Scientific Studies on Reiki and Surgery
Scientific studies show that Reiki is an effective complementary treatment to traditional pre-habilitation and rehabilitation surgery treatments and is effective in reducing pain, discomfort and anxiety levels. Because your nervous system deeply relaxes during a Reiki treatment your body surrenders to a state of deep rest allowing it to release stress and anxiety and naturally support the healing process.
