Transport Noise Linked to Heart Disease Risk
A Massachusetts General Hospital study links exposure to transport noise with higher rates of cholesterol, blood pressure, and diabetes problems.
Updated on Nov. 7, 2026 in Heart Disease
Researchers at Massachusetts General Hospital analyzed data from more than 100,000 adults with an average age of 57 and found that transport noise exposure was associated with higher risk of heart conditions. Exposure above 50 decibels was linked to an 8 to 10 percent increased risk of high cholesterol, high blood pressure, and diabetes.
Why it matters
The findings suggest that environmental noise from roads, rail, and air travel may contribute to cardiovascular disease alongside more commonly studied factors. The association held after accounting for age, sex, and sleep quality.
The analysis combined health records from more than 100,000 adults averaging 57 years old with government transport noise measurements, finding an 8 to 10 percent higher risk of high cholesterol, high blood pressure, and diabetes above 50 decibels. It remains unclear from the available data whether noise exposure directly drives these conditions or reflects other factors.
The players
Massachusetts General Hospital
A major Boston teaching hospital and research institution affiliated with Harvard Medical School, known for extensive cardiovascular and population health research.
The details
Researchers examined whether heart risks linked to transportation noise differed between people with normal and abnormal sleep, and found the relationship was similar in both groups. The strongest association was with high cholesterol, followed by high blood pressure and then diabetes.

Big Picture
With roughly 16 million people in the UK living with high blood pressure, the study extends attention beyond diet and genetics toward the built environment. It suggests urban transport noise may be a modifiable contributor to a burden already documented at national scale.
Residents living near busy roads, rail lines, or airports may face greater exposure to transport noise. Because the study found links to cholesterol, blood pressure, and blood sugar, people with these conditions may want to discuss noise exposure with their clinicians as part of broader cardiovascular risk management.
The takeaway
Environmental noise is an emerging cardiovascular risk factor that individuals can partly mitigate through choices like window insulation and quieter routes. Maintaining regular checks of cholesterol, blood pressure, and blood sugar remains the most direct way to track that risk.
