Newborn - Sleep Patterns - Lucile Packard Children's Hospital What are the sleep patterns of a newborn? 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. 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. REM (rapid eye movement sleep). What are the different alert phases of a newborn? Babies also have differences in how alert they are during the time they are awake. It is usually best to feed babies before they reach the crying phase. Helping your baby sleep A task force of The U.S.
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. Under this sleep schedule, your sleep times might be at 2am, 6am, 10am, 2pm, 6pm, and 10pm. How can this sleep schedule work? It requires some discipline to successfully transition to this cycle, as well as a flexible schedule that allows it. It was interesting to read some of the posts from people who’ve tried this sleep cycle. The downside to this sleep schedule is that it can be inflexible. Plus it’s just plain weird. Sleep well!
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.

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. 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. Seduced by 24-hour casinos, reruns and the Internet, Americans have plenty of diversions to keep them wired and alert. The biggest sleep robber of all, however, is work—the puritan ethic gone haywire in an era of global markets. To some degree, we can sacrifice sleep to oblige other demands on our time, but we pay a high price for the privilege. What we do at night affects everything we do during the day—our ability to learn, our skills, our memory , stamina, health and safety. Everyone has a troubled night sometimes, or even a run of them, which happens to the average person about once a year.

Lack of morning light keeping teenagers up at night 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.

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. 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 A normal individual has a body clock running with a period slightly longer than 24 hours. If this description fits your problem, you may diagnose the degree of your DSPS with SleepChart freeware at the bottom of this article. 24 hour cycle.
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. Our lives, the amount of sleep we get, and how well we actually rest during those nighttime hours may change drastically over time. Professor Chris Idzikowski, director of the Sleep Assessment and Advisory Service, says that a study of 1,000 Brits revealed that the six most common sleeping positions are indicative of personality types. "We are all aware of our body language when we are awake but this is the first time we have been able to see what our subconscious posture says about us," Idzikowski said.
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). 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. If you're like me, you've tried lots of different methods. I've bought virtually every gadget out there and seen lots and lots of doctors. Here's how I did it: 1. 2. It's actually that simple. It took me years, but I've now found the right mix of gadgets and systems to duplicate this success: 1. This is super important. Let's be real here though, I'm not turning off my lights or living by candle light. For the computer, I use a program called f.lux. I double up with a physical filter as well. Low Blue Lights also sells red light bulbs that you can use as a reading light. 2.
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. As the researchers point out, the body's circadian rhythm will probably prevent a lot of people from even getting 10 hours. Brain performance decayed each day over 5 days of insufficient sleep. Mean total sleep time dropped from 8.47 hours at baseline to 3.72 hours on the first night of sleep restriction. If you are pushing yourself to get a lot done at work and with home responsibilities your productivity could be falling enough to cancel out the additional hours worked. Boy, would I love to sleep from 10-6 or 11-7.
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. 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. These roadblocks are sleep spindles, which also have a characteristic appearance on an EEG. -- Karen Kaplan
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? 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. 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? After around a week and a half away from the gym, one evening I decided enough was enough and I went and swam 50 lengths. A simple search on Google reveals many results similar to this one: Exercise is important for a healthy life. Quality of sleep That point could easily be overlooked in that last quote.

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. Compared with controls, people with sleep apnoea had significantly reduced amounts of grey matter in the temporal lobe and the cerebellum. The condition is thought to affect around 2-4 per cent of younger adults and over 15 per cent of elderly people.
