This ambient, deep sleep soundscape uses a 3 Hz binaural beat (111Hz & 108Hz) and is tuned to C528/A444. The lowest frequencies, delta waves are less than 4 Hz and occur in deep sleep.
As delta waves increase, our awareness of the physical world decreases and access to our unconscious mind becomes easier. It is often seen as a Gateway to Spirituality. Delta Waves are linked to DHEA Production.
When we are in the delta state, we release anti-aging hormones, including melatonin and DHEA, a hormone that slows the aging process, and improves well-being and cognitive function. Some people take supplements for this, but many conclude sleep is the best way to promote DHEA production.
Additionally, levels of the hormone cortisol dip during the deep sleep (delta) stage and increase over the night to promote alertness in morning. Delta subjective feeling states: deep, dreamless sleep, non-REM sleep, trance, unconscious, astral projection
