Energy Spent by the body

Body Composition Affects Energy Spent Standing Versus Sitting

Energy Spent; A person’s body composition could influence the difference between the amount of energy they spend while sitting versus standing, according to new research published in the open-access journal PLOS ONE. Conducted by Francisco J. Amaro-Gahete of the University of Granada, Spain, and colleagues; this work adds to mounting evidence that more energy is…

Circadian Rhythm

Circadian Rhythm Of ‘Night Owls’ By Non Pharmacological Interventions

Circadian Rhythm; A simple tweak to the sleeping patterns of ‘night owls’ people with extreme late sleeping and waking habits could lead to significant improvements in sleep/wake timings, improve performance in the mornings, better eating habits and a decrease in depression and stress. New international research by the Universities of Birmingham and Surrey in the…

Frequent screen users are much more likely to report falling asleep later, sleeping less, and waking during the night. Such difficulties are linked not only to poorer academic…

Understanding Of Cells

Innovative Mechanobiology Research Expands Understanding Of Cells

Researchers have developed a new technology that allows them to probe cell changes without disturbing the cell’s physiology — a major advancement that helps scientists look more closely at cell changes to solve human health problems, according to a new paper in Cell Reports. This technology, known as deformation microscopy, allows scientists to more accurately assess…

Menopause

Changes In Female Heart After Menopause

The female heart changes after menopause, but a new University of Guelph study is the first to reveal changes; that are happening during perimenopause the stage before menopause sets in. These small, underappreciated changes have potential implications for protecting women’s hearts by introducing the use of hormone replacement therapy earlier. “We found the window of…

Sleep/Wake Cycle

Seasonal Clock Changing Synchronizes Human Sleep/Wake Cycle

Scientific Reports released this month a paper by prof. José María Martín-Olalla (Universidad de Sevilla) analyzing seasonal similarities between the sleep/wake cycle in subtropical, pre-industrial and extratropical industrial societies. The results show that in winter, the sleep/wake cycle is dominated by sunrise. Wake-up times tend to occur during the winter twilight regulated by the circadian photorecpetive mechanism.…

Sleep Quality

Breakthrough Devices Can Improve Sleep Quality In Teenagers

Recent studies have indicated that exposure to too much evening light; particularly the blue light emitted from screens on smartphones, tablets and computers can affect the brain’s clock; and the production of the sleep hormone melatonin, resulting in disrupted sleep time and quality. Sleep in teenagers can be improved by just one week of limiting…
