Study Summary
This research study will evaluate changes in resting metabolic rate, appetite, and heart rate variability following overnight exposure (8 h/night) to normobaric hypoxia (NH) or normobaric normoxic (NN). In randomized order, participants will sleep one night in NH conditions (\~15% oxygen; achieved with nitrogen dilution, equivalent to \~8500 feet elevation) and another night in NN (control) conditions (\~20% oxygen; achieved with nitrogen dilution, equivalent to \~1000 feet elevation).
Primary Outcome
Resting metabolic rate will be accessed using indirect calorimetry (TrueOne 2400, Parvo Medics, Salt Lake City, UT) following 8 hours of overnight exposure to NH or NN.
Interventions
