Secondhand smoke is a serious health hazard, causing more than 41,000 deaths per year. It can cause or make worse a wide range of damaging health effects in children and adults. Dr. Edward Hill discusses secondhand smoke in todays 60 Second Housecall.
Secondhand smoke is also called environmental tobacco smoke. Its a mixture of two forms of smoke that come from burning tobacco:
Mainstream smoke: The smoke exhaled by a smoker, and.
Sidestream smoke: Smoke from the lighted end of a cigarette, pipe or cigar. This type of smoke has higher concentrations of carcinogens and is more toxic than mainstream smoke. It also has smaller particles than mainstream smoke which can make their way into the lungs and the bodys cells more easily.
Secondhand smoke can be harmful in many ways. For instance, it affects the heart and blood vessels, increasing the risk of heart attack and stroke in non-smokers. Secondhand smoke has the same harmful chemicals that smokers inhale. Theres no safe level of exposure for secondhand smoke.
Secondhand smoke is known to cause cancer. It has more than 7,000 chemicals, including at least 70 that can cause cancer.
In very young children, secondhand smoke also increases the risk for more serious problems, including sudden infant death syndrome.
