A recent study published in the International Journal of Environmental Research and Public Health examines sleep disturbance and other problems caused by outside traffic and noise, according to MDPI.
Disturbed sleep due to noise from aircraft, railway and road traffic has been shown in laboratory settings as well as in field studies [10,11]. Traffic noise affects several aspects of sleep quality. The time it takes to fall asleep is prolonged in relation to noise exposure. Increased heart rate, blood pressure and changes in electroencephalogram (EEG) during sleep have been recorded in relation to traffic noise exposure. Traffic noise also affects subjective sleep quality and is associated with the notion of not being totally rested after a whole night’s sleep. Awakenings during the night and premature awakening in the morning have been shown in short-term studies but it is concluded that substantial habituating effects exist . However, habituation has not been observed with regard to arousal measured by increased heart rate or EEG-patterns [11,13].
