Study Details

Brief summary:

This research will determine the breathing, heart rate and other responses to four surprise events. For two events, virtual reality goggles will be used to create a realistic experience of falling out of a boat and rolling out of a boat or falling of a paddleboard. Two final events will involve falling into a dunk tank with either cool (20℃) or cold (10℃) water.
