Green Areas and Strokes (03-22-22)

Living near a green area has been linked to less likelihood of having a stroke.  Researchers report that “The risk of suffering an ischaemic stroke, the most common type of cerebrovascular event, is 16% less in people who have green spaces less than 300 metres from their homes. . . . The study took into account information on exposure to three atmospheric pollutants linked to vehicle traffic. . . . The results indicate a direct relationship between increased levels of NO2 in the atmosphere and the risk of ischaemic stroke. For every increase of 10 micrograms (µg) per cubic metre, this risk increases by 4%. The same happens when PM2.5 levels increase by 5 µg/m3. In the case of soot particles, the risk increases by 5% for every 1 µg/m3 increase in the atmosphere. These figures are the same for the entire population, irrespective of other socio-economic factors, age or smoking habits.” Chemical concentrations were also measured at residences.
