Study Summary

More than 5 million patients are admitted to the intensive care unit every year in the United States; most of these patients experience profound sleep and circadian disruption. Promotion of circadian alignment (i.e., alignment of the body's clocks) would make it possible to strategically schedule behaviors such as sleep and eating at normal body clock times, which is predicted to improve sleep quality and metabolic function. This project will test the ability of a sleep chronobundle (i.e., sleep promotion and circadian treatment bundle) to normalize circadian alignment and subsequently test if this realignment also improves sleep and metabolism.
