Living Near Busy Roads Slightly Raises Parkinson’s Risk but Air Pollution Poses Greater Health Threat

Professor Eitan Friedman, head of the Genetic Institute for Early Detection at Assuta Ramat Hahayal, addressed concerns about living near busy roads and the risk of Parkinson’s disease. He referenced a large Danish study that tracked over three million people for 17 years, which found a 3 to 4 percent increase in Parkinson’s risk for every 10-decibel increase in noise exposure. However, Friedman cautioned against drawing definitive conclusions, noting the study did not control for other significant risk factors such as genetic predisposition or previous head injuries. He described the link between noise and Parkinson’s as relatively minor.

Friedman emphasized that a far more serious and proven health risk for residents near major traffic routes is air pollution. He pointed out that vehicle emissions, particularly soot particles, present a tangible and significant danger to public health, overshadowing the risks posed by noise pollution. His comments highlight the need to focus on air quality improvements to protect those living close to busy roads.
