Sleep Step 1 | Step 2 | Step 3 | Step 4 | Step 5 | Step 6 Written by Kevin Morton with adaptations from the Stanford Sleep Book While sleep in the perspective of those experiencing it may seem more or less the same throughout the night, this couldn't be further from the truth.

Everyday Jet Lag - The New York Times

If you consider yourself to be a born morning person or an inveterate night owl, there is new research that supports your desire to wake up early or stay up late. Each of us has a personal “chronotype,” or unique circadian rhythm, says Till Roenneberg, a professor of chronobiology at Ludwig Maximilian University in Munich and one of the world’s experts on sleep. In broad strokes, these chronotypes are usually characterized as early, intermediate or late, corresponding to people who voluntarily go to bed and wake early, at a moderate hour or vampirishly late. If you are forced to wake up earlier than your body naturally would, you suffer from what Roenneberg calls “social jet lag.” People with an early chronotype may do well with a 7 a.m. workday rising time, but others do not.

Their chronotype may also have contributed to weight gain in the first place, Roenneberg says. Delayed Sleep Phase Syndrome - What It Is And How To Treat It. Written by Josh Stone with contributions from Kevin Morton, Spring 2010 It is a quiet Sunday night on Anyold University's campus, and Julian is just finishing up the last of his schoolwork for Monday.

Delayed Sleep Phase Syndrome - What It Is And How To Treat It

Knowing that he has a 9:00 am class the next day, he decides he is going to get in bed at 11:30. However, although Julian crawls into bed right on schedule, he finds that he is still completely alert and awake, and lies in bed all the way until 3:00 am before he ever actually falls asleep. The next morning, Julian awakes to his alarm at 7:30 having gotten less then five hours of sleep the night before. He groggily drags himself out of bed, not feeling the least bit refreshed.

Delayed Sleep Phase Syndrome - By Dr. William Dement

What is Delayed Sleep Phase Syndrome (DSPS)? It is a disorder in which the major sleep episode is delayed by 2 or more hours of the desired bedtime. This causes difficulty awakening at the desired time. Everything you ever wanted to know about SLEEP. Tuesday, November 5, 2013 Phillip Martin, artist/educator Well, everything I’ve already published on SLEEP here on, anyway —and that’s quite a lot(all linked below) Whether or not ADD-seasoning (aka brain-based attentional struggle) is any part of your neurodiversity mix, below are links to the published Sleep Series articles with NEED to KNOW INFO (only if you are planning to thrive, of course).

Everything you ever wanted to know about SLEEP

What science has discovered about sleep relatively recently is still under-reported in the mainstream media. Circadian Rhythm and Human Health. Joan E.

Circadian Rhythm and Human Health

Roberts Department of Natural Sciences, Room 813 Fordham University, 113 West 60th Street New York City, NY 10023 Introduction All life on earth evolved under both a light and dark cycle (Santillo et al., 2006; Musio and Santillo, 2009). As the sun rises and reaches its peak at noon, the spectrum it emits is smooth throughout the visible spectrum with a high intensity in the blue region [400 - 500 nm].

Humans evolved being exposed to different spectra of light in the morning, the late afternoon and evening. What is Circadian Rhythm? Circadian Rhythm is derived from the Latin words circa dies meaning "approximately a day". Light and Dark and Circadian Rhythm. JetLagged for Life. Please – take time to read the comments.

This Series is excerpted from a book I am writing about disordered sleep architecture. The content in a chapter of the section on some of the lesser known sleep disorders was written from personal experience, hoping to “put a face” on chronorhythm disorders, – disorders of sleep timing.

I hope that looking at life and living through the experience of a “coulda’ been a REAL contender” sufferer would describe things better than a list of symptoms and probable causes ever could. ~ mgh. 10.22.2007 - Sleep loss linked to psychiatric disorders. UC Berkeley Press Release Sleep loss linked to psychiatric disorders By Yasmin Anwar, Media Relations | 22 October 2007 BERKELEY – It has long been assumed that sleep deprivation can play havoc with our emotions.

This is notably apparent in soldiers in combat zones, medical residents and even new parents. Now there's a neurological basis for this theory, according to new research from the University of California, Berkeley, and Harvard Medical School. In the first neural investigation into what happens to the emotional brain without sleep, results from a brain imaging study suggest that while a good night's rest can regulate your mood and help you cope with the next day's emotional challenges, sleep deprivation does the opposite by excessively boosting the part of the brain most closely connected to depression, anxiety and other psychiatric disorders.

Sleep learning is possible: Associations formed when asleep remained intact when awake. Is sleep learning possible?

Sleep learning is possible: Associations formed when asleep remained intact when awake

A new Weizmann Institute study appearing August 26 in Nature Neuroscience has found that if certain odors are presented after tones during sleep, people will start sniffing when they hear the tones alone -- even when no odor is present -- both during sleep and, later, when awake. In other words, people can learn new information while they sleep, and this can unconsciously modify their waking behavior. Sleep-learning experiments are notoriously difficult to conduct.

For one thing, one must be sure that the subjects are actually asleep and stay that way during the "lessons. " The most rigorous trials of verbal sleep learning have failed to show any new knowledge taking root. Prof. In the experiments, the subjects slept in a special lab while their sleep state was continuously monitored. The next day, the now awake subjects again heard the tones alone -- with no accompanying odor. I Don't Dream? Yes You Do. Why We Have Nightmares & Forget Our Dreams. Joe Griffin explains why dreaming and forgetting our dreams, fulfils a vital human need.

I Don't Dream? Yes You Do. Why We Have Nightmares & Forget Our Dreams

THE human givens approach is a set of organising ideas that provides a holistic, scientific framework for understanding the way that individuals and society work. That framework has one central, highly empowering idea at its core — that human beings, like all organic beings, come into this world with a set of needs. If those needs are met appropriately, it is not possible to be mentally ill. I do not believe a more powerful statement than that could ever be made about the human condition. If human beings' needs are met, they won't get depressed; they cannot have psychosis; they cannot have manic depression; they cannot be in the grip of addictions.

Acronym Study hypothesis. Hypnagogia. "Waking dream" redirects here. It is not to be confused with daydreaming. Hypnagogia is the experience of the transitional state from wakefulness to sleep: the hypnagogic state of consciousness, during the onset of sleep. In opposition, hypnopompia denotes the onset of wakefulness. The related words from the Greek are agōgos "leading", "inducing", pompe "act of sending", and hypnos "sleep". Dreamland: Adventures in the Strange Science of Sleep - David K. Randall. Delayed sleep phase disorder. Delayed sleep-phase disorder (DSPD), also known as delayed sleep-phase syndrome (DSPS) or delayed sleep-phase type (DSPT), is a circadian rhythm sleep disorder affecting the timing of sleep, peak period of alertness, the core body temperature rhythm, hormonal and other daily rhythms, compared to the general population and relative to societal requirements.

People with DSPD generally fall asleep some hours after midnight and have difficulty waking up in the morning.[1] They probably have a circadian period a good deal longer than 24 hours.[2] Affected people often report that while they do not get to sleep until the early morning, they do fall asleep around the same time every day.
