The science behind it
Why CalmBelt works
Heat and vibration work together to target cramp pain at the source — not mask it.
Heat therapy
Targeted warmth at the source of the pain improves blood circulation and relaxes uterine muscles — the same principle used in physiotherapy, delivered directly to your abdomen.
Vibration massage
Four distinct massage patterns work with heat to interrupt pain signals and reduce tension. M4 deep mode mimics the pressure relief of a manual massage on cramped muscles.
Wearable freedom
Unlike a hot water bottle, CalmBelt stays on your body while you move. Wear it under clothes at work, on your commute, or doing anything you'd normally do.
Temperature guide
Five levels.
One for every moment.
Start low and work up. The LED display shows exactly which level you're on.
Massage control
Four vibration modes.
Built for your body.
Soft rhythmic pulses for light daily use and sensitivity.
Rolling wave pattern that builds and releases tension naturally.
Alternating strong and rest pulses to interrupt pain signals fast.
Continuous strong vibration for maximum relief on your worst days.
