Using the Cold Pressor Test to Assess Effectiveness of Low-Cost, Immersive Virtual Reality Therapy

This study is testing whether or not low-cost, virtual reality (VR) headsets for mobile phones can be used as a potential distractor from pain and thus would have clinical applications as a low-cost, non-pharmaceutical method to increase pain tolerance in patients undergoing painful or uncomfortable procedures. To do this, the investigators are asking volunteers to submerge their hand up to the wrist in cold water (Cold Pressor Test), either while playing an interactive virtual reality game on the headset, or while wearing a VR headset that is turned off as a control. The investigators will record the participants' tolerance to cold water as measured by how long the participants are able to keep their hand in the cold water.
