Reiki is a Japanese form of energy healing that doesn't involve touch. It can be used alongside acupuncture to address various physical and emotional conditions such as insomnia, stress, anxiety, and pain. Reiki works by delivering energy to the body through gentle touch, promoting relaxation and reducing stress. The technique aims to improve the flow and balance of energy, supporting healing and overall well-being. Developed by Mikao Usui in the early 1900s and deriving the term from the Japanese words rei, meaning "universal," and ki, which refers to the vital life force energy that flows through all living things, Reiki is now widely used worldwide as a complementary treatment.
