Experts from the Imperial College London drew their findings from an experiment that involved monitoring 140 volunteers in their sleep. The subjects, whose homes were located near one of three airports, were observed in terms of blood pressure levels, which were monitored every 15 minutes.
Constant observations of the subjects' blood pressure in relation to the ambient noises of their sleep environments, revealed that noises louder than 35 decibels, which according to the AFP was about equal to either a plane zooming over a person's head, or heavy traffic, caused a noticeable rise in blood pressure.
The same results were seen when scientists observed the effects of a snoring partner on a person's blood pressure, high levels of which were, according to the AFP, defined by the World Health Organization as 140/90, or higher.
The researchers, led by Lars Jarup, concluded that noise pollution has an effect that goes beyond normal irritation and discomfort.
"We know that noise from air traffic can be a source of irritation, but our research shows that it can also be damaging for people's health," the Independent quoted Jarup. "This is particularly significant in the light of plans to expand international airports."
Jarup continued to say that a 10-decibel increase in the noise pollution during a person's sleep increased the risk of high blood pressure by 14 percent. The increase level proved evident in men and women, based on a similar study.
"It is clear that measures need to be taken to reduce noise levels from aircraft, in particular during night-time, in order to protect the health of people living near airports," said Jarup.
High blood pressure is known to be a factor for more serious conditions such as stroke, dementia, heart disease and kidney disease.
