Delhi frets poor AQI days - Study says air pollution could increase stroke risk by 30 per cent

New Delhi: New Delhi and the national capital region start to fret about the high pollution days come the festive season and winter eventually. Apart from festive cheer, there is smog in the air which often makes it hard to breathe normally – the air quality index (AQI) goes from bad to worse to poisonous. And shockingly, a new study associates excess exposure to air pollution with a heightened risk of stroke. A stroke is a medical emergency caused by a blocked artery that can obstruct smooth blood circulation and oxygen circulation to the brain.

A stroke, if left unattended immediately, can have life-long consequences – from confusion to disorientation to paralysis and whatnot. The findings published in the Neurology journal suggest that fine particles can be harmful to heart health.

How does air pollution affect stroke risk?

Researchers say that after tracking the possible effects of air pollution, they discovered that it can increase the risk of a first and subsequent stroke. The study was focused on PM 2.5 pollution which involves tiny air particles harmful to health. Particle pollution consists of solid or liquid tiny pieces that can spread through dirt, soot, or dust.

Findings from previous research published in the AHA journals associated air pollution with the thickening of the blood and changes in plasma viscosity. In the long term, air pollution can also increase the risk of stroke by hardening the brain arteries and raising blood pressure as well.

These factors collectively can result in the formation of a blood clot which can stop blood from flowing to an organ.

How to dodge the negative effects of pollution?

Researchers say that when air quality reaches dangerous levels, one must reduce outdoor trips unless necessary. As per the Centers For Disease Control And Prevention (CDC), living close to industrial areas can make situations worse – the smoke released from factories and power plants. The particles released can irritate the nose, eyes, throat and lungs causing shortness of breath and cough.
