For many people, listening to loud noises can be a stressful experience. Now a new study suggests noise may increase risk of heart disease.

Researchers in Germany and Denmark reviewed years of data and multiple studies on the effects of noise and found that people exposed to frequent noise such as road traffic have higher rates of heart failure, atrial fibrillation, high blood pressure, high cholesterol, and high blood sugar.

They suspect noises above a certain decibel result in a surge of stress hormones that may be harmful to the arteries throughout the body and in the heart.

The study is in the Journal of the American College of Cardiology.

Several years ago, Zoomer Media Founder Moses Znaimer launched the Anti-Noise Pollution League — a list of restaurants where the ideal level for normal conversation is 55 to 65 decibels.
