10名受试者在24℃至37℃的9种不同水温中进行头部浸泡研究。在每个温度下的浸泡时间为1小时。，在此期间观察不同的体温、脉搏率、血压和VO2[耗氧量/分钟]。在水温低于35.6℃时，尽管热损失的血管舒缩性控制很明显，但中心体温仍有所降低。如果水温为30度，则会增加产热。或更少。36度或更高的水温对受试者施加热应力，导致脉搏率和脉压增加。有人建议，有一个很窄的水温范围（35.0-35.5[度]C）可以被认为是“中性的”。
Ten subjects were studied during head-out immersion in 9 different water temperatures ranging from 24oCto37[degree]C. The period of immersion at each temperature was 1 hr., during which time various body temperatures, pulse rate, blood pressure, and VO2 [oxygen consumption/minute] were observed. In water temperatures less than 35.6oC there was a reduction in central body temperature despite the fact that vasomotor controls of heat loss were evident. Increased heat production was noted if the water temperature was 30[degree]C. or less. Water temperatures of 36[degree]C or more imposed a heat stress on the subject causing an increase in the pulse rate and pulse pressure. It is suggested that there is a very narrow range of water temperature (35.0-35.5[degree]C) which can be considered as "neutral.".
