What is Reiki?
Reiki comes from Japanese energy healing traditions. The word means Universal healing energy. 
Reiki is a natural and holistic complementary therapy that benefit us physically, mentally and emotionally.  Being holistic it works on the whole body and mind together, addressing the root cause.

How the Reiki healing works?
The Reiki practitioner, also known as a Reiki healer, is able to channel  universal energy through their body and hands onto the recipient's body or aura (biofield) to promote balance and healing.
The biofield is an electromagnetic field that permeates and surrounds every living being. In humans, this field extends 15 feet or more from the body, according to Ann L. Baldwin, PhD, a Reiki researcher and professor of physiology at the University of Arizona’s College of Medicine.
Research has shown that the biofield can be measured using techniques such as magnetic resonance imaging (MRI), electroencephalography (EEG), and heart rate variability (HRV).

For example, the heart produces an electrical field — measured through an electrocardiogram, or ECG — to regulate heartbeats. The brain also produces an electrical field, and all of the body's cells produce positive and negative electrical charges, which create magnetic fields.
According to this theory, the interaction between two human magnetic fields may explain the effects of touch therapies like Reiki. It is thought that the biofield is the energetic force that guides bodily functions, and that Reiki energy influences the biofield. 
is thought to cause dynamic changes in its vibrational qualities that alter physiological and psychological functions in living beings,” Dr. Baldwin says.
Quantum physics, the study of how the incredibly small particles that make up matter — electrons, neutrons, protons, and photons — behave, and attempts to explain the interactions of energy and physical matter. 

Quantum physicists have found that these tiny particles of energy can be in more than one place at one time (both a wave and particle at the same time, depending upon how it is examined, per the University of Pittsburgh), and that thought or intention may change how the particles work. 
Reiki therapy helps to harmonize the electromagnetic field and the polarity of body cells, that is creating balance for the body.
