Cold Water Immersion Stirring in Hyperthermic Individuals

The best way to cool a very hot person is using cold water immersion, however, the optimization of this technique has not been established. The goal of this study is to determine differences in cooling rates among two types of cold water immersion and passive cooling following immersion.
