Sleep deprivation handicaps the brain's ability to form new memories   Science Daily - February 2, 2017
Studying mice, scientists have fortified evidence that a key purpose of sleep is to recalibrate the brain cells responsible for learning and memory so the animals can 'solidify' lessons learned and use them when they awaken -- in the case of nocturnal mice, the next evening. The researchers, all of the Johns Hopkins University School of Medicine, also report they have discovered several important molecules that govern the recalibration process, as well as evidence that sleep deprivation, sleep disorders and sleeping pills can interfere with the process.




New study illuminates key aspects of how we fall asleep and wake up   Medical Express - April 14, 2016
Falling asleep and waking up are key transitions in everyone's day. Millions of people have trouble with these transitions - they find it hard to fall asleep or stay asleep at night, and hard to stay awake during the day. Despite decades of research, how these transitions work - the neurobiological mechanics of our circadian rhythm - has remained largely a mystery to brain scientists.




How the brain consolidates memory during deep sleep   Medical Express - April 14, 2016
Research strongly suggests that sleep, which constitutes about a third of our lives, is crucial for learning and forming long-term memories. But exactly how such memory is formed is not well understood and remains, despite considerable research, a central question of inquiry in neuroscience.

Why Does the Sound of Water Help You Sleep?   Live Science - January 18, 2016

The crash of ocean waves, the babbling of brooks, the pitter-patter of rain on shingles - many people swear by these watery sounds to help them fall asleep and stay in la-la land. Why does flowing "agua" apparently have such a powerful and popular drowsing effect? Part of the answer lies in how our brains interpret the noises we hear - both while awake and in the dead of night - as either threats or non-threats. Certain sounds, such as screams and loud alarm clocks, can hardly be ignored. Yet other sounds, like the wind in the trees and waves lapping ashore, we sort of tune out.




This reason this occurs is ... the body has turned to food for the fuel it should get with proper sleep.

Lack of Sleep May Increase Food Cravings   Epoch Times - January 3, 2016

Did you know that less sleep can lead to more food cravings? ThatŐs right. Studies show that just one sleepless night can affect the brainŐs response to food the next day, increasing your desire to eat. Therefore, a person who doesnŐt sleep well one night may crave more food than normal the next day. One study looked at the eating habits of around 40 healthy people between the ages of 21 and 50 who followed regular sleep schedule of six to eight hours of sleep a night. Those who were sleep-deprived during the study ate almost 1,000 more calories than they usually would the next day. They also ordered more fatty foods and more carbs.

Surprising Ways Too Much Sleep Is Hurting Your Health   Huffington Post - December 21, 2015

It's a little hard to believe there's such a thing as sleeping too much, since so many of us feel like it's a struggle to even get barely enough. But it's true: You can overdo it on sleep. While it's tough to pinpoint the "just right" amount, most adults need between seven and nine hours a night to feel and function their best. Regularly logging more than nine hours of sleep a night may be a sign of an underlying medical condition, but it also puts you at risk for a whole host of health concerns. Here are some of the biggest risks of catching too many Zzs.
Sleeping too much can raise depression risk.
It could impair the brain.
It might make it harder to get pregnant.
Sleeping too much can increase diabetes risk.
It can lead to weight gain.
It can hurt the heart.
It may lead to an earlier death.

One night of sleep loss can alter clock genes in your tissues   PhysOrg - July 20, 2015

Previous research has shown that our metabolism is negatively affected by sleep loss also linked to an increased risk of obesity and type 2 diabetes. Since ablation of clock genes in animals can cause these disease states, our current results indicate that changes of our clock genes may be linked to such negative effects caused by sleep loss. The researchers do not at this stage know how persistent these changes are. It could be that these changes are reset after one or several nights of good sleep. On the other hand, epigenetic marks are suggested to be able to function a sort of metabolic memory, and have been found to be altered in e.g. shift workers and people suffering from type 2 diabetes.

Here's What Lack Of Sleep Can Do To You In Just One Day   Huffington Post - June 11, 2015

For years, studies have linked lack of sleep with poorer cognitive performance. Now there's another good reason to get enough shut-eye: Just one bad night's sleep can make older adults age faster. Our data support the hypothesis that one night of not getting enough sleep in older adults activates important biological pathways that promote biological aging.




Study unites neuroscience and psychology to paint more complete picture of sleep and memory   PhysOrg - June 11, 2015
A new study from the Florida campus of The Scripps Research Institute (TSRI) integrates neuroscience and psychological research to reveal how sleep is more complex than the Bard might have imagined. The new research shows in animal models that sleep suppresses the activity of certain nerve cells that promote forgetting, insuring that at least some memories will last. We have revealed that one of the ways sleep protects a new memory is by quieting dopamine neuron activity that causes forgetting. Since laboratory animals and humans share a need for sleep, as well as many genetic and circuit mechanisms underlying learning and memory, our findings may shed light on the mechanisms underlying the interaction between sleep and memory in humans.

Why a long night's sleep may be bad for you   BBC - March 25, 2015

Many of us try, but often fail, to get eight hours' sleep each night. This is widely assumed to be the ideal amount - but some experts now say it's too much, and may actually be unhealthy. We all know that getting too little sleep is bad. You feel tired, you may be irritable, and it can contribute to obesity, high blood pressure, diabetes, and heart disease, doctors say. But too much sleep? You don't often hear people complaining about it. However, research carried out over the past 10 years appears to show that adults who usually sleep for less than six hours or more than eight, are at risk of dying earlier than those sleep for between six and eight hours.

Mindfulness Meditation May Help Older Adults Sleep Better   Live Science - February 16, 2015
Meditating may help older adults sleep better, a new study suggests. The study involved about 50 adults in Los Angeles ages 55 and older who had trouble sleeping, including difficulty falling asleep or staying asleep, or who felt sleepy during the day. Participants were randomly assigned to complete either a mindfulness meditation program - in which people learn to better pay attention to what they are feeling physically and mentally from moment to moment - or a sleep education program that taught the participants how to develop better sleep habits. The participants also completed a questionnaire to assess how well they were sleeping, and were given a score from 0 to 21, with higher scores indicating worse sleep.




Sleepless in High School: Teens Getting Less Shut-Eye   Live Science - February 16, 2015
The amount of time that teens spend sleeping has substantially declined over the last 20 years, a new study suggests. The results from a large national survey show that the percentage of U.S. teenagers who regularly get seven or more hours of shut-eye is consistently decreasing. For example, surveys of teens done in the early 1990s showed that about 52 percent of 15-year-olds reported getting at least seven hours of sleep, whereas in 2011-2012, just 43 percent of 15-year-olds said the same. About 36 percent of 18-year-olds said they got at least seven hours of sleep in the early 1990s, but in 2011-2012, only about 33 percent did.

Can poor sleep lead to dementia?   PhysOrg - December 10, 2014
People who have sleep apnea or spend less time in deep sleep may be more likely to have changes in the brain that are associated with dementia. The study found that people who don't have as much oxygen in their blood during sleep, which occurs with sleep apnea and conditions such as emphysema, are more likely to have tiny abnormalities in brain tissue, called micro infarcts, than people with higher levels of oxygen in the blood. These abnormalities are associated with the development of dementia.

No sedative necessary: Scientists discover new 'sleep node' in the brain   Science Daily - September 19, 2014
A sleep-promoting circuit located deep in the primitive brainstem has revealed how we fall into deep sleep. This is only the second 'sleep node' identified in the mammalian brain whose activity appears to be both necessary and sufficient to produce deep sleep. Tthe study demonstrates that fully half of all of the brain's sleep-promoting activity originates from the parafacial zone (PZ) in the brainstem. The brainstem is a primordial part of the brain that regulates basic functions necessary for survival, such as breathing, blood pressure, heart rate and body temperature.




Americans Are Popping Sleeping Pills in Record Numbers   Epoch Times - September 10, 2014
In the face of growing evidence that sleep drugs cause people to be unsafe drivers even the next day, the FDA has once again required a dose reduction for a popular sleeping pill. A year and a half ago, the FDA announced that it would require the makers of sleep drugs, including those that contain the ingredient zolpidem (used in popular brands, such as Ambien), to reduce the recommended dose for women. The decision was spurred by studies showing that 15% of women who took such drugs still experienced impaired driving eight hours later to a degree that increases the risk of a motor vehicle accident. The same degree of impairment was seen in 3% of men. The percentages were even higher among women and men who took the extended release version of the drug.

Why Does Sleeping In Just Make Me More Tired?   Wired - July 22, 2014

Oversleeping feels so much like a hangover that scientists call it sleep drunkenness. But, unlike the brute force neurological damage caused by alcohol, your misguided attempt to stock up on rest makes you feel sluggish by confusing the part of your brain that controls your body's daily cycle. Your internal rhythms are set by your circadian pacemaker, a group of cells clustered in the hypothalamus, a primitive little part of the brain that also controls hunger, thirst, and sweat. Primarily triggered by light signals from your eye, the pacemaker figures out when it's morning and sends out chemical messages keeping the rest of the cells in your body on the same clock.

Lack of sleep implants 'false' memories in brain   Telegraph - July 22, 2014

Sleep deprived people are more likely to misremember events and hold 'false' memories of the past, scientists have discovered. It is a common complaint of couples that their partner sometimes appears to have a different recollection of past events than themselves, leading to arguments and recriminations. But it could be caused by a lack of sleep. Missing out on sleep makes people forgetful and can even implant ÔfalseŐ memories of events that have never taken place.




Sleep's memory role discovered   BBC - June 5, 2014

A connection between two brain cells -- It is well known that sleep plays an important role in memory and learning. But what actually happens inside the brain has been a source of considerable debate. Researchers at New York University School of Medicine and Peking University Shenzhen Graduate School trained mice in a new skill - walking on top of a rotating rod. They then looked inside the living brain with a microscope to see what happened when the animals were either sleeping or sleep deprived. Their study showed that sleeping mice formed significantly more new connections between neurons - they were learning more.

Sleep 'cleans' the brain of toxins   BBC - October 18, 2013

The brain uses sleep to wash away the waste toxins built up during a hard day's thinking, researchers have shown. The US team believe the "waste removal system" is one of the fundamental reasons for sleep. Their study, in the journal Science, showed brain cells shrink during sleep to open up the gaps between neurons and allow fluid to wash the brain clean. They also suggest that failing to clear away some toxic proteins may play a role in brain disorders. One big question for sleep researchers is why do animals sleep at all when it leaves them vulnerable to predators?




Insomniacs' brains lose focus, scans suggest   BBC - August 30, 2013

"Sleep is the best medicine," says the old proverb. But many adults don't benefit enough from sleep, with as many as 60 percent reporting sleep problems at least several nights a week. Approximately 40 million Americans suffer from sleep deprivation, and the consequences can be serious, including accidents while working or driving. Untreated long-term sleep problems can lead to heart disease, mood disorders, weight gain and shortened life spans.




Brain's 'Clock' Disrupted in Depressed People   Live Science - May 14, 2013
Disrupted sleep is so commonly a symptom of depression that some of the first things doctors look for in diagnosing depression are insomnia and excessive sleeping. Now, however, scientists have observed for the first time a dysfunctional body clock in the brains of people with depression. People with major depression, also known as clinical depression, show disrupted circadian rhythms across brain regions, according to a new study published today in the journal Proceedings of the National Academy of Sciences. Researchers looked at post-mortem brain samples from mentally healthy donors and compared them with those of people who had major depression at the time of their death. They found that gene activity in the brains of depressed people failed to follow healthy 24-hour cycles.




Bizarre Perpetual Sleepiness Explained   Live Science - November 26, 2012
A new treatment may help people with a bizarre medical condition that makes them perpetually sleepy. The findings may provide relief for the people who sleep constantly and feel exhausted despite caffeine, other stimulants, and several alarm clocks. People with hypersomnia need to sleep about 70 hours a week and have trouble rousing from sleep. When they are awake, they usually feel as if they've pulled an all-nighter, and describe it as walking around in a fog. Most people come to a diagnosis after conditions like depression, sleep apnea or thyroid problems have been ruled out.




Brain regions sleep more deeply when used more -- also in birds   PhysOrg - January 12, 2011

The research in Proceedings of the National Academy of Science showed a stress hormone causes the effect. A UK expert said it would be interesting to see if too little rather than no sleep had the same consequence.
