Children face a greater risk than adults of the negative effects of secondhand smoke. When the air is tainted with cigarette smoke, young, developing lungs receive a higher concentration of inhaled toxins than do older lungs because a child's breathing rate is faster than that of adults. Adults breathe in and out approximately 14 to 18 times a minute, and newborns can breathe as many as 60 times a minute. Up until a child is about 5 years old, the respiratory rate is quite fast.
Young children have little control over their surroundings. Babies can't move to another room because the air is smoky. They depend on the adults in their lives to make sure their environment is safe.
Scientists have uncovered numerous risks associated with secondhand smoke for young children and the research continues. To date, there are plenty of sobering facts about how this toxic air damages the health of our kids.
Facts About How Secondhand Smoke Affects Children's Health
- Babies whose mothers smoke during pregnancy often weigh less at birth than those born to non-smoking mothers. Low birth weight is a leading cause of infant death.
- Babies whose mothers smoke during pregnancy are at increased risk for developmental issues, such as learning disabilities and cerebral palsy.
- Babies who are exposed to secondhand smoke after birth have twice the risk for SIDS (sudden infant death syndrome) as babies who aren't exposed. Babies whose mothers smoked before and after birth carry three to four times the risk for SIDS.
- The EPA estimates that between 200,000 and 1,000,000 kids with asthma have their condition worsened by secondhand smoke. Passive smoking may also be responsible for thousands of new cases of asthma every year.
- Among children under 18 months of age in the United States, secondhand smoke is associated with 150,000 to 300,000 cases of lower respiratory tract infections, like bronchitis or pneumonia each year.
- Children in smoking households experience more middle ear infections. Inhaled cigarette smoke irritates the eustachian tube, and the subsequent swelling leads to infections, which are the most common cause of hearing loss in children.
- The lungs of children who regularly breathe in secondhand smoke develop more slowly.
- Research has uncovered evidence that suggests secondhand smoke may be related to childhood leukemia, lymphoma and brain tumors. However, to date, that evidence is insufficient to link these childhood cancers with secondhand smoke definitively.
- On average, children have more exposure to secondhand smoke than non-smoking adults.
- Cotinine levels in children between 3 and 11 years old are more than double that of non-smoking adults.
- An alarming 90% of the exposure kids get to secondhand smoke comes from their parents.
- Over half of American children breathe in secondhand smoke in cars, homes and public places where smoking is allowed.
With upwards of 70 carcinogenic and 250 poisonous known chemical components, it is clear that air laden with secondhand smoke is toxic and unsafe for anyone, especially our kids. It is up to us to provide them with healthy air to breathe.
If you smoke, please make sure that you do all that you can to protect others from the secondhand smoke you create. Better yet, use the resources below to help you get started with smoking cessation.
