What makes palm cooling effective?

1. Elevated core body temperature: When the body is in a state of heat stress, the central nervous system downregulates muscular output, resulting in fatigue and reduced performance.
2. Heat dissipation: To counteract heat stress, the body responds by removing heat via vasodilation (including significantly increased blood flow to the palms of the hands) and sweating. The intent is to remove excess heat from the body. 
3. Glabrous skin: Specialized, dense vasculature (AVAs: Arteriovenous Anastomoses) found in the palms of the hands functions as the optimal heat transfer interface on the human body.
