Often, the practitioner will feel sensations of heat and tingling in the hands during a treatment. This is normal-simply the energy transferring itself. Once treatments are over, you should wash your hands in cold water, to break the connection with the recipient. Treatments often leave the practitioner and the recipient feeling a little dehydrated, therefore always have a glass or bottle of cold water for each of you. As well, at the end of the day, you should smudge the room used for treatments, to rid the area of any negative energies.
Cool showers are beneficial to the practitioner if many treatments have been given.
Reiki is a powerful, highly effective method of healing that is at once physical as well as spiritual. It is not a religion or a cult. Anyone attuned to the Reiki energy by a master can use it, and you needn't become a master to heal effectively. Reiki healing can be done at any time, anywhere, even over great distances. It does not necessarily need to be done only when there is an illness present, it can be done in health as well.
