A 2002 study of older adults (age 40–65) in San Diego found 3.1% had complaints of difficulty falling asleep at night and waking in the morning, but did not apply formal diagnostic criteria. [63] Actimetry readings showed only a small proportion of this sample had delays of sleep timing. [citation needed]
Falling asleep and waking up at the same time every day, as well as getting natural light exposure throughout the day and dimming artificial lights at night, will help strengthen your circadian ...
We get into a pattern of waking and sleeping that sees us opening our eyes in the middle of the night. The room is dark, but sure enough, the clock reads the same time as it did the night before...
The subjects demonstrated a phase advance of sleep-wake rhythms that was distinct not only from control subjects, but also to sleep-wake schedules widely considered to be conventional. The subjects were also evaluated using the Horne-Östberg questionnaire , a structured self-assessment questionnaire used to determine morningness-eveningness in ...
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.

Sleep inertia is a physiological state of impaired cognitive and sensory-motor performance that is present immediately after awakening. It persists during the transition of sleep to wakefulness, where an individual will experience feelings of drowsiness, disorientation and a decline in motor dexterity.
Sleep research conducted in the 1990s showed that such waking up during the night may be a natural sleep pattern, rather than a form of insomnia. [2] If interrupted sleep (called "biphasic sleeping" or " bimodal sleep ") is perceived as normal and not referred to as "insomnia", less distress is caused and a return to sleep usually occurs after ...
