After autumn, many parents find that their children suddenly “catch a cold”, which manifests itself in sneezing, usually three or four times, and some children even sneeze a dozen times in a row, and also have a runny nose, itchy nose, and in some cases, a reduced sense of smell. Some parents then casually give their children some cold medicine or antibiotics, but only after a period of time, they find that the child’s symptoms not only do not get better, but also have a serious trend. In fact, this is because parents do not know about children with allergic rhinitis, mistaking allergic rhinitis for a “cold”. There are two types of allergic rhinitis, one is perennial and the other is seasonal, which generally develops in the spring and autumn of each year. The onset of seasonal rhinitis in the fall is usually very sudden, and its symptoms are mainly runny nose and sneezing. Therefore, if your child has a runny nose and sneezing for a long time in autumn, it is best to go to the hospital for a check-up first. If the condition is delayed, it is likely to cause other diseases, for example, 50% to 70% of long-term rhinitis patients will have combined asthma. So for allergic rhinitis, in addition to early detection, and what preventive measures are available? The incidence of infectious diseases (such as colds, pneumonia, etc.) is decreasing, while the incidence of allergic diseases is increasing, which is related to the public health conditions have greatly improved, so there is a view that children do not have to be too clean, early exposure to “dirty” can reduce allergic reactions, many experts agree with some of them. They believe that washing hands before and after meals is a basic hygiene requirement that should be adhered to, but parents should not overprotect their children, who are in the process of maturing immunity, and should be raised in a rough manner, playing with other children, crawling on the ground and playing in the sand will help immune balance. Some children are prone to illness when they first enter kindergarten. Parents do not have to be nervous to take their children home to recuperate, as long as it is not a contagious disease, a cold and other minor illnesses and pains, let the child continue to attend school, which is also the exercise of immunity. 2, strengthen the immune system The immune system is like a warrior defending the body, ready to fight with the invading bacteria. A good immune system will determine your child’s health, learning ability, and quality of life. In order for children to get a comprehensive nutritional supplement to enhance immunity. Parents should ensure that their children have a balanced diet. 3, away from allergens dust mites, dust mites and mold are our three most common allergens. At home, the first should try to keep dry, not especially wet, because children playing on the ground contact with mold, the incidence of rhinitis is higher. Also, the bedding at home is often cleaned, in addition to not to sweep the bed, try to reduce the shaking, sweeping action, in the process of shaking down the dust mites at home dust mites shake up. In addition, if you are allergic to some fur, you must put away the fur cushions, carpets, mattresses and cushions with fur to reduce the allergens in the home. In addition, parents should keep their allergic children away from the grass and pay attention to keeping children warm and cold in the fall when there is a big temperature difference. For children, allergic rhinitis should be intervened and controlled early, and parents should help their children to be well protected and insist on medication when they have symptoms so that they can breathe freely in autumn.
