Infrared & Traditional Saunas
Home saunas come in two forms: traditional cabins that heat the air to 80–100°C, and infrared cabins that run cooler (typically 45–60°C) while heating the body directly with infrared emitters.
What published research reports
The 2018 systematic review of regular dry sauna bathing reported mostly beneficial or neutral findings across small studies — blood pressure, heart-failure measures, some pain conditions — with rare adverse events in healthy users, and noted that most published evidence concerns traditional Finnish-style saunas, with fewer and smaller studies on infrared cabins. The Finnish cohort study in JAMA Internal Medicine (2015) linking frequent sauna use to lower cardiovascular and all-cause mortality was likewise conducted with traditional saunas. The review lists unstable heart disease and pregnancy among situations where medical advice is recommended first.
