The headband band neutralizes the impact of electromagnetic fields (EMF) and radiofrequency (RF) waves on the brain. It protects the brain from the oppressing impact of artificial EMF sources such as Wi-Fi devices, cell phones, computers, Bluetooth, microwave ovens, electrical wiring and cell towers. ROKKOO defends your brain from an exposure to natural EMF sources during an increased solar activity such as magnetic and geomagnetic storms, helps to reduce meteoropathy and geopatic stress symptoms.
