Watch Out For These Early Symptoms of Childhood Asthma

Asthma is a chronic condition that causes the lungs to overreact to allergens, viruses, exercise, pollutants, and cold air. Bronchial airways become inflamed and swollen during an attack, while excess mucus is produced in the airways and the muscles surrounding those airways contract. This makes breathing difficult, and it's a condition that has come to affect children even more in the modern age. In fact, rates of asthmas have increased in children under five years by an estimated 160% between 1980 and 1994.
