VIVEIROS, Jacqueline de Paula; MEYER, Flávia and KRUEL, Luiz Fernando Martins. Cold water immersion to the control of exertional heat illness. Rev Bras Med Esporte [online]. 2009, vol.15, n.4, pp. 311-315. ISSN 1806-9940. http://dx.doi.org/10.1590/S1517-86922009000500016.
The incapacity of dissipating heat generated by muscular activity hampers performance and increases predisposition to physical injuries. Exertional heat illness (HTE) harms health and is associated with morbidity and mortality of individuals in different occupational and athletic activities. Studies on the efficiency of body cooling methods have recommended cold-water immersion for the treatment of HTE. Its use in the initial minutes of post-hyperthermia seems to be the best recommendation to reduce the time central temperature remains high. Maintenance of the infrastructure needed to perform this procedure should be considered in physical activities and environmental conditions in which the individuals are more prone to HTE. The cooling rates observed through water immersion in different water temperatures may serve as reference to the control of HTE procedure duration. This review analyses the recommendation of cold-water immersion as a body cooling procedure for management of HTE.
