(NAPSI)—Most of us feel alert when it’s light outside and want to sleep when it’s dark. Light is the cue that helps our internal body clock—or “master body clock”—synchronize to the 24-hour day. In people with a circadian rhythm disorder, however, the timing of this clock is disrupted, causing our rhythms to get out of sync.

Non-24-Hour Disorder, or Non-24, is one of the rarest and most difficult-to-correct circadian rhythm disorders.

The disorder, although rare in the general population, is unfortunately very common in people who are totally blind, affecting 50 to 70 percent of people who are totally blind.
