What is delayed sleep phase syndrome (DSPS)?

Delayed sleep phase syndrome occurs most often in young adults when the time of onset of sleep is shifted later. The misalignment is stable, and normal sleep occurs once the individual falls asleep. However, it may be extremely difficult for these individuals to arise at normal times for school or work demands. This can develop when individuals stay up late on weekend nights before going to bed early on Sunday night, and this results in sleep onset insomnia and difficulty arising the next morning. Circadian rhythm disorders are best controlled by going to sleep and waking around the same time on all nights (i.e., sleep hygiene).
