Primary Outcome Measures

Name	Time	Method
Core body temperature measure via telemetric gastrointestinal temperature pill:<br><br>The core temperature sensor (E-celcius, BodyCap™) will be used to assess gastrointestinal temperature. The sensor will be swallowed ~6 hours prior to arriving at the laboratory, so that the sensor has progressed past the stomach by the time the experimental session begins. [ Difference between pre- to post- 3 h heat exposure];Heart Rate<br><br>Heart rate will be measured continuously during the experimental visits via a Polar heart rate monitor.[ Difference between pre- to post- 3 h heat exposure.];Whole body sweat rate Participants will provide a nude weight (in private) before and immediately after the heat stress exposure on a calibrated digital scale. Whole-body sweat rate will be calculated as the difference in the pre and post weight, divided by the time between recorded weigh-ins.[ Difference between pre- to post- 3 h heat exposure.]
