Reiki in Contemporary Healthcare: Historical Development, Theoretical Foundations, Biofield Mechanisms, and...

Reiki, a recognized biofield therapy, channels universal life energy to promote healing and restore balance. This review explores Reiki's historical origins with Dr Mikao Usui, its global dissemination, and distinctions from related practices such as Qigong and Tai Chi. It outlines the structured training levels, including attunement processes that enhance practitioners' capacity to channel energy. Theoretical frameworks-particularly Martha Rogers' Science of Unitary Human Beings and the concept of quantum entanglement-are examined to elucidate Reiki's potential mechanisms. Current evidence suggests Reiki benefits stress reduction, pain management, and emotional well-being, with systematic reviews indicating improved quality of life in diverse populations. Despite promising findings, challenges in protocol standardization and research rigor persist. This review advocates for rigorous trials to validate efficacy and optimize clinical practice. As integrative therapies gain prominence, a comprehensive understanding of Reiki's foundations and clinical impact remains essential for advancing holistic patient care.
