Secondhand smoke: Avoid dangers in the air
How risky is secondhand smoke?
Secondhand smoke causes or contributes to serious health problems, including:
- Lung disease. Exposure to secondhand smoke can aggravate respiratory conditions — especially for people who have asthma or chronic obstructive pulmonary disease (COPD).
- Heart disease. Secondhand smoke damages blood vessels and interferes with circulation, which increases the risk of heart disease and heart attack. A new Mayo Clinic study suggests that secondhand smoke also increases the risk of sudden cardiac death.
- Cancer. Secondhand smoke is a known risk factor for lung cancer. In addition, secondhand smoke contains benzene — which increases the risk of leukemia.
Secondhand smoke poses additional risks for children, who are especially vulnerable to the effects of secondhand smoke. Problems include:
- Low birth weight. Exposure to secondhand smoke during pregnancy increases the risk of low birth weight.
- Sudden infant death syndrome (SIDS). Secondhand smoke increases the risk of SIDS.
- Asthma. Secondhand smoke increases the risk — and severity — of childhood asthma.
- Infections. Children who live with smokers are more likely to develop bronchitis, pneumonia and middle ear infections (otitis media).
Secondhand smoke also causes chronic coughing, phlegm and wheezing, as well as eye and nose irritation.
How can secondhand smoke be avoided?
With planning, you can reduce or eliminate exposure to secondhand smoke. Remember, it's your right to breathe clean air. Start with these simple steps:
- Don't allow smoking in your home. If family members or guests want to smoke, ask them to step outside. Air conditioners and ventilation systems don't effectively remove secondhand smoke from the air.
- Don't allow smoking in your vehicle. If a passenger must smoke on the road, stop at a rest stop for a smoke break outside the car.
- Insist that smoking restrictions be enforced at work. Many states have laws against smoking in the workplace.
- Choose smoke-free care facilities. This applies to child care facilities as well as facilities for older adults. Only choose those with a no-smoking policy.
- Patronize businesses with no-smoking policies. Choose smoke-free restaurants. When you travel, request nonsmoking hotel rooms. Reinforce these no-smoking policies by telling the management that you appreciate the healthy air.
If you have a partner or other loved one who smokes, offer support and encouragement to stop smoking. The entire family will reap the benefits.Previous page
