Living near airports is linked to a higher risk of heart attacks and strokes for Brits, a new study has found. The study, conducted by University College London, revealed that residents close to major airports in England, such as Heathrow, Gatwick, Birmingham, and Manchester, could be more susceptible to heart issues due to the noise pollution from aircraft.
The research involved examining heart imaging data from 3,635 individuals living near these airports. Those exposed to higher levels of aircraft noise were found to have stiffer and thicker heart muscles, making it more difficult for the heart to pump blood efficiently. This effect was more pronounced in areas with elevated aircraft noise at night, potentially due to disrupted sleep patterns and increased exposure during homebound hours.
Professor Anna Hansell from the University of Leicester expressed concerns about the potential health implications of these findings, suggesting that such heart abnormalities could increase the risk of serious cardiac events like heart attacks and strokes. While the study observed these associations, further research is needed to definitively establish the impact of aircraft noise on heart health.
Apart from affecting sleep, environmental noise can trigger stress responses in the body, leading to elevated blood pressure, constricted arteries, and other adverse health effects. In addition to heart health concerns, exposure to high levels of aircraft noise has also been linked to issues like obesity and high blood pressure.
The study’s senior author, Dr. Gaby Captur, highlighted the importance of considering measures to reduce individuals’ exposure to aircraft noise and mitigate its potential health impacts. Experts emphasised the significance of maintaining heart health through lifestyle factors such as a balanced diet, regular exercise, avoiding smoking, moderating alcohol intake, and managing conditions like diabetes.
As major airports like Edinburgh and Glasgow continue to serve millions of passengers annually, the study’s findings shed light on the hidden health risks faced by those living in their vicinity. Efforts from government and industry bodies are necessary to address the impact of aircraft noise on the health and well-being of communities surrounding airports.
