Study: Brain cells’ reaction to light behind sleep patterns

92250468The way a person’s brain is wired can have a significant impact on the way we go about our daily lives. The discoveries of a new study supporting this concept have revealed that certain types of cells found in the human brain are behind our sleep patterns.

In a study by researchers at the University of California Los Angeles (UCLA), the findings showed that brain cells create a substance – called hypocretin – that keeps an individual awake in conditions of bright light. Conversely, this substance isn’t created at the same level in darkness, making individuals feel sleepy and ready to doze off in their white beds.

The findings also suggested that a person’s failure to produce sufficient amounts of hypocretin could increase the risk of sleep disorders and even Parkinson’s disease down the line.

Jerome Siegel, study author and professor of psychiatry at the Semel Institute for Neuroscience and Human Behaviour at UCLA, said: “This current finding explains prior work in humans that found that narcoleptics lack the arousing response to light, unlike other equally sleepy individuals, and that both narcoleptics and Parkinson’s patients have an increased tendency to be depressed compared to others with chronic illnesses.”

Nicole Kidman and Naomi Watts to record bedtime stories

stk85221corHollywood actresses Nicole Kidman and Naomi Watts are to contribute their unique Aussie drawls to a new series of audio books dedicated to aiding sleep, according to recent reports.

Reading before bed is a tried-and-tested method of encouraging sleep on restless nights, and in an article by The Sydney Morning Herald published today (October 4th), it is revealed that a star-studded line-up of celebrities will offer their trademark voices to do the reading for you.

Kidman, 44, is to read Virginia Woolf’s novel To the Lighthouse, which is based in early twentieth century Isle of Skye, Scotland. Meanwhile, King Kong star Watts, 43, will offer her talents in the reading of Summer by Edith Wharton; another popular classic that depicts early upper-class New York society.

Top tips to make your bedroom feel bigger

83886044People often struggle to get the most out of the space in their bedroom, though with a few easy tips, it’s easy to stay on top of things and keep your sleeping space feeling open, fresh and relaxing.

Firstly, remove as much clutter as possible. The more items that are in your bedroom, the more cramped it feels. If you look around the room and can’t see the floor, you have too much furniture or personal belongings. Try to use any unnecessary furniture in another room of the house and remove large collections of personal belongings to create the illusion of space.

Buy furniture that instead maximises wall space; small bedrooms are more suited to shelves, flatter wardrobes and other items that allow you to have floor space in front of them. From here, it is important to scale decor by the size of a bed, which will likely be the focal point of the room. If you have a large bed, get table lamps and decorations that are in proportion to it.

Finally, choose colour schemes wisely. Dark shades in a small room can make bedrooms feel closer and more oppressive; try to keep them to accessories like pillows, rugs and accents in drapery or bed linen. Lighter colours on walls will give a greater illusion of space.

TV may give toddlers terrible sleep

100176590Young children who are exposed to violent images on TV and computer games can experience serious sleep disruption, according to a new study.

Research conducted by the Seattle Children’s Research Institute in Seattle, which is published in the July issue of Pediatrics, suggests that children sleep poorly if exposed to this kind of screen time.

What’s more, the study which used 612 sleep and media diaries prepared by parents to assess sleep and media viewing, found that any sort of viewing time in the evening had a detrimental effect on sleep.

“The bottom line is that we see violent media use [in the daytime] and any screen time at all in the evening is associated with a negative impact on sleep in kids of this age,” said Michelle Garrison, PhD, and colleagues at the Seattle Children’s Research Institute in Seattle.

The diaries showed that children were viewing a TV screen or a computer for around 73 minutes on average every day.

Scottish teens to get sleep lessons

sb10069478h-001Teenagers across Scotland could soon be taking lessons in how to sleep alongside double maths and Science thanks to a specialist charity.

Following trials last year which took place in secondary schools in Glasgow, the BBC reports that Sleep Scotland are to send teaching packs to schools with the aim of giving teachers the resources to teach children how to get enough sleep.

Sleep Scotland carry out sleep research and also offer a counselling service to help those with sleep difficulties to tackle sleep problems and get a better night’s rest.

Talking to the BBC about the new schools initiative, Jane Ansell, director of Sleep Scotland, said: “I don’t think any parent would think of sending out their child without enough food in the morning, or decent clothing, and they know how important reasonable exercise is, so why should you send your child out without enough sleep?”

Screens could be stopping sleep

77005750We all love the convenience of modern gadgets, but our use of technology could be preventing us from getting enough sleep according to research.

A poll conducted on behalf of the US National Sleep Foundation found that 95 per cent of Americans use at least one kind of electronic item before bed, with six in ten admitting that they use their laptops or computers within the hour before they hit the sack at least a few nights per week.

Experts fear these late night sessions could be detrimental to sleep levels, with 24 per cent of Americans reporting that they rarely or never get enough sleep on weeknights.

Charles Czeisler, PhD, MD, Harvard Medical School and Brigham and Women’s Hospital said: “Artificial light exposure between dusk and the time we go to bed at night suppresses release of the sleep-promoting hormone melatonin, enhances alertness and shifts circadian rhythms to a later hour — making it more difficult to fall asleep”.

Brits love a little light reading before bedtime

77006084Research conducted to coincide with World Book Day last week has revealed that two-thirds of adults drift off to sleep after reading six and a half pages of a standard-sized paperback.

A poll of 3,000 Brits carried out by the publisher Routledge found that the average Brit reads 2,134 words before sloping off to slumberland – perhaps a tad more than the term ‘light bedtime reading’ suggests.

Intellectual books such as autobiographies were said to be the preferred option for promoting sleep and helping people to drop off.

A spokesman for Routledge said:  ”A good book is the ideal form of escapism, and is the perfect antidote to a long, hard and stressful day at the office.

”Reading also exercises the grey matter, which may explain its soporific effects  – especially at bedtime.”

Naps have positive cardiovascular impact

Spa salon #25Taking an hour long nap in the afternoon could help lower blood pressure and relieve stress according to new research from the US.

Investigations by Ryan Brindle and Sarah Conklin, PhD, from Allegheny College Pennsylvania, found that individuals who snoozed for between 45 minutes and an hour in the daytime had lower average blood pressure  than those that did not.

Modern pressures such as shift work, increased anxiety and the use of television and internet before bed have all made an impact on nocturnal sleep and the average sleep is now two hours shorter than half a century ago.

Brindle and Conklin said: “Our findings suggest that daytime sleep may offer cardiovascular benefit by accelerating cardiovascular recovery following mental stressors.”

The research team went on to say further study was needed to establish if siestas could be used as a “recuperative” or “protective” measure to aid cardiovascular health.

Women struggle to sleep after tipple

200287703-001Heavy drinking on an evening not only leaves you with a stonking headache the next morning; a recent study has revealed that it can also disrupt a peaceful night’s sleep.

Experts at the University of Michigan assessed 34 men and 59 women, between 21 and 29 years of age, and found that sleeping soundly in bed after a night of excessive drinking is much more difficult for women than it is for their male counterparts.

Female participants woke up more frequently than the men throughout the night and had fewer hours of good quality sleep as a result.

“We predicted that sleep would be worse in women because women metabolise alcohol quite differently,” commented J. Todd Arnedt, director of the university’s behavioural sleep medicine programme.

Teenage girl shares her bed with tiger

sb10069719ag-001Sharing a bed with someone can be frustrating and a hindrance to a peaceful night’s sleep. But Florida teen Felicia Frisco, 17, has been sharing her bed with a Bengal tiger since the day he was born – and she loves it!

Will, the six-month-old tiger, was bred in captivity by Felicia’s parents who run an educational project called Tiger Encounter.

Each night she climbs into bed with her pet and will continue to do so until he’s a year old.

Felicia doesn’t seem to mind her nightly battles over bed space. She told Peoplepets.com: “I’m very protective of him and I always want to be around him. He was so small, and watching him get so big, it’s kind of like having a child.”
