Built for the way cramps actually work.
Continuous therapeutic heat. Calibrated vibration. Two physiological angles attacking the cramp at once — without pills, without patches, without the heating pad that quits at hour two.
If you've ever spent Day One on the bathroom floor — this isn't a trend.
You've tried the heating pad that goes cold at hour two. The patches that itch and don't last past lunch. The painkillers that strain your stomach if you take them often enough to actually help.
You've probably tried the popular wearable too — the one whose company stopped responding to your emails when it broke after six weeks.
None of it worked all the way for one reason: period cramps aren't one problem. They're three, happening at once. Most products fight one. peryode addresses all three.
That's why nothing's worked all the way.
And why this finally does.
The DualWave Relief System.
Cramps need more than one fix. peryode delivers both at once — the muscle, the vessel, and the nerve gate, in a single 4mm wearable.
ThermoWave
Continuous therapeutic heat at 38–45°C via PTC ceramic. Reopens the constricted vessels that prostaglandins clamp shut, restoring oxygen flow to the uterine muscle. Self-regulating. No overheating, no cool-downs at hour two.
NeuroWave
Calibrated vibration engages the gate-control mechanism in the spinal cord — dampening the pain signal before it reaches the brain. Three intensity levels, two pulse patterns. For the days when heat alone isn't enough.
Heat reopens the vessels.
Vibration closes the gate.
Together. Continuously. For five hours straight.
Three ways to start. Pick yours.
Every kit ships in molded recycled paper pulp. No plastic, no air-filled wasted space, no marketing leaflets.

I built peryode because nothing on the shelf actually worked for me.
I tried the heating pad. The patches. More ibuprofen than I should have, for too many years. The popular wearable that stopped working after six weeks while the company stopped responding to my emails.
The science showed me what was happening. Period cramps aren't just muscle contractions. Prostaglandin F2-alpha forces uterine hypercontraction and constricts the vessels feeding oxygen to the muscle. Nothing I owned addressed both at once.
So I worked with engineers and clinical advisors to build the wearable that did. Continuous therapeutic heat. Calibrated vibration that closes the gate on the pain signal at the spinal cord. Two mechanisms. One belt. Built once, kept for years.
