Caffeine at Night May Disrupt the Body's Internal Clock

Posted 16 Sep 2015 by

WEDNESDAY, Sept. 16, 2015 – A small and preliminary study suggests that caffeine does more than serve as an eye-opener: When consumed a few hours before bed, the most widely consumed psychoactive drug in the world seems to disrupt the body's internal clock. And this could cause jet lag-style sluggishness during daylight hours, the study authors suggest. The research doesn't say anything about how coffee consumption in the morning or throughout the day may affect the body's internal clock. And the findings need to be confirmed. Still, it seems likely that coffee at night "isn't just keeping you awake," said study co-author and sleep researcher Kenneth Wright Jr., a professor with the Department of Integrative Physiology at the University of Colorado at Boulder. "It's also pushing your [internal] clock later so you want to go to sleep later." At issue: The body's circadian clock, which ... Read more

Gut Microbes Tied to Jet Lag, Shift-Work Weight Gain

Posted 16 Oct 2014 by

THURSDAY, Oct. 16, 2014 – Disruptions in the human circadian clock can throw off microbes in the gut, potentially boosting the risk of obesity, a new study suggests. The results may help explain why shift workers and people who get jet lag by traveling frequently often pack on extra pounds. "These surprising findings may enable us to devise preventive treatments for these people to lower their risk for these complications," senior study author Eran Elinav, of the Weizmann Institute of Science in Israel, said in a news release from the journal Cell. In the new research, Elinav and colleagues analyzed the microbes in the feces of humans and mice, and discovered that gut microbes follow a rhythmic pattern throughout the day. The cycle depends on eating habits and the circadian cycle of the human or mouse. The microbes were disrupted when the mice were exposed to an abnormal eating ... Read more

Health Tip: Minimize Jet Lag

Posted 17 Sep 2014 by

-- It's difficult to eliminate jet lag altogether, but there are things you can do to minimize symptoms of poor sleep, fatigue and difficulty concentrating. The American Academy of Family Physicians suggests how to help ease jet lag: Before you leave, get plenty of sleep. Once you arrive in the new time zone, adhere to local bedtimes and wake times. Eat well-balanced, healthy meals and follow the regular meal schedule of the new time zone. Avoid drinking too much alcohol, and don't overeat. Exercise as much as possible. Use sleep medications sparingly. Read more

New Animal Study Might Explain Jet Lag Differences

Posted 21 Oct 2011 by

FRIDAY, Oct. 21 – The way the human circadian clock sets itself may explain why jet lag tends to affect people more severely when they're flying west to east compared to the other direction, a new animal study indicates. The circadian clock, which regulates many body processes, has to make regular adjustments to stay synchronized with the light-dark cycle of where a person is and does this by delaying or advancing its time in response to light. Typically, these adjustments occur without notice. However, the process is disrupted by sudden major changes in the light-dark cycle, such as when a person takes a long flight. Previous research found that delaying and advancing the circadian clock occur in different pathways in an area of the brain called the suprachiasmatic nucleus. This new study found that the molecular mechanisms in these pathways are significantly different. "We have known ... Read more

Green Light Exposure Can Reset Body Clock

Posted 12 May 2010 by

WEDNESDAY, May 12 – Exposure to green light can reset the body's internal clock and alter sleep-related hormonal responses, new research suggests. The finding, reported in the May 12 issue of Science Translational Medicine, stems from research conducted by a team of scientists at Brigham and Women's Hospital in Boston, and builds on prior research about how the eye handles light exposure in ways that are unrelated to vision. So-called "non-visual responses" had previously been linked to blue light exposure, the study authors noted. In this regard, the eye's photoreceptor system located in the eye's ganglion cell layer, and distinct from the part of the eye responsible for processing sight, had been identified as a center for special cells that detect and absorb blue light, thereby triggering a shift in the viewer's internal circadian body clock. Blue light exposure had also previously ... Read more
