Asthma is a condition in which your airways narrow and swell and produce extra mucus. This can make breathing difficult and trigger coughing, wheezing and shortness of breath.
These changes cause the airways to become narrow, so that there is less space for the air to flow into and out of your lungs.

Symptoms include

Coughing
Tight feeling in the chest
Wheezing – whistling noise when breathing
Shortness of breath
Struggling to breathe

These symptoms are often worse at night, in the early morning or during exercise.
Asthma that is triggered by exercise may be helped by medication and/or warm up exercises.
Asthma is a treatable health condition. Although at present there is no cure, with good management, people with asthma can lead normal, active lives.
