The pain sensation during training reduced significantly (Figure 1). The sudden increase
during day 12 was merely due to one subject who reported considerable pain only during this
session.

DISCUSSION
It is concluded that a two week period of daily immersion of a hand for 15 minutes in ice
water reduces the experienced pain, but does not enhance finger blood flow in the cold,
although the minimum finger skin temperature in the trained hand tended to be less decreased
as compared to the untrained hand.
