Final answer:
Delayed Sleep Phase Syndrome (DSPS) is a circadian rhythm sleep disorder characterized by a consistent delay in the timing of sleep, leading to problems with waking up at a desired time.
Step-by-step explanation:
If you find yourself going to bed later and later each night, and this pattern has become consistent, you may be developing Delayed Sleep Phase Syndrome (DSPS), which is also known as Delayed Sleep Phase Disorder. DSPS is a type of circadian rhythm sleep disorder where the individual's sleep is delayed by two or more hours beyond the conventional bedtime. This delay in falling asleep leads to difficulty in waking up at a desired time. The main treatment methods include maintaining a consistent sleep schedule, light therapy, and in some cases, medication.
Unlike DSPS, Sleep Onset Insomnia refers to general difficulty in falling asleep. Advanced Sleep Phase Syndrome is the opposite condition, where individuals fall asleep earlier than desired. Lastly, Insomnia Disorder is a broader term that includes difficulty in falling asleep as well as staying asleep throughout the night.
