Recent research compared data collected in a cardiovascular study of those who lived in areas with higher airplane noise compared to those who lived in areas with lower noise, and found that Those exposed to higher than recommended levels of aircraft noise may be at greater risk of heart problems and more likely to suffer heart attacks, life-threatening arrhythmias, and strokes.
This is because data from people living near airports showed that Their heart muscles were stiffer, contracted and expanded less easily, and were less efficient at pumping blood through the body. This result was greater for people exposed to airplane noise at night, which could be due to factors such as sleep disturbance and the fact that people are more likely to be at home, and therefore, exposed to noise.
The observational study was published in the Journal of the American College of Cardiology and led by researchers at University College London (UCL). It analyzed data from the UK Biobank of 3,635 participants who had undergone detailed magnetic resonance imaging (MRI) of the heart and lived near Heathrow, Gatwick, Birmingham or Manchester airports.

The effects of noise on health
Following this, the study explained the relationship between airplane noise and differences in the structure and functioning of the heart:
- The noise from our environment, in addition to affect sleep qualitycan trigger stress responses and cause overactivation of the sympathetic nervous system, raising blood pressure, constriction or dilation of the arteries and slower digestion.
- You can also cause the release of cortisol, the stress hormone, which can increase appetite and cause weight gain.
- Furthermore, exposure to high levels of aircraft noise is known to be related to the increased blood pressure and obesity.
“Our study is observational, so we cannot say with certainty that high levels of airplane noise cause these differences in cardiac structure and function, but “Our results add to a growing body of evidence that airplane noise can negatively affect heart health and our overall health,” explains Gaby Captur, lead author of the study and consultant cardiologist at the Royal Free Hospital in London.
