With each phase our sleep gets deeper, our body becomes more relaxed, and our brain wave patterns slow down. We experience our deepest sleep phase when our brain enters the delta wave state. Delta sleep is the phase in which the body regenerates and rebalances itself for the new day. Getting enough sleep is therefore essential for a healthy, productive life. This program has been proven to increase delta wave activity in your brain. The program has already helped many people to find regular, restful, and revitalizing sleep. Listen to one of the soundscapes whenever you want to go to sleep. NEOWAVES is a pioneer in the field of audio-acoustic research.
