Pricing: €25–50 per session, €100–250 for monthly memberships in larger Paris and Lyon spas. Cabins typically run 50–65 °C far-infrared, with some full-spectrum models in higher-end venues.
The research most-cited for sauna cardiovascular benefit (Laukkanen 2015, 2018) is from traditional Finnish sauna at 80–90 °C, not IR. Direct IR studies (Beever 2009, Ohori 2012) are smaller. The 'detox via sweat' marketing claim is poorly supported in peer-reviewed literature; ask centers that lean heavily on those claims to point to specific studies.
