Citizens living near the park live longer - meta-analysis with more than 8 million people

A team of international scientists has conducted the most extensive research on the connection between urban green spaces and mortality. It figured out that life expectancy could be extended by living near a park. This may be due to the fact that green spaces clean the air, reduce stress and motivate physical activity. The results are published in The Lancet Planetary Health.

Scientists from the Barcelona Institute of Global Health (Spain), the University of Colorado (USA) and the World Health Organization have conducted a systematic review and meta-analysis of data from nine longitudinal studies on the urban green spaces and mortality rates’ connection. These studies were conducted in China, the United States, Canada, Spain, Italy, Switzerland and Australia according to the same standard: the authors observed human health and how far they lived from parks, squares and other green spaces based on satellite images. In total, more than eight million people were affected by the meta-analysis.

As a result, the authors concluded that the more green spaces - trees, bushes, herbs, etc. - are planted, the more green spaces are planted. - near the houses of citizens, the more chances to live a long and healthy life. And if two percent more trees are planted within 500 meters of the house, the risk of premature death for the residents of this house will decrease by four percent.

Scientists suggest that perhaps this advantage is due to the fact that green spaces clean the air of pollution, help relieve stress and are, in principle, beneficial to the mental health of urban residents. In addition, people living near the park tend to be more active, less likely to suffer from obesity, metabolic and cardiovascular problems, the study notes.
