# Impact of urban noise pollution on sleep disorders and neurological symptoms

## TL;DR

This study shows that urban noise pollution is linked to worse sleep and neurological symptoms like headaches and irritability.

## Contribution

The study provides empirical evidence of the neurophysiological impact of chronic urban noise on sleep and neurological health.

## Key findings

- Higher noise exposure correlated with poorer sleep quality and increased neurological symptoms.
- Individuals exposed to noise above 65 dB showed a greater symptom burden.
- Environmental noise was linked to headaches, dizziness, and irritability.

## Abstract

Urban noise pollution is an emerging public health concern linked to sleep disturbances and neurological dysfunction. This cross-
sectional study evaluated the association between environmental noise exposure and the prevalence of sleep and neurological symptoms among
125 urban residents aged 20-55. Noise levels, sleep quality and neurological complaints were assessed using sound meters, the Pittsburgh
Sleep Quality Index (PSQI) and clinical interviews. Higher noise exposure correlated with poorer sleep quality and increased reports of
headaches, dizziness and irritability. Individuals exposed to noise levels above 65 dB consistently exhibited greater symptom burden, high
lighting the neurophysiological impact of chronic urban noise.
