Living near an airport can increase the risk of suffering STROKE
A study argues that living near an airport can increase the chances of dying victim of stroke, heart disease and circulatory diseases. This is because those who are exposed to high levels of noise caused by aircraft is up to one fifth more likely to need hospital treatment or of dying from these diseases.Researchers claim that the noise can trigger a response to stress hormones, which increases the blood pressure disturbs sleep. Has already been requested further investigations, especially in case of night flights.The study, conducted by Imperial College London and King's College London, involving 3.6 million people living near Heathrow Airport, in England. The data were compared the noise produced by aircraft during the day and night with the rates of hospitalization and mortality.The analysis showed that the risk of living is 10% to 20% higher in areas with high levels of noise caused by aircraft-which cover about 70 thousand people â€" compared to quieter areas.The researchers analyzed 2001 noise levels and hospital data between 2001 and 2005. Took into account other factors related to heart disease, such as social exclusion, ethnic composition, the road traffic noise, air pollution and lung cancer rates.The study encompassed 12 London boroughs and nine districts outside the city, where the noise of aircraft exceeds 50 decibels."Our study raises important questions about the potential role of noise on cardiovascular health," stressed one of the authors of the study, Paul Elliott. However, the exact role that the noise has on health has not yet been set. Other factors are already known to increase the risk of heart disease â€" such as poor diet, smoking, lack of exercise, high blood pressure and diabetes.Photo: under Creative Commons license
