Relief backed by research.
Heat therapy and graduated compression are among the most well-studied non-pharmaceutical approaches to period discomfort. Here is why they work.
Heat helps relax the muscles causing the pain.
Period cramps are caused by uterine contractions, your uterus is squeezing to shed its lining. Those contractions cut off blood flow, which creates that familiar aching pain.
Applied warmth does two things: it helps relax the contracting muscles directly, and it supports circulation. Heat therapy is one of the most studied non-pharmaceutical approaches to period discomfort, with no gut irritation, drowsiness, or long-term side effects.
Massage that actually makes a difference.
Low-frequency vibration has been used in pain management for over forty years. It works through what is known as gate control theory: vibration signals reach the brain faster than pain signals, helping to interrupt the pain pathway.
It also helps release muscle tension. The HeatPulse Belt combines warmth and vibration in a single wearable device, something a hot water bottle, plug-in heating pad, or TENS machine cannot do alone.
The symptom no one talks about.
Most period conversations focus on cramps. But hormonal shifts mid-cycle also cause fluid retention, reduced circulation, and that distinct heavy-leg feeling. Many people experience swelling, aching calves, and leg fatigue without ever connecting it to their cycle.
Graduated compression at 20 to 30 mmHg is the standard pressure level used to support circulation, reduce fluid build-up, and ease muscular fatigue. The same level used for long-haul flights and recovery. FlowPulse brings that structured support into everyday cycle care, in a sock you can actually wear to work.
