A large-scale scientific study revealed that long-term exposure to traffic noise is linked to an increased risk of Parkinson's disease, highlighting the negative impact of noise pollution on brain health. The study relied on tracking millions of individuals over many years, with results proving that continuous noise leads to sleep disturbances and increased levels of stress and inflammation, which are factors directly contributing to nerve cell damage. Researchers recommended the importance of considering environmental standards in urban planning to provide quiet residential environments that mitigate these risks.
