Participants will attend 6 to 8 in-person visits to the study clinic, including three overnight stays. People will complete surveys and medical tests. The study will last about 4 to 6 months.

Being studied: Central Clock Misalignment; Peripheral Misalignment

Conditions: Sleep; Metabolism Changes; Circadian Rhythm; Lifestyle Factors; Sleep Hygiene; Sleep Hygiene, Inadequate; Sleep Deprivation; Insufficient Sleep; Circadian Misalignment; Circadian Dysregulation; Light Exposure
