Short answer: Safe use is model-specific. The exact manual controls surface, electrical setup, clothing or liner, controls, duration, temperature, cleaning, storage, and contraindications.

Pre-use checks

Stop and do not continue

Stop for equipment damage or concerning symptoms such as dizziness, faintness, confusion, chest pain, unusual shortness of breath, skin injury, or inability to cool normally. Relevant health conditions and medications require qualified guidance.

Bottom line: Manufacturer instructions and health context control; there is no universal beginner dose.

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.
