Exercise no help against hot flashes: study

Getting regular exercise doesn’t seem to reduce the amount or severity of hot flashes among women going through menopause, according to a new study.

Researchers found that women who exercised had a small drop in the number of hot flashes they experienced per day, but the drop was no greater than what was seen in a group of women who didn’t exercise.

The study’s senior author said the findings should not keep women from exercising, because those who worked out reported better sleep and less depression.

“If the sole reason that you start exercising is to reduce hot flashes, you may be disappointed, but there are other reasons people should be exercising,” Bette Caan, of

the Kaiser Permanente Division of Research in Oakland, California, said.

Previous studies that looked at whether exercise helps reduce hot flashes – when blood vessels near the skin enlarge and blood flow increases – have found mixed results.

“Many (of the studies) show no effect, some show a small protective effect but the ones that have been well done have showed really no effect,” Caan said.

“We did this study because we wanted to do a really good controlled trial,” she added.

For the new study, published in the journal Menopause, the researchers randomly assigned 248 women from three U.S. medical centers to one of two groups.

Women in one group exercised three times per week for 12 weeks on a treadmill, elliptical or stationary bicycle. Those in the second group stuck to their usual activity.

All of the women were going through or had already gone through menopause and had frequent hot flashes at the start of the study.

Participants used daily diaries to track the number and intensity of their hot flashes. They also answered questionnaires about sleep quality and depression.

Initially, women in both groups experienced an average of between seven and eight hot flashes per day. At the end of the 12 weeks, they saw that drop to between five and six, with no significant difference between the groups.

There was also no difference in changes in hot flash intensity between the two groups from the beginning to the end of the study period.
