Prolonged and heavy use of alcohol is associated with persistent sleep disturbances. Objective and subjective measures of sleep quantity and quality were collected on 164 individuals undergoing detoxification. A high prevalence of sleep disturbance was found in this sample. Sleep quality improved by week 4 but continued to be altered, signaling a target area for recovery management. This study supports the high prevalence of sleep disturbance in individuals undergoing alcohol treatment. Health promotion strategies in an addiction recovery model should address quality-of-life enhancements for individuals and their families including optimizing sleep quality and duration through sustained recovery.
