| Gene Block of the University of Virginia in Charlottesville and his colleagues study how the body's natural timekeeping, or circadian rhythm, changes with age. Circadian desynchronosis or jet lag occurs when our body's 24-hour internal biological clock is out of balance. This hormone, produced by the pineal gland, helps regulate the body's circadian rhythm and immune function, and also suppresses tumor growth. |
