What is it?

The Fireactiv thermal support range combines the principles of a support aid and heat patches, to provide drug-free relief for muscle and joint aches and pains. No batteries, wires or microwaving is required; the special bio-ceramic heat reflective particles begin working automatically when worn against the skin, amplifying and radiating heat back into the body. Includes supports for a areas, including knees, lower back, shoulders, wrists and elbows.

What's it like?

I'm a big fan of heat products. Not only are they soothing but they increase blood-flow to an area, which also helps reduce pain and improve mobility. But disposable adhesive heat patches can be expensive; reusable ones offer more value.

The Fireactiv products can be used for joint support without the heat patches if you wish, and come in a choice of sizes with adjustable Velcro panels. Each one comes with both white heat patches, for a milder heat and the more intense and fast-acting red patches. I try the lower back support. The white patches take a while to feel warm and the effect is subtle, but after a few weeks of use, I do notice some relief and a reduction in stiffness.

I swap to the red patches for a more intense flare-up, and find them equally as effective as adhesive patches I've tried - but I can reuse these and the design means my posture's being supported too.
