Asthma is an inflammatory respiration disease. It makes breathing difficult and also can make some physical activities difficult or impossible. It is a noncommunicable disease that affects both children and adults. Due to inflammation and tightening of the muscles around the small airways, the air passages become narrow. This narrowing of the air passage causes cough, wheezing, chest tightness, and shortness of breath. These symptoms are intermittent and may also get worse at night or during exercise. Other external “triggers” can make symptoms worse. Triggers vary from one person to another, these include viral infections like cold, smoke, dust, fumes, grass and tree pollen, weather changes, strong soaps, animal fur and feathers, and perfume.

India contributes 11.1% of the global burden and over 42% of related deaths making it the asthma capital of the world. Under-treated people can suffer sleep disturbance, tiredness during the day, and poor concentration. People suffering from this respiratory illness and their families may miss school and work which shows the financial impact on both family and community.

Some people get symptoms triggered only by exercise. This is known as exercise-induced asthma. It is also known as exercise-induced bronchoconstriction (EIB). This is because of the tightening and narrowing of airways not caused by having this illness. Elite athletes or people doing strenuous exercise in very cold conditions may get affected by EIB. Irrespective of diagnosis and you are getting symptoms like tight chest, coughing, breathlessness, or fatigue during or after exercising contact your doctor. He will run some tests like:
- Spirometry test: Your doctor will test your lung function to make sure you don’t have underlying asthma.
- Exercise challenge tests: It is a treadmill or other equipment. It is a way to see how your airways are reacting to exercise. Conducting spirometry tests before and after exercise tests can show whether you have exercise-induced bronchoconstriction (EIB) or not.
- Treatment: After the tests, your doctor gives you treatments that help with the symptoms so that you can continue to exercise safely. It might be reliever medicine to take immediately before your medicine.
