Impact of urban noise pollution on sleep disorders and neurological symptoms

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.
