About this trial
Our study has two goals. The first goal is to find a blood test that can detect signs of strain from heat in the body ("a biomarker"). Second, the study team wants to identify types of devices that can help people cool down quickly.
By identifying biomarkers for heat strain, scientists can better track and treat the health effects of heat. The study team will identify such biomarkers by simulating, in a laboratory-based environment, the heat and physical work that real-world workers experience.
In addition, the study team plans to test two cooling technologies that might keep people cool during physical activity.

Treatments tested in this trial
Hand cooling table
Other interventionA participant can rest their hand on the cooling table after the one hour exercise session, and this should cool their body quickly. Cold water is pumped throughout the cooling table.
Cooling bandana
Other interventionA participant will tie a bandana that has been soaked in cold water onto their forehead. They will wear this bandana during the one hour exercise session.
