People who live with constant road noise may be more prone to developing depression, researchers from Germany say. “Although we can’t say for sure, it has been thought that noise causes stress and annoyance,” said lead researcher Ester Orban, of the Center for Urban Epidemiology at University Hospital Essen. The risk was about 25 percent higher for people living in areas with a lot of traffic, compared to those living in areas with little road noise. While Orban calls for caution to conclude that there’s a causal link, she says, “If this noise persists over a long time and is constant and loud, it may contribute to depression.” The study offers a hint to move to someplace more quiet if you suffer from depression.
