Sleep apnoea linked to changes in brain structure
The changes in the brain that cause these cognitive effects are little understood, and studies into links between sleep apnoea and changes in brain structure have so far yielded conflicting results. Now, research from the UK and Australia has reinforced the idea that there are differences in brain structure between people with sleep apnoea and healthy controls, although more work is needed to understand how these differences affect brain function. For the study, 60 people with severe sleep apnoea were recruited from sleep clinics at the Royal Brompton and Charing Cross Hospitals in London and Austin Health, Melbourne, alongside 60 healthy controls. The researchers used magnetic resonance imaging to compare the volume of grey matter in the two groups. Compared with controls, people with sleep apnoea had significantly reduced amounts of grey matter in the temporal lobe and the cerebellum.
Exercise: a requirement for sleep?
Recently I have struggled to get to sleep at night. When I need to be up at 8 and working away on either my own projects or exciting client projects by 9 it is vital that I wake up refreshed and ready for a challenging day. So why am I having trouble sleeping? As a result, I’ve not been exercising as much as I usually do. I am now starting to think that exercise is not something that can take a lower priority when things get busy. Tired?Two case reports demonstrate the impact that sleep apnea may have on perilymph fistula syndrome, in both relatively acute and more chronic situations. Though the vestibular system in humans is primitive, it is, nonetheless, essential for functioning in earth’s gravitational field. Considerable animal research on vestibular function during sleep has been completed, 1 but relatively little work has been done in humans.

Sleep: The secret to a sound sleep lies inside the brain, researchers find - latimes.com
I am frequently amazed by my husband's ability to sleep through all kinds of noises that cause me to wake in a flash -- car alarms, smoke detectors that are running low on batteries, and especially kids who have lost track of their favorite blankie in the middle of the night. Thanks to a new study being published in Tuesday's edition of the journal Current Biology, I now know that his brain probably produces more sleep spindles than mine. You see, while we're sleeping, the thalamus -- the part of the brain that receives sensory input like sounds -- tries to relay information to the cortex , where the sounds are actually perceived.
DARIEN, Ill. – A study in the Aug. 1 issue of the journal Sleep suggests that a dose of extra sleep on the weekend may be good medicine for adults who repeatedly stay up too late or wake up too early during the workweek. However, even a night of 10 hours in bed may not be enough to cure the negative effects of chronic sleep restriction. Results show that neurobehavioral impairments such as increased lapses of attention and delayed reaction times accumulated across a period of five days when sleep was restricted to less than four hours per night. Behavioral, subjective and physiological measures of alertness improved significantly after a night of recovery sleep, with larger doses of sleep producing greater gains. Yet some neurobehavioral deficits continued to linger after the maximum recovery dose of 10 hours in bed, during which participants slept for an average of about nine hours.

How much sleep is enough? Is how sleepy you feel a good judge of whether or not you are getting enough sleep? If you get less sleep than some ideal amount but you feel fine, could you be damaging your health anyway?

6-7% of adults report delayed sleep phase syndrome and 17% of university students have symptoms that qualify (from a recent study ). My sense is that entrepreneurs, through both cause and correlation, have significantly higher rates of insomnia than the general population. I'll talk a lot more about this relationship in a future post, but the anecdotal evidence of morning-hating entrepreneurs is not difficult to find .

What does your sleep position reveal about your personality? - Healthy Living on Shine
These days, the way that I sleep simply says, "I am happy to be single and spending five to seven hours sprawled out in the center of my bed alone." At other points, my tightly squeezed eyes and curled-up body would have screamed, "I know the baby will wake up/someone will start snoring/the alarm will begin blaring as soon as I finally, finally, finally get to sleep." Years and years ago, the corpse-looking college student still in her clothes would have mumbled something like, "Finals. Boys. Beer." Our lives, the amount of sleep we get, and how well we actually rest during those nighttime hours may change drastically over time.After publishing Good sleep, good learning, good life , we have received lots of mail with requests to clarify some of the complexities of sleep theory.

Lack of morning light keeping teenagers up at night
Public release date: 16-Feb-2010 [ Print | E-mail | Share ] [ Close Window ] Rensselaer Polytechnic Institute Troy, N.Y - The first field study on the impact of light on teenagers' sleeping habits finds that insufficient daily morning light exposure contributes to teenagers not getting enough sleep. "As teenagers spend more time indoors, they miss out on essential morning light needed to stimulate the body's 24-hour biological system, which regulates the sleep/wake cycle," reports Mariana Figueiro, Ph.D., Assistant Professor and Program Director at Rensselaer Polytechnic Institute's Lighting Research Center (LRC) and lead researcher on the new study.
