Best Infrared Sauna Blankets in the UK

An infrared sauna blanket is the cheapest, smallest way to get an infrared sweat at home: you lie inside a padded, zip-up blanket that heats your body directly, with no room to build and no wiring to install. It will not replace a cabin, but for a flat, a spare bedroom or anyone short on space, it is the sensible entry point. This guide picks the best infrared sauna blankets you can actually buy in the UK, and explains the two specs, maximum temperature and EMF, that separate a good one from a gimmick.

If you are still deciding between formats, our infrared sauna blanket guide covers how they work, and far infrared vs full spectrum saunas explains the heat types.

What actually matters in a sauna blanket

Ignore the marketing and focus on four things:

• Maximum temperature. The useful range is roughly 65°C to 80°C. Below about 65°C you will struggle to raise a proper sweat. The best blankets reach the upper end of that band.
• EMF (electromagnetic field) output. Because the heating elements sit close to your body, low, independently verified EMF matters. Look for a brand that publishes third-party test figures rather than a vague “low EMF” claim.
• Materials and cleaning. A wipe-clean, non-toxic inner layer (many use a charcoal or medical-grade PU surface) is easier to keep hygienic. You will sweat a lot, so this matters.
• Controls and safety. A clear digital controller, an auto-off timer and a decent warranty are the marks of a serious product.

The best infrared sauna blankets in the UK

The three below are the models UK buyers should shortlist. Specifications change, so confirm the current version and figures on the manufacturer’s own page before buying, and check the warranty terms.

BON CHARGE Infrared Sauna Blanket

BON CHARGE is the current benchmark on the two specs that count. It reaches the top of the useful temperature range (around 80°C), which means a faster, deeper sweat, and its EMF has been independently verified through SGS testing at very low levels. That combination of higher heat and verified-low EMF is why it consistently comes out on top in side-by-side tests. If you want the strongest all-round performer, this is the one to beat.

HigherDOSE Infrared Sauna Blanket

HigherDOSE is the best-known name and a genuinely good product, particularly on trust: the brand publishes its own EMF testing and offers grounding/low-EMF construction. The current V4 tops out around 70°C, which is a touch lower than BON CHARGE, and the pricing reflects brand prestige as much as performance. Choose it if published EMF data and brand track record reassure you, and you do not mind paying for that.

MiHIGH Infrared Sauna Blanket

MiHIGH is the most recognisable UK-based brand, with domestic distribution, frequent promotional pricing and low-EMF positioning, so delivery and returns are straightforward. It is competently made and a common first blanket for UK buyers. The caveat is service: recent customer reviews flag inconsistent quality control and slow warranty responses, so buy from a channel with a clear returns policy and keep your proof of purchase.

A note on budget and unbranded blankets

Amazon and marketplace listings are full of cheap, unbranded infrared blankets. Some are fine; many quote a maximum temperature they never reach and make “low EMF” claims with no test data behind them. If you go budget, treat unverified EMF claims with caution and be ready to return anything that will not get hot enough. A blanket you never use because it barely warms up is not a saving.

Who a sauna blanket suits (and who should get a cabin)

A blanket is right for you if space or budget rules out a cabin, you want portability, or you mainly want the sweat and relaxation. It is not right if you want the social, upright, breathe-the-heat experience of a traditional or infrared cabin, or if you want to add cold exposure afterwards. For those, see our best infrared saunas UK round-up and the infrared saunas buyer’s guide.

Getting the most from it

Lay it on a firm surface, preheat for 10 to 15 minutes, wear light long-sleeved clothing or a towel layer to protect your skin from the elements, and keep sessions to 20 to 45 minutes. Hydrate before and after. Wipe the inside down after each use to keep it hygienic. On the wellness side, keep expectations realistic: regular sauna use is associated with relaxation and cardiovascular benefits in the research, but a blanket is a comfort and recovery tool, not a medical device. Our sauna health benefits page summarises what the evidence actually shows, and the peer-reviewed overview from PubMed Central on sauna bathing and health is a reliable starting point. If you have a heart condition or are pregnant, check with your GP first.

Frequently asked questions

What is the best infrared sauna blanket in the UK? On the specs that matter, the BON CHARGE blanket leads, with a high maximum temperature (around 80°C) and independently SGS-verified low EMF. HigherDOSE is the best-known alternative with published EMF data, and MiHIGH is the convenient UK-based option, though its customer service gets mixed reviews.

What temperature should an infrared sauna blanket reach? Aim for a maximum in the 65°C to 80°C range. Below about 65°C you will struggle to raise a proper sweat. The best blankets reach the upper end, which gives a faster, deeper session.

Are infrared sauna blankets safe in terms of EMF? Reputable blankets keep EMF low, but the elements sit close to your body, so it is worth choosing a brand that publishes independent EMF test results rather than an unverified “low EMF” claim. BON CHARGE and HigherDOSE both provide test data.

Is a sauna blanket as good as a real sauna? For raising a sweat and relaxing at low cost and in minimal space, yes. But a blanket cannot replicate the upright, breathe-the-heat experience of a cabin, the social aspect, or easy hot-and-cold contrast therapy. If those matter, choose an infrared or traditional cabin instead.

How long should you stay in an infrared sauna blanket? Most people use it for 20 to 45 minutes after a 10 to 15 minute preheat. Start shorter, hydrate well before and after, and stop if you feel unwell. Wipe the inside down after each session to keep it clean.

Do infrared sauna blankets help with weight loss? Any immediate weight change is water lost through sweating and returns as soon as you rehydrate. Sauna blankets are a recovery and relaxation tool, not a weight-loss device. Treat any claim of fat loss with scepticism.
