Asthma is a common medical condition that affects more than 300 million people worldwide. It is a chronic inflammatory disease that is characterized by sudden constriction of the muscles in the bronchial walls, reversible obstruction of airflow and recurring symptoms of shortness of breath, tightness of the chest, coughing and wheezing.
The most common trigger of an asthma attack is the inhalation of unclean air, such as the airborne irritants and allergens. With the kind of pollution that we have today, we cannot even guarantee that the air inside our house is one hundred percent allergen and dust-free. Even your own room can pose a threat to you or to any of your family members who are prone to asthma attacks.
Other known causes of asthma are certain respiratory infections during childhood. Infants and young children are more prone to develop respiratory issues compared to older children or adults because their immune system is still not that strong. If an infant or a child develops a respiratory illness due to an unhealthy air or environment, there is a big chance that she or he will develop asthma in later years.
