Living Near Busy Roads May Increase Blood Pressure

Nobody likes traffic. You go to work, and you drive home--anything in between is a nightmare.

But, just imagine if you live next to a crowded freeway, with the constant honking horns, and shouting drivers all day and night. That's bad too.

Apparently, people exposed to traffic noise over 60 decibels have increased risk of high blood pressure.

60 decibels is about the loudness of an electric shaver, or normal conversation. And, according to a new study, published in the journal Environmental Health, that's all it takes to raise the likelihood of hypertension in young and middle-aged people living near traffic jams.

This link was not observed in older people, but among young folks the connection got stronger as the noise got louder. Researchers think it's more obvious in young people because they're less likely to have hypertension.

I can relate. I live near a train track. It's like the scene in My Cousin Vinnie. But, that doesn't boil my blood, the football game does! What about you?

I don't think I buy it. I've lived near the freeway, and I currently live near an airport. It doesn't take long before you subconsciously tune the sounds out completely.

Noise can be stressful, but I agree with Rob that you can tune out after a while. I would think the air pollution from the noisy traffic would raise blood pressure.

I did a review on a study that showed people breathing air pollution for 2 hours had an increase in blood pressure than could potentially trigger a heart attack or stroke. It was published in the AHA journal Hypertension.

I do believe that the constant noise can increase your blood pressure. Sure, after a while you tune out to it, but subconsciously it is still there.

I only have a problem with the noise of airplanes flying over, but a lot of that is because my hometown was the site of a major crash when I was a kid.

I agree with this. Noise can definitely be stressful. I once lived in downtown Tel-Aviv, Israel. On one of the busiest corners. I never slept properly even with earplugs because that city never sleeps. I always felt on edge because I could not relax properly. I lived above a bar, and a pizzeria. It was a high traffic intersection, pedestrian and car. The constant honking and 4 am drunks stumbling home made it impossible to sleep. I moved to a more quiet neighborhood when I could not take it anymore.

What about train tracks? My house is right across the street from a railroad line that gets about 4-5 trains going by per day. We've learned to sort of tune out the noise, but if we leave our bedroom window open, it can get fairly loud.
