Constant noise pollution over the years increases the risk of stroke significantly. Elderly people and urban residents are particularly affected.

Especially in cities, people are exposed to constant noise pollution. The constant traffic noise has a scientifically proven negative effect on the human organism. Researchers have now proven that even minimal sound levels mean not only a risk of heart attack and high blood pressure. Almost every twelfth stroke is now caused by constant noise.

Noise in the big cities damages health People in big cities are exposed to constant noise pollution. The residents are bothered by noise and sound from all sides. Residents of high traffic streets in particular are experiencing rising sound levels every day. In the past, some studies had already indicated that constant noise can have a health-endangering effect. It was previously known that the louder the risk of heart attack increases significantly, the louder it is. Researchers from the Danish Cancer Society have now found out from a study that the risk of suffering a stroke also increases when people are exposed to constant noise.

Study data from over 50,000 people evaluated For the study, the scientists examined the data from over 50,000 test subjects. They found that just 10 decibels of traffic noise are enough to increase the risk of a stroke by 14 percent. Upon closer examination, the researchers found that the risk was not significantly increased among study participants under the age of 65. Rather, people over the age of 65 were affected. For every 10 decibels of noise, the risk of stroke increased by 27 percent. The louder the noise level, the higher the risk of suffering a stroke. The noise levels were not very pronounced. 60 decibels correspond to the volume of a stereo system with the room volume muted.

Other risk factors were excluded In order to exclude further risk factors, the researchers considered additional pollution such as pollution, noise from trains and airplanes, and unhealthy lifestyles such as smoking, alcohol and being overweight. For the evaluation, the Danish scientists used a special calculation system that was able to distinguish and differentiate between the individual regions, their noise levels and the state of health and age of the participant. The researchers had also observed the sound level of individual regions for several years. They differentiated between traffic volume, driving speed, road conditions and the height and distance of residential areas and houses. The research team set 42 decibels as the minimum sound level. The maximum value was 82 decibels. Around 35 percent of the subjects were exposed to a higher load of over 60 decibels. Around two-thirds of the stressed participants did not change their place of residence during their studies.

19 percent of all strokes are accounted for by constant noise pollution. However, the data cannot be used as a general value, since noise pollution changes constantly depending on time and location. In addition, the scientists primarily examined noise levels in large Scandinavian cities. Nevertheless, the scientists sum up in the science magazine "European Heart Journal", the data clearly show that people over the age of 65 under constant noise exposure have higher stroke risk values. "Eight percent of all strokes and 19 percent of all strokes of people over 65 are attributed to this of traffic noise. ”the study director Mette Sorensen finally explained in the journal. However, it is still unclear why permanent noise leads to an increase in cardiovascular diseases. Further medical studies would have to follow. (sb)
