Dr (Col). Manjinder Sandhu, Principal Director, Cardiology, Max Healthcare discusses how pollution affects the heart and what can we do to protect it.
Did you know, of the 20 most polluted cities in the world, a significant 10 cities belong to our country. And it is certainly not a record to be proud of. Furthermore, if you are under the impression that air pollution is only affecting our lungs, there is more to it than what meets the eye. Recent research shows that small particles of air pollution can significantly affect the function of the heart apart from your lungs. That means it’s a double attack on your health. Studies have also indicated that when there is a significant concentration of pollution, the number of deaths and hospitalizations increases in countries across the world.
So, what’s the heart of the problem?
According to health experts, it is the microscopic particles known as nanoparticles which are smaller than 2.5 microns that are of concern. Our lungs and nose, are designed to filter out larger particles but not smaller ones. These small particles enter the bloodstream and block the arteries surrounding the heart and lungs. In the long run, this can lead to heart disease or a heart attack. Elders, in particular, must exercise caution because even brief exposure to pollution can result in stroke, arrhythmia, or heart failure.
If you have heart disease or an underlying heart condition, particulate matter floating in the air can increase your risk of having a heart attack. On days with poor air quality, everyone, but especially those with heart disease, should change their behaviors to avoid or limit their time outside.
So, what’s the way out?
- Stay insideWhen it’s smoggy outside, it’s best to stay indoors and use an air purifier to get cleaner, fresher air. And, certainly, smoking indoors is a no-no because it affects not just you but also your loved ones.
- Avoid congested areasIf you have to travel through a congested area, try to avoid it and take another route, which may take longer but will be cleaner.
- Get to know your neighborhoodPay attention to places and times of day where air quality affects you the most.
- Walk away from the cars on the pavementIt’s nice to be a good Samaritan by strolling on the sidewalks, but it’s much better if you can walk away from all the automobiles on the road. After all, you don’t want to inhale all that smog.
- Pay attention to the air in your homeMake sure that the air in your home is free of smoke, dust and chemical fumes. To enhance the air quality in your home, try using a moist rag instead of a feather duster when dusting, checking and replacing your furnace filter on a regular basis, and making your home a smoke-free zone.
- Listen to your bodyLearn to listen and understand your own reactions amid bad weather–and when you need to adjust your plans.
- Take care of the environmentYou can take care of your heart by caring for the environment by adopting simple measures like planting more trees at your place, walking instead of using your car all the time and using public transportation if need be. The change starts with you.
