A research team from Australia and China performed a systematic review and meta-analysis to investigate the efficacy of acupuncture in improving objective sleep measures in primary insomnia1. The analysis involved 775 patients from eleven studies. They concluded that acupuncture was significantly associated with improvements in several objective sleep parameters (increases in total sleep time and sleep efficiency, and reductions in wake after sleep onset and number of awakening times) as well as subjective sleep quantity and quality in patients with primary insomnia.
