Sleep Disruption Induced Impairments in Bone Formation

Participants in this arm will sleep for 8 hours at their habitual time for 1 week outpatient. Food will be provided for the outpatient week by the study. After the outpatient week participants will check into our inpatient Clinical Translational Research Center (CTRC) for a 9 day inpatient stay. During their inpatient stay participants will be sleep restricted to a 5 hour/night sleep opportunity for nights 2-7 of their inpatient stay. Outcome measures include a 24-hour serum draw (urine and blood) which will occur on night 1 (pre) and night 8 (post). Patients will be given a 10 + hour recovery sleep period on night 8 of their inpatient stay.
