Environmental noise from traffic and aircraft disrupts the body on the cellular level to raise heart disease risk factors, according to a review of the underlying mechanisms that lead to noise-induced heart disease. Sound pollution causes metabolic abnormalities and autonomic imbalance, which is characterised by dizziness and exercise intolerance, said the study.
