In
brain wave frequencies,
delta is the frequency range where the
deepest stage of sleep occurs.
Delta is approximately .5 to 4 cps (cycles per second). While
sleeping, a person will never reach 0 cps, or else they would be a vegetable and
brain dead… literally.
Dreaming can occur in the higher states of delta. Rejuvenation and
healing of the physical body happens while in the delta stage. Sometimes if you wake up and do not feel rested, your brain may have not reached delta, or may have spent a longer time than normal dreaming in
theta.
The brain waves are of the LARGEST
amplitude and s l o w e s t
frequency in
delta.
