Even if you don't smoke, breathing in someone else's smoke can be deadly too. Secondhand smoke causes about 3,000 deaths from lung cancer and tens of thousands of deaths from
heart disease to nonsmoking adults in the United States each year.
Millions of children are breathing in secondhand smoke in their own
homes. Secondhand smoke can be especially harmful to your children's health because their lungs still are developing. If you smoke around your children or they are exposed to secondhand smoke in other places, they may be in more danger than you realize. Children whose parents smoke only outside are still exposed to the chemicals in secondhand smoke. The best way to eliminate this exposure is to quit.
Read more to learn about the dangers of secondhand smoke and how to create a smoke-free environment for your children.
What is Secondhand Smoke?
Secondhand smoke (also known as environmental tobacco smoke) is the smoke a smoker breathes out and that comes from the tip of burning cigarettes, pipes, and cigars. It contains about 4,000 chemicals. Many of these chemicals are dangerous; more than 50 are known to cause cancer. Anytime children breathe in secondhand smoke they are exposed to these chemicals.
The American Academy Pediatrics (AAP) has conducted research on the effects of thirdhand smoke and found that it is also harmful. Thirdhand smoke is the smoke left behind—the harmful toxins that remain in places where people have smoked previously. Thirdhand smoke can be found in the walls of a bar, upholstery on the seats of a car, or even a child's hair after a caregiver smokes near the child.
Your Developing Baby and Smoke
If you smoke or are exposed to secondhand smoke when you're pregnant, your baby is exposed to harmful chemicals too. This may lead to many serious health problems, including:
Miscarriage
Premature birth (born not fully developed)
Lower birth weight than expected (possibly meaning a less healthy baby)
Sudden infant death syndrome (SIDS)
Learning problems and attention-deficit/hyperactivity disorder (ADHD)
The health risks go up the longer the pregnant woman smokes or is exposed to smoke. Quitting anytime during pregnancy helps—of course, the sooner the better. All pregnant women should stay away from secondhand smoke and ask smokers not to smoke around them.
Secondhand Smoke and Your Children's Health
Infants have a higher risk of SIDS if they are exposed to secondhand smoke. Children have a higher risk of serious health problems, or problems may become worse. Children who breathe secondhand smoke can have more:
Children of smokers cough and wheeze more and have a harder time getting over colds. They miss many more school days too. Secondhand smoke can cause other symptoms including stuffy nose, headache, sore throat, eye irritation, and hoarseness.
Children with asthma are especially sensitive to secondhand smoke. It may cause more asthma attacks and the attacks may be more severe, requiring trips to the hospital.
Long-Term Effects of Secondhand Smoke
Children who grow up with parents who smoke are themselves more likely to smoke. Children and teens who smoke are affected by the same health problems that affect adults. Secondhand smoke may cause problems for children later in life including:
Secondhand Smoke is Everywhere
Children can be exposed to secondhand smoke in many places. Even if there are no smokers in your home, your children can still be exposed to secondhand smoke. Places include:
Creating a Smoke-Free Environment
The following tips may help keep your children from being exposed to secondhand smoke:
Set the example. If you smoke, quit today! If your children see you smoking, they may want to try it, and they may grow up smoking as well. If there are cigarettes at home, children are more likely to experiment with smoking—the first step in becoming addicted.
Remove your children from places where smoking is allowed, even if no one is smoking while you are there. Chemicals from smoke can be found on surfaces in rooms days after the smoking occurred.
Make your home smoke free. Until you can quit, don't smoke inside your home and don't smoke anywhere near your children, even if you are outside. Don't put out any ashtrays. Remember, air flows throughout a house, so smoking in even one room allows smoke to go everywhere.
Make your car smoke free. Until you can quit, don't smoke inside your car. Opening windows isn't enough to clear the air and can actually blow smoke back into the faces of passengers in the back seat.
Choose a babysitter who doesn't smoke. Even if the babysitter smokes outside, your children are exposed. Consider changing babysitters to find a smoke-free environment for your children.
Encourage tobacco-free child care and schools. Help your children's child care or school, including outdoor areas and teachers' lounges, become tobacco free. Get your children involved in the effort to make schools tobacco free!
An Important Choice
If you smoke, one of the most important things you can do for your own health and the health of your children is to
stop smoking. Quitting is the best way to prevent your children from being exposed to secondhand smoke.
It may be hard to quit. Talk with your doctor or your child's pediatrician if you need help. There are over-the-counter and prescription medicines that may help you quit. Call 1-800-QUIT-NOW to be connected to your state quitline- they can refer you to local resources and help you quit.
Parents need to make every effort to keep their children away from smokers and secondhand smoke. Parents who smoke should quit for their health and the health of their children.
