Breathing in secondhand smoke (SHS) can trigger or worsen asthma related symptoms, cause ear and respiratory infections, and increase the risk of sudden infant death syndrome (SIDS) in children.
Adults can have their risk for lung cancer and heart disease increased by 20-30% by breathing secondhand smoke. So when you quit smoking, other people enjoy the stop smoking benefits. Those around you can breathe easier knowing the air around them is clean.
Back in 1990, it was estimated that 88% of nonsmokers were exposed to SHS. In 2005, that number is now estimated at 40%. SHS continues to be a problem, especially among young children age 3-11 years old (54%) and in the black, non-Hispanic population (56%). The Centers for Disease Control continue to stress that there is no safe level of secondhand smoke exposure.
