Clinical study of heat therapy · 2001
7 in 10 women using heat got complete relief from their period pain.

Stop the cramp where it starts

Every period, pain chemicals make your uterus squeeze. On bad days it clamps down so hard it chokes off its own blood flow, and that starved muscle is the stabbing cramp in your belly, back and thighs.

The Period Therapy Brief works by:

  • Warming the clamped muscle with 3-level heat so it lets go
  • Loosening the bracing muscles with 4 massage motors on your belly and lower back

Result: in a study of 75 women, one 10-minute session of heat + vibration massage cut cramp pain by over a third.

Clinical study: heat worked as well as ibuprofen for period pain

Get complete relief without a pill

Heat relaxes the clamped muscle and opens the blood flow back up. In a clinical study of heat on the lower belly, 7 in 10 women using heat got complete relief. Heat therapy is now backed by 57 trials with over 5,000 women.

  • 3 heat levels: start low, turn it up
  • No pill, no side effects to wait out
Lying on her stomach reading, the brief's back panel glowing red over her lower back

Ease the ache that spreads into your lower back

For 3 in 4 women with period pain, it reaches the lower back too. The back panel puts heat, 2 massage motors and red light right on it, so your belly and back warm up together. In a 2020 trial, 20 minutes of heat on the belly and lower back cut period pain from 6.3 to 3.5 out of 10 within the hour.

Unclench the cramp and the muscles around it

When a cramp hits, the muscles around your belly and pelvis brace and squeeze even harder. 2 massage motors work your belly and 2 work your lower back while the heat keeps them warm. You don't rub, press or hold a thing.

  • 4 motors: 2 belly, 2 lower back, 3 levels
  • Massages your tummy and back, as the UK's NHS advises

Wrap your belly and lower back in a deep red glow

The brief holds 162 deep-red LEDs at 660 nm, the same deep red used in red light therapy panels. They run from your lower belly, between your legs, to your lower back, so one brief gives you heat, massage and red light.

  • 162 LEDs, 660 nm deep red
  • Glows while the heat and massage work

Fight back on endo flare days

With endo, tissue like your womb lining grows outside the womb and inflames everything around it, and your pelvic muscles brace hard around the pain. Heat and massage go after that bracing.

In a 2025 survey, 9 in 10 women with endo who manage their own pain use heat, and rate it one of the most effective things they do.

  • Heat rated 7.1 out of 10 for endo pain
  • For the flare days your treatment doesn't cover

Take back the days you can barely move

Day 1 cramps, endo flare days, the ache that got worse in your 40s: put it on the moment a cramp starts and lie back while the heat and massage work.

Keep living on day 1

A hot water bottle goes cold in 20 minutes and a heating pad keeps you on a cord by the wall socket, so the cramp clamps right back down. The brief runs on its own power bank in the front pocket and closes with velcro at your hips, so you can answer emails, make dinner or put the kids to bed while the heat and massage keep working.

  • Power bank in the front pocket
  • 3 timer settings, switches itself off
Painkillers on a nightstand at 3 AM

Skip pills that fail nearly 1 in 5 women

Painkillers only block the pain chemicals for a few hours before you're counting down to the next dose, and nearly 1 in 5 women get no relief from them at all. Across 8 clinical trials, heat came with about 70% lower risk of side effects than painkillers.

  • Nothing to swallow on an empty stomach
  • Nothing to restock every cycle

Do nothing and lose 9 days a year

That's what period pain costs women in lost work and cancelled plans, every year. If you're 25, you have about 300 more periods ahead of you, and every day 1 spent curled up on the bathroom floor is a day you don't get back. It is not "just a bad period", and you don't have to keep paying for it.

Up to 9 in 10women get period pain
190 millionwomen live with endometriosis
9 daysof productivity lost a year
Nearly 1 in 5get no relief from painkillers

Women with endometriosis, in their own words:

"It feels like a strangling wire is closing inside me."
"Carrying a hot water bottle makes me look crazy."
"I just want to function like a normal human being."
The brief next to a year of used heat patches and painkillers

Stop spending $100+ a year on heat patches

Disposable heat patches cost about $3 each and go in the trash after one use, so three a cycle runs over $100 a year before you buy a single painkiller.

The Period Therapy Brief is one payment of $89, and you put it on every cycle.

Questions? Answered.

How fast does it work?
You feel it working within minutes. The massage starts the second you switch it on and the heat builds over the first few minutes. In a study of 75 women, 10 minutes of heat + massage cut cramp pain by over a third, and in a clinical study of heat, 7 in 10 women got complete relief. Start on level 1 and turn it up.
Isn't this just a heating pad?
No. A heating pad warms one spot, slips off and keeps you plugged into the wall. The Period Therapy Brief heats your belly and your lower back at the same time, adds 4 massage motors and 162 deep-red LEDs, runs on its own USB power bank and switches itself off on a timer.
Does it help with endometriosis pain?
It's made for endo flare days. On a flare, your pelvic muscles brace hard around the inflamed tissue, and the heat and massage go straight at that bracing. 9 in 10 women with endo who manage their own pain use heat. Keep any treatment your doctor gives you; this is for the pain days it doesn't cover.
Do I wear it over or under my underwear?
Over. It goes on over your underwear or leggings, so your pad or period underwear stays right where it is during your period. Pull sweatpants over it and get comfortable.
How is it powered?
By USB. Every brief comes with a power bank that sits in the front pocket and plugs into the panel with a short USB cable. Charge the power bank by USB between uses, or run the brief from a USB wall adapter if you prefer.
Does it warm my lower back too?
Yes, it warms your belly and your lower back at the same time. A front panel sits over your belly, a narrow strip runs between your legs and a back panel sits over your lower back. The heat and the 162 deep-red LEDs cover front and back, and 2 of the 4 massage motors sit at your back. 3 in 4 women with period pain feel it in the lower back too.
Will it fit me?
It's one size. A black velcro wing on each side closes around your hips, so you set how snug it sits. It weighs just 1.2 lb.
Does it switch itself off?
Yes. Pick one of the 3 timer settings and it switches itself off when the time is up. It sits over your underwear or leggings, not on bare skin, and you choose from 3 heat levels, so start on level 1. Skip the heat if you're pregnant, have numb or broken skin, or have an implanted medical device, unless your doctor says it's okay. The maker lists FCC, CE and RoHS certification.
What does the red light add?
162 deep-red LEDs at 660 nm, the same deep red used in red light therapy panels. They run from your lower belly, between your legs, to your lower back, so one brief gives you heat, massage and red light.
Can I use it with painkillers or the pill?
Yes. It works alongside them. In a clinical study, adding heat to a painkiller brought relief almost twice as fast as the painkiller alone.
What if it doesn't work for me?
You get every cent back. Wear it through 2 full periods. If it doesn't stop your bad-cramp days, email hey@odelise.com within 60 days.

    Day 1 finally didn't own me

    I've spent every day 1 curled on the bathroom floor since I was 15. Put this on the second the cramps started last cycle, laid down for 20 minutes, and got up and made dinner. I actually cried a little, not gonna lie. It's warm and it massages at the same time and it just lets go.

    Endo girlies, this is the one

    Stage 4 endo here. My heating pad goes cold in 20 minutes and I have to hold it in place. This wraps me and stays put, and the back panel is everything because my flares always go to my lower back. It's not a cure, nothing is, but flare days are survivable now instead of me calling out of work.

    Took me one cycle to figure out placement

    First cycle I wore it too low and thought it was overhyped. Second cycle I moved it up over my belly button and wow, huge difference. Took a star off because the instructions could be clearer about placement. Once you get it right though, the heat plus massage combo is genuinely better than the 4 Advil I used to take.

    My mom bought it, I was rude about it, I was wrong

    My mom ordered this for me after my third sick day in a semester. I was like "mom it's a fancy heating pad." It is not a heating pad. It's cordless so I can actually move around, it massages, and it shuts itself off so I don't roast myself asleep. Sorry mom. Ordering one for my sister.

    12-hour shifts, saved

    I'm a nurse and I can't exactly run to the break room with a hot water bottle strapped to me. Wore it under my scrub pants on day 1 last week and forgot I even had it on. Three cycles in and I haven't taken a single period sick day since it arrived.

    I didn't want to keep swallowing pills

    I was taking 800mg of ibuprofen like it was candy every month and my stomach started letting me know about it. This doesn't fix everything but my pill count on my last period went from 6 to 1. That alone was worth it for me.

    No cord is the whole point

    My old heating pad literally chained me to my desk at work. This one has the battery in the pocket so I wore it to a meeting, to pick up my kids, making dinner. The relief is good but the freedom is what I didn't know I needed.

    42 and my cramps got WORSE

    Everything online talks about teen cramps but nobody warns you they can get worse in your 40s. Mine went from annoying to "send me home" over two years. This is the first thing that made them manageable again without me begging my doctor for something stronger.

    Bought the 2-pack, one for my 15 year old

    My daughter was missing school every single month, the nurse's office knew her by name. She uses hers on day 1 and 2 and she's stayed in class the last two cycles. I keep mine at my desk. Worth every penny for both of us.

    Did the math on my heat patches

    I was spending like $30 a cycle on those stick-on heat patches, and they'd peel off by lunch anyway. This paid for itself in about 4 months and it actually stays where you put it. One and done.

    Wish the timer was longer

    The relief itself is great, no complaints there. My only gripe is the longest timer setting shuts off before I'm ready on my worst days and I have to restart it. Still use it every single cycle, just hope they add a longer timer someday.

    My husband is a believer now

    He used to make jokes about my "belly sauna" and then he watched me go from curled up crying on the couch to cooking dinner in the same hour. He doesn't joke anymore. He also handles the battery charging now, which he volunteered for, so.

    Slept through a flare night

    Endo flares at 2 AM used to mean a bath at 3 and no sleep after. Last flare I put this on in bed, level 2 heat, and I actually slept through the night. I don't think people without chronic pain understand how huge that sentence is.

    Teachers can't just leave the classroom

    Try explaining to 28 second graders that you need to lie down because your uterus is attacking you. You can't. So I wore this under my clothes during my period week and just quietly turned the massage up between lessons. Game changer for a job where you can't tap out.

    Give it a few minutes to heat up

    It's not instant, takes about 5 minutes to get properly warm, which felt long in the moment when I first put it on. But once it's there it's there. Four stars only because of the wait, the relief itself is a five.

    Took it on a work trip

    The vibration is relaxing, not loud

    The back panel deserves its own review

    Nobody talks about the back pain part of periods. Mine radiates into my lower back and that's actually the worst of it. The back panel hits it directly while the front handles the cramps. That dual thing is what sold me and it's what I'd tell my friends about.

    My 16 year old refuses painkillers, just white-knuckles it every month. I got this for her and she actually uses it, which shocked me, because she rejects everything I buy. She says the heat feels "like a weighted blanket but warm." Whatever that means, she's using it.

    The glow is subtle, the heat is not

    Honestly the red light part I can't speak to, you can see the glow through light fabric which is kind of cozy, but the real MVPs are the heat and the massage motors. Took one star off just because the red light felt like a bonus feature more than a main one. Would buy again for heat + massage alone.

    Twenty years of periods, I've done the pills, the hot water bottle, the heating pad, those sticky patches, the weird TENS unit my sister swore by. This is the first one that made me think "why did nobody make this sooner." It wraps the whole area instead of one sad square of heat.
