TY - JOUR T1 - Far-infrared saunas for treatment of cardiovascular risk factors JF - Canadian Family Physician JO - Can Fam Physician SP - 691 LP - 696 VL - 55 IS - 7 AU - Richard Beever Y1 - 2009/07/01 UR - http://www.cfp.ca/content/55/7/691.abstract N2 - OBJECTIVE To review the literature about the health benefits of far-infrared sauna (FIRS) use. QUALITY OF EVIDENCE A search of Web of Science, EBSCO, Ovid MEDLINE, Ovid HealthSTAR, and EMBASE using the terms far-infrared and sauna, refined by limiting the search to studies of humans published in English, yielded 9 relevant papers (level I or level II evidence). MAIN MESSAGE Far-infrared saunas are approved by the Canadian Standards Association and are sold to the public. The manufacturers claim numerous health benefits; however, the published evidence to substantiate these claims is limited. Four papers support the use of FIRS therapy for those with congestive heart failure and 5 papers support its use for those with coronary risk factors. CONCLUSION There is limited moderate evidence supporting FIRS efficacy in normalizing blood pressure and treating congestive heart failure; fair evidence, from a single study, supporting FIRS therapy in chronic pain; weak evidence, from a single study, supporting FIRS therapy in chronic fatigue syndrome; weak evidence, from a single study, supporting FIRS therapy for obesity; and consistent fair evidence to refute claims regarding the role of FIRSs in cholesterol reduction.
