Water-immersion treatments for exertional hyperthermia

Ice--cold water immersion can rapidly extract heat from hyperthermic patients. However, access to ice or cold water is limited when in the field, and some researchers have concerns regarding the possible adverse impact of the sudden cold-water immersion of hyperthennic individuals. We hypothesised that wanner-water immersions could still facilitate rapid cooling in profoundly hypertbennic people, and this would be due to less powerful cutaneous vasoconstrictor responses. These hypotheses were tested in two separate experiments
