risk of developing high blood pressure, heart flutter and stroke is increased
by long term exposure to aircraft noise.
‘The knowledge that exposure to excess noise can lead to ill-health, can come in handy in improving the quality of public health in areas where exposure to transportation-related noise is high.’
risk is particularly greater when the exposure happens during the night.
to noise has been linked to increased sleep disturbances and irritability.
Also, there is a growing concern among the general public about the cardiovascular
impacts of transportation (air, road) related noise.
is the lateral pressure
exerted by the blood on the walls of the arteries.
High blood pressure
occurs when the long-term force of the blood against the
walls of the arteries is high enough to cause health problems, such as heart
blood pressure increases the risk of heart condition.
can cause the hardening and thickening of arteries, known as atherosclerosis
lead to heart attack and stroke.
the study, data was obtained from 420 people living near Athens International
Airport in Greece, where approximately 600 flights take off and land every day. This group
of participants were one among the six groups of people living near six large
European airports who had taken part in the HYENA study in 2013.
study assessed the potential health impacts of aircraft noise in 2004-2006.
noise occurring between 0700 and 2300 hours was categorized as daytime aircraft
noise and that occurring between 2300 and 0700 hours was defined as night-time
the study, the aircraft and road traffic noise exposure levels estimated for
the postcodes of the participants, ranging from less than 50 to more than 60 decibels,
to the findings, the exposure rates observed, were as follows:
of Noise Exposure
- About half of
the participants, under 49%, were exposed to more than 55 dB of daytime
- Around 1 in 4, just over 27%, was exposed
to more than 45 dB of night-time aircraft noise
- Around 1
in 10, at 11%, was
exposed to significant road traffic noise of more than 55 dB
findings showed that 71 people were diagnosed with new cases of high blood
were diagnosed with heart flutter (cardiac arrhythmia
). 18 people had a heart attack between 2004-2006 and
to aircraft noise, particularly at night, was associated with:
- All cases of
high blood pressure
- New cases of high blood pressure
- Doubling in risk of heart flutter diagnosed by a doctor
every additional 10 dB of night-time aircraft noise, there was a 69% increased
risk of high blood pressure.
the exposure also increased the risk of stroke, the findings
showed a weaker and less consistent association between road traffic noise and
studies are needed to draw definitive conclusions on the cause-effect connection between aircraft noise exposure and high
blood pressure risk.
of the study include the relatively small number
of participants, and
the potential effects of air pollution that were not accounted for.
there is growing evidence that exposure to noise is linked to ill health,
according to experts.
