Abstract

Alcohol use Alcoholism Circadian rhythm sleep disorders Insufficient sleep syndrome Obstructive sleep apnea Parasomnias Sleep initiation and maintenance disorders
Alcohol is a commonly used psychoactive substance in the community, with 56% of individuals 18years or older reporting alcohol use in the past month. Its use has been linked to a wide range of sleep-related disorders and associated daytime consequences that may affect the individual's ability to function satisfactorily. Our understanding of alcohol's effect on sleep has improved dramatically over the last few decades because of advances in translational and clinical research at this interface. Alcohol may help an individual to fall asleep relatively quickly, but its deleterious effects involve disrupting underlying sleep mechanisms, interfering with the normal circadian mechanism, aggravating snoring and breathing-related sleep abnormalities, and triggering movements of the limbs during sleep. In this chapter, we examine the link between alcohol consumption (normal and pathological) and a range of sleep-related disorders.
