Dr Maiysha Clairborne Reveals Top Mind, Body Spirit Tips to Aid Peaceful Slumber Atlanta, Georgia (PRWEB) July 17, 2013 How often do you get enough sleep? You might say that your lifestyle doesn’t permit you to get very much. For millions of Americans, it’s not a choice; researchers say that sleep disorders are becoming an increasingly common health issue in the US, with an estimated 70 million Americans suffering the consequences of not being able to get enough rest. The National...

Shift work, which encourages sleep deprivation and patterns of activity outside the circadian rhythm, has been associated with a greater risk of ill health and loss of well-being in some (but not all) studies. However, little is known about the effects of shift work on reproductive health and fertility. Now, a study reported today at the annual meeting of ESHRE, by Dr Linden Stocker from the University of Southampton, UK, indicates that working shift patterns is associated with an...

Risk not just confined to nurses, as previous research has indicated Shift work has been suggested as a risk factor for breast cancer, but there has been some doubt about the strength of the findings, largely because of issues around the assessment of exposure and the failure to capture the diversity of shift work patterns. Several previous studies have also been confined to nurses rather than the general population. In this study, the researchers assessed whether night shifts were...

Maximizing melatonin production in humans is possible by blocking blue light for a few hours before bedtime by wearing amber eyeglasses according to Richard L. Hansler PhD of Photonic Developments LLC. This may be of benefit in avoiding or treating liver cancer. University Heights, OH (PRWEB) June 27, 2013 A new paper from Thailand (1) shows that melatonin improves the outcome when liver cancer is induced in hamsters. A new study (2) from Spain found that melatonin blocked the processes...

Grocery Store Cabbage Is Alive And On A Circadian Rhythm

Michael Harper for redOrbit.com – Your Universe Online A new study from Rice University and the University of California at Davis (UC Davis) could have vegetarians questioning their motivations for avoiding meat. According to these researchers, vegetables are still very much alive even after they've been harvested, and are even beholden to the circadian rhythms of dark and light schedules. What's more, these vegetables might even be healthier for us at certain times of the day, say...

Gladstone-led study sheds light on molecular basis for metabolic health and disease Inside each of us is our own internal timing device. It drives everything from sleep cycles to metabolism, but the inner-workings of this so-called "circadian clock" are complex, and the molecular processes behind it have long eluded scientists. But now, researchers at the Gladstone Institutes have discovered how one important protein falls under direct instructions from the body's circadian clock....

Diverse Activity Patterns Of Birds During The Arctic Breeding Season
2013-06-19 11:17:58

Max-Planck-Gesellschaft Our internal circadian clock regulates daily life processes and is synchronized by external cues, the so-called Zeitgebers. The main cue is the light-dark cycle, whose strength is largely reduced in extreme habitats such as in the Arctic during the polar summer. Using a radiotelemetry system a team of researchers from the Max Planck Institute for Ornithology have now found, in four bird species in Alaska, different daily activity patterns ranging from strictly...

Urban Blackbirds Have Faster Circadian Rhythms Than Rural Relatives
2013-06-19 10:27:24

Brett Smith for redOrbit.com - Your Universe Online For years we have known about the differences between city slickers and country bumpkins, but a new study from the Max Planck Institute in Germany has shown that the different environments can have different effects on an organism´s natural biological rhythms. Along with ornithologists from the University of Maine and the University of Glasgow in Scotland, the Max Planck researchers studied the circadian rhythm of both urban and...

Pineal Gland
2013-04-30 10:31:18

The pineal gland, also called the epiphysis cerebri, is an endocrine organ located in the brain. Its primary function is to regulate the sleep cycle and influence sexual development. It is a reddish-gray glandular structure that forms the roof of the third ventricle in the brain, between the two lateral ventricles, tucked in a groove near the thalamic bodies. Its body is relatively the size of a grain of rice; it’s shaped like a pine cone and has an infindibular stalk projecting from it....
