Specially processed with high-purity germanium and natural minerals! During sleep, germanium activates bioelectric currents, and far-infrared rays provide a warming effect. Memory foam pillow cover Applicable pillow size: Width 49-51cm Depth 29-31cm Height 9-11cm, 4-6cm ● A very small bioelectric current constantly flows through the human body, and muscles function due to their activity. It is said that when the balance of this bioelectric current is disrupted, it can lead to factors that induce stiff shoulders and lower back pain. Germanium, due to its electronic properties, is said to regulate the current balance within the body's cells, improve blood circulation, and relax joints and muscles. ● This product is specially processed with high-purity germanium and natural minerals and is evenly applied to the surface fabric of the pillow cover. During sleep, the germanium power and far-infrared rays from the shoulders to the head are expected to promote the activation of bioelectric currents flowing through the body.
