Asthma Triggers: Gain Control
About secondhand smoke and asthma
Secondhand smoke can trigger asthma episodes and increase the severity of attacks. Secondhand smoke is also a risk factor for new cases of asthma in preschool-aged children. Children's developing bodies make them more susceptible to the effects of secondhand smoke and, due to their small size, they breathe more rapidly than adults, thereby taking in more secondhand smoke. Children receiving high doses of secondhand smoke, such as those with smoking parents, run the greatest relative risk of experiencing damaging health effects.
Actions you can take
- Don't let anyone smoke near your child.
- If you smoke — until you can quit, don't smoke in your home or car.
