Living near green areas reduces an individual’s risk of suffering an ischemic stroke, according to a new study.
The findings from the peer-reviewed research are published in the journal, IMIM.
The study looked as exposure to three atmospheric pollutants linked to vehicle traffic among 3.5million people in Catalonia, Spain.
The selected participants were over 18-year-old and had not suffered a stroke prior to the start of the study.
The research analysed the impact of the levels of particulate matter under 2.5 microns (PM2.5), nitrogen dioxide (NO2) and soot particles at the place of residence of each of the people studied.
The researchers also looked at the number and density of green spaces within a 300-metre radius of each person’s home.
Exposure to higher concentrations of each individual chemical increased the participants’ risk of ischemic stroke.
However, individuals living in areas with an abundance of green space were 16 per cent less likely to suffer from an ischemic stroke.
ISGlobal researcher, Cathryn Tonne, said:
“It should be borne in mind that, unlike other air pollutants, which have various sources, NO2 is mainly caused by road traffic.
“Therefore, if we really want to reduce the multiple risks that this pollutant poses to people’s health, we need to implement bold measures to reduce car use.”
Dr. Jaume Roquer, head of the Neurology Service at Hospital del Mar and coordinator of the Neurovascular Research Group at IMIM-Hospital del Mar, added:
“This study demonstrates the real impact that environmental aspects have on the health of the Catalan population.
“In view of the effects of atmospheric pollution, the lack of green spaces, noise, and so forth, more efforts and populational strategies are needed to reduce its impact. Its harmful effects are permanently and globally damaging.
“We must strive to achieve more sustainable towns and cities where living does not mean an increased risk of disease.”
A study published last year found a correlation between air pollution generated by traffic and stroke admissions in Ireland.
Research lead Dr Colm Byrne noted that more than just tailpipe emissions were to blame for traffic pollution hazardous to human health.
Even electric cars produce harmful particulate matter through break pads and tyre wear, the expert said.
