When analyzing data from 8,600 people, whose average age was 56, the researchers found that in some cases, outdoor sports are not as effective. For example, this effect was observed in areas with the highest levels of air pollution. The research results were published in the Neurology edition.
At the same time, there was a negative effect of polluted air on the work of the brain. True, Melissa Furlong, Ph.D. from the University of Arizona at Tucson and author of the study, emphasized that overall this effect was moderate and it turned out to be weaker than the effect of physical activity: correlated with half the effect of aging of the brain in a year, at the same time sports made the brain three years younger.
