BEMER devices improve the forward movement of small and very small blood vessels, leading to proper blood distribution in the network of the smallest blood vessels. BEMER is therefore an effective therapeutic option for many diseases and health problems. The device effectively helps blood to flow through the smallest blood vessels, thereby improving the delivery of oxygen and nutrients to cells and the removal of metabolic waste products. All other effects can come from the effect of improving microcirculation. Thus, among other things, it can help relieve chronic inflammatory pain, for example in the case of joint pain. It can support regeneration and healing after injury, improve immune function (because good microcirculation is the basis for optimal functioning of the defence system) and help alleviate sleep problems, as improved microcirculation can positively influence sleep cycles.
