Sunlighten mPulse Believe

The science

Infrared saunas heat the body directly via far-infrared radiation at lower air temperatures (110-150F) than traditional saunas, with the mPulse layering near-infrared (~880nm) and mid-infrared emitters plus red LEDs; the core physiological effect — heat stress, sweating, heart-rate elevation, transient vasodilation — is real and shared with all saunas. The strongest human evidence for sauna benefits (cardiovascular mortality, dementia associations from Finnish cohorts) comes from traditional hot saunas, not infrared; infrared-specific evidence is thinner — small trials on blood pressure, heart-failure adjunct therapy (Waon), subjective recovery. Wavelength-specific whole-body claims ("targeting" detox, weight loss, cellular repair at distinct depths) outrun the data; "detoxification" via sweat is physiologically marginal. Sell heat, relaxation, and recovery ritual; those are real.

Patented tech

SoloCarbon is Sunlighten's patented carbon-panel far-infrared heater with genuinely high far-IR emissivity (claimed 95-99%); the mPulse's 3-in-1 heaters add discrete near/mid-IR elements orchestrated by an Android control platform with preset "wellness programs" — real hardware, but the programs are essentially timed heater-mix presets with wellness branding.

Origin

Cabins manufactured overseas (historically China) with US headquarters, design, and distribution in Overland Park, Kansas — an American brand, not American manufacture.

Best-fit practice

Wellness franchises and contrast-therapy studios building sauna-plus-cold-plunge suites, medspas adding a low-risk recurring-revenue room, boutique fitness/recovery operators. The broadest demographic in wellness: 25-70, skewing female relative to cryo, sold on stress relief and ritual. If your buyer profile is a dedicated sauna-studio franchise, note Perspire standardized on Clearlight — cross-shop both.

Medical director & delegation

Not required anywhere; the liability realities are heat protocols — posted time/temperature limits, hydration guidance, emergency call buttons in private rooms, documented cleaning — plus honest marketing, since overheated unattended clients and detox claims are the two ways sauna studios get sued.

Contraindications & screening

Pregnancy, unstable cardiovascular disease, recent MI, severe orthostatic hypotension, alcohol impairment, medications impairing thermoregulation (diuretics, anticholinergics), MS and other heat-intolerant conditions; children and implanted-device clients need physician sign-off.

Warranty & service

Lifetime warranty on SoloCarbon heaters with ~7 years wood/electrical and 5 on controls (commercial-use terms are shorter — get the commercial schedule in writing); installation needs a dedicated 20-amp circuit per cabin, modest ventilation, assembly in hours; 6-12 week lead times are the common complaint.

Resale & used market

Genuinely strong consumer demand for used Sunlighten cabins — 50-70% of retail on 2-4 year-old units — though commercial wear discounts faster than home units; the brand name is what you're reselling.
