The effects of transportation noise in Switzerland has been studied since 2014 by the Swiss National Science Foundation. They have been researching both the short- and long-term effects of the noise, and found that it increases risk for developing cardiovascular diseases. The means of transportation include aircraft, rail, and road traffic noise so far. When it comes to mortality from cardiovascular disease, it was most connected to road traffic noise. Road noise at home also increases the risk for myocardial infarction, hypertension, diabetes and heart failure. The most typical time for noise to have a negative effect on people is when their sleep is disturbed by it. The noise is said to affect individuals so much when it comes to cardiovascular health due to the release of stress hormones which influences insulin metabolism, and sleep problems which also affect the metabolism.
The Swiss created a research project known as SiRENE (Short and Long Term Effects of Transportation Noise Exposure) which includes many experiments involving research, data, and calculations. The four main focuses include: “representative survey in the Swiss population on noise exposure, self-reported sleep disturbances and coping with noise exposure; experimental study in the sleep laboratory for noise-induced sleep disorders, daytime sleepiness and glucose balance; Switzerland-wide modelling of aircraft, rail and road traffic noise, and; determination of noise-induced health risks using data from the Swiss National Cohort Study and the SAPALDIA Study (Swiss Cohort Study on Air Pollution and Lung Diseases in Adults)” (Science Daily 2017). They are still currently studying and expect new results within the year.
