mask when you go out in cold and windy weather to reduce the direct stimulation of cold air. Allergic cough or asthma Treatment courses are not enough. 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. Do not easily give up Western medical treatment for your child with coughing and asthma and use only Chinese herbal medicine to regulate it. If you choose Chinese herbal medicine, be sure to go to a regular Chinese medicine hospital. It is common to encounter irritating factors clinically. The child’s cough is obviously improving and he/she thinks the disease has been cured, but 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 irritants that cause coughing: Hazy weather: not much to say, it’s all tears. Suggestions: If you have the conditions, 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. Cold air: Cough relief. Going outside and being stimulated by dry, cold air, especially on windy days, often induces a very violent cough. This is especially likely 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. Vigorous exercise: Your child has just about recovered from a cough, held it at home for several days, went out for a crazy run, and came back to cough again at night. Suggestion: When your child has just recovered from the disease, do not let your child immediately engage in more strenuous exercise, and do not rush your child to quickly resume exercise classes such as running, skiing, skating, etc. Exercise can be, and needs to be, gradual. Pay attention to finding allergens: If the child’s cough persists without relief 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 discovered by parents.
