新出现的证据表明桑拿浴对心血管系统有益。然而，桑拿浴对心血管功能参数和血液生物标志物的影响尚不确定。我们的目的是调查桑拿浴是否会引起动脉僵硬度，血压（BP）和几种血液生物标志物的变化。我们进行了一项实验性研究，包括102名参与者（平均年龄（SD）：51.9（9.2）岁，56%男性），他们至少有一个心血管危险因素。参与者暴露于单个桑拿时段（持续时间：30分钟;温度：73摄氏度;湿度：10-20%）。在恢复前、恢复后即刻和恢复后30分钟收集心血管和血液参数。桑拿前平均颈动脉-股动脉脉搏波速度为9.8（2.4）m/s，桑拿后立即降至8.6（1.6）m/s（p < 0.0001）。桑拿后平均收缩压从137（16）mmHg降至130（14）mmHg（p < 0.0001），舒张压从82（10）mmHg降至75（9）mmHg（p < 0.0001）。与桑拿前水平相比，恢复30分钟后的收缩压仍较低。桑拿浴期间血液学变量有显着变化。从桑拿至恢复期，血浆肌酐水平略有升高，而钠和钾水平保持不变。这项研究表明，桑拿浴30分钟对动脉硬度，血压和一些血液生物标志物有有益的影响。这些发现可能为桑拿浴与降低心血管结局风险之间的新兴关联提供新的见解。
Emerging evidence suggests beneficial effects of sauna bathing on the cardiovascular system. However, the effects of sauna bathing on parameters of cardiovascular function and blood-based biomarkers are uncertain. We aimed to investigate whether sauna bathing induces changes in arterial stiffness, blood pressure (BP), and several blood-based biomarkers. We conducted an experimental study including 102 participants (mean age (SD): 51.9 (9.2) years, 56% male) who had at least one cardiovascular risk factor. Participants were exposed to a single sauna session (duration: 30 min; temperature: 73 degrees C; humidity: 10-20%). Cardiovascular as well as blood-based parameters were collected before, immediately after, and after 30-min recovery. Mean carotid-femoral pulse wave velocity was 9.8 (2.4) m/s before sauna and decreased to 8.6 (1.6) m/s immediately after sauna (p < 0.0001). Mean systolic BP decreased after sauna exposure from 137 (16) to 130 (14) mmHg (p < 0.0001) and diastolic BP from 82 (10) to 75 (9) mmHg (p < 0.0001). Systolic BP after 30 min recovery remained lower compared to pre-sauna levels. There were significant changes in hematological variables during sauna bathing. Plasma creatinine levels increased slightly from sauna until recovery period, whereas sodium and potassium levels remained constant. This study demonstrates that sauna bathing for 30 min has beneficial effects on arterial stiffness, BP, and some blood-based biomarkers. These findings may provide new insights underlying the emerging associations between sauna bathing and reduced risk of cardiovascular outcomes.
