Whole Body Cooling with Protective Clothing during Cold Water Immersion
Abstract
Heat losses during water immersion have been evaluated for nude and clothed heated copper manikins (Goldman et al., 1966), and for nude men (Goldman and Gee 1973). Data are now presented for subjects immersed in still, cold water (28 C and 20 C), nude (.14 clo) and in 6.25 mm vinyl (.43 clo), 9.4 mm polyurethane (.61 clo), and 6.25 mm neoprne (.76 clo) wet suits. Metabolic rates (M), EKG, heat flow (discs at 5 sites), rectal (Tre) and 10 skin temperatures (Ts) were obtained in air, then during a 60 min immersion period, and for 20 min thereafter. the Tre at 60 min for the nude, and all clothed conditions, taken together with the decreases in M associated with increased insulation, suggest that the effect of insulation is to conserve the metabolic energy cost associated with maintaining a given level of (Tre).
