The Physiological and Perceptual Effects of Wrist Cooling During Exercise in a Thermal Environment

"This study is the first to investigate the effects of wrist cooling via a wearable wristband on physiological and perceptual variables while exercising in an uncompensable heat stress environment and during a recovery period.

Our results suggest that regardless of if the cooling wristband is worn during exercise, when worn during recovery it can lower rectal temperatures faster than passive rest. No physiological or perceptual benefits were seen when wearing the wristband during exercise. Possible applications for this would be half times of sporting events, breaks between competition, and immediately following exercise in the heat.

Uses in other populations exposed to high environmental heat conditions should be studied. However, consideration on utilizing the wrist band over other methods that provide greater rates of cooling, such as cold-water immersion, should be taken."
