The purpose of this research study was to investigate if Reiki could reduce episodes of insomnia and improve sleep patterns. Due to the fact that there is a paucity of research on Reiki’s effectiveness as an insomnia treatment method, a research study consisting of 15 volunteer subjects (10 females and 5 males at least 21 years old) who suffered from having difficulty falling asleep, difficulty staying asleep, and/or poor quality of sleep. The subjects learned and practiced Reiki techniques for self-healing. To measure the subjects’ experiences and responses to Reiki, each subject completed a pre-Reiki and post-Reiki "Beliefs and Attitudes about Sleep" questionnaire, a "Sleep Hygiene Analysis" questionnaire, and a "Stress and Anxiety" questionnaire. In addition, the subjects underwent pre and post Reiki interviews and vital signs assessments.
The results of this study indicate that Reiki is a beneficial therapy regimen for sleep disturbance because it decreases episodes of insomnia and improves sleep patterns. Reiki also promotes physical/mental calmness due to a healthy, stable parasympathetic nervous system, and Reiki is an alternative technique to decrease episodes insomnia without the use of pharmaceuticals.
