Sleep disturbance can negatively affect physical and psychological health. Hypnotherapy may be effective for improving sleep with fewer side effects than other treatments. The purpose of this systematic review is to comprehensively identify studies and evidence regarding hypnotherapy for sleep disturbances. Four databases were searched to identify studies examining the use of hypnotherapy for sleep in adult populations. The search yielded 416 articles, of which 44 were included. Qualitative data analysis revealed that 47.7 of the studies showed positive results regarding the impact of hypnotherapy for sleep, 22.7 showed mixed results, and 29.5 showed no impact. A subset of 11 studies that set sleep disturbance as an inclusion criterion and included suggestions for sleep were examined separately and had more favorable results, such that 54.5 showed positive results, 36.4 showed mixed results, and 9.1 showed no impact results. Hypnotherapy appears to be a promising treatment for sleep disturbance. Future studies should report effect sizes, adverse events, and hypnotizability and include sleep-specific suggestions, standardized measures, and descriptions of hypnotherapy intervention procedures.
