Menopausal women could 'work out' their hot flashes

28.06.2012
Menopausal women who exercise may experience fewer hot flashes in the 24 hours following physical activity, according to health researchers.

In general, women who are relatively inactive or are overweight or obese tend to have a risk of increased symptoms of perceived hot flashes, noted Steriani Elavsky, assistant professor of kinesiology at Penn State.

Perceived hot flashes do not always correspond to actual hot flashes. Most previous research analyzed only self-reported hot flashes. This is the first study known to the researchers to look at objective versus subjective hot flashes.

Elavsky and colleagues studied 92 menopausal women for 15 days. The women recruited for this study were different from many earlier menopause studies, said Elavsky. In the past, women in menopause studies were experiencing severe symptoms and seeking help. They were probably not representative of the general population.

"Our sample included women with mild to moderate symptoms and they were recruited for a study of physical activity, not for a study of menopause," said Elavsky. "We recruited women residing in the community. We used recruitment sources that included a variety of outlets in the community frequented by women, like libraries, fairs, gyms, advertisements in local newspapers, etc."

The women were 40 to 59 years old, with an average of two children and were not on hormone therapy. During analysis the researchers separated the women into normal weight and overweight/obese categories and higher fit and lower fit categories. These categories were not necessarily mutually exclusive.

The participants wore accelerometers to monitor their physical activity and also wore monitors that measured skin conductance, which varies with the moisture level of the skin. Each participant recorded the individual hot flashes she had throughout the 15-day period on a personal digital assistant.

Through these two methods of recording hot flashes, the researchers found the frequency of objective and subjective hot flashes. Objective hot flashes occurred when the monitor recorded them; subjective hot flashes occurred when the woman reported them. When an objective and a subjective hot flash were recorded within five minutes of each other, it was considered a "true positive" hot flash, the researchers report in the current issue of Menopause.

"Some physiological explanations would suggest that performing physical activity could increase hot flashes because it acutely increases body core temperature," said Elavsky.

To the contrary, the researchers found that this premise was not true, as on average the women in the study experienced fewer hot flash symptoms after exercising. However, the women who were classified as overweight, having a lower level of fitness or were experiencing more frequent or more intense hot flashes, noticed the smallest reduction in symptoms.

It is not yet known if a woman could use diet and exercise to lose weight and become more fit and therefore experience fewer hot flashes, but it is a possibility worthy of future investigation, noted the researchers.

"For women with mild to moderate hot flashes, there is no reason to avoid physical activity for the fear of making symptoms worse," said Elavsky. "In fact, physical activity may be helpful, and is certainly the best way to maximize health as women age. Becoming and staying active on a regular basis as part of your lifestyle is the best way to ensure healthy aging and well being, regardless of whether you experience hot flashes or not."

Also working on this research were Joaquin U. Gonzales, assistant professor of exercise physiology, Texas Tech University; David N. Proctor and Nancy I. Williams, both professors of kinesiology and physiology, Penn State; and Victor W. Henderson, professor of health research and policy and neurology and neurological sciences, Stanford University.

The National Institute of Child Health and Human Development supported this research.

Im Focus: A step towards controlling spin-dependent petahertz electronics by material defects

The operational speed of semiconductors in various electronic and optoelectronic devices is limited to several gigahertz (a billion oscillations per second). This constrains the upper limit of the operational speed of computing. Now researchers from the Max Planck Institute for the Structure and Dynamics of Matter in Hamburg, Germany, and the Indian Institute of Technology in Bombay have explained how these processes can be sped up through the use of light waves and defected solid materials.

Light waves perform several hundred trillion oscillations per second. Hence, it is natural to envision employing light oscillations to drive the electronic...

Im Focus: Freiburg researcher investigate the origins of surface texture

Most natural and artificial surfaces are rough: metals and even glasses that appear smooth to the naked eye can look like jagged mountain ranges under the microscope. There is currently no uniform theory about the origin of this roughness despite it being observed on all scales, from the atomic to the tectonic. Scientists suspect that the rough surface is formed by irreversible plastic deformation that occurs in many processes of mechanical machining of components such as milling.

Prof. Dr. Lars Pastewka from the Simulation group at the Department of Microsystems Engineering at the University of Freiburg and his team have simulated such...

Im Focus: Making the internet more energy efficient through systemic optimization

Researchers at Chalmers University of Technology, Sweden, recently completed a 5-year research project looking at how to make fibre optic communications systems more energy efficient. Among their proposals are smart, error-correcting data chip circuits, which they refined to be 10 times less energy consumptive. The project has yielded several scientific articles, in publications including Nature Communications.

Streaming films and music, scrolling through social media, and using cloud-based storage services are everyday activities now.

Im Focus: New synthesis methods enhance 3D chemical space for drug discovery

After helping develop a new approach for organic synthesis -- carbon-hydrogen functionalization -- scientists at Emory University are now showing how this approach may apply to drug discovery. Nature Catalysis published their most recent work -- a streamlined process for making a three-dimensional scaffold of keen interest to the pharmaceutical industry.

"Our tools open up whole new chemical space for potential drug targets," says Huw Davies, Emory professor of organic chemistry and senior author of the paper.
