Sound pollution could lead to increased waist circumference and obesity, says study
That noise pollution is bad for the ears, everyone knows. But science has shown that the damages of excess sound can bring to health are greater than that. Researchers from the Karolinska Institutet Institute for Environmental Medicine found a link between living in very noisy places and increasing weight and waist circumference. The study looked at 5075 people living in that there is excessive noise pollution, with traffic noise from cars, airplanes and trains. Through a questionnaire and medical examination, they analyzed the World Health Organization (WHO) obesity markers: body mass index (BMI), waist circumference and waist-to-hip ratio.
As a result, the researchers realized that every five decibels more than sound pollution there was an increase of 0.21 inches of the waist measurement of people observed when constantly exposed to at least one of these sources of noise pollution.
