RESEARCH
Hot topic Regular exercise could help reduce hot flushes in menopausal women and offer a natural alternative to HRT, according to UK researchers
Less frequent, less severe
Findings from an unpublished study were revealed at the annual conference of the European Society of Human Reproduction and Embryology in June. The university team based its research on 17 menopausal women with an average age of 52. Ten of the women undertook a gym-based exercise programme for four months, while seven formed a control group and carried on life as normal. The women in the active group exercised on a treadmill, static bike, rowing machine and cross-trainer and pushed themselves so they were out of breath but still able to talk. Workouts were built up over the four-month period, from three 30-minute sessions a week to five 45-minute sessions a week. At the end of the four months, the women in the exercise group experienced far fewer flushes – falling remarkably from 64 to 23 a week on average. The severity of the flushes had also dropped by two-thirds. In contrast, the women who remained sedentary reported very little difference.

A natural alternative
For an objective assessment, the researchers also placed women in a hot water suit to induce a hot flush and then recorded their physiological reactions. According to lead author Helen Jones, the women in the exercise group sweated less and had less blood flow to the skin. Jones believes exercise could be boosting the body’s ability to regulate temperature. She explains: “If it’s doing that when a flush is triggered, the sweating and skin blood flow responses are lowered because the control system is more efficient.” As the study was only a preliminary trial based on a small sample group, the researchers are now seeking further funding for a larger study. However, they do believe the early results show

promise, with exercise a possible natural treatment for menopausal symptoms. Up until a decade ago, most women were prescribed hormone replacement therapy (HRT) drugs to help combat hot flushes and other side-effects. But the number of women taking HRT has dramatically declined since the early 2000s when it was linked to strokes, blood clots and breast cancer. Jones concludes: “Because of the health scares in the past few years, not many women will be prescribed HRT. They’re basically living their lives with hot flushes, which isn’t a nice thing. We tried to use exercise as a nonpharmacological tool.” Exercise could also provide other advantages, she says: “Exercise training has additional positive benefits to postmenopausal women, importantly on cardiovascular and cerebrovascular disease risk, which increases following the menopause. Exercise also can improve quality of life and mental wellbeing.”

round three out of every four menopausal women have hot flushes, according to NHS data. They’re the most common symptom of the menopause and are described as a sudden, uncomfortable rush of heat that, with no warning, spreads throughout the body. They can include sweating, palpitations and a red flush (blushing), and while some women are relatively unaffected, others can experience up to 20 episodes a day. It’s believed that regular exercise can help improve temperature regulation, skin blood flow and sweat control. So with this in mind, researchers at Liverpool John Moores University are looking into the role physical activity might have in helping with menopause symptoms – and the preliminary results look promising.
