I use my Single Size Brown Biomat and wake up several times each night with some kind of buzz feeling. I used 5-th level as the mat was only slightly warm. Is it correct?

FIR amethyst mats do not work like conventional heating pads.

The surface may feel only warm to the touch, but the actual heat output is much higher. This is because most of the energy is delivered as Far Infrared (FIR) radiation rather than direct surface heat (conduction), as with standard heating pads. Traditional pads may feel hotter on the surface but do not provide the same level of deep, radiated heat.

On lower settings, the mat should feel slightly warm; on medium, warm; and on higher settings, very warm. However, the actual heating effect is significantly stronger due to the deep, penetrating nature of FIR heat.

Our body’s temperature receptors do not perceive radiant heat in the same way as direct contact heat. For this reason, the mat should always be used at lower “perceived” temperature levels compared to standard electric heating devices.

Extra care is recommended, especially during long sessions or overnight use. If the temperature is set too high, it may cause a feeling of overstimulation or a “buzzing” sensation.
