We’ve learned a lot about sleep this year. We know that getting more sleep can help you lose weight! We know that getting more sleep can improve or delay some symptoms of diabetes. Now we know that too little sleep can drastically reduce your cognitive abilities.
Those who believe they can function well on six or fewer hours of sleep every night may be accumulating a “sleep debt” that cuts into their normal cognitive abilities, according to research conducted at the University of Pennsylvania School of Medicine. What’s more, the research indicates, those people may be too sleep-deprived to know it.
The study, published in the March 15 issue of the journal Sleep, found that chronically sleep-deprived individuals reported feeling “only slightly sleepy” even when their performance was at its worst during standard psychological testing. The results provide scientific insight into the daily challenges that confront military personnel, residents and on-call doctors and surgeons, shift workers, parents of young children, and others who routinely get fewer than six hours of sleep each night.
“Routine nightly sleep for fewer than six hours results in cognitive performance deficits, even if we feel we have adapted to it,” said Hans P.A. Van Dongen, PhD, Assistant Professor of Sleep and Chronobiology in Penn’s Department of Psychiatry and corresponding author of the study. “This work demonstrates the importance of sleep as a necessity for health and well-being. Even relatively moderate sleep restriction, if it is sustained night after night, can seriously impair our neurobiological functioning.”
David F. Dinges, PhD, Professor of Psychology in the Department of Psychiatry and Chief of the Division of Sleep and Chronobiology, served as principal investigator for the study.
Dinges, Van Dongen and their colleagues looked at the effects of four hours nightly sleep and six more hours nightly sleep on healthy volunteer subjects aged 21 to 38, over a two-week period. They compared the results of the subjects’ accumulating performance deficits, determined by standard psychomotor vigilance and other cognitive tests, with similar test results obtained from subjects who had gone without sleep for more than three nights.
The first group of subjects experienced increasing lapses in psychomotor vigilance over days, resulting in a decline of performance that matched that of the subjects who went without sleep for 88 hours. At that level, the subjects suffered lapses in their ability to react that would put them at risk driving or flying an airplane. They were also less able to multi-task successfully.
“The physiologic expression of sleep in humans appears to have multiple functions, ranging from the metabolic to the neurocognitive,” Van Dongen said.
Other scientists who worked on the study are Greg Maislin, MS, MA, also of Penn, and Janet M. Mullington, PhD, of Beth Israel Deaconess Medical Center and Harvard University.
The study was funded by the National Institute of Nursing Research of the National Institutes of Health with additional financial assistance from the National Center for Research Resources and the National Heart, Lung and Blood Institute.
Covert Hypnosis: An Advanced Course in Subtle Unconscious Influence The Master’s Secrets Revealed! (Vol. 1 – 8)
“This is THE advanced course in subtle influence! Remember when you read Covert Hypnosis: An Operator’s Manual, and you got that WOW! feeling inside?! Well, that was just the beginning. In Covert Hypnosis: The Master’s Secret Revealed, you are going to learn how to subtly move inside the minds of anyone you communicate with. In trance or out…this is the most powerful material on Covert Hypnosis on the planet. Period.” Kevin Hogan, Psy.D.
In CD 1, Kevin Hogan reveals specifically the secrets of how to weave the exact messages you want others to act upon into stories that captivate listeners.
CDs 2 & 3 show you how to motivate and compel other people to change their behavior as quickly as is humanly possible. Benefit: You can utilize these covert tools with your own unconscious mind because they link into the core drives and desires that you have!
CD 4 reveals ALL 22 elements of Covert Hypnosis for this first time anywhere! Never before released by anyone, anywhere. The complete Covert Hypnosis Model for change is here. Business? Sales? Consulting? Coaching? Therapy? Learn specifically how to generate change in their thinking with the Covert Hypnosis Model.
CD 5 gives you all the tools necessary to take a person’s deepest drives (sex, eating, acquisition, connection, etc.) and fuse them into building compelling outcomes (the girl of your dreams, lose weight, acquire wealth, meet new people easily). Ignore either aspect, and failure is assured. Successfully meld the two in the unconscious mind and amazing things can happen.
CD 6—Pattern Recognition: Getting someone to think about something is one thing. Getting someone to feel driven to DO something and then watch them do it like magic is something else entirely. Learn so much in just this one CD!!!
CD 7 – This is 2003 neuroscience and research that reveals how to rewire the brain. Some neuroscientists call it “sculpting.” It’s not something that happens instantly and it requires the use of both hemispheres which can be pretty tricky if you don’t know what you are doing.
CD 8 – You are going to learn some unique techniques in the eighth volume of Covert Hypnosis. Not only are you going to learn the truth about values (when they are critical and when they are MEANINGLESS) but you are going to discover the values of the unconscious mind! The unconscious mind and conscious mind do not correlate to each other but they both correlate to the behavior of every person you meet.
Intrigued? Discover the secrets to what separates Covert Hypnosis from every other compliance technology Discover what even the experts don’t know about how the mind interacts with the unconscious mind.
