Control Your Asthma
Talk to your doctor about what types of exercise, and how often, are right for you.
Know Your Triggers
Your doctor can help you figure out what your triggers are. Then try to avoid them when you work out.
Pick Your Day and Time of Day
If pollen makes your allergic asthma worse, keep close tabs on the pollen count in your area.
Consider exercising outdoors in the early evening, when pollen counts are lower, instead of early morning when pollen counts are higher. Check online for your local pollen count before you head out.
When the pollen count is extra high, pass on your run or soccer game and exercise indoors that day instead.
Puff Before You Exercise
You should always carry a short-acting bronchodilator, such as albuterol, with you. These drugs work quickly to open up your airways. Use your rescue inhaler 10-15 minutes before exercising, even if you don't have symptoms yet.
No matter what sort of exercise you prefer, warm up beforehand and ease into the activity. A few simple stretches and maybe a short walk before you run or pick up your tennis racket can set you up to make it through your exercise without breathing problems.
Love the Humidity
Warm air doesn't constrict your airways the way cold and dry air can. For that reason, swimming is often a good activity for people with allergic asthma. At the pool, you're breathing in warm, humid air that won't shut down your lungs.
