桑拿浴是一种健康的习惯，与更好的血流动力学功能有关;然而，桑拿浴与心血管和全因死亡率的关系尚不清楚。目的调查桑拿浴的频率和持续时间与心源性猝死（SCD）、致死性冠心病（CHD）、致死性心血管疾病（CVD）和全因死亡率的关系。我们进行了一项前瞻性队列研究（芬兰库奥皮奥缺血性心脏病危险因素研究），样本为2315名来自芬兰东部的中年男性（年龄范围，42-60岁）。基线检查从1984年3月1日至1989年12月31日进行。结果在中位随访20.7年（四分位距18.1-22.6年）期间，发生了190例SCD、281例致死性CHD、407例致死性CVD和929例全因死亡事件。共有601、1513和201名参与者分别报告每周1次、每周2至3次和每周4至7次桑拿浴。桑拿浴频率组、桑拿浴频率组和桑拿浴频率组发生SCD的例数分别为61例（10.1%）、119例（7.8%）和10例（5.0%）。致死性CHD分别为89例（14.9%）、175例（11.5%）和17例（8.5%）;致死性CVD分别为134例（22.3%）、249例（16.4%）和24例（12.0%）;全因死亡事件分别为295例（49.1%）、572例（37.8%）和62例（30.8%）。调整CVD风险因素后，与每周1次桑拿浴的男性相比，每周2至3次桑拿浴的SCD风险比为0.78（95%CI，0.57-1.07），每周4至7次桑拿浴的SCD风险比为0.37（95%CI，0.18-0.75）（趋势P = 0.005）。冠心病、心血管疾病和全因死亡率也有类似的相关性（P趋势
IMPORTANCE Sauna bathing is a health habit associated with better hemodynamic function; however, the association of sauna bathing with cardiovascular and all-cause mortality is not known.OBJECTIVE To investigate the association of frequency and duration of sauna bathing with the risk of sudden cardiac death (SCD), fatal coronary heart disease (CHD), fatal cardiovascular disease (CVD), and all-cause mortality.DESIGN, SETTING, AND PARTICIPANTS We performed a prospective cohort study (Finnish Kuopio Ischemic Heart Disease Risk Factor Study) of a population-based sample of 2315 middle-aged (age range, 42-60 years) men from Eastern Finland. Baseline examinations were conducted from March 1, 1984, through December 31, 1989.EXPOSURES Frequency and duration of sauna bathing assessed at baseline.RESULTS During a median follow-up of 20.7 years (interquartile range, 18.1-22.6 years), 190 SCDs, 281 fatal CHDs, 407 fatal CVDs, and 929 all-cause mortality events occurred. A total of 601, 1513, and 201 participants reported having a sauna bathing session 1 time per week, 2 to 3 times per week, and 4 to 7 times per week, respectively. The numbers (percentages) of SCDs were 61 (10.1%), 119 (7.8%), and 10 (5.0%) in the 3 groups of the frequency of sauna bathing. The respective numbers were 89 (14.9%), 175 (11.5%), and 17 (8.5%) for fatal CHDs; 134 (22.3%), 249 (16.4%), and 24 (12.0%) for fatal CVDs; and 295 (49.1%), 572 (37.8%), and 62 (30.8%) for all-cause mortality events. After adjustment for CVD risk factors, compared with men with 1 sauna bathing session per week, the hazard ratio of SCD was 0.78 (95% CI, 0.57-1.07) for 2 to 3 sauna bathing sessions per week and 0.37 (95% CI, 0.18-0.75) for 4 to 7 sauna bathing sessions per week (P for trend =.005). Similar associations were found with CHD, CVD, and all-cause mortality (P for trend
