Have you ever felt shortness of breath, heavy coughing, chest tightening, or wheezing while exercising? If so, you may be someone that is experiencing exercise-induced asthma. It may be that exercise exclusively triggers these symptoms, however other asthmatics may experience symptoms due to environmental factors such as cold air, allergens, respiratory infections, some basic medications (e.g. Advil, Aspirin) or strong odours.
If you have felt any of these symptoms while exercising, you need to consult a medical professional ASAP. Treatment can be relatively easy, and can help relieve symptoms. Ultimately, exercise-induced asthma should not prevent you from exercising, and will always ensure health and fitness related gains.
