What's wrong with children having dry cough after exercise?

Some children do not show any abnormalities when they are quiet, but after some strenuous exercise, they often have severe dry coughs; such children often do not show any abnormalities when they do not exercise during the day, but will have coughing symptoms after going to bed at night. So, what is going on? What should we pay attention to in our daily lives?

Doctors say that cough variant asthma is one of the common respiratory diseases in children. Because children's bronchial mucosa is delicate and their ability to resist external pathogenic bacteria infection is low, it is easy to become inflamed and cause coughing.

Some children cough more often at night or in the early morning, without wheezing or fever. Sometimes chest X-rays and blood tests show no obvious abnormalities. The cough worsens when exercising or crying. This type of cough may be an allergic cough, clinically known as cough variant asthma. It is a latent asthma with cough as the main clinical manifestation. In the early stages of asthma, 5% to 6% have persistent cough as the main symptom, and the cough is mostly irritating and contains sputum.

Keep the indoor environment clean and the air fresh. Dust mites often gather in large numbers on some toys. Quilts, pillowcases and carpets should be cleaned and exposed to the sun regularly. It is best not to keep pets or plant flowers and plants at home, and avoid contact with paint. Eat less raw, cold, greasy and irritating food. Some high-protein, high-energy foods such as shrimp should be eaten with caution. Drink more water and eat more vegetables and fruits.

If you experience precursor symptoms such as itchy eyes and nose, sneezing, runny nose, tears, and coughing, you should seek treatment early. Strengthen physical exercise to improve immunity, but children with exercise-induced variant asthma should limit the intensity of exercise appropriately.

If a child has a dry cough after exercise, he or she may be suffering from variant asthma. Such children must pay attention to timely treatment. At the same time, the child should be prevented from engaging in strenuous exercise to reduce the occurrence of this symptom. In normal times, you should also pay attention to keeping the indoor air fresh, eat more vegetables and fruits, and eat less irritating food.
