THE SCIENCE
How the Murmr cap works
Cold, darkness and gentle pressure are three things people with migraines have reached for forever. Murmr puts all three in one hands-free cap.
A 2022 review in the Journal of Clinical Nursing pooled studies of cold therapy for migraine, including cold gel caps, and found cold reduced pain in the short term, within about 30 minutes. Read the study
- Chill the cap until it is cold.
- Pull it on at the first sign of a migraine.
- Slide it down over your eyes, lie back and rest.
Murmr is a comfort product, not a medical device or treatment. Talk to your doctor about your migraines.
Not all migraine caps are the same
Why Murmr Beats the Rest
Most caps go in the freezer and stay there. Murmr was designed to come with you — to work, to bed, to the car — so comfort is there the moment you need it.

Made for Real Life
Removable Headgear
Pop it off to re-chill, warm, or wash — no wrestling a whole cap into the freezer.
3–6 Hours of Cold On The Go
Keep a second cap chilling in the insulated bag and swap when the first warms up — relief at work, in the car, or by the bed.
Warm in 30 Seconds
Need warmth instead? 30 seconds in the microwave and it's ready for tight neck, shoulders, and scalp.
Two ways to find relief
Cold When It Throbs. Warm When It's Tight.
Every head is different — and so is every headache. Murmr gives you both options in one cap.
❄️ Go Cold
Best when a migraine is building or pounding
- Cooling helps numb throbbing pain fast
- Gentle, even pressure around your whole head
- Research shows cold can lower pain within 30 minutes
- A drug-free option you can use alongside your usual plan
🔥 Go Warm
Best for tension in the neck, shoulders, and scalp
- Warmth boosts blood flow to tight, tense muscles
- Helps loosen the neck and shoulder tension that often comes with headaches
- Studied for easing tension-type headaches
- A cozy way to unwind after an attack passes
Not sure which to use? Many people start cold for throbbing pain, then switch to warm once the tension sets in.
Backed by research
What the Studies Say
Hot and cold therapy aren't just old-school remedies. Here's what researchers have found — cold works best for in-the-moment comfort, not as a long-term fix.
Cold caps & headbands eased pain within 30 minutes
A 2022 systematic review pooled 6 studies — including cold-gel caps and headbands — and found people using cold had significantly lower pain scores 30 minutes in than those who didn't.
Cold packs lowered migraine pain levels
In a 2024 study of 60 adults with migraine, applying a cold pack during episodes was linked to lower pain levels afterward.
Warmth helped relax tense muscles
In a small 2021 study, topical heat paired with massage reduced pain, headache episodes, and pain-reliever use in women with tension-type headaches.

For Her
My grandma is the strongest woman I know. She raised a family, kept everyone fed, and never once made us feel like a burden. She's the person I call when I don't know what to do. She also had migraines for as long as I can remember....
When a migraine hit
The whole house changed. Blinds shut. TV off. Everyone whispered. She’d lie in the dark with a bag of frozen peas on her forehead and a wet towel on her neck, sunglasses on even inside.
There was always one request: someone had to run to McDonald’s for an ice-cold Coke and the saltiest fries they had. Getting them for her was the one thing I could do to help, and I’d run as fast as I could.
What stuck with me most wasn’t the pain. It was how far away everything was. The ice was in the kitchen. Her pills were down the hall. And some days the woman who carried all of us couldn’t even lift her head off the pillow.
She missed birthdays and recitals. She stopped making plans, because she never knew when the next one would hit. Still, she never complained. The minute it passed, she was back in the kitchen asking if we’d eaten.
Why I made this
She deserved better than frozen peas and “just drink more water.”
So I built what I wish she’d had. Something that would let her rest in the dark without anyone having to run back and forth to the kitchen.
Something that was already there, right beside her, the moment the pain started. So she’d never have to wait alone for relief again.
It’s not a cure, and it doesn’t replace your doctor. It’s comfort that’s ready when you are.
Memaw, this one’s for you. And for everyone who’s ever had to wait out the pain in the dark.
