An Overview of the Health and Fitness Benefits From Sauna Exposure
桑拿暴露对健康与健身益处的概述
📄 英文摘要 English Abstract
This review provides an overview of the health and fitness benefits attributed to sauna exposure. The specific focus explores muscle performance and flexibility, heat acclimation for performance, cardiovascular and respiratory health parameters, all-cause mortality, endocrine response, inflammatory modulators, and exercise recovery. The overarching mechanisms underpinning the health and fitness benefits attributed to sauna use stem from hyperthermia, which activates thermoregulatory cardiovascular, neuroendocrine, and cytoprotective responses that promote homeostasis and adaptation to stress. Muscle performance improvements are attributed to plasma volume expansion, enhanced thermoregulatory efficiency, and upregulation of heat shock proteins. These adaptations enhance muscle contractility, strength, and rate of force development. Flexibility gains are linked to increased tissue temperature and muscle relaxation. Sauna-induced heat acclimation improves cardiovascular stability and core temperature regulation, benefiting athletes and tactical professionals operating in hot environments. Cardiorespiratory benefits include improved VO₂max, reduced blood pressure, and favorable lipid profiles, particularly when sauna is combined with exercise. Moreover, regular sauna use has been associated with reduced incidence of cardiovascular disease, dementia, and respiratory conditions. Sauna exposure also facilitates exercise recovery by reducing muscle soreness and supporting neuromuscular performance, especially with infrared sauna use. Hormonal and molecular responses include modulation of cortisol, growth hormone, testosterone, and cytokines, contributing to reduced inflammation and enhanced cellular repair. However, sauna use is not without risks. Adverse events such as syncope, slip and fall injuries, and burns highlight the need for safety protocols and individualized precautions. Despite promising outcomes, variability in sauna parameters (e.g., temperature, duration, frequency) limits dosing standardization. Despite dosing heterogeneity among studies, sauna exposure represents an evidence-based modality for enhancing health, wellness, and performance. Future research should refine dosing strategies and expand clinical applications.

Background: This review provides an overview of the health and fitness benefits attributed to sauna exposure. The specific focus explores muscle performance and flexibility, heat acclimation for performance, cardiovascular and respiratory health parameters, all-cause mortality, endocrine response, inflammatory modulators, and exercise recovery. The overarching mechanisms underpinning the health and fitness benefits attributed to sauna use stem from hyperthermia, which activates thermoregulatory cardiovascular, neuroendocrine, and cytoprotective responses that promote homeostasis and adaptation to stress.

Results: Muscle performance improvements are attributed to plasma volume expansion, enhanced thermoregulatory efficiency, and upregulation of heat shock proteins. These adaptations enhance muscle contractility, strength, and rate of force development. Flexibility gains are linked to increased tissue temperature and muscle relaxation. Sauna-induced heat acclimation improves cardiovascular stability and core temperature regulation, benefiting athletes and tactical professionals operating in hot environments.

背景:
本综述概述了桑拿暴露对健康和健身的益处。具体关注肌肉表现与柔韧性、热适应对运动表现的影响、心血管与呼吸健康参数、全因死亡率、内分泌反应、炎症调节因子以及运动恢复等方面。桑拿使用所赋予的健康和健身益处的核心机制源于高热，高热激活了体温调节性心血管、神经内分泌和细胞保护性反应，从而促进体内平衡和对压力的适应。
方法:
不适用——综述类文章
结果:
肌肉表现的改善归因于血浆容量扩张、体温调节效率增强以及热休克蛋白的上调。这些适应性变化增强了肌肉收缩力、力量和力量发展速率。柔韧性的提升与组织温度升高和肌肉放松有关。桑拿诱导的热适应改善了心血管稳定性和核心体温调节，有利于在高温环境中运动的运动员和战术专业人员。心肺益处包括最大摄氧量（VO₂max）提高、血压降低以及血脂谱改善，尤其是将桑拿与运动相结合时。此外，定期使用桑拿与心血管疾病、痴呆和呼吸系统疾病发病率降低相关。桑拿暴露还通过减轻肌肉酸痛和支持神经肌肉表现来促进运动恢复，尤其是使用红外线桑拿时。激素和分子反应包括皮质醇、生长激素、睾酮和细胞因子的调节，有助于减轻炎症并增强细胞修复。然而，桑拿使用并非没有风险。晕厥、滑倒摔伤和烧伤等不良事件凸显了安全规程和个体化预防措施的必要性。
数据摘要:
尽管结果前景乐观，但桑拿参数（如温度、持续时间、频率）的变异性限制了剂量标准化。摘要中未提供具体的定量结果或关键统计数据。
结论:
尽管各研究之间存在剂量异质性，桑拿暴露仍是一种循证的健康、保健和运动表现增强方式。未来研究应优化剂量策略并拓展临床应用。
实际意义:
桑拿诱导的热适应改善了心血管稳定性和核心体温调节，有利于在高温环境中运动的运动员和战术专业人员。桑拿暴露还通过减轻肌肉酸痛和支持神经肌肉表现来促进运动恢复，尤其是使用红外线桑拿时。
