NuCalm works in a series of steps. The first step to all-natural relaxation is blocking out light. Then, the NuCalm Biosignal Processing Disc delivers electromagnetic frequencies to the body that biochemically help your brain interrupt adrenaline and cortisol release, by mimicking what naturally occurs in your brain right before you fall sleep. Finally, the “music” – the neuroacoustic software delivers frequencies to your brain that guide you to Theta brain wave lengths, which is the restorative “healing” zone. Combining all three components ensures you will achieve deep relaxation and the therapeutic outcome of autonomic nervous system balance every time you use NuCalm.
