Short answer: Treat first use as an equipment and exit check, not a heat-tolerance test. Follow the exact manual; no universal first-session temperature or duration is established.
Verify before use
| Area | Verify |
|---|---|
| Equipment | Damage, controller, cord, plug, approved surface, orientation, electrical requirements |
| Body contact | Approved clothing, liner, head and arm position, contraindications |
| Controls | Model-specific start, stop, and emergency exit |
| Aftercare | Cooldown, cleaning, complete drying, storage |
Do not copy another brand's settings or combine first use with alcohol, impairing substances, exercise stress, or another temperature extreme.
Bottom line: The exact model instructions, symptoms, and qualified guidance control. Stop immediately for concerning symptoms or equipment problems.
Evidence and limits
Sauna studies vary by sauna type, population, frequency, duration, and outcome. Dry-sauna findings do not establish a consumer infrared-blanket dose, schedule, or health result.
