Recent studies suggest that there may be a link between breathing in polluted air and an increased risk of stroke. A comprehensive review published in the journal Neurology found evidence of a correlation between levels of pollution and a higher chance of experiencing a stroke within the following five days. Whats concerning is that the risk of fatality also appears to rise as air pollution becomes more severe.
We already know from research that there is a connection between long term exposure to smog and cardiovascular issues, including strokes and heart attacks. Inhaling fine particulate matter (PM2.5) which're tiny particles with a diameter less than or equal to 2.5 microns can cause inflammation promote blood clotting and potentially enter the bloodstream from the lungs leading to chronic diseases and sudden incidents like strokes. However until now it wasn't entirely clear how short term exposure to smog relates to these events.
To shed light on this matter Dr. Ahmad Toubasi from the University of Jordan conducted a review analyzing 110 studies encompassing 18 million cases of stroke. He closely examined levels such as nitrogen dioxide (NO2) ozone, carbon monoxide, sulfur dioxide and atmospheric particulate matter, in various sizes.
The research findings showed that when the concentration of these pollutants is higher there is a noticeable rise in the risk of having a stroke within the next five days.
Further investigation revealed a connection, between levels of air pollution and an amplified likelihood of experiencing a fatal stroke. It was observed that this risk differed depending on the type of pollutants highlighting the importance of reducing air pollution levels to prevent sudden health emergencies and improve overall public health management.
