hyperthermia raises venous oxygen saturation from ~54% to ~88% during a session

Sauna-induced hyperthermia caused a significant increase in venous oxygen saturation (SvO2) from ~54% at baseline to ~88% at the end of the session, indicating substantially improved tissue oxygenation.

What this means for you

When your blood carries more oxygen back from your tissues, it's a sign your body is circulating and delivering oxygen more efficiently. Better tissue oxygenation supports energy production, faster recovery, and the kind of cellular environment where your body can do its best repair work.
