Asthma is a disease that requires long-term treatment. Children can use the ample time during the winter and summer holidays to come to the hospital for detailed examinations and to lay the foundation for the next step of treatment. For children who have an asthma control program in place, they should also insist on regular review. The nature of asthma in children is chronic inflammation of the airways, which is related to environmental and genetic factors. With the progress of industrialized society, environmental pollution has become increasingly serious and there are more and more chemicals in food and daily necessities that can lead to asthma attacks. Many people know that allergens can trigger asthma, but in fact the cold is also a risk factor for asthma. Winter vacation is in the winter, the weather is cold, easy to cause a cold; summer vacation long-term use of air conditioning, indoor and outdoor temperature difference is also easy to induce a cold. Cold-induced asthma is very common, and patients are usually accompanied by pharyngitis, laryngitis, rhinitis and other symptoms. In winter, children with asthma should pay attention to increase and decrease their clothes and wear a good mask; in summer, do not make the air conditioning temperature too low to reduce the occurrence of colds. Children’s bronchial tubes are finer and more sensitive than adults, so they are more likely to suffer from asthma. Asthma in children is easy to be treated as a common cold because of its atypical onset. If a child suddenly sneezes, has a runny nose, and has a prolonged cough that does not improve after normal cold treatment, it is time to wonder if it is a sign of asthma. At this time, parents should take their children to the hospital for a detailed examination. Asthma is a chronic inflammation of the airways, and inhaled glucocorticoids are the preferred treatment to control the inflammation and reduce the acute attacks of asthma. Foreign clinical studies have successively confirmed the efficacy, safety and compliance of glucocorticoid nebulizer inhalation therapy. The International Consensus on Childhood Asthma mentions that early inhalation of glucocorticosteroids in children with asthma with signs such as colds can effectively prevent asthma attacks. Usually children have a heavy study load, parents are afraid of delaying their homework and often treat their children until the disease stops and they think they are well. Asthma is a chronic inflammatory disease of the airways. The inflammation leads to destruction and thickening of the airway walls, which can affect the lung function of children as they develop into adults and requires persistent long-term treatment. The winter and summer holidays are a good opportunity to treat your child’s asthma. Inhaled glucocorticoids are the drug of choice for long-term asthma control, effectively controlling asthma symptoms, improving quality of life, improving lung function, reducing airway inflammation and airway hyperresponsiveness, reducing asthma attacks, and reducing asthma mortality. Regulated therapy requires the use of the lowest dose of medication for maintenance treatment, which improves the quality of life of the child while also reducing side effects, and long-term use will not affect the growth and development of the child. Some children may plan to use their summer and winter vacations to travel, and it is best to do so within their means and with good planning. When traveling, it is best to be accompanied by someone and to bring a summary of the condition and the usual asthma medication, emergency medication for acute attacks, and appropriate medical equipment such as a nebulizer, which should be carried with you. Among them, nebulized inhaled glucocorticoids are the most effective asthma control medication, which can reduce acute asthma attacks in children. In addition, know your destination well and identify and reduce the risk factors with which your child is exposed. Avoid exposure to cold and polluted air when outdoors and bring a good mask. Allergy-prone pollen environments should be avoided, and for heavily hazy weather or during concentrated fireworks displays, avoid going outside. You should pay attention to diet and health care during the break, and avoid food allergies or irritating foods.
