Non-clinical Sleep and Wake-up Uses
A dawn simulator can be used as an alarm clock. Light enters through the eyelids triggering the body to begin its wake-up cycle, including the release of cortisol, so that by the time the light is at full brightness, sleepers wake up on their own, without the need for an alarm.

Famous quotes containing the word sleep:
“I shall die as my fathers died, and sleep as they sleep; even so.
For the glass of the years is brittle wherein we gaze for a span;
A little soul for a little bears up this corpse which is man.
So long I endure, no longer; and laugh not again, neither weep.
For there is no God found stronger than death; and death is a sleep.”
—A.C. (Algernon Charles)
