Primary Outcome Measures

Name	Time	Method
VR Effect on Pain Tolerence	Duration of ice bath (approximately 0 - 4 minutes)	Given that the cold pressor test produces an uncomfortable experience, we considered longer duration within the ice bath to represent increased pain tolerance. Measured in seconds (s).

Secondary Outcome Measures

Name	Time	Method
VR's Effect on Perceived Pain Intensity	Duration of ice bath (approximately 0 - 4 minutes)	During ice bath data collection participants will be asked to report pain on a numeric rating scale from 0-10, 0 being no pain and 10 being most excruciating pain imaginable every 30 seconds during ice bath
Skin Conductance Response Density (SCRD)	Duration of ice bath (approximately 0 - 4 minutes)	The effects of VR on modulating sympathetic response in the presence of painful stimuli, was assessed by analyzing SCRD per 30 second interval. We refer to each of these 30 second intervals as a separate epoch. Skin conductance is expected to increase with increasing sympathetic nervous system activity, as sympathetic activity increases sweat secretion to increase skin conductance.
