Breathing is an important part of the human condition. If you don’t breathe, you can’t live. The air around us, however, is not exactly as pure as it once was . I think that all of us know the bad side effects of breathing in second-hand smoke. You’ve probably been told that, since there’s no filter to reduce the amount of toxins and carcinogens, you’re at greater risk than smokers if you allow yourself to be exposed regularly. Smokers have the filters on their cigars and cigarettes to reduce the damage, but people who stand there and take in the second-hand smoke don’t have that protection.
The potential consequences of prolonged exposure consists of a list of respiratory disorders covering everything from minor fits of coughing to something as severe as lung cancer.
According to scientists the air now is more toxic than at any other because of smoke of cars and factories. Science also has an impressive list of all sorts of airborne pathogens, bacteria, and viruses that are floating in the air and affect our health negatively.
