Acupuncture is effective for insomnia relief. Research published by Zhejiang Chinese Medical University finds acupuncture more effective than a powerful sleep drug for improving sleep duration, quality, latency, efficiency, and daytime functioning. Acupuncture achieved a 92.9% total effective rate and the drug zopiclone achieved a 67.9% total effective rate. 
Zopiclone is a central nervous system depressant used for helping patients fall asleep and maintaining sleep throughout the night. The Zhejiang Chinese Medical University research indicates that acupuncture is more effective than zopiclone for improving these sleep parameters. Zopiclone is limited to short-term use because patients develop tolerance or dependence, risking the possibility of addiction. Although a nonbenzodiazepine hypnotic agent used as a sedative, zopiclone enhances GABA (gamma-aminobutyric acid) via benzodiazepine receptors. Consequently, withdrawal symptoms are similar to those of benzodiazepines. The research indicates that acupuncture is an effective alternative without the adverse effects associated with drug intake.
Acupuncture improved sleep latency for patients in the study. This is the time to transition from wakefulness to sleep. Acupuncture also improves sleep efficiency. This is the percentage of total time spent sleeping at night while in bed. In Traditional Chinese Medicine (TCM), these parameters are paramount to an accurate differential diagnosis. Imbalances preventing falling asleep and imbalances causing patients to wake have differing causes within TCM. As a result, acupuncture and herbal medicine modifications are based on how easily patients fall asleep, how often they wake, and what times of day they wake.
