Best Infrared Sauna and Sauna Blanket UK (2026): EMF and Materials Checked
Quick answer
For a sauna blanket, Bon Charge (£549) shares the most materials testing, while MiHIGH (£140) is the best budget option. No blanket publishes EMF figures. For research-backed heat, a traditional sauna such as the Finnmark barrel is closest to the studies. Clearlight is the only infrared cabin we found that publishes EMF readings.
Our picks
Bon Charge Infrared Sauna Blanket
BON CHARGE
- • Cites SGS 197-substance screen and RoHS certificate
- • 25 to 80°C
Honest caveat: The lining is waterproof PVC, which is the opposite of what many ’cleaner materials’ buyers want, and the full SGS report is not published on the page. The ’low EMF’ and ’EMF shielding’ claims have no numbers. Warranty is only one year.
BON CHARGE
MiHIGH Infrared Sauna Blanket
MiHIGH
- • £140 on sale (was £315)
- • CE marked, no UKCA listed
Honest caveat: The product page gives no maximum temperature, no EMF figures and no materials test report, so its low-EMF and fabric claims are unverified. No UKCA mark is listed. Like every blanket, it encloses your body in plastic-faced layers, so air it out before first use.
MiHIGH
STYLPRO Infrared Sauna Blanket
STYLPRO
- • £199 at Currys, also at Argos and Holland & Barrett
- • 35 to 80°C, 10 heat settings
Honest caveat: The ’EMF-shielding technology’ claim comes with no measurements. Materials include PU and ABS plastic, and there is no off-gassing or substance test report. Stock at Currys showed as ’checking’ when we looked.
STYLPRO
HigherDOSE Infrared Sauna Blanket
HigherDOSE
- • £564 at Free People UK
- • Polyurethane shell, wipe clean
Honest caveat: HigherDOSE’s UK domain now redirects to its US site, and the Free People page contains a conflicting ’US only’ shipping note, so confirm UK delivery and warranty before buying. ’Extremely low EMF’ is stated without any figures, and the crystal and clay layers have no evidence of added benefit.
HigherDOSE
LUMI Therapy Sauna PRO (1 Person)
LUMI Therapy
- • £2,799 (was £3,499)
- • Hemlock wood, carbon far-infrared panels
Honest caveat: The page gives no EMF figures and no CE or UKCA details, and the warranty is only one year, which is short for a £2,800 appliance. It draws up to 2,150W, so check your socket and circuit with an electrician.
LUMI Therapy
Finnmark Micro Thermowood Barrel Sauna (2 Person)
Finnmark Sauna
- • £5,371 with 6kW electric heater (£3,995 kit only)
- • 40mm thermally modified spruce
Honest caveat: It is an uninsulated outdoor structure, so heat-up is slower in a British winter, and a 6kW heater needs a dedicated hardwired supply. The timber warranty is two years. You assemble it yourself or pay for installation.
Finnmark Sauna
Clearlight Sanctuary 1 Person Infrared Sauna
Clearlight Saunas UK
- • Publishes EMF readings (brand-measured)
- • FSC-certified okoume wood
Honest caveat: The EMF figures are the brand’s own, with no named lab, and the page contradicts itself (calling 3 mG a WHO ’threshold’ while listing 7 to 8 mG at the front heaters). The UK site shows ’request pricing’; £8,999 is the listed store price at the time of checking. The warranty does not cover on-site labour.

Do infrared sauna blankets actually work?
A sauna blanket is a heated sleeping-bag style wrap with your head outside. It will raise your skin and body temperature and make you sweat. Whether it gives the same benefits as a sauna is unknown: the large studies linking sauna use to heart health used traditional Finnish saunas, and the infrared trials used sit-in cabins, mainly in heart failure patients. We found no controlled trials on blankets themselves. Read our sauna benefits evidence guide for the full picture.
So treat a blanket as a relaxing heat session, not a medical device. If you want to match the research most closely, a traditional sauna is the better bet. If you want infrared, a cabin is closer to the trial setups than a blanket.
How we chose
We looked for products sold in GBP to UK buyers, on a brand UK store or a major UK retailer, checked in October 2026. We then scored each on:
- EMF data: actual measured figures with units and distances, not just "low EMF".
- Materials: what touches your skin and what heats up, and whether there is any substance or emissions test.
- Electrical marking: UKCA, CE or third-party approval.
- Temperature control: a stated range and settings.
- Warranty: length and what it covers.
No product publishes independent EMF test reports, and no blanket publishes off-gassing (VOC emissions) data, so no pick scores "strong".
What do EMF readings mean?
EMF here means the low-frequency magnetic field made by electric current in the heating wires. Brands quote it in milligauss (mG); UK and WHO guidance use microtesla (µT). 10 mG equals 1 µT.
- UKHSA says background levels in UK homes are usually 0.01 to 0.2 µT (0.1 to 2 mG), and up to a few tens of µT close to appliances.
- The international public guideline that UKHSA follows is set far higher, at 100 µT (1,000 mG) at 50 Hz.
- The "3 mG" figure sellers call a WHO threshold is not a safety limit. It comes from studies that found a weak association with childhood leukaemia where a child's average home exposure was above 0.3 to 0.4 µT. UKHSA says the evidence is not strong enough to conclude magnetic fields cause it.
In practice, a sauna's magnetic field drops sharply within a few centimetres. Measured figures with distances are a sign of a transparent brand. "Zero EMF" or "EMF shielding" with no numbers tells you nothing.
What about materials and off-gassing?
Most blankets use a PU (polyurethane) outer, and several have a PVC inner lining for waterproofing. Heated plastics can release a smell when new. No blanket we checked publishes VOC (volatile organic compound) test data. Air any new blanket out, run it empty on a low setting once with the windows open, wear cotton clothing and use a cotton insert or towel. For cabins, solid timber and FSC certification are better signs than glued panels, but FSC covers forestry, not emissions.
Bon Charge Infrared Sauna Blanket: best blanket for test data
Bon Charge is the only blanket brand we found that cites a third-party substance screen (SGS, 197 substances including formaldehyde) alongside a RoHS certificate and SAA electrical approval. It runs 25 to 80°C and sells in GBP from a UK storefront at £549. Caveat: the lining is PVC, the SGS report is not published in full, EMF claims have no numbers, and the warranty is one year.
MiHIGH Infrared Sauna Blanket: best budget blanket
At £140 (down from £315), this CE-marked blanket from a long-running UK seller is the cheapest credible way to try home heat sessions. It fits users up to 196cm. Caveat: no stated maximum temperature, no EMF figures and no materials testing; "toxin-free fabrics" is an unverified claim.
STYLPRO Infrared Sauna Blanket: best for high-street buying
Sold at Currys for £199 and also at Argos and Holland & Barrett, so returns are simple. It lists a 35 to 80°C range, 10 settings and a one-year guarantee. Caveat: "EMF-shielding technology" has no measurements, and it is made of ABS plastic, Oxford fabric and PU with no test reports.
HigherDOSE Infrared Sauna Blanket: the famous one
The brand most people search for, listed at £564 by Free People UK. Polyurethane shell, eight heat levels. Caveat: HigherDOSE's UK site now redirects to its US store, the retailer page has a conflicting shipping note, and "extremely low EMF" has no figures. Confirm UK delivery and warranty before buying. Crystal and clay layers have no evidence of added benefit.
LUMI Therapy Sauna PRO: best mid-price infrared cabin
A one-person hemlock cabin with carbon far-infrared panels, 30 to 65°C, at £2,799. Sitting upright in a cabin is closer to the infrared trial setups than lying in a blanket. Caveat: no EMF figures, no UKCA or CE details on the page, and only a one-year warranty. It draws up to 2,150W.
Finnmark Micro Thermowood Barrel Sauna: best traditional sauna
If you want what the Finnish studies looked at, this is it: a two-person outdoor barrel in 40mm thermally modified spruce (heat and steam treated, not chemically preserved), £5,371 with a 6kW electric heater or £3,995 without. Caveat: uninsulated, so slower to heat in winter; needs garden space, a hardwired supply and assembly; two-year timber warranty.
Clearlight Sanctuary 1: best for published EMF data
The only product here with actual magnetic field figures: 1.5 mG (0.15 µT) at the far-infrared heater surface and 7 to 8 mG at the front full-spectrum heaters, falling to near zero within about 10cm. FSC okoume wood, UK 13A plug and a 25-year residential parts warranty. Caveat: figures are the brand's own, with no named lab; the page calls 3 mG a WHO threshold, which it is not. Listed at £8,999; the UK site asks you to request a quote.
What should you avoid?
- "Detox" and calorie claims. Sweat is not a meaningful route for removing pollutants, according to researchers who estimated it, and sauna weight loss is water.
- "Zero EMF" or "EMF shielding" with no numbers. Ask for mG or µT figures and the distance measured.
- Unbranded listings with no UK seller, no UKCA or CE marking and no warranty. A heating product you lie inside should come from someone accountable.
- Using a blanket while drinking, pregnant, or with a heart condition without medical advice. NHS guidance notes overheating, dehydration and fainting as reasons to avoid saunas in pregnancy.
Remember that UKCA and CE marks are mostly self-declared by the manufacturer, not proof of independent testing.
Bottom line
A sauna blanket is a convenient way to get hot and sweaty at home, but there is no direct research on blankets. If test data matter most, Bon Charge shares the most. If budget matters, MiHIGH is the cheapest credible option. For the closest match to the research, a traditional sauna like the Finnmark barrel is the better buy, and Clearlight is the only infrared option that publishes EMF readings.
Frequently asked questions
Are infrared sauna blankets worth it?
+
They are worth it if you want a convenient, relaxing heat session at home and have limited space. They are not proven to deliver the heart benefits linked to traditional saunas, because no controlled trials have tested blankets directly. If research-backed benefit is your main goal, regular use of a traditional sauna, at home or at a gym, is the better-supported option.
Is the EMF from a sauna blanket dangerous?
+
There is no evidence that it is. UK homes typically measure 0.01 to 0.2 microtesla, and the public guideline is 100 microtesla. Sauna magnetic fields drop quickly within a few centimetres. The 3 mG figure some brands call a limit comes from a weak, unproven association with average childhood home exposure, not a safety threshold. Prefer brands that publish measured figures with distances.
Do sauna blankets give off chemicals?
+
They can smell when new, because they are made from heated plastics such as PU and sometimes PVC. None we checked publishes VOC emissions testing. Bon Charge cites an SGS screen of 197 substances, the most data we found. Air a new blanket out, run it empty with windows open, and use a cotton insert or wear cotton clothing.
Sauna blanket or infrared sauna cabin: which is better?
+
A cabin is closer to the setups used in infrared sauna trials, where people sit upright with their whole body in warm air. Blankets are cheaper and fold away but keep your head out and wrap you in plastic layers. If you have the space and budget, a cabin or a traditional sauna is the better choice.
How hot does a sauna blanket get?
+
Most list a maximum of 60 to 80°C at the heating panels, though your skin will not reach that. Bon Charge and STYLPRO both list 80°C. Start at a lower setting for 15 to 20 minutes, drink water, and stop if you feel dizzy or unwell. Avoid using one if you are pregnant or have been drinking.
Do I need an electrician for a home sauna?
+
Blankets and many one-person infrared cabins use a standard 13A plug, though high-wattage cabins may need a dedicated circuit. Traditional saunas with 6kW or larger heaters need a hardwired supply installed by a qualified electrician. Always check the wattage and installation instructions before buying.
