Circadian Rhythm Sleep Disorders (50 minutes)
Studies suggest that 1 in 600 adults suffers from Delayed Sleep Phase Disorder1. That's half a million American adults! In addition, it's been estimated that as many as 10% of teens are affected2, another two million American teens. Most of the teens will grow out of it.
It is estimated that half of all totally blind people suffer from Non-24-Hour Sleep-Wake Disorder3: another 90,000 Americans. Non-24 also occurs in sighted individuals4, but the prevalence is unknown, and the disorder is almost certainly underdiagnosed.
