Palm Cooling Explained
Neuroscientist Andrew Huberman explains why palm cooling works and why the hands play a unique role in regulating body temperature.
In this episode, he breaks down how glabrous skin in the palms is designed to rapidly exchange heat with the core and why cooling here can have a bigger impact than ice packs, fans, or cold towels.
If you’re curious how this works beneath the surface, this is a clear, science-first explanation.
What Is Palm Cooling?
And how does it work?
Palm cooling uses specialized blood vessels in your palms to quickly regulate core temperature — a method pioneered by Stanford scientists. Whether you’re training, recovering, or managing heat-related symptoms, Cryo-1 makes this science accessible at home.
Cryo-1 is designed to
Boost Physical Performance
Stanford studies show palm cooling can increase endurance by ~15% and strength training work volume by up to 144%.
Provide Hot Flash Relief
Clinical trials show that effectively lowering core body temperature can reduce the intensity and duration of menopausal hot flashes.
Reduce Outdoor Heat Stress
Golfers, firefighters, soldiers, and outdoor workers can use palm cooling recover faster, lower heart rates, and return to work more safely.
Calm Anxiety
Cooling the Vagus Nerve can lower heart rate, activating the parasympathetic nervous system, and reduce panic symptoms.

Ice vs Palm Cooling: Why They Work Differently
Ice is excellent for treating injuries, but it isn’t designed to cool the body or reduce core temperature. Palm cooling works through specialized blood vessels in the palms that act as natural heat...
Preliminary Study: Cryo-1 and Menopausal Relief
Early reports suggest Cryo-1 may provide rapid relief from hot flashes and other menopausal temperature symptoms. While more research is needed, our initial findings are extremely encouraging.
