Did you ever watch Flashdance, the 1983 film that tanked in reviews but went on to be one of the highest grossing films that year? Guess it says a lot about our culture. Still, I am not going to say that I didn’t find it entertaining, or that Michael Nouri wasn’t hot in his day. But I digress…
For some reason, the film’s title came to mind when I stumbled across study that examined whether or not aerobic activity could ameliorate hot flashes and night sweats, perhaps because a lot of us dance around the issue rather than address it until it gets intolerable. Or perhaps because it makes a catchy header. Or maybe because Jennifer Beals works up such a sweat during her stand-in’s routine.
Regardless, on the heels of last week’s three-parter on ‘Forties fitness’ and motivating women, I thought I’d share some interesting information regarding physical activity, namely aerobic exercise.
Exercise. I’ve been pushing it for years because for me, it’s my drug of choice. What else offers benefits that include endorphins, wellbeing, bone health, metabolic booster and weight maintenance? And who would have thought that just 5o minutes, four times weekly could have a significant effect on the main cause of menopause flooding, including irritability, clothing changes, sheet replacement and crummy sleep?
That’s what researchers are reporting in Menopause. They discovered that when they assigned menopausal women to 6 months of aerobic training, the women experienced dramatic changes in mood swing, night sweats and irritability. Briefly, the women were divided into two groups:
- 50 minutes unsupervised aerobic training that with walking or Nordic walking (walking with ski poles) at least twice a week added to walking, Nordic walking, jogging, cycling, swimming, skiing, instructed aerobics or step class twice a week, plus two health lectures or,
- Health lectures twice weekly
They researchers were able to track target heart rates (64% to 80% of maximal) because the women in the aerobic training group were monitored and then given feedback All the women also reported the frequency/severity of menopausal symptoms (frequency of night sweats, mood swings, irritability, depressive mood, headache, vaginal dryness and urinary symptoms).
Although declines in symptoms (except vaginal dryness) were seen in both groups (which accounts for what they call a placebo effect, common to all studies), reductions in the prevalence of night sweats, mood swings and irritability were significant only in women engaging in regular aerobic activity. What’s more, because the women recorded their symptoms via a mobile phone, the likelihood that recall issues might come into play were reduced.
So, what about other studies that haven’t shown any benefit from exercise? The researchers point out that in their study, all the women had fairly substantial rates of symptoms (e.g. up to 60% had night sweats, 25% depression/irritability and 30% headache) while in other studies, the numbers at the start of the trials haven’t been quite as robust.
The upshot is that f you don’t care to jump on the hormone train, it can’t hurt to give aerobic activity a whirl. Just be sure to speak to a certified trainer and your health practitioner before diving in.
