A newstudy conducted by a team of specialists at the University of Southern California’s Davis School of Gerontology says that exposure to air pollution can accelerate the cognitive decline in adults and seniors.
The research was presented as a part of the study concerning the human ageing process. The study is based on observation of more than 15,000 adults who were above 50 years of age, mapping their test scores through pollution concentration maps. The study showed that adults and seniors living in highly polluted areas aged up to 3 years faster than those living in areas with the least air pollution.
Thus the study also makes a veritable case for use of home air purifiers, especially in homes with children and seniors.
Fine air pollutants can in fact mix in our bloodstream through respiration and reach the brain via the body’s blood circulation mechanism. Prolonged inhalation of these pollutants, especially by children or seniors, who have underdeveloped or ageing immune systems, can cause stress on the body and the mind,which in turn accelerates the ageing process.
However, we can control indoor air pollution by using smart home products such as air purifiers and humidifiers, travelling in closed transportation and using masks when outside.
