Short Flashes of Light May Treat Jet Lag

Posted 2 days 11 hours ago by

TUESDAY, Feb. 9, 2016 – Researchers are working on a faster light-based therapy to prevent jet lag. Currently, light-based jet lag prevention involves exposure to bright lights for hours at a time during the day to help the body clock adjust to a new time zone in small steps before going on a trip, the researchers explained. But, exposure to short flashes of light – similar to camera flashes – while people are sleeping appears to be a fast and efficient way of preventing jet lag, the Stanford University researchers found. "This could be a new way of adjusting much more quickly to time changes than other methods in use today," study senior author Jamie Zeitzer, an assistant professor of psychiatry and behavioral sciences at Stanford in Palo Alto, Calif., said in a university news release. Conducting light therapy at night tricks the body clock into adjusting to a different wake/sleep ... Read more

Texting After Dark May Harm Teens' Sleep, Grades

Posted 6 days ago by

FRIDAY, Feb. 5, 2016 – Instant messaging can be a source of emotional support for teens and help them collaborate on school projects, but new research shows that texting after the lights go out takes a toll on students' sleep quality and academic performance. "We need to be aware that teenagers are using electronic devices excessively and have a unique physiology," study author Xue Ming, a professor of neuroscience and neurology at Rutgers New Jersey Medical School, said in a university news release. "They tend to go to sleep late and get up late. When we go against that natural rhythm, students become less efficient." During the study, researchers examined the link between instant messaging (such as texting) and academic and sleeping troubles among young people. "During the last few years I have noticed an increased use of smartphones by my patients with sleep problems," Ming said. "I ... Read more

Catch-Up Sleep May Reverse Type 2 Diabetes Risk Tied to Sleep Loss: Study

Posted 19 Jan 2016 by

MONDAY, Jan. 18, 2016 – Though prior research warns that sleep deprivation may increase the risk of type 2 diabetes, a new study suggests that "catch-up" sleep might reverse that risk – at least in the short-term. Short-changing sleep during the week only to sleep in for long periods on the weekend is a common pattern in the United States, according to the study authors. And, previous research has suggested that getting just four or five hours of sleep a night can boost type 2 diabetes risk by nearly 20 percent. But the new study hints that that risk might be reversed with just two days of extra sleep. "I have to say that this is a small, very short-term controlled study involving only healthy men," said study lead author Josiane Broussard, an assistant research professor with the Sleep and Chronobiology Laboratory at the University of Colorado in Boulder. "In real life, you'd be ... Read more

Health Tip: Sleep Well on Vacation

Posted 5 Jan 2016 by

-- While vacation is supposed to be a time to rest up, busy schedules and being away from home can interfere with sleep. The National Sleep Foundation recommends: Avoid making significant changes to your sleep schedule, such as staying up late. Don't eat a large, heavy dinner. If you opt for a late dinner, eat a larger lunch and keep dinner light. Avoid drinking too much alcohol. If you do drink, have just one or two, and enjoy them well before bedtime. Make your bed away from home more comfortable. Pack some ear plugs, a sleep mask and something from home, such as lavender spray or a white noise machine. Read more

Need to Boost Your Memory? Then Get Your Zzzz's

Posted 1 Jan 2016 by

THURSDAY, Dec. 31, 2015 – A good night's sleep can help you remember new faces and names, researchers report. The researchers showed 20 photos of faces with matching names to 14 volunteers in their 20s. Twelve hours later, participants were shown the photos again and asked if the faces and names matched. The test was done twice – once after the participants had slept for up to eight hours and once with a period of regular day activities in between. After sleeping, the participants correctly matched 12 percent more of the faces and names. How long or how deeply volunteers slept did not influence their ability to match faces and names. But, more research is needed to find out if these factors are important, according to the authors of the study published recently in the journal Neurobiology of Learning and Memory. "We know that many different kinds of memories are improved with sleep. ... Read more

Health Tip: Sounds May Help You Fall Asleep

Posted 25 Dec 2015 by

-- When you want a bit of help to nod off, some soft background noise may be just what you need. The National Sleep Foundation suggests: Try white noise, which combines different sounds at different frequencies. You can use a white noise app on your smart phone or buy a white noise machine (sometimes called a sound conditioner). Consider the soothing sounds of nature, from raindrops to rolling ocean waves. Avoid sounds that may be jarring. Turn on soft music, particularly light jazz, classical, Gregorian chants or folk music. Avoid loud music or with lyrics that may distract you. If you find human voices soothing, try apps that play a soothing voice repeating nonsensical phrases. Read more

Night-Shift Workers May Be Prone to Car Crashes

Posted 22 Dec 2015 by

TUESDAY, Dec. 22, 2015 – In a study of 16 night-shift workers, more than one-third were involved in near crashes while participating in a test drive after work, researchers report. The same drivers experienced zero near-crashes after sleeping sufficient amounts the night before the same test drive, according to the study, published online Dec. 21 in the Proceedings of the National Academy of Sciences. "What is unique about this study is that it (was) done in daytime" and there was a "stupendously increased risk of these near-crash events," said study author Dr. Charles Czeisler, chief of the division of sleep and circadian disorders at Brigham and Women's Hospital in Boston. "It reveals just how dangerous it is to drive home after working all night," added Czeisler, also a professor of sleep medicine at Harvard Medical School in Boston. "It also shows that these very same people, if ... Read more

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
