Sleep Music with Delta Wave Binaural Beats & Low 40 Hz Tones

The delta brainwave state is the lowest in the brainwaves chart. These are slow brainwaves, associated with sleep. The delta state is generally considered to operate between 1-4 Hertz, though recent research shows that these waves go as low as 0.5 Hz. Delta waves are associated with deep sleep because they are dominant in the late stages of the sleep cycle. The 4 stage of the sleep cycle has more than 50% delta wave activity and is when your body regeneration occurs. So, if you don't get enough delta sleep, then you won't feel fully refreshed when you wake up. If you ever wake up feeling grumpy and irritable, you probably didn't get enough delta sleep.
