What do amethyst and black tourmaline do in FlowPEMF?

FlowPEMF IR Mat Pro contains natural amethyst and black tourmaline, which are part of the mat's infrared heating system. When the minerals are heated, they help emit far infrared radiation (FIR) within 5–14 µm, together with the mat's other heating and infrared layers.

The purpose is to help provide even, comfortable infrared heat across the body, complementing the mat's PEMF function.
