Living in a noisy neighborhood isn't just bad for your sanity; a new study says it's also bad for your waistline, reports the Daily News

Researchers from Sweden's Karolinska Institutet found that residents living in areas with dense noise pollution from trains, planes or cars had a 25 percent higher risk of being overweight than people living in quiet areas. 

The study assessed 5,000 men and women in Stockholm and found that people living by airports were affected the most, but people living in areas where they were exposed to noises from trains, planes and cars were two times as likely to suffer from weight issues than people who were only exposed to noise from one of the above. 

The authors of the study concluded that noise pollution affects waistlines because people who live in noisy areas do not sleep as well as those in quiet areas due to stress. Poor sleep can lead to low energy, which makes it more difficult to exercise. 

Author Andrei Pyko told the Daily News that traffic noise can increase levels of cortisol, which can lead to an accumulation of fat around the stomach area. He advises concerned urbanites to keep the windows shut at night and sleep near a quiet stretch of the road if possible.
