I've completed two different palm cooling tests and the results have been pretty substantial.
Palm cooling has been shown to boost performance by delaying the onset of fatigue. There are special networks of blood vessels under the palms of your hands, bottoms of your feet and on portions of your face. These special portions of your skin are called "glabrous skin" and the network of vessels underneath are call arteriovenous anastomosis (AVAs).
My two tests have produced improvement of 15% and 28% with two different formats using AVA Cooling Tech's (www.avacooling.com) demo hand cooling tool. Biohackers, athletes, coaches and anyone looking to delay the onset of fatigue and get an incredible performance boost should look into the effects of palm cooling. From sand volleyball, to weight lifting, to running intervals, to crossfit workouts, the strategy and tool can easily be applied.
