A new study led by researchers at University College London suggests that living near airports with high aircraft noise may increase the risk of heart problems, such as heart attacks and strokes. The study analyzed heart imaging data from 3,635 people living near four major airports in England. The results were compared with data from individuals in quieter areas.
Impact of Nighttime Noise Exposure
The study found that the risk of heart issues was particularly higher for people exposed to greater levels of aircraft noise at night. Researchers believe this may be due to factors like disrupted sleep and more time spent at home, which increases exposure to noise. Nighttime noise seems to have a stronger effect on heart health than daytime noise.

Heart Abnormalities Linked to Aircraft Noise
The study also identified that heart abnormalities in people not exposed to aircraft noise could raise the risk of major cardiac events. Those with abnormalities had a risk of heart attacks, arrhythmias, or strokes that was two to four times higher than those without heart issues.
Cardiologist Gaby Captur, one of the researchers, noted that the study was observational. This means they cannot definitively say that high aircraft noise directly caused these changes in heart structure and function. However, she added that the findings contribute to a growing body of evidence linking aircraft noise to adverse health effects.
The study highlights the importance of considering environmental factors, such as noise pollution, in public health policies aimed at reducing heart disease and improving overall health. Further research is needed to fully understand the long-term effects of living near airports and to confirm these findings.
