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:
“To die, to sleep—
No more, and by a sleep to say we end
The heartache and the thousand natural shocks
That flesh is heir to—’tis a consummation
Devoutly to be wished. To die, to sleep.
To sleep, perchance to dream. Ay, there’s the rub,
For in that sleep of death what dreams may come
When we have shuffled off this mortal coil
Must give us pause.”
—William Shakespeare (1564–1616)
