Yoga, exercise fail to improve sleep in women: Study

Yoga and aerobic exercise interventions may not significantly reduce sleep disturbances among midlife women experiencing hot flashes, according to a new study.

Researchers at University of Washington in the US said 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.

"Our primary findings revelaed that the two study interventions really had no significant effects on the objective sleep outcomes in middle life of the women along with hot flashes that they complain of ," said Diana Taibi Buchanan, associate professor at the University of Washington.
