ST. LOUIS, Mo. (KMOX) - Two new studies – one done in Britain, the other in the United State – show exposure to high levels of aircraft noise could be bad for our hearts.
The two studies show people living near airports who were regularly exposed to noise above 63 decibels were 20 percent more likely to be hospitalized for cardiac conditions.
“Potentially the mechanism for this is increasing background stress, increasing adrenaline surges within the body that we’re not aware of,” Dr. Michael Lim, Cardiology Chief at St. Louis University Hospital, said.
Lim explained that to accommodate higher levels of noise, our blood pressure raises a little and our overall stress level inches up as well.
“That manifests itself into a higher level of heart attacks and strokes,” he added.
Lim said we should become more aware of background noise exposure in our daily lives and try to have some relaxing quiet time everyday.
Compared to air pollution, however, excess noise from planes appears to play a much smaller role in increasing heart disease risk.
