How do far-infrared saunas work?

Far-infrared saunas provide a gentle, soothing warmth that warms the body directly, rather than just heating the surrounding air. Unlike traditional high-heat saunas, far-infrared wavelengths deeply penetrate the skin, delivering a comforting heat that may support circulation (Miyamoto et al., 2018, PMC6263304), encourage muscle relaxation (Beever, 2009, PMC2920462), and promote a deep, refreshing sweat (Gagnon et al., 2016, PubMed 26857237).

 

Research suggests that infrared heat works in harmony with the body's natural thermoregulation process, (Scoon et al., 2007, PubMed 17267744), gently encouraging perspiration while supporting cardiovascular function (Kihara et al., 2004, PubMed 15522955) and assisting in post-activity recovery (Szygula et al., 2014, PubMed 25705824). Unlike steam or dry heat saunas, far-infrared saunas create a more comfortable, deeply relaxing environment, allowing you to experience warmth that envelops and restores.
