Title Time and temperature effects on body fluid loss during dives with the open hot-water suit
Bibliographic information July 2005, Vol.76, No.7, Section I, p.655-660. Illus. 13 ref.
Abstract Bodyweight (BW) losses up to 5kg have been observed during diving with open hot-water suits (HWSs). The objective of the two series of dives performed in this study was to examine hormonal, haematological and dehydration effects during shallow HWS diving. Changes in thermal stress, haemoglobin, haematocrit, aldosterone and electrolyte excretion correlated with BW reduction. BW loss during HWS diving is mainly caused by sweating. Dives of 4h produce an isotonic dehydration. Therefore a break for fluid intake is recommended.
