New Study Reveals: Nighttime Airplane Noise Poses Heart Health Risks

Concerning findings from UCL in London suggest that loud airplane noise, especially at night, may harm heart function and increase the risk of conditions such as heart attacks, arrhythmias, and strokes. The study analyzed cardiac imaging data from more than 3,600 residents living near major airports in England, including Heathrow and Gatwick.

“Environmental noise, such as aircraft noise, can trigger stress responses in the body, leading to increased blood pressure and impaired heart function,” explained Dr. Christian Topirceanu. According to his explanation, prolonged exposure to nighttime airplane noise causes the release of the stress hormone cortisol, which may contribute to weight gain and overall damage to the cardiovascular system.

The researchers emphasized that airplane noise differs from other types of noise because of its unpredictability, making it harder for the brain to adapt. Another study found that heart function in people exposed to nighttime noise decreased by 10% to 20% compared with those who moved to quieter areas.

Professor Anna Hansell from the University of Leicester concluded, “The quality of our sleep is a major factor affecting health. It is important to continue researching ways to reduce the harm caused by nighttime environmental noise.”

The study underscores the need to review night flight policies in densely populated areas and to adhere to the World Health Organization’s guidelines for maximum noise levels.
