Poor sleep linked to illness in new study

81264406Scientists in the US have recently discovered that less time spent in leather, metal or oak beds could result in illnesses along the line. Researchers from Yale University have discovered that the circadian clock – the genetic system that regulates sleep on a day-to-day basis – is also linked to the level of TLR-9 in the body, which is vital to the immune system.

TLR-9 was tested in mice to discover that when the gene was at its optimal amount, it responded better to bacteria and viruses, while the mice themselves were able to deal with infection and vaccinations much more effectively. In principle, this should also apply to humans.

Reporting their findings in the journal Immunity, it was further argued that disruptions to this circadian rhythm can make people more likely to contract, or suffer worse from, illness. Issues that were of particular concern included jetlag and the timing of when people ought to receive vaccinations.

Professor Erol Fikrig, who worked on the paper, said: “Sleep patterns of patients in intensive care are often disrupted because of the noise and prolonged exposure to artificial light. It will be important to investigate how these factors influence immune system response.”

Teens ‘may need less sleep than originally thought’

86521872Students who think that a long sleep in on the day of a test is better for their grades may be shocked to find out that added rest could actually hurt a teen’s marks, meaning they ought to spend less time in their double or single bed prior to doing their exam.

A new study published in the Eastern Economics Journal discovered that more conventional wisdom may not necessarily be correct. Despite guidelines in the US – where the research was carried out – recommend nine hours of sleep a night, it may in fact be way too much.

It was discovered by Eric Eide and Mark Showalter – economics professors at Brigham Young University – that students between 15 and 18 ought to target seven hours a night, following analysis of sleep and standardized test scores that existed before the study.

The study also went on to show that the amount of sleep necessary for better grades generally declined with age – 16-year-olds were found to need around two hours less than ten-year-olds.

Is there a link between sleep problems and memory loss?

expressive seniorIndividuals who have sleep problems may be at a greater risk of suffering from memory deterioration like Alzheimer’s disease later down the line, according to new research.

In a study of 100 participants conducted by the Washington University School of Medicine, it was revealed that individuals who woke more than five times in an hour each night while in bed were at a higher risk of developing a build-up of amyloid plaques in the brain – a common symptom of Alzheimer’s.

Though the evidence sheds some light on the relationship between our sleep quality and memory and has the potential to help prevent future cases of Alzheimer’s, lead author of the study Yo-EL Ju from the school explained that the research is not yet conclusive.

He commented: “We need longer term studies to determine whether disrupted sleep leads to amyloid plaques, or whether brain changes in early Alzheimer’s disease lead to changes in sleep.”

Is George Clooney feeling sleepy?

57564227Movie star and ladies’ man George Clooney has admitted that he’s “lonely” and has “a very tough time getting to sleep” sleeping in his king size bed.

In an interview with The Hollywood Reporter, the Ides of March actor talked about being single and how he has difficulty switching off from the world and as a result often wakes up five times every night.

Despite having women throwing themselves at his feet, the 50-year-old confessed that he feels lonely every so often, especially at public events.

Clooney, who has dated the likes of Italian actress Elisabetta Canalis and British presenter Lisa Snowdon in the past, said: “Anyone would be lying if they said they didn’t get lonely at times.

“The loneliest you will get is in the most public of arenas: You will go to a place and end up in the smallest compartment possible, because it’s a distraction to everybody, and you end up not getting to enjoy it like everyone else.”

Portrait photographer shoots cute sleeping babies

99273859Newborn babies don’t have to try hard to be adorable and popular photographer has caught a selection of babies at their cutest: the very moment they drift off to sleep in their bed.

In an interview with the MailOnline published yesterday (February 14th), Dan Cueller, a 29-year-old baby portrait photographer, explained the process he goes through for each shot including each baby receiving a four hour pampering session. The babies are fed and cuddled until they feel relaxed and gradually become sleepy.

Mr Cueller, who became a professional photographer three years ago, commented: “Newborns are naturally cute and they can’t really do much at this age.

“You can’t just ask a baby to do something, so it’s usually best and easier to pose them when they are asleep.”

The accompanying images to the article show numerous babies curled up and content in slumberland.

He continued: “The age of the child is also very important – it’s usually best to photograph them when they are under two-weeks-old.”

Have our kids ever got enough sleep?

86533542For parents, getting their children into their children’s beds at an appropriate hour can be one of the biggest challenges mums and dads face. What’s more, even when kids are tucked under the covers, there is no guarantee that they’re going to get the quality of sleep they need to grow big and strong. Indeed, a new study claims that, historically, youngsters have consistently got less sleep than the recommended guidelines – for the past 100 years, at least.

Researchers from the University of South Australia did some digging into all the past studies about sleep duration in children, beginning at the end of the 19th century and through to 2009.

After uncovering 300 studies, they found that both age-specific recommendations for good sleep and the amount of time children actually spend asleep in their beds declined at similar rates. The findings, which are to be published in the journal Pediatrics on Monday (February 20th), showed there was a drop of 0.71 minutes per year for recommendations and 0.73 minutes per year for sleep duration. Meanwhile, across the board, youngsters got around 37 minutes less sleep than recommendations suggested.

Sleep texting on the rise, says expert

137003524Mobile phones are an integral part of most individuals’ lives and it seems so much so that a number of us struggle to switch off from using these devices as we snooze with sleep texting cases now on the rise, says a leading sleep doctor.

In an interview with Kare 11 news, Dr Mike Howell, sleep specialist at the University of Minnesota Sleep Medicine Clinic, claimed that the phenomenon of sleep texting is becoming particularly prevalent among young people as they sleep in their single beds - a demographic that arguably spends the most time on mobile phones during the day.

He explained that the activity occurs during the transition period between being awake and being asleep and that the there is a greater risk of it being extended if an individual is sleep deprived.

Consequently, mobile owners who have found they’ve texted when they thought they were fast asleep may find that this behaviour may be eradicated, or at least limited, if they get better quality sleep, Dr Howell concluded.

Action heroes Schwarzeneggar and Stallone reunited in bed

93424741There could be one of a number of impressive ways that action heroes Arnold Schwarzeneggar and Sylvester Stallone reunite for the first time in years, but the reality is that they’ve done so in their single beds while in hospital!

Veteran movie star “Arnie”, who is also the former governor of California, recently posted a photograph of himself and his Hollywood pal lying beside each other and cracking jokes in their hospital beds on his Whosay account page.

The pair were allegedly being treated for stunt-related injuries, but some sceptics have questioned the authenticity of the situation. Suspicion stirred after the photos were posted just a few hours after the announcement that Arnie is to co-star with Stallone – best known for his performances in Rambo and Rocky – in forthcoming movie The Tomb.

In an accompanying comment to the photo, 64-year-old Schwarzeneggar said: “After all the action, stunts and physical abuse shooting The Expendables 2 and The Last Stand, it was time for a little tune up on my shoulder. Look who was coincidentally waiting in line behind me for his shoulder surgery.”
