Living near a busy airport may be more harmful than many realize. Beyond the obvious inconveniences of noise and disrupted sleep, new research has revealed a troubling link between prolonged exposure to aircraft noise and cardiovascular health. According to a study conducted by University College London (UCL) and published in the Journal of the American College of Cardiology, people living near airports may experience significant changes in heart structure and function. These changes, researchers warn, could raise the risk of developing conditions such as heart failure, arrhythmias, and other major cardiac events.
Relation between aircraft noise and heart disease
The UCL study followed 3,635 participants living near some of England’s busiest airports, including Heathrow, Gatwick, Manchester, and Birmingham. Using advanced heart imaging scans, the researchers observed that long-term exposure to aircraft noise was associated with thicker heart walls and less flexible heart muscles. This means the heart has to work harder to pump blood, reducing its efficiency over time. In medical terms, such changes are known as “remodeling,” which can be an early warning sign of heart disease. For residents, this indicates that simply living in a noisy environment could silently strain their heart without obvious symptoms at first.
Night time noise and disrupted sleep
Nighttime noise was found to be especially damaging. Planes flying overhead often interrupt deep sleep, which is essential for the body’s recovery and repair processes. Even when people don’t fully wake up, their bodies register the noise as stress, leading to spikes in blood pressure and heart rate. Chronic sleep disturbance has long been linked to obesity, diabetes, and high blood pressure—all risk factors for heart disease. Residents near airports often report fatigue, difficulty concentrating, and irritability, which may seem minor but collectively point to disrupted sleep cycles that can compound cardiovascular strain.The study also sheds light on how noise pollution directly affects the body. When exposed to constant aircraft noise, the brain activates the “fight or flight” stress response, releasing hormones like cortisol and adrenaline. These chemicals raise blood pressure and trigger inflammation in blood vessels. Over months or years, this persistent stress reaction can stiffen arteries, accelerate plaque buildup, and heighten the risk of heart attacks or strokes. Unlike other pollutants that can sometimes be avoided, noise is harder to escape, making it a continuous and unavoidable stressor for those living close to airports.
Elevated cardiovascular risk
One of the most concerning findings is the heightened risk of serious heart conditions. The study revealed that individuals consistently exposed to high levels of aircraft noise were more likely to develop arrhythmias (irregular heartbeats), heart failure, and even sudden cardiac events. Those with pre-existing conditions such as hypertension or diabetes were especially vulnerable, with some showing up to four times the risk compared to people living in quieter areas. This reinforces the idea that noise pollution is not just a nuisance—it’s a genuine public health hazard on par with air pollution and smoking.
Mitigating the impact
Researchers argue that public health authorities must act quickly to address the risks posed by aircraft noise. Suggested measures include stricter regulations on nighttime flights, investments in quieter aircraft technology, and the redesign of flight paths to minimize noise exposure for residential neighborhoods. In addition, urban planners can play a role by creating buffer zones between airports and housing areas. Soundproofing homes with double-glazed windows and better insulation can also make a meaningful difference for residents until larger policy solutions are implemented.
What residents can do
While systemic changes may take years, individuals can take practical steps to protect themselves. Doctors recommend maintaining a heart-healthy lifestyle with regular exercise, a balanced diet, and stress management practices such as meditation, yoga, or breathing exercises. Installing blackout curtains and using white noise machines may help improve sleep quality in noisy environments. People with existing cardiovascular risks should also be vigilant about monitoring their health through regular check-ups, blood pressure tracking, and timely medical consultations. By combining personal strategies with broader community action, the risks of living near an airport can be reduced, even if they cannot be fully eliminated.
