A new study published in the journal Cardiovascular Research shows that a single night of road traffic noise, at levels that are typical of those living in a city, causes stress to the heart and blood vessels.
The findings could help explain why people exposed to long-term traffic noise have higher rates of high blood pressure and heart disease.
The randomized, double-blind crossover study of 74 healthy adults found that low-level nighttime road traffic noise impaired blood vessel function and raised heart rate, as well as disrupted sleep. The study also found blood protein changes linked to inflammation and stress in participants exposed to nighttime noise.
