Why two hands is 1.6, not 2
Both palms draw on the same central blood supply, so a second cooled hand takes you to about 1.6 times one hand, not two. Why that is, an...

Passive or battery-powered palm cooling: what electricity buys you, and what it does not
Battery-powered palm coolers hold a set temperature for an hour or two. Passive ones carry a fixed amount of cold. Which moves more heat ...

Is Colder Better for Palm Cooling?
Colder is not better through the palms. Two things decide how much heat leaves: the temperature, and how much heat the surface can keep t...

Newton, athletes, and the cooling gradient
The first thirty seconds of rest matter most. Why Newton's Law of Cooling explains when palm cooling works best between training efforts.

Why Palms and Face Exchange Heat More Efficiently
Not all areas of the body regulate heat equally. Peripheral regions like the palms and face contain specialized vascular structures that ...
