The Study

A study conducted at Imperial College London found an increase in cardiovascular disease among residents of areas adjacent to Heathrow Airport.

The study analyzed hospitalizations due to cardiovascular disease among residents whose homes are on the flight path of Heathrow Airport. Researchers found evidence of a “slightly increased risk” for people who had heard louder sounds the previous night. Men over 65 are especially affected.

The Link Between Airport Noise and Cardiovascular Disease

Researchers said airplane noise interferes with sleep and increases blood pressure and stress hormone levels, both of which are factors associated with heart problems. They added: “These results provide potential evidence that late-night and late-night aircraft noise may be associated with an increased risk of hospitalization for cardiovascular disease and death.”

Evidence for an association between aircraft noise and CVD mortality was limited, although this could be explained by the small sample size.

Concerns and Actions Taken

Aircraft noise was a contentious issue during Heathrow’s attempt to get approval to build a third runway. Modern passenger aircraft are quieter than previous models, but there are growing concerns that more flights will lead to more disruptions.

Heathrow, who Imperial College London backed the study, says reducing airborne noise exposure is part of its sustainability strategy. Airport managers say they have reduced noise levels by 28% since 2006.

Conclusion

The study was based on figures recorded between 2014 and 2018 and was published in the International Environment Journal. The findings provide evidence of a link between airport noise and cardiovascular disease, particularly among those living near Heathrow Airport.

As concerns grow, actions are being taken to reduce noise levels and mitigate the health risks associated with airport noise.
