A new study indicates that yoga and aerobic exercise interventions did not significantly reduce objectively measured sleep disturbances among midlife women who were experiencing hot flashes.

Secondary analyses of a show that neither 12 weeks of yoga nor 12 weeks of aerobic exercise had a statistically significant effect on objective measures of sleep duration or sleep quality recorded by actigraphy. Although the women had no difficulty falling asleep, disturbed sleep was common at baseline and remained after each intervention, with women in all groups waking during the night for an average of more than 50 minutes.

According to the authors, previously published analyses of the same trial had found that the yoga and aerobic exercise interventions were associated with small but statistically significant improvements in subjective, self-reported sleep quality and insomnia severity.

"Our primary findings were that the two study interventions had no significant effects on objective sleep outcomes in midlife women with hot flashes. The main implication of this finding is that other behavior treatments with the potential for effectively improving sleep in this population should be examined," said lead author Diana Taibi Buchanan, associate professor of Bio-Behavioral Nursing and Health Informatics at the University of Washington in Seattle.

Study results are published in the Jan. 15 issue of the Journal of Clinical Sleep Medicine.

The authors analyzed data from the Menopause Strategies: Finding Lasting Answers for Symptoms and Health (MsFLASH) network. The study involved 186 late transition and postmenopausal women with hot flashes who were between 40 and 62 years of age. Study subjects had an average of 7.3 to 8 per day. Participants were randomized to 12 weeks of yoga, supervised , or usual activity.

Sleep measures were evaluated using wrist actigraphy, and bedtimes and rise times were determined primarily from the participants' sleep diaries. Mean at baseline and after each intervention was less than the 7 or more hours of nightly that is recommended by the American Academy of Sleep Medicine for optimal health in adults.

According to the authors, future research should explore other approaches for improving in midlife women, such as cognitive behavioral therapy for insomnia.
