The short answer: The mPulse Believe is Sunlighten’s two-person “intelligent” sauna. Sunlighten says its PulseIQ platform controls red light, near, mid and far infrared separately, with six programs (detox, weight loss, heart health, relaxation, muscle recovery, anti-aging) that it says are built from 37 clinical studies. There is no online price: mPulse is quoted by consultant. Sunlighten’s simpler lines list from $2,099 (Solo), $5,099 (Signature) and $5,799 (Amplify). If you want a home infrared sauna, ask what each program actually delivers; the trials on infrared sauna are small and none shows longer life.
Sunlighten’s lines against Clearlight’s Sanctuary 2
Read from the makers’ pages on 29 Sept 2026.
Sunlighten’s Believe page keeps numeric specs (size, weight, electrical, warranty) behind expanders our reader could not open, so confirm them with a consultant. Sunlighten says all models use SoloCarbon heaters with 99% emissivity; we found no independent measurement of that or of EMF.
What the research says
- Heart failure. A 2018 meta-analysis of nine studies found that infrared sauna sessions of the kind used in those studies (15 minutes at 60 C, then a 30-minute rest, five times a week for 2 to 4 weeks) were linked to lower BNP and better ejection fraction in heart-failure patients, with no effect on blood pressure. Moderate to insufficient evidence.
- Healthy women. A 2022 crossover trial of 10 women found an infrared sauna raised body temperature but did not change blood pressure, arterial stiffness or HRV differently from rest.
- Programs. We could not find which 37 studies Sunlighten’s six programs draw on, so we cannot say whether a given program (for example “weight loss”) is backed by trials.
The wider longevity evidence is about traditional saunas; see home saunas: what the studies show.
Who it suits, who should skip it
Pick it if you want separate control of infrared bands, have budget for a consultant-quoted premium unit, and see it as a comfort and routine purchase.
Skip it if you want a proven health intervention, a fixed online price, or the lowest cost: a Solo ($2,099) or Signature ($5,099) costs less than either premium cabin; see also the Clearlight Sanctuary 2, which retailers list at about $7,300 to $7,800. Ask your doctor first if you are pregnant, have heart disease or low blood pressure, or take medicines that affect heat tolerance. Routine details: sauna protocol.
