Researchers found that 7 weeks of acupuncture treatment reduced the severity of nighttime hot flashes by 28% among menopausal women compared with a 6% decrease among women who had a sham acupuncture treatment.
The effects of acupuncture vs. a sham acupuncture treatment on the severity and frequency of nighttime hot flashes were compared. Taking part in the study were twenty-nine menopausal women experiencing at least seven moderate to severe hot flashes per day.
All of the women underwent nine treatments from trained acupuncturists in sessions over seven weeks. Twelve of the women received real acupuncture using points selected to target hot flashes and sleepiness. The rest of the women received a sham acupuncture treatment using non-penetrating needles at random acupuncture channel points.
Throughout the study, the women reported the number and severity of their hot flashes. The results showed that nighttime hot flash severity decreased significantly (twenty-eight percent) among the women who received acupuncture vs. a six percent drop among the women who got the sham treatment. However, they did not see a similar finding in the frequency of nighttime hot flashes between the two groups.
