Important information for all who care about their health: despite the high air pollution of megacities, running and cycling is not just possible, but it is also necessary.

The benefits of physical exercise in the air exceed the potential risks associated with pollution.

Such conclusions were published on the pages of Preventive Medicine by scientists from Cambridge University.

It is widely believed that physical exercises in contaminated areas in themselves pose a threat to our health, and if so, it is not worthwhile to engage in physical education.

The results of the new study suggest that the movement is of great benefit, not comparable with the possible consequences of inhaling particulate matter. The staff of the Center for the Study of Diet and Physical Activity (CEDAR) recall that the movement is the prevention of diabetes, obesity, osteochondrosis, coronary heart disease, stroke, and even several types of cancer.

To compare the benefits of occupations in the air with the potential risk of inhaling particulate matter and toxins, the authors conducted a meta-analysis of several large studies from around the world.

They concluded that only 1% of the world's most polluted cities have a level of harmful substances that 30 minutes a day will do more harm than good.

"According to our model, London and Delhi can be considered the most dangerous cities, where the level of pollution is 10 times higher than in the British capital.

In Delhi, for example, a person needs to ride a bicycle for more than 5 hours a week, so that the benefits of occupations exceed the risk from the air, "notes study author Dr. Marco Tainio from the Cambridge epidemiology department.

According to project manager James Woodcock, two important conclusions need to be drawn from their work: metropolitan residents should not avoid aerial activities, and lawmakers and town planners, in turn, need to take more care of the ecology and urban infrastructure of medbe. en.
