POWRNAPS uses Binaural beats to train the brain to relax and to awaken without the risk of grogginess. A scientific digital modulation process inserts precise pulses and beats that the brain hears. The difference in vibration between one ear and the other stimulates either deeper relaxation or alertness. Easy2Sleep and NAP26 uses vibrations to relax, and help you sleep peacefully without the grogginess from medications. The POWRNAPS Sleep System creates non-drug solutions, so you can learn to sleep better and better over time, without the risks.
