Pathophysiological effects of exposure to Finnish sauna (80 to 90 C, 30 to 40% relative humidity) were investigated in 60 volunteers--33 men and 27 women aged between 18 and 63 years. The volunteers entered the sauna after a rest period of 20 min, and remained there for 20 min or until they suffered discomfort. Weight, height, rectal and skin temperatures, blood pressure, heart and respiratory rates and ECG were recorded 20 min prior to the sauna, during the sauna, and 20 min after leaving the sauna. Marked physiological changes appeared in the first few minutes in the sauna without any prodromal warning. At the 20th min the mean heart rate was 143 +/- 25 (SD) beats/min (greater than 160 beats/min in 32% of the subjects). Mean rectal temperature was 38.6 +/- 0.6 (SD) C (greater than 39 C in 22%): mean skin temperature was 40.4 +/- 1 (SD) C (greater than 40 C in 35%); mean systolic blood pressure was 130.5 +/- 26.6 (SD) mm Hg (greater than 160 mm Hg in 17%); and mean diastolic pressure was 66.6 +/- 15.9 (SD) mm Hg (greater than 50 mm Hg in 17%). The mean total sweat loss was 457 +/- 264 (SD) g. Three subjects experienced syncope, and one developed an anginal attack; ECG changes suggestive of coronary insufficiency were recorded. No decrease in blood pressure occurred in patients with preexisting high blood pressure. It is concluded that sauna bathing involves dangers to the bather's health, which may appear suddenly, without prodromal warning signs.
对60名志愿者（33名男性和27名女性，年龄在18至63岁之间）进行了暴露于芬兰桑拿（80至90摄氏度，相对湿度30至40%）的病理生理效应研究。志愿者在休息20分钟后进入桑拿房，并在那里停留20分钟或直至感到不适。在进入桑拿房前20分钟、桑拿期间以及离开桑拿房后20分钟记录体重、身高、直肠温度和皮肤温度、血压、心率和呼吸频率以及心电图。在桑拿房的最初几分钟内出现了明显的生理变化，且无任何前驱警告。在第20分钟时，平均心率为143±25（标准差）次/分钟（32%的受试者心率大于160次/分钟）。平均直肠温度为38.6±0.6（标准差）摄氏度（22%的受试者温度大于39摄氏度）；平均皮肤温度为40.4±1（标准差）摄氏度（35%的受试者温度大于40摄氏度）；平均收缩压为130.5±26.6（标准差）毫米汞柱（17%的受试者血压大于160毫米汞柱）；平均舒张压为66.6±15.9（标准差）毫米汞柱（17%的受试者血压大于50毫米汞柱）。平均总出汗量为457±264（标准差）克。3名受试者发生晕厥，1名出现心绞痛发作；记录到提示冠状动脉供血不足的心电图变化。既往有高血压的患者血压未降低。结论是，桑拿浴对沐浴者健康存在危险，且可能突然出现，无前驱警示迹象。
