Transport noise linked to heart risks even with healthy sleep
Cardiologists at Massachusetts General Hospital studied 108,051 adults in Massachusetts using data from 2010 to 2020.
They estimated exposure to noise from road, air and rail transport near each person’s home.
About one-third of participants were exposed to transport noise above 50 decibels.
That level was linked to an 8% to 10% increase in key heart-risk factors, including high cholesterol, high blood pressure and diabetes.
Higher exposure was also associated with a greater chance of a serious heart event.
The links were similar regardless of sleep habits, suggesting regular sleep did not offset the noise-related risks.
The study is due to be presented at an American Heart Association congress in Chicago.
A study found that chronic exposure to transport noise above 50 decibels was associated with more cardiovascular risk factors and a higher likelihood of serious cardiac events.
The association was similar regardless of whether participants had regular sleep, suggesting healthy sleep did not offset the noise-related risks.
The study examined 108,051 adults in the Massachusetts General Brigham Biobank, using data from 2010 to 2020.
About one-third of participants were exposed to transport noise above 50 decibels.
The study was conducted by cardiologists at Massachusetts General Hospital and is due to be presented at an American Heart Association congress in Chicago.

What people are saying
The main finding is that the association between noise exposure and the onset of cardiovascular events — as well as the number of cardiovascular risk factors developed — was similar regardless of sleep.
It was surprising to find that sleep quality does not seem to play any role.
