Usual Care, Standard Light
Patients will be enrolled within 30 hours of noon on enrollment day (e.g. at or after 6am on the prior calendar day). Enrollment will occur before noon, and the day of enrollment is termed study day 1.
Patients will undergo monitoring (light levels, circadian alignment), but otherwise have usual care.

10,000 Lux Bright Light, 4 Hours
Patients will be enrolled within 30 hours of noon on enrollment day (e.g. at or after 6am on the prior calendar day). Enrollment will occur before noon, and the day of enrollment is termed study day 1.
Patients will undergo monitoring (light levels, circadian alignment), starting on study day 1. Patients will be exposed to bright light from 8am to noon starting on study day 2 and continuing through study day 5. Bright light exposure will occur in the Intensive Care Unit (ICU) and on the floor if the patient is transferred.
Feasibility metrics will be collected.
10,000 lux bright light, 4 hours: Bright light will be delivered by a free-standing 10,000 lux device that will be positioned next to the patient's head of bed. At the estimated distance of 36 inches from light source to the patient, we anticipate approximately a 1,250 lux dose at the patient's eye. Light will be delivered from 8am to noon.

10,000 Lux Bright Light, 8 Hours
Patients will be enrolled within 30 hours of noon on enrollment day (e.g. at or after 6am on the prior calendar day). Enrollment will occur before noon, and the day of enrollment is termed study day 1.
Patients will undergo monitoring (light levels, circadian alignment), starting on study day 1.
