Condition
Delayed Sleep Wake Phase Disorder
Delayed sleep-wake phase disorder is a condition where the body's internal clock runs hours late, so people fall asleep very late and wake late, though their sleep itself is normal. Melatonin and morning bright light have the strongest evidence for shifting the clock earlier, though little research on them has been reviewed so far. Magnesium and L-theanine have only limited evidence, and the condition is most common in teens and young adults.
