The prognosis for exertional heat stroke depends upon the product of length of time the core temperature is elevated and the degree of elevation. The athlete with EHS who is discovered promptly and efficiently cooled will most likely survive the episode with little if any residual. In contrast, the athlete who has delayed presentation for treatment, especially if the area under to cooling curve is > 60 degree-minutes (centigrade), will have a complicated and often fatal course. Conductive cooling methods with ice or cool water immersion or rotating ice water cooled towels provide rapid and consistent whole body temperature reduction that is both organ and life saving. Recognition depends on a high index of suspicion on the part of athletes, coaches, and onsite medical personnel. In high risk conditions, athletes should "buddy up" to watch for subtle changes that can signal the onset of EHS.
