Taking a 12-week yoga class and practicing at home was linked to less insomnia—but not to fewer or less bothersome hot flashes or night sweats. The link between yoga and better sleep was the only statistically significant finding in this MsFLASH (Menopause Strategies: Finding Lasting Answers for Symptoms and Health) Network randomized controlled trial.
Katherine Newton, PhD “Many women suffer from insomnia during menopause, and it’s good to know that yoga may help them,” said lead author Katherine Newton, PhD, a senior investigator at Group Health Research Institute. She e-published these findings in Menopause, ahead of print.
“Hormone therapy is the only Food and Drug Administration-approved treatment for hot flashes and night sweats,” Dr. Newton said, “and fewer women are opting for hormone therapy these days.” That’s why MsFLASH tried to see whether three more “natural” approaches—yoga, exercise, or fish oil—might help ease these menopause symptoms. The study assigned 249 healthy, previously sedentary women at multiple sites, including Group Health, to do yoga, a moderate aerobic exercise program, or neither—and to take an omega-3 fatty acid supplement or a placebo.
Exercise seemed linked to slightly improved sleep and less insomnia and depression, and yoga also was linked to better sleep quality and less depression—but these effects were not statistically significant. The omega-3 supplement was not linked to any improvement in hot flashes, night sweats, sleep, or mood.

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.
Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...
Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.
Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...
Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.
As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...
Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.
With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
