Best Infrared Sauna Blanket UK 2026

An infrared sauna blanket gives you most of the sweat of a sauna session without building a sauna. You lie inside it, zip up, and far infrared (the longer-wavelength infrared band that warms your body directly rather than heating the air around you) raises your core temperature for 30 to 60 minutes.
Four blankets dominate the UK market: Bon Charge, HigherDOSE, Sun Home and MiHIGH. They look similar, but they split sharply on price, EMF (electromagnetic field) transparency, warranty and how easy they are to actually buy and return in the UK. This guide ranks them on the things that matter once the marketing is stripped away. For the bigger decision of a blanket versus a full cabin, see our infrared vs traditional sauna comparison.

The picks in detail

- Lowest published verified EMF in this group (0.16mG vs a 2.0mG safety threshold)
- Widest temperature band (25-80°C) and fits users up to 6'7"
- Stocked and shipped from the UK, so no import duty or long returns
Cons
- Joint most expensive option at £549
- Only a one-year warranty at a premium price point
HigherDOSE Infrared Sauna Blanket V4
Bottom line. The premium-brand pick if you want the best-known name and a full wrap shape.

- Full 180 x 180cm wrap rather than a fixed bag shape
- Publishes third-party EMF test data, a trust signal many rivals skip
- Strong resale and brand recognition if you later sell it on
Cons
- Joint most expensive at £549
- The crystal and charcoal layers are marketing more than proven function
- One-year limited warranty only
Sun Home Saunas Sun Home Infrared Sauna Blanket
Bottom line. A good blanket let down for UK buyers by US shipping, import costs and slow returns.
Pros
- Award recognition and a 30-day money-back guarantee
- Strong EMF-shielding marketing and a UK-compatible 230V option
- Heats 35-75°C with a simple temperature-and-timer controller
Cons
- Priced in USD ($499) and shipped from the US, so import costs and slow returns apply
- No UK warehouse, making warranty claims and returns harder

MiHIGH Portable Infrared Sauna Blanket
Bottom line. The budget choice if you buy on sale and accept the reliability risk.
Pros
- Cheapest option here on sale (often around £140)
- UK-based ordering, support and returns
- Fits users up to 196cm with a 150kg weight capacity
Cons
- Poor independent reliability reputation (1.9/5 on Trustpilot, with reports of units failing after a few months)
- Only a one-year warranty, which matters more given the reliability reports
- List price of £315 is poor value; only worth buying on sale
How do infrared sauna blankets work?
A heating layer inside the blanket emits far infrared, which penetrates the skin and warms you from within. Because it heats your body rather than a whole room, a blanket draws far less power than a cabin sauna and needs no installation, plumbing or ventilation.
The trade-off is that your head stays outside, so it is a sweat-and-recovery tool rather than the full enveloping heat of a traditional sauna. Most people use one for 30 to 45 minutes, three or four times a week, on a bed or the floor.
What should you look for when buying?
Four specifications separate a good blanket from a gimmick:
- Published EMF data. Most brands claim "low EMF" but never publish a figure. A measured number you can check matters more than the phrase. The usual safety reference point is 2.0mG, so anything well below that is reassuring.
- Temperature ceiling. Look for at least 75°C. Below that you will struggle to break a proper sweat.
- Fit. Check both length and the maximum user height - taller users need a 180cm-plus blanket that is wide enough to zip fully.
- UK availability and warranty. A UK warehouse means no import duty and a returns address you can actually post to.

Are infrared sauna blankets safe?
Used sensibly, yes. The main considerations are heat and EMF. Keep sessions to 30 to 45 minutes, hydrate before and after, and avoid use if you are pregnant or have a heart condition without checking with a doctor first. On EMF, every blanket here markets itself as "low EMF", but only Bon Charge publishes a verified figure (0.16mG, well under the common 2.0mG reference point). Far infrared itself is non-ionising radiation, the same broad category as visible light and radio waves - see the overview of far infrared for the underlying physics.
