Secondhand smoke contains lots of toxic chemicals including cyanide, formaldehyde, lead, carbon monoxide and benzene. Any of these toxins alone is dangerous, so imagine the danger when they are combined. These chemicals can remain in the air for many hours.
Breathing secondhand smoke, even for a short time, can lead to a reduction of oxygen in your circulatory system and can cause lung irritation. The residue of the smoke is also a concern. This is called thirdhand smoke and will cling to the hair, clothing, cushions and carpeting and is risky, especially for kids.
Serious health problems can arise from long-term exposure to secondhand smoke. Secondhand smoke can increase the risks of developing cardiovascular disease. It also damages the blood vessels and circulatory system. Asthma and other lung diseases can be caused or aggravated by secondhand smoke. The research about secondhand smoke also indicates that it can lead to lung cancer, as well as other types of cancer.
Children who are exposed to secondhand smoke face additional risks. Pregnant women exposed to secondhand smoke risk delivering babies with low birth weights. The risk of Sudden infant death syndrome rises as well. Children exposed to secondhand smoke are at a higher risk of developing infections of the ear and respiratory tract.
You can avoid secondhand smoke by not allowing smoking in your home or car. You should also make sure that any smoking restrictions at your workplace be followed. When you are in public, choose establishments that have no-smoking policies. And finally, try to keep away from smokers. If you have to share a space with them, try to stay far away.
