Full Spectrum Infrared Sauna

At ETERNA Santa Monica, we keep our Clearlight® full spectrum infrared sauna at 175°F — the hottest in town — for maximum therapeutic effect. Combined with True Wave™ low-EMF/ELF heaters, you receive the deepest, most effective sweat and cellular reset possible, while still staying safe and comfortable.

The Science

Infrared heat penetrates tissues 1.5–2 inches below the skin surface, stimulating circulation, enhancing oxygen delivery, and mobilizing toxins for release through sweat. Clearlight's 700-watt full-spectrum heaters outperform standard 500-watt models, providing a stronger therapeutic range of near, mid, and far infrared light.

Infrared therapy has been shown in clinical studies to:

• Increase mitochondrial activity and ATP production
• Improve cardiovascular conditioning
• Support detoxification of heavy metals and environmental toxins
• Reduce chronic pain and stiffness

Our sauna incorporates double chromotherapy lighting, allowing guests to bathe in colors that influence mood, energy, and nervous system balance.

Benefits of Infrared Sauna

• Deep cellular detoxification
• Skin rejuvenation and collagen support
• Enhanced circulation and lymphatic flow
• Joint and muscle recovery
• Stress reduction and better sleep

Frequency Recommended

• General wellness: 2–4 times per week
• Detox protocols: Daily use for 1–2 weeks, then taper
• Athletic recovery: After workouts, 3–5 times per week

Best Pairings (Stacking)

The sauna is best done as a stand-alone session, giving your body space to sweat and restore.

• Contrast option: Sauna followed by cryotherapy maximizes circulation and resilience.
• Separate days: Alternate with other services (Mindvybe™, Normatec, Body Roller) for full-spectrum benefits without overstressing the system.

When to Use

• Stomach: Light or empty is best — avoid heavy meals before sauna.
• Daytime: Use in the evening to promote restful sleep, or pre-workout to loosen muscles.
• Female cycle: Best avoided during days 1–6 (menstruation), since heat can increase bleeding. Excellent during luteal phase for easing PMS-related cramps and tension.

Who Should Not Use

• Pregnant women
• Those with uncontrolled high blood pressure or heart conditions
• Individuals with severe dehydration or acute illness
• Anyone on medications that impair sweating or thermoregulation

The ETERNA Experience

Private and elevated, our 25-minute sessions combine Clearlight's advanced infrared heaters with full-spectrum red light. The extra-large sauna fits up to three guests or offers ample space for one to fully stretch out — and we don't charge extra for guests. Maintained at 175°F, it delivers Santa Monica's most powerful detox and most rejuvenating sweat.
