Dr Robert Becker and Dr john Zimmerman during the 1980s did extensive testing to try and determine what actually happened during a Reiki session.
Not only do the brain wave patterns of the practitioner and receiver be come synchronised in the alpha state, characteristic of deep relaxation and meditation, but they pulse in unison with the earth’s magnetic field. During these moments the biomagnetic field of the practitioner’s hands is at least 1000 times greater than normal.
It is suggested that linking of energy fields between practitioner and earth allows the practitioner to draw on the ‘infinite energy source’.

They further investigated the large pulsating magnetic field that is emitted from the hands of energy practitioners whilst they work. They discovered that the pulses are in the same frequencies as brain waves, and sweep up and down from 0.3 – 30Hz, focusing mostly in 7-8Hz alpha state. Independent medical research has shown this range of frequencies will stimulate healing in the body with specific frequencies being suitable for different tissues. For example 2Hz encourages nerve regeneration, 7Hz bone growth, 10Hz ligament mending and 15Hz capillary formation. Physiotherapy equipment based on these principles has been designed to aid soft tissue regeneration and ultra sound technology is commonly used to clear blocked arteries and disintegrate kidney stones.

‘Brain waves’ are not confined to the brain, but travel throughout the body via the perineural system, the sheaths of connective tissue surrounding the nerves. During treatment, these waves begin as relatively weak pulses in the thalamus of the practitioner’s brain and gather cumulative strength as they flow to the peripheral nerves of the body, including the hands. The same effect is mirrored in the person receiving the treatment.
