Acupuncture is associated with a significant reduction in sleep disturbances in menopausal women, conclude the authors of a systematic review from Taiwan. Meta-analysis of data from 31 randomised trials involving a total of 2,433 participants found that acupuncture was associated with a significant reduction in the likelihood of sleep disturbances, along with a significant increase in the secretion of serum oestradiol and a reduction in the secretion of follicle-stimulating hormone and luteinising hormone. Further analyses showed that studies in which Sanyinjiao SP-6 was used were associated with a larger increase in serum oestradiol level, compared with those that used other points. Larger increases in oestradiol levels due to acupuncture were associated with lower odds of sleep disturbances.
