sleep phase advancement
Therapeutic shifting of sleep timing to an earlier schedule to treat delayed sleep-wake phase disorder.
Full Definition
Sleep phase advancement is a chronotherapeutic technique used to treat delayed sleep-wake phase disorder by gradually shifting bedtime and wake time to earlier hours. This approach can involve multiple strategies including controlled light exposure, melatonin administration, and gradual schedule shifts. Unlike phase delay therapy, which moves sleep time progressively later, phase advancement requires careful implementation to avoid circadian disruption. The goal is to establish a socially acceptable sleep schedule that aligns with work, school, or social obligations while maintaining adequate sleep duration.
Usage
Usage note: Specific therapeutic approach; distinguish from general 'chronotherapy' which includes various timing treatments.
