Study links relaxation method to reduced hot flashes

Although studies of the effects of relaxation techniques on menopause symptoms have yielded mixed results so far, a new report from Sweden comes down in favor of the approach as an alternative to hormone therapy.

Postmenopausal women trained to relax before and during the onset of hot flashes cut the frequency of those events in half during the three-month trial, researchers say. Women in a comparison group that got no treatments experienced little change in their symptoms.

"The results tell you that, yes, this seems to work," said Kim Innes of West Virginia University, who has studied mind-body therapies for menopause symptoms but was not involved in the new study. "This was a moderate-sized trial that yielded promising - although not definitive - findings regarding the efficacy of applied relaxation," she told Reuters Health.

In a review of more than a dozen previous clinical trials involving mediation, yoga and Tai Chi therapies, Innes concluded that these techniques may hold promise for relieving menopause symptoms, but it's too soon to tell.

In the years just before and after menopause, fluctuating hormone levels can generate a wide variety of symptoms, among the most bothersome are sudden flushing, night sweats and insomnia.

Hormone replacement therapy is thought to help by stabilizing the fluctuations, but not all women can take hormones because of other health conditions or risk factors, and many don't want to because of possible risks from the hormones themselves.

"A lot of women in Sweden do not want to or cannot use hormone therapy due to side effects," said lead author of the new study Lotta Lindh-Åstrand of Linköping University.

So Lindh-Åstrand's team set out to test the effects on menopausal hot flashes and quality of life of a method called applied relaxation that was developed in Sweden in the 1980s, based on type of psychotherapy called cognitive behavioral therapy.

The researchers recruited 60 healthy Swedish women and randomly assigned a little more than half to practice applied relaxation and the rest to a comparison group that received no treatment. The women, mostly in their fifties, had all stopped menstruating a year or more earlier but still experienced hot flashes and night sweats.

The 33 women in the therapy group learned how to focus on breathing and releasing muscle tension before and during hot flashes.

For the first week, the women observed and recorded what they felt before and during a hot flash or other menopausal symptom. Next, the women were encouraged to spend 15 minutes twice a day tensing and relaxing muscles from head to toe. Gradually, women learned how to decrease the time needed to relax by focusing on controlled breathing and not tensing the muscles. Toward the end of the study, the women were instructed to practice relaxation 20 times a day in 30-second sessions. The final "homework" exercise required the women to use these breathing and relaxation skills to quickly relax during a hot flash situation.
