According to Swedish researchers. Exposure to noise from traffic, trains, planes and maybe even deafening restaurants could be linked to a burgeoning belly.

The study in Occupational & Environmental Medicine followed 5000 people around Stockholm for four years. It found that women had a 0.08-inch increase in waist size for every additional 5 decibels in noise exposure. For men the increase was .06 inches. And the risk of a larger waist rose with the number of sources of noise someone was exposed to at the same time.
