Effects of industrial wind turbine noise on sleep and health
Abstract
Industrial wind turbines (IWTs) are a new source of noise in
previously quiet rural environments. Environmental noise is a public
health concern, of which sleep disruption is a major factor. To
compare sleep and general health outcomes between participants living
close to IWTs and those living further away from them, participants
living between 375 and 1400 m (n = 38) and 3.3 and 6.6 km (n = 41)
from IWTs were enrolled in a stratified cross-sectional study
involving two rural sites. Validated questionnaires were used to
collect information on sleep quality (Pittsburgh Sleep Quality Index -
PSQI), daytime sleepiness (Epworth Sleepiness Score - ESS), and
general health (SF36v2), together with psychiatric disorders,
attitude, and demographics. Descriptive and multivariate analyses were
performed to investigate the effect of the main exposure variable of
interest (distance to the nearest IWT) on various health outcome
measures. Participants living within 1.4 km of an IWT had worse sleep,
were sleepier during the day, and had worse SF36 Mental Component
Scores compared to those living further than 1.4 km away. Significant
dose-response relationships between PSQI, ESS, SF36 Mental Component
Score, and log-distance to the nearest IWT were identified after
controlling for gender, age, and household clustering. The adverse
event reports of sleep disturbance and ill health by those living
close to IWTs are supported.
