Cardiovascular and Other Health Benefits of Sauna Bathing: A Review of A total of 40 studies remained for inclusion in this systematic review. In the data extraction step, one study was excluded since it was essentially a case series with two patients, mistakenly identified as an interventional trial conducted by a key author [73]. The findings of the 9 studies that researched sauna therapy for congestive heart failure (CHF) in adults culminated in the largest and most recent prospective multicentred randomized controlled trial involving 149 patients with advanced CHF that demonstrated small but improved 6-minute walking distances (44.9m SD 49.3m, p < 0.05), reduced cardiothoracic ratios on chest X-ray (1.58%SD 2.81%, p < 0.05) reflecting reduced heart sizes, and improved NYHA (New York Heart Association) classifications of disease (fewer class III and IV patients, p < 0.05) after 2 weeks of sauna therapy, all compared to no significant respective changes in a control group that received standard medical care [31].

Waon therapy improves the prognosis of patients with chronic heart failure. Of the 13 randomized controlled trials (RCTs) identified, only 3 of these studies (involving 343/840 participants) [31, 50, 58] were assessed with having a low overall risk of bias according to the Cochrane Collaboration criteria [71] and a Jadad et al. With the rise of single-cell analysis and omics platforms of analysis such as metabolomics and transcriptomics, especially applied to sweat, blood, urine, saliva, and other human biofluids, the ability to unravel the metabolic pathways at work during sauna or whole-body thermotherapy will certainly improve. Miragem A. All of the sauna interventions were conducted in supervised settings (i.e., in-hospital, rehabilitation hospitals, health centres, university or medical laboratories, and outpatient programs) except Kanji et al. Further study is also needed to determine the optimal frequency and duration of distinct types of sauna bathing for targeted health effects and the specific clinical populations who are most likely to benefit.

Intense short-term heat exposure elevates skin temperature and core body temperature and activates thermoregulatory pathways via the hypothalamus [18] and CNS (central nervous system) leading to activation of the autonomic nervous system. Would you like email updates of new search results? Another 28 studies were excluded due to the intervention being only a single session of sauna and not repeated sauna therapy, which is the stated focus of this review. Now, a sauna cannot be the only thing to bring you to better health, but it can greatly aid you in your quest for a lower weight. Am J Med. Kunutsor S. K., Laukkanen T., Laukkanen J. This is supported by newer, single-cell analysis methods that suggest sauna bathing increases generation of free radicals and reactive oxygenated species along with enhanced antioxidant activities via proposed nitric oxide- (NO-) dependent processes in blood [62] and upregulation of specific HSPs (heat shock proteins) and HSFs (heat shock factors) in semen [27]. Improved Recovery 4. Studies were included for initial review if they were published in English language from January 2000 onwards and involved research in humans undergoing repeated dry sauna sessions with at least one reported health outcome.

Distinct skeletal muscle gene regulation from active contraction, passive vibration, and whole body heat stress in humans. 2015 (n = 10) reported decreased fatigue (p = 0.002) on numerical rating scales and improved scores for anxiety (p = 0.008), depression (p = 0.018), fatigue (p = 0.005), and performance status (p = 0.005) on POMS (profile of mood states) questionnaire after 4 weeks of infrared sauna sessions [55]. In this review, adverse signs and symptoms of both Finnish-style and infrared sauna bathing were reported as mild to moderate heat discomfort and intolerance in 4 of the studies [53, 54, 61, 69], low blood pressure/light-headedness in one study [31], transient leg pain in another study [34], airway irritation in two studies [51, 58], and claustrophobia in one study [51], with no severe adverse symptoms reported in any studies. 2009 used several self-assessed validated scoring tools: Beschwerden-Liste 24-item questionnaire of somatic symptoms, ADS-L/CES-D 20-item questionnaire of general depression, and SF-36 quality of life questionnaire. Of the 906 nonduplicate citations initially identified, 738 were excluded after a review of the abstracts. Is Sauna Good for Joint Pain?

Are Saunas Good for Your Lungs and Respiratory Health? On a cellular level, acute whole-body thermotherapy (both wet and dry forms) induces discrete metabolic changes that include production of heat shock proteins, reduction of reactive oxygenated species, reduced oxidative stress and inflammation pathway activities, increased NO (nitric oxide) bioavailability, increased insulin sensitivity, and alterations in various endothelial-dependent vasodilatation metabolic pathways [22]. Cardiovascular disease- (CVD-) related sauna studies. Hydrothermotherapy in prevention and treatment of mild to moderate After 3 months of repeated sauna (15-min saunas twice weekly), the investigators reported reduced sperm counts (93 27.0 106 versus 223 52.8 106, p < 0.001); reduced sperm concentrations (31 13.1 106/ml versus 89 29.3 106/ml, p < 0.001); fewer motile sperm (36.1 3.6% versus 58.0 7.6%, p < 0.01); abnormal sperm parameters [decrease in normal histone-protamine replacement (p < 0.05); abnormal chromatin condensation (p < 0.05); altered mitochondrial function (p < 0.01)]; upregulation of various heat-stress genes [HIF-1 (p < 0.001), KDR (p < 0.001), FLT1 (p < 0.001), and VEGF (p < 0.001)]; and upregulation of HSPs (heat shock proteins) and HSFs (heat shock factors) [HSP90 (p < 0.001), HSP70 (p < 0.001), HSF1 (p < 0.001), HSF2 (p < 0.001), and HSFY (p < 0.001)].
