Asthma is a common lung disease that cause the airways to narrow during symptoms. The muscles tighten and mucus builds up constricting the airway and making it difficult to breathe. Some symptoms of asthma are trouble breathing, coughing, wheezing, and chest tightness. Allergies, irritants, smoke, air pollution, dust and physical activities are all triggers for asthma.1 Childhood asthma is the most serious chronic disease in children and infants.2
I think childhood asthma is rising mainly due to the environment. As we all know air pollution and tobacco smoke has greatly increased over the years.3 Air pollution and tobacco smoke are both triggers of asthma.2 This could mean children are being exposed to these trigger early on
