Other research indicates that people spend approximately 90 percent of their time indoors. In the last several years, a growing body of scientific evidence has indicated that the air within homes and other buildings can be more seriously polluted than the outdoor air in even the largest and most industrialized cities. Indoor air pollution is one risk that you can do something about. And some are risks we might decide to avoid if we had the opportunity to make informed choices. Some we choose to accept because to do otherwise would restrict our ability to lead our lives the way we want. Driving in cars, flying in planes, engaging in recreational activities and being exposed to environmental pollutants all pose varying degrees of risk. Following the advice given will not necessarily provide complete protection in all situations or against all health hazards that may be caused by indoor air pollution.Īll of us face a variety of risks to our health as we go about our day-to-day lives.
