Traffic Noise Reduces Life Expectancy & Increases Risk Of Stroke, Research Finds
New research from the London School of Hygiene & Tropical
Medicine, King’s College London, and Imperial College London, has found
that prolonged, repeated exposure to traffic noise appears to be
correlated with a decreased life expectancy and an increased risk of
stroke.
This new research follows on the heels of much recent research that
shows a correlation between the air pollution caused be vehicle
emissions and a large number of serious diseases and ailments.
The findings are the result of the analysis of data concerning 8.6
million residents of various portions of London, gathered between the
years of 2003 and 2010. The researchers involved in this work utilized
the data to discern patterns relating to variations in road traffic
noise in the various postal codes. The data was divided and organized
with regard to variations based on the time of day.
Data relating to deaths and hospital admissions in a given area were
then compared, with the data for those between the age of 25–74 kept
separate from the data for those over the age of 75.
Apparently, in places where the average traffic noise was higher than
60 decibels, people were found to be 4% more likely to die than in
areas where the average was under 55 dB. The vast majority of this
disparity was found to be relating to deaths via heart disease or
circulatory disease. So, in other words, deaths that can be assumed to
be related (at least in part) to sleep, stress, and blood pressure
problems.
Additionally, adults that lived in places where traffic noise was
over 60 dB were apparently 5% more prone to experience a stroke — as
compared against those living in quieter areas. Traffic noise during the
night hours, in particular, seems to have an outsized effect —
increasing stroke risk by 5% (for the elderly).
These findings aren’t likely to surprise anyone who’s lived in both
noisy city areas and also in quieter places — the effect on health is
pretty obvious to anyone that pays any attention to their wellbeing.
That said, perhaps having this reality supported by scientific studies
will lead to changes of some sort….
One way to improve the situation, perhaps not fully but to a notable degree, would be to switch to electric vehicles. Another bigger effect would come from a societal switch to bicycling for transportation needs.
