Advanced Sleep Phase Disorder (ASPD), also known as the advanced sleep-phase type (ASPT) of circadian rhythm sleep disorder, is a condition that is characterized by a recurrent pattern of early evening (e.g. 7-9 PM) sleepiness and very early morning awakening (e.g. 2-4 AM). This sleep phase advancement can interfere with daily social and work ...
Sleep–wake logs and/or actigraphy monitoring for at least two weeks document a consistent habitual pattern of sleep onsets, usually later than 2 am, and lengthy sleeps. Occasional noncircadian days may occur (i.e., sleep is "skipped" for an entire day and night plus some portion of the following day), followed by a sleep period lasting 12 to ...
A circadian rhythm is an entrainable, endogenous, biological activity that has a period of roughly twenty-four hours. This internal time-keeping mechanism is centralized in the suprachiasmatic nucleus (SCN) of humans, and allows for the internal physiological mechanisms underlying sleep and alertness to become synchronized to external environmental cues, like the light-dark cycle.

When a person struggles to fall asleep or stay asleep without any obvious cause, it is referred to as insomnia, [2] which is the most common sleep disorder. [3] Other sleep disorders include sleep apnea, narcolepsy, hypersomnia (excessive sleepiness at inappropriate times), sleeping sickness (disruption of the sleep cycle due to infection ...
The Centers for Disease Control and Prevention recommends adults get seven to nine hours of sleep per night for optimal health. The benefits of getting appropriate sleep include reduced stress ...
Sleep deprivation, also known as sleep insufficiency [2] or sleeplessness, is the condition of not having adequate duration and/or quality of sleep to support decent alertness, performance, and health. It can be either chronic or acute and may vary widely in severity.
The possible causes of non-24-hour sleep-wake disorder are 2-fold: (1), extrinsic: isolation from daily light cycles (such as working in an environment completely devoid of natural lighting); [citation needed] and (2), intrinsic: where some condition, such as blindness or malfunctioning biochemical response to light in the subject, prevent ...
