Comfort you can actually wear.

A warm belt, a patch in your pocket, an off-switch for the hard days.

Three drug-free ways to ease period pain. The one with the best evidence behind it is also the simplest: steady warmth, held at the temperature the trials actually used.

Studied and effective. This is where Relief stays. Burn risk

Period pain deserves better than a pill or a prayer.

NSAIDs are first-line for good reason, but they fail for about one in five people, and taking them every cycle is hard on your stomach (BMC Women's Health, 2012). What's left is a shelf of near-identical heating belts: a hot spot in the middle, a battery that dies in an hour, and no stated temperature. We build the drug-free options properly instead.

What the trials actually found

Three physical methods have been studied properly. Here they are in order of how strong that evidence is.

Heat

Continuous low-level heat at ~40°C significantly reduced period pain in the randomised trial that started this whole category, and a follow-up found the same gentle heat did better still, with less cramping. A 2025 meta-analysis found the same thing. The researchers' objection was never that heat fails; it was that a hot water bottle "may be annoying and may interfere with daily life." That's the part we set out to fix.

High-frequency TENS

Electrical pulses at 80–100Hz crowd out pain signals before they register. The Cochrane review found high-frequency TENS beats placebo with an odds ratio of 7.2. Low-frequency TENS, the cheaper setting a lot of devices quietly default to, did no better than placebo at all.

Proctor et al. Cochrane, 2002 / 2009

Massage & vibration

It feels good, and a relaxed abdomen is a real thing. Most modern belts include it for that reason. But the trial evidence for vibration on its own is thin, well short of what exists for heat or TENS. It helps. It won't do the work on its own.

Reviewed alongside heat & TENS literature

What we do differently

None of this needs new technology. It's the basics, done properly, and you can check every line of it on the product pages.

Relief

Full-panel heat, even across the whole lower belly
3–4+ hours of continuous heat per charge
Held steady at 40–48°C, the range studies used
High-frequency (80–100Hz) TENS, clearly stated
Safety notes and contraindications on the page

Typical cheap belt

"Only heats up a small circle," reviewers say
Hours of charging for an hour or two of warmth
Unlabelled or excessive heat, which risks a burn
Frequency not stated, often the low kind that doesn't work
Contraindications buried or missing entirely

Short pieces on what eases period pain, and what only claims to.

Why we stop at 48°C

Hotter feels like it should work better. The trials disagree, and past a point the only thing extra heat adds is a burn risk.

One thing we don't sell: a network meta-analysis of 29 trials found that gentle exercise, relaxation, yoga and stretching meaningfully reduce period pain within a few weeks. If you try one thing this cycle, try that. (BMC Sports Science & Medicine, 2024)
