10 Everyday Triggers of Asthma and Tips to Live Better

Cigarette smoke. Both active and passive smoking are among the strongest triggers of asthma. The chemicals in tobacco smoke irritate the lungs and increase inflammation, making breathing much harder. Even being near someone who smokes can provoke an attack.

Tip: Avoid smoking completely and stay away from places where others smoke. Patients with asthma should also avoid exposure to exhaust fumes from cars and polluted environments.
