Traffic noise linked to higher cholesterol and lipid levels in blood

A new study from the University of Oulu has found that nighttime noise exposure is associated with changes in blood cholesterol and lipid-related metabolites in adults, which are known risk factors for cardiometabolic diseases. The LongITools study, published in Environmental Research, is one of the largest studies so far to investigate how long-term exposure to traffic noise may influence biological processes in the body.
