Abstract

|
The effect of wearing protective gloves on the thermal ex-changes in cold water was studied in 4 Korean women wet suit divers. The subject was immersed in the water of critic-al temperature (average temperature was 16.5C) and rested for 3 hours.
The steady-state rectal temperature was lower with gloves(37.01 f 0. 10(SE)C) than without gloves (37.310. 1C), the different being statistically significant (P (0.05). On the other hand, the metabolic heat production was 17% higher with gloves (52.63 f 4.90(SE)kcal/hr m2) than with-out gloves(44.932.49). Consequently, the total peripheral insulation was reduced (19%) by wearing gloves. At a given average skin temperature the threshold rectal temperature for shivering was approximately 0.5C higher without gloves than with gloves.
These results suggest that 1)the total insulation of the wet suited subject is effectively increased by selective cooling of the hand, and 2) the metabolic response to body cooling is sensitively affected by the skin temperature of the distal extremities. The practical implications of these findings, are discussed.
