Asthma is a chronic inflammatory disease of the airways that carry air in and out of the lungs. Asthma causes the lining of the airways or branches of the lungs (bronchial tubes) to become inflamed and sensitive, which then causes the airways to narrow. These changes make breathing difficult and cause a feeling of not getting enough air into the lungs. Common symptoms include cough, shortness of breath, wheezing, chest tightness and excess mucus production.

Asthma symptoms often vary over time, due to different environmental triggers such as mould or pollen spores. Just like the leaves on a tree change, these triggers can be different throughout the four seasons of the year.

At present it is spring, so all the tips are related to the spring season. Tips for summer, fall and winter are already on this site as well.
