A new study shows a correlation between noise pollution and death. According to the study's author Jaana Halonen of the London School of Hygiene & Tropical Medicine, "road traffic noise has previously been associated with sleep problems and increased blood pressure, but our study is the first in the U.K. to show a link with deaths and strokes." The study was conducted in London using information from 8.6 million people from 2003 to 2010.

"From this type of study, we can't tell for certain what the risks of noise are to an individual, but these are likely to be small in comparison with known risk factors for circulatory diseases like diet, smoking, lack of exercise and medical conditions such as raised blood pressure and diabetes," said study co-author Dr. Anna Hansell.

The relationship between noise and death is an association, not a cause-and-effect relationship.
