Key Takeaways
AIDr. Khaled Al-Nemer, professor and consultant of cardiology and arterial catheterization at the College of Medicine, has revealed a link between chronic road noise and an increased risk of coronary artery disease. He noted that a 10-decibel rise in noise levels is associated with about an 8% increase in risk.
Writing on his X (formerly Twitter) account, Al-Nemer explained that continuous noise keeps the nervous system in a constant state of alertness, leading to persistent secretion of cortisol and adrenaline hormones. He said this gradually damages the lining of blood vessels.

He added that the timing of the largest heart attacks differs, with the most severe cases typically happening between 1:00 and 3:00 a.m., while noting that other factors may also influence these findings.
