Abstract:

The effect of added insulation of the dorsum back or palm of the hand, or both, on the rate of finger cooling was studied. Additional insulation on the dorsum was found to reduce the rate of finger cooling at -20 F but not at 0 F hand-cooling temperatures. Added palm insulation had no effect on finger cooling under either of these two cold-exposure conditions. Combined dorsum and palm insulation produced a reduction in the rate of finger cooling at -20 F this was largely attributable to the dorsum insulation alone. Within the range of insulation values used, systematic increases in the amount of dorsum insulation were not found to cause significantly greater reductions in the rate of finger cooling. Supplementary findings of the study were that added dorsum insulation reduced the rate of cooling of the dorsum area but did not offset the heat loss from the palm. Conversely, additional palm insulation lessened the rate of cooling of the palm but did not alter the rate of dorsum cooling. Reductions in finger-cooling rate due to the presence of added dorsum insulation did not necessarily follow from reductions in the rate of dorsum cooling.
