A recent systematic review published by Sleep Medicine (1) explored the efficacy of acupuncture for treating insomnia. A total of eleven studies that included an overall number of 775 participants. The research was able to provide the following evidence:
- Acupuncture increases total sleep time.
- Acupuncture improved efficiency, decreased wake after sleep and reduced the number of awake times.
- The subjective quantity and quality of sleep was also reported by the participants within the studies.
The researchers also found that the effect of acupuncture on regulating sleep would require a course of treatments of up to 12 sessions to simulate the treatment outcome found from the eleven studies.
