Noise and Stroke

A new Danish study found that prolonged exposure to loud traffic noise is strongly associated to stroke risk among people 65 and older.

Dr. Mette Sorenson of Institute of Cancer Epidemiology of Danish Cancer Society explained that "Exposure to traffic noise is believed to provoke a stress response and disturb sleep, which might increase the risk for stroke."

Some researchers questioned the validity of the study because there were too many other factors that could have affected the outcome--like diet, socioeconomic status, etc.

Still the Danish researchers insisted that noise-deafening building materials could have a positive effect.
