Every ice climber, mountaineer and late-season rock climber has at one time wondered if they could train their fingers and toes to better withstand cold temperatures. New research published in the European Journal of Applied Physiology tries to answer that question. A team of researchers from the Netherlands and Brock University in Canada took 16 volunteers and had them dip their right hand and foot in 8 C water for 30 minute intervals over 15 consecutive days. The researchers then compared the “trained” hand/foot to the “untrained” hand/foot. Go here to see what they discovered.
