THE SCIENCE OF SOUND
BRAIN WAVE ACTIVATION
brain waves
during yoga nidra
THOUGHTS PER MINUTE
BETA: 13-40 HERTZ
Waking state
Rational mind use, externally directed attention
GAMMA: 40-100 HERTZ
Subset of Beta (can also appear in REM sleep)
Important for learning, memory and information processing synchs all areas of the brain
YN increases Gamma brainwave activity
At 50 hertz, stem cells are created
75 hertz, triggers genes that produce anti-inflammatory response
ALPHA: 8-12 HERTZ
(YOGA NIDRA PHASE 1)
(Dreamlike images intermingling with guidance, mind chatter but not participating)
Subconscious
A high alpha is between sleep and wakefulness
Increased secretion of serotonin
Immune system boosted
Bridge into sleep
Associated with meditation (seated meditation)
Increased receptivity; super learning
Low alpha, high delta is associated with dreaming
THETA : 4-7 HERTZ
(YOGA NIDRA PHASE 2)
(Gaps of awareness, words heard, not making sense, spiritual experiences)
Low alpha/high theta where REM or dream occurs
Most of the work of yoga Nidra
Superlearning, creativity, children and artists
Left and right brain synchronization
Emotional integration/brain changes
Strips the sticky plaque from neurons for Alzheimer’s
Clears toxins from the brain
Low Theta and Delta is deep sleep
DELTA : 0.5-3.9 HERTZ
(YOGA NIDRA PHASE 3)
(Transcelike, non-physical state, no body awareness, paradoxical stillness)
Deepest, most restorative
Human growth hormone is released
Growth and regeneration all organs and nerve cells (0.5-3 hertz)
(Excess) Cortisol removed
Quiet, in a coma
Increase muscle mass, bone density,
