Serum TSH levels were measured after exposing male volunteers to cold, or successively to warmth and to cold, causing clear changes in body temperature. Very moderately heated Finnish sauna bath increased body temperature to about an average of 39 degrees C, and cooling in a relatively warm swimming pool (+25 to +28 degrees C, 30 min) decreased body temperature to below 35 degrees C after sauna, and to about 33 degrees C without sauna. In both cases a slight but significant initial increase of serum TSH was demonstrated. No changes in serum T3 or ETR were seen. The results suggest that a similar mechanism of initial TSH response may exist in humans as has previously been demonstrated in rats.
在男性志愿者暴露于寒冷环境，或先后暴露于温暖环境和寒冷环境（导致体温发生明显变化）后，测量其血清促甲状腺激素（TSH）水平。芬兰桑拿浴进行适度加热可使体温升高至约39摄氏度的平均水平，在相对温暖的游泳池（25至28摄氏度，30分钟）中冷却，桑拿后可使体温降至35摄氏度以下，未进行桑拿时可降至约33摄氏度。在这两种情况下，均显示血清TSH有轻微但显著的初始升高。血清三碘甲状腺原氨酸（T3）或促甲状腺激素释放激素（ETR）未见变化。结果表明，人类可能存在与先前在大鼠中所证明的类似的TSH初始反应机制。
