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:
“The city sleeps and the country sleeps,
The living sleep for their time, the dead sleep for their time,
The old husband sleeps by his wife and the young husband sleeps by his wife;
And these tend inward to me, and I tend outward to them,
And such as it is to be of these more or less I am,
And of these one and all I weave the song of myself.”
—Walt Whitman (1819–1892)
