𝚫 Delta brainwaves (1-3 hertz)

Delta brainwaves are the slowest, highest amplitude brainwaves, and are what we experience when players are asleep (dreamless sleep) or in the deepest meditation.

Delta waves suspend external awareness and are the source of empathy. Healing and regeneration are stimulated in this state, and that is why deep restorative sleep, essential to the healing process (cortisol reduction/DHEA increase).

Suppression of delta waves leads to the inability of body rejuvenation, brain revitalization, and poor sleep.
