The concentration of air pollutants tends to rise from morning to early evening, then falls at night. So if you exercise outdoors, try to schedule your workouts for the A.M. Choose routes far away from traffic and automobile exhaust. If that isn't possible, consider joining a health club, so you can exercise indoors.YogaBend to break away from symptoms. The combination of deep, rhythmic breathing and slow, gentle stretching makes yoga an ideal activity for people with asthma. Indeed, many studies have proven yoga to be an effective asthma therapy.In one such study involving 106 adults with asthma, half of the participants received standard treatment, while the rest received 2 weeks of yoga training. Afterward, they were encouraged to continue practicing on their own. Four years later, the people who had engaged in regular yoga sessions reported improved lung function, fewer asthma attacks, and milder symptoms than the people who hadn't learned yoga. They had also reduced their reliance on asthma medications.VisualizationEnvision your airways opening. "Visualization is a powerful asthma therapy," affirms psychologist David Bresler, Ph.D., L.Ac., associate clinical professor of anesthesiology and licensed acupuncturist at the University of California, Los Angeles, School of Medicine. "It can help many people, especially children, reduce or eliminate their need for asthma drugs."If you want to use visualization as part of your asthma-management program, Gerald N. Epstein, M.D., director of the Academy of Integrative Medicine and Mental Imagery in New York City, suggests practicing the following exercise: Close your eyes. Take three slow, deep breaths.

As you exhale, sense your breath traveling down through your body and exiting through the soles of your feet. See your breath as gray smoke that becomes buried deep in the earth. Open your eyes.Chinese MedicineGet to the points. "In Chinese medicine, asthma represents the stagnation of qi, or life energy, in the lungs," says Efrem Korngold, O.M.D., L.Ac. "Treatment involves dispersing qi to eliminate stagnation." One way to do this is with acupuncture. In fact, acupuncture works so well as an asthma therapy that even the United Nations World Health Organization recommends it.During a treatment session, an acupuncturist inserts needles at several specific locations around the body.
