A surprising source of noise has unfortunate health implications

Can noisy neighbors be a health hazard?

This is Sandra Tsing Loh for the Loh Down on Science, saying:

Yes!  If your neighbor is a busy metropolitan airport. 

So says a new study by Anna Hansell and colleagues at Imperial College London.  They studied boroughs in the vicinity of Heathrow Airport, one of the busiest in the world. 

Those three-million-plus residents enjoy the glamour of international travel – all day, every day.  The "whoosh" of 747s.  The "buzz" of A-380s.   And the party doesn’t stop when the sun goes down.  Annoying?  You bet.  Life-threatening?  Unfortunately, yes.

Excessive noise – like road noise – has already been linked to high blood pressure and sleep deprivation.  But when the researchers compared hospital records and decibel ranges in those “fly-by” neighborhoods, they also saw a noticeable increase in strokes, cardiovascular disease, and mortality.  A separate Harvard University project studied U.S. airports, with similarly dire results.

The researchers say city planners should "have a heart" when it comes to building airports in urban areas.
Either that, or supply lots of free air miles to Hawaii, with a whole lot of those cute little neck pillows.  And delicious honey-roasted peanuts.  It’s only fair.
