在芬兰桑拿浴中的三个热暴露期间，对八名健康的年轻男子进行了研究：80 ℃。C干球（80 D）和100 ℃。C干球（100 D）温度，直到主观不适，并在80 ℃。C干热，变得潮湿[80 DH），直到主观疲惫。口腔温度升高1.1 ℃。温度为80 ℃，1.9 ℃。在100 ℃和3.2 ℃下，80 ℃。80 D时心率增加约60%，100 D时增加约90%，80 DH时增加约130%。血浆去甲肾上腺素在80 D时增加约100%，100 D时增加约160%，80 DH时增加约310%。肾上腺素没有变化。血浆催乳素在80 D时增加2倍，在100 D时增加7倍，在80 DH时增加10倍。100 D时β-内啡肽免疫反应性、100 D和80 DH时促肾上腺皮质激素（ACTH）、100 D时生长激素和80 DH时睾酮的血液浓度也增加，但80 D和100 D时皮质醇下降。血浆前列腺素E2和血清血栓素B2水平无变化。在三个研究期内，观察到心率、血浆去甲肾上腺素、ACTH和催乳素与热暴露相关的模式。
Eight healthy young men were studied during three periods of heat exposure in a Finnish sauna bath: at 80.degree. C dry bulb (80 D) and 100.degree. C dry bulb (100 D) temperatures until subjective discomfort, and in 80.degree. C dry heat, becoming humid [80 DH) until subjective exhaustion. Oral temperature increased 1.1.degree. C at 80 D, 1.9.degree. C at 100 D and 3.2.degree. C at 80 DH. Heart rate increased about 60% at 80 D, 90% at 100 D and 130% at 80 DH. Plasma noradrenaline increased about 100% at 80 D, 160% at 100 D and 310% at 80 DH. Adrenaline did not change. Plasma prolactin increased 2-fold at 80 D, 7-fold at 100 D and 10-fold at 80 DH. Blood concentrations of the beta-endorphin immunoreactivity at 100 D, adrenocorticotropic hormone (ACTH) at 100 D and 80 DH, growth hormone att 100 D and testosterone at 80 DH also increased, but cortisol at 80 D and 100 D decreased. The plasma prostaglandin E2 and serum thromboxane B2 levels did not change. Patterns related to heat exposure were observed for heart rate, plasma noradrenaline, ACTH and prolactin in the three study periods.
