Regular exercise relieves asthma symptoms

On the other hand, people who have exercise-induced asthma are probably less likely to exercise regularly, so maybe part of the causation is the other way around.

Just 30 minutes a day: Regular exercise relieves asthma symptoms
Concordia research shows those who undertake physical activity year round breathe easier

Millions of people suffer from asthma. Many report having poor control of their symptoms. Fortunately, new research shows there is a simple antidote: 30 minutes of exercise a day, year-round.

Results were overwhelmingly clear: those who engaged in optimal levels of physical activity on a regular basis were nearly two-and-a-half times more likely to have good control of their symptoms, compared with those who did no exercise.

The workout doesn't have to be strenuous. "We're not talking about running marathons here," says Simon Bacon, the study's lead author and a professor in the Department of Exercise Science at Concordia. "Just 30 minutes a day of walking, riding a bike, doing yoga -- anything active, really -- can result in significant reduction of asthma symptoms."

Traditionally, people with the condition have been discouraged from exercising because of a belief that it triggers shortness of breath and attacks. Bacon explains that simple precautionary measures can be taken to avoid the discomforts that can be caused by physical activity.

"The issue of exercise-induced bronchospasm is real -- but if you use your releaver medication, blue puffer, before you exercise, and then take the time to cool down afterwards, you should be okay," he says. "Even if you have asthma, there's no good reason not to get out there and exercise."

"We need to keep in mind that doing something is better than nothing, and doing more is better than less. Even the smallest amount of activity is beneficial."

It's something to keep in mind during winter months, when fitness levels tend to drop along with the temperature, and cold air provides another trigger for asthma symptoms.

"Our study shows that those who were able to engage in physical activity on a regular basis year-round benefit most," says Bacon. If necessary, he suggests finding an indoor place to move, whether it's the gym, a staircase or a shopping mall.

"It's all about being creative and finding environments where the cold doesn't become an issue."
