Prediction of Water Requirements to Replace Sweat Losses

Abstract

The Shapiro sweat prediction equation (OSE) was formulated more than two decades ago as: msw (g m[expn -2] h[expn -1]) = 27.9 E(sub req) (Emax)[expn -0.455], where Ereq is required evaporative heat loss and Emax is maximum evaporative power of the environment. Although OSE was developed for a limited set of conditions, in practice it is often used outside its boundaries to estimate fluid requirements and generate guidance in military, public health, occupational and sports medicine settings. Military (NATO) and public health (IOM) reports have expressed a need for improved sweating rate prediction models that calculate hourly and daily water needs.
