Summary

Heat-related injuries and other physiological stresses continue to be a significant threat to the health and operational effectiveness of the US Armed Forces (Armed Forces Health Surveillance 2011). This is because military personnel are exposed to exertional and environmental heat-stress factors during both deployment and training at US installations in hot and humid climates. Cold water immersion (CWI) is considered the gold standard for the treatment of exertional heat stroke (EHS) and has been shown to increase survival rates to 100% with the implementation of CWI best practices. However, in a field setting other cooling strategies have been developed to aid in the prevention of EHS and other heat-related illnesses. One such proposed strategy is a portable hand cooling device that does not require the use of ice or water. Therefore, the primary purpose of this investigation is to validate hand and back cooling devices using physiological, cognitive, performance, and perceptual responses that occur during and following rest, exercise, and cooling in the heat.

Conditions

• Hyperthermia

Interventions

Type	Name	Description
OTHER	Hand Cooling at 12-15 degrees celsius	hand cooling at 12-15 degrees celsius will be performed for active cooling by having participants place their hands on the cooling device set to this temperature
OTHER	Hand Cooling at 16-20 degrees celsius	hand cooling at 16-20 degrees celsius will be performed for active cooling by having participants place their hands on the cooling device set to this temperature
OTHER	hand and back cooling at 12-15 or 16-20 degrees celsius	hand and back cooling at 12-15 or 16-20 degrees celsius will be performed for active cooling by having participants place their hands on the cooling device set to this temperature while also wearing the back wrap cooling device set to this temperature
OTHER	Passive cooling	participants will sit in a chair and "passively cool" (no active intervention)
