Recent researches on traffic noise and heart attack
Researchers from Denmark, the USA, Switzerland, and Germany collaborated to investigate the impact of traffic noise on heart health, going beyond the audible aspects. In a study published in the American Heart Association’s journal, Circulation Research, scientists analyzed multiple studies. They found that for every 10 decibels (dBA) of traffic noise, the risk of heart problems increases by 3.2%. The scientists found out that loud noises can affect our genes, body clocks, and metabolism. It can lead to heart problems. They also discovered that exposure to airplane noise at night can cause stress-induced cardiomyopathy.Stress can make our blood pressure go up and hurt our blood vessels.
