Triggers are things that bring on your symptoms. If you cough only at nighttime, you may be allergic to dust. Being active is an important, fun part of life. If we sit around all the time, our muscles get weaker and our lungs tire out more easily. Talk to your doctor about using your inhaler before exercising.
Swimming is an excellent sport for people with asthma.
Many Olympic athletes have asthma. Work with your doctor to find out how you can be active without flaring up your asthma. Understand what medications you need to help you feel better. Know the proper way and time to take them. This will put you, not your asthma, in control of your activities.
