Reducing Your Risk of Asthma

Preventing asthma is different from preventing acute attacks. Not all risk factors for asthma can be prevented. However, environmental factors can be changed.

Not all risk factors for asthma can be prevented. However, environmental factors can be changed:

  • Breastfeeding may reduce the risk of asthma developing at a young age.
  • Reduce or eliminate smoke exposure.
    • Do not smoke during pregnancy.
    • Avoid places where second-hand smoke is present during pregnancy.
    • Avoid exposing children to second-hand smoke.
  • Avoid common allergy producing substances during pregnancy and during the first 2 years of your child's life.
  • Reduce or eliminate occupational exposures known to cause asthma.

If your are pregnanct, talk to your doctor about taking acetaminophen. It may increase the risk of asthma.
