Apnea

40 Sleep Hacks: The Geek's Guide to Optimizing Sleep. Sleep apnoea linked to changes in brain structure. Obstructive sleep apnoea occurs when someone stops breathing while sleeping, because their airway at the back of the throat becomes blocked. This can lead to excessive sleepiness, increased risk of stroke and heart attack, and cognitive impairment. 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.

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? Busy lifestyle pushes exercise aside In the last few weeks I’ve found myself a lot busier than usual - client projects and multiple side projects of my own. 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? I’m mentally drained from the day’s work, but physically I have just been sat at a desk all day and I have too much energy to fall asleep. Does exercise have an impact?

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. Sleep experts can see these transmissions on an electroencephalography test, or EEG. But, scientists believe, sometimes the brain throws up roadblocks to prevent the cortex from being disturbed during crucial periods of sleep when memories are consolidated. The report is online here. -- Karen Kaplan. One Night Of Sleep Not Enough To Make Up Deficit. One Night Of Sleep Not Enough To Make Up Deficit 10 hours of sleep isn't enough to recharge your brain after 5 days of sleep deficit.

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. As the researchers point out, the body's circadian rhythm will probably prevent a lot of people from even getting 10 hours. The Surprising Toll of Sleep Deprivation. Become a morning person. How to end insomnia for $520.99. 6-7% of adults report delayed sleep phase syndrome and 17% of university students have symptoms that qualify (from a recent study).

The research also links certain sleeping positions with health risks. [graphic via BBC.com] Let's see how the Shine readers are resting these days. SleepChart: Formula for Healthy Sleep. The cycle of sleep and waking is regulated by the body clock. Body clock is located in the brain (suprachiasmatic nucleus). The clock has a period of about 24 hours. During a single 24 hour day we have a period of 6-10 hours when we are very sleepy.

This is the time when we normally sleep. During the remaining 14-18 hours we are usually awake; however, only a portion of that waking time is suitable for intellectual effort. This period of maximum alertness may last as little as 2-6 hours. Delayed Sleep Phase Syndrome Delayed Sleep Phase Syndrome (DSPS) is a sleep disorder in which an individual finds it difficult to fall asleep late in the night, and sleeps well into the afternoon if not awakened. The main factors contributing to DSPS: increased period of the body clock (well above 25 hours) reduced or increased sensitivity to factors that reset or advance body clock (e.g. light, activity, stress, etc.) electric lighting, 24-hour economy and the resulting "want to do more" lifestyle.

Public release date: 16-Feb-2010 [ Print | E-mail Share ] [ Close Window ] Contact: Mary Cimocimom@rpi.edu 518-687-7174Rensselaer 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. "These morning-light-deprived teenagers are going to bed later, getting less sleep and possibly under-performing on standardized tests. We are starting to call this the teenage night owl syndrome.

Sleep on It: How Snoozing Makes You Smarter. In 1865 Friedrich August Kekulé woke up from a strange dream: he imagined a snake forming a circle and biting its own tail.

Like many organic chemists of the time, Kekulé had been working feverishly to describe the true chemical structure of benzene, a problem that continually eluded understanding. But Kekulé’s dream of a snake swallowing its tail, so the story goes, helped him to accurately realize that benzene’s structure formed a ring. This insight paved the way for a new understanding of organic chemistry and earned Kekulé a title of nobility in Germany. Although most of us have not been ennobled, there is something undeniably familiar about Kekulé’s problem-solving method. Whether deciding to go to a particular college, accept a challenging job offer or propose to a future spouse, “sleeping on it” seems to provide the clarity we need to piece together life’s puzzles.

The average newborn sleeps much of the day and night, waking only for feedings every few hours. It is often hard for new parents to know how long and how often a newborn should sleep. Unfortunately, there is no set schedule at first and many newborns have their days and nights confused - they think they are supposed to be awake at night and sleep in the daytime.

Generally, newborns sleep about eight to nine hours in the daytime and about eight hours at night. Most babies do not begin sleeping through the night (six to eight hours) without waking until at least three months of age, or until they weigh 12 to 13 pounds. However, this is very variable and some babies do not sleep through the night until closer to one year. Watch for changes in your baby's sleep pattern. Never put a baby to bed with a bottle propped for feeding. What are the sleep states of a newborn? Babies, like adults, have various stages and depths of sleep. Helping your baby sleep.

Science of Sleep- Columbian.com. Polyphasic Sleep. A couple days ago, I saw a post about polyphasic sleep on LifeHack.org. Since then I’ve been emailed about this topic as well, probably because I’ve written previously about becoming an early riser.

Polyphasic sleep involves taking multiple short sleep periods throughout the day instead of getting all your sleep in one long chunk. A popular form of polyphasic sleep, the Uberman sleep schedule, suggests that you sleep 20-30 minutes six times per day, with equally spaced naps every 4 hours around the clock. This means you’re only sleeping 2-3 hours per day. I’d previously heard of polyphasic sleep, but until now I hadn’t come across practical schedules that people seem to be reporting interesting results with. Under this sleep schedule, your sleep times might be at 2am, 6am, 10am, 2pm, 6pm, and 10pm.

And each time you’d sleep for only 20-30 minutes. How can this sleep schedule work? It was interesting to read some of the posts from people who’ve tried this sleep cycle. Sleep well! Tips for getting to sleep faster & sleeping better. By Josh For practically all my life I’ve had trouble going to sleep. I’m not an insomniac…I just think a lot. I’ll lie in bed thinking about what I want to do tomorrow or what I should have done today or how much I love eating cold pizza or how absurdly messy my desk is….you get the idea. And when I say I have trouble going to sleep…I’m not talking 20 or 30 minutes…I’m talking 2 or 3 hours. Because what will happen is after about 45 minutes to an hour of trying to go to sleep, I start thinking about how I’m not asleep but I should be…and thus the cycle begins.

Now, I may be a bit of an extreme case here, but I know for a fact that there are others out there who have trouble going to sleep. Don’t watch TV or even so much as look at a computer screen atleast 30 minutes before you lie down. These are the majority of the things I have either tried or actually do routinely. Psychology Today: How to Get Great Sleep. Blame it on the Industrial Revolution. Or maybe on the light bulb. But ever since man met machine, sleep has been on the skids. In 2001, 38 percent of U.S. adults said they were sleeping less than they were just five years earlier. Americans now average seven hours in bed per night, and close to 60 percent now report they have trouble sleeping at least a few nights every week.
