I’ve purchased my InfraMat two months ago and have been using it continuously ever since it arrived. It’s a splendid product and I enjoy using it for few hours at a time – I just can’t get enough! I usually let it heat first to about 55C while I’m doing other things around the house. I prefer lying on the mat when it’s already heated, as the cold stones can be unpleasant to the skin, especially in winter. Once it’s heated, I relax for a bit and then turn it up to 65C to increase the healing power. The temperature regulates itself, so even if the product seems to be going on and off it’s so to maintain the consistent temperature. I usually don’t go beyond 65C, otherwise I sweat, it’s too hot. I can only regret I have waited so long before buying this mat. If you hesitate, all I can say is – do it – it’s the best thing you can do for your aches and pains ; and it will pay for itself within few months. Now I’m considering saving on massage sessions, physiotherapy and acupuncture.
