People who live near airports are more likely to have heart attacks.
Living near an airport increases the risk of a heart attack
A study led by Imperial College London found that residents living under Heathrow Airport's flight paths have an increased chance of being admitted to hospital with a variety of heart issues.
The researchers theorised that noisy aircraft disrupt sleep and raise blood pressure, factors that are linked to heart problems.
Men aged older than 65 appeared to be particularly susceptible to the issues.
Writing in a paper published in the online journal Environment International, the experts concluded: "These findings provide potential evidence that aircraft noise in the late evening and night time may be associated with increased risk of cardiovascular hospitalisations and deaths in the population living within the Heathrow Airport noise contour.
"This is consistent with a mechanism of action via disturbed sleep and has implications for developing respite measures for the communities situated near busy airports."
