Abstract

|
|
the bodily dehydration and electrolyte loss from sweating were studied on the effect on bodily physiological ivity in twenty seven healthy men after they had worked for seven hours in the mine where the effective aperature was maintained in 25 to 29˚C. Body flluid loss through body surface unit area, except for that t by kidney pathway, reached 1444.6 cc/M^2 and chloride loss from sweating showed to be reverse in protion. It seemed that the more sweating the miner had, the less chloride concentration the body fluid iwed. The chloride concentration and salt loss from sweating was respectively 21.7 mEq/L and 1.74 gm/M2 l urinary osmolality approached maximum concentrating ability for standard Korean, being 935 mOam/L. The fluid loss was not completly recovered to the level of resting state in spite of 672 cc of water intake (27.6 percent of the fluid loss), and 2.98 per cent of body Nveight was elicited following mine working. In conclusion, the bodily activity due to fluid loss would be considered to drop to the moderate degree, if-these results were compared with those reported by Brown et al.
