Reiki is a Japanese word that means spiritually guided life force energy. It is a form of biofield therapy, which is based on the principle that fields of energy and information surround living systems and that these fields can be influenced by a practitioner to stimulate healing responses. Most biofield therapies involve an energetic exchange between practitioner and client, which can be draining for the practitioner. Reiki is different in that the practitioner simply allows the Reiki energy to flow passively through their hands and into the client. Reiki helps to restore the client's energies to a state of balance on the physical, emotional, and spiritual levels, thereby enhancing the client's natural ability to heal.
Systematic reviews and meta-analyses of Reiki reveal that it has statistically significant improvements in many physical and psychological symptoms common to a wide range of diseases such as mood problems, anxiety, depression, fatigue, pain, and nausea.
The 2019 study measured the Physical and psychological health-related measures included pain, tiredness, drowsiness, nausea, appetite, shortness of breath, depression, and anxiety.
The results from this large-scale multisite effectiveness trial suggest that a single session of Reiki improves multiple variables related to physical and psychological health.
But putting all the research aside, you have to experience Reiki to feel the difference. Whilst a single session can help, if you have chronic illness, stress or anxiety then you will notice more balance and a shift in energy with multiple sessions in a shorter timeframe.
Reiki allows your body to come back to its natural state of energy and that is a personal experience for each individual. That is why each person has a unique Reiki experience and as you clear and expand your energy each session is also a unique experience.
