Noise increases health risks: noise promotes cardiovascular diseases and diabetes
Especially in cities, people are exposed to constant noise pollution. According to scientific studies, the constant noise has a negative impact on the human organism. According to a new study, traffic noise increases the risk of cardiovascular diseases and diabetes.
Noise is bad for your health
Nowadays we are exposed to noise pollution almost everywhere. There is a lot of noise in cities, not least because of the often immense traffic. This is not only annoying, it is also harmful to health. Studies have shown that the constant noise makes many urban residents depressed and blood pressure rises. It also causes headaches, nervousness, restlessness and stress. In addition, traffic noise increases the risk of cardiovascular diseases and diabetes, as researchers from Switzerland are now reporting.
Short and long-term effects of traffic noise pollution
An interdisciplinary Swiss study consortium has been investigating the short and long-term effects of traffic noise pollution for the population in Switzerland as part of the SiRENE study by the Swiss National Science Foundation (SNSF) since 2014.
The research project SiRENE (Short and Long Term Effects of Transportation Noise Exposure) is carried out under the direction of Swiss TPH (Swiss Tropical and Public Health Institute).
The first results of the study have now been presented at the ICBEN congress (International Commission on Biological Effects of Noise) in Zurich.
Noise at night disturbs sleep
The results of the study published so far show that aircraft, rail and road traffic noise can have undesirable health effects.
According to the scientists, the connection to cardiovascular diseases is most evident in street noise. The risk of dying from a heart attack increases accordingly by four percent per ten decibels increase in street noise pollution at the place of residence.
Traffic noise also increases the risk of high blood pressure and heart failure.
"Noise events at night that regularly disturb sleep are particularly critical," study director Martin Röösli, professor of environmental epidemiology at the Swiss TPH and the University of Basel, said in a message.
"Even lower noise levels than previously assumed have negative effects on health."
Noise also favors diabetes
In addition to cardiovascular diseases, traffic noise also increases the risk of developing diabetes. This is shown by a study of 2,631 people who are exposed to different levels of noise.
"Two mechanisms play a role here," explained Nicole Probst-Hensch, head of the Department of Epidemiology and Public Health at Swiss TPH.
“On the one hand, the chronic release of stress hormones influences insulin metabolism. On the other hand, it is known that sleep problems negatively affect metabolism in the long term. ”
Although the health effects of traffic noise are substantial, factors such as exercise and smoking are significantly more important, says Röösli. (ad)
