Many people will go to work on less sleep than normal Monday because they will have trouble adjusting to Daylight Saving Time. http://medicalxpress.com/news/2013-03-daylight.html Health Fri, 08 Mar 2013 10:31:02 EST news281961055 (Medical Xpress)—Most of us love a good Sunday sleep-in. But for some people, getting out of bed each morning can be a constant battle that significantly disrupts their lives. http://medicalxpress.com/news/2013-03-late-sleepers-hours-day.html Health Mon, 04 Mar 2013 09:10:01 EST news281608594 (Medical Xpress)—UC Irvine-led studies have revealed the cellular mechanism by which circadian rhythms – also known as the body clock – modify energy metabolism and also have identified novel compounds that control this action. The findings point to potential treatments for disorders triggered by circadian rhythm dysfunction, ranging from insomnia and obesity to diabetes and cancer. http://medicalxpress.com/news/2013-01-circadian-rhythms-potential-treatment-disorders.html Cardiology Tue, 22 Jan 2013 15:12:20 EST news278089921 Anybody who has worked the overnight shift will testify that sometimes the time displayed on the clock is not the same as the one in your head. This disconnect is not merely perception; many physiological functions follow an internal chronological rhythm. 'Body-time' can profoundly affect overall health and even the response to therapies for cancer and other disorders. http://medicalxpress.com/news/2013-01-natural-rhythm-shifting-molecules-blood.html Medical research Fri, 18 Jan 2013 08:30:01 EST news277719167 (Medical Xpress)—Today saw the launch of Re-Timer, a wearable green light device invented by Flinders University sleep researchers to reset the body's internal clock. http://medicalxpress.com/news/2012-11-re-timer-ready-reset.html Psychology & Psychiatry Wed, 21 Nov 2012 08:27:10 EST news272708819 We're often told by the popular press and well-meaning family and friends that, for good health, we should fall asleep quickly and sleep solidly for about eight hours—otherwise we're at risk of physical and psychological ill health. http://medicalxpress.com/news/2012-08-monday-medical-myth-hours-eachnight.html Health Tue, 28 Aug 2012 08:51:56 EST news265362707 Shift work is associated with an increased risk of major vascular problems, such as heart attacks and strokes, concludes a study published on bmj.com today. http://medicalxpress.com/news/2012-07-shift-linked-heart.html Health Thu, 26 Jul 2012 18:30:01 EST news262544906 Social jetlag -- a syndrome related to the mismatch between the body's internal clock and the realities of our daily schedules -- does more than make us sleepy. It is also contributing to the growing tide of obesity, according to a large-scale epidemiological study reported online on May 10 in Current Biology, a Cell Press publication. http://medicalxpress.com/news/2012-05-social-jetlag-real-health-hazard.html Medical research Thu, 10 May 2012 12:00:04 EST news255869118 International travellers, shift workers and even people suffering from obesity-related conditions stand to benefit from a key discovery about the functioning of the body's internal clock. http://medicalxpress.com/news/2012-05-body-clock-genes-unravelled.html Genetics Thu, 03 May 2012 05:26:40 EST news255241577 By analyzing the hundreds of metabolic products present in the liver, researchers with the UC Irvine Center for Epigenetics & Metabolism have discovered that circadian rhythms – our own body clock – greatly control the production of such key building blocks as amino acids, carbohydrates and lipids. http://medicalxpress.com/news/2012-03-circadian-rhythms-profound-metabolic-output.html Medical research Mon, 19 Mar 2012 17:01:31 EST news251395271 It's been said that timing is everything, and that may be particularly true when it comes to the ability to fight off disease. New research published by Cell Press in the February issue of the journal Immunity shows that the success of host immune defense depends in part on an organism's "body clock." The study may lead to therapeutic strategies designed to optimize the immune response and to protect patients at the time when they are most vulnerable. http://medicalxpress.com/news/2012-02-body-clock-immune.html Immunology Thu, 16 Feb 2012 12:00:05 EST news248612911 A study published in Nature Genetics today has found new evidence for a link between the body clock hormone melatonin and type 2 diabetes. The study found that people who carry rare genetic mutations in the receptor for melatonin have a much higher risk of type 2 diabetes. http://medicalxpress.com/news/2012-01-genetic-links-body-clock-receptor.html Diabetes Sun, 29 Jan 2012 13:00:15 EST news247034442 Researchers at Brigham and Women's Hospital (BWH) have demonstrated that the circadian system, the body's internal clock, regulates human platelet function and causes a peak in platelet activation corresponding to the known morning peak in adverse cardiovascular events. These findings are published in PLoS ONE on September 8, 2011. http://medicalxpress.com/news/2011-09-body-clock-platelet-function.html Cardiology Fri, 09 Sep 2011 10:03:23 EST news234781387 Sleep apnoea patients who are successfully treated have lower blood fat levels and a reduced risk of heart attack than people who are left untreated, University of Sydney researchers have found. http://medicalxpress.com/news/2011-08-heart.html Health Wed, 03 Aug 2011 14:00:12 EST news231598778 People who have a heart attack are likely to be more seriously affected if the attack happens in the morning, reveals research published ahead of print in Heart journal. http://medicalxpress.com/news/2011-04-heart-day.html Cardiology Thu, 28 Apr 2011 04:08:46 EST news223182488 The internally-driven daily cycle of blood pressure changes doesn't appear to be linked to the known increase in morning heart attacks, according to a study in Circulation Research: Journal of the American Heart Association. http://medicalxpress.com/news/2011-04-blood-pressure-internally-driven-daily.html Cardiology Thu, 07 Apr 2011 16:17:04 EST news221411815
