Advanced sleep phase syndrome
People whose body rhythms follow a cycle of less than 24 hours go to bed earlier and earlier and eventually can't stay awake past early evening. This condition, called advanced sleep phase syndrome, is more common among older people. Treatments being studied include bright light therapy in the evening, which helps reset the body's clock, and carefully timed doses of melatonin.
