    Sleep & Creativity

    Study: Sleep Essential For Creativity
    January 21, 2004

    NEW YORK (AP) -- For the first time, scientists say they have proved what creative minds have known all along: that our sleeping brains continue working on problems that baffle us during the day, and that the right answer may come more easily after eight hours of rest.

    The German study is considered to be the first hard evidence supporting the commonsense notion that creativity and problem-solving appear to be directly linked to adequate sleep.

    Some researchers said the study provides a valuable reminder for overtired workers and students that sleep is often the best medicine...

    Sleep has long been thought to improve creativity. Rolling Stones guitarist Keith Richards said the riff in "(I Can't Get No) Satisfaction" came to him in his sleep, while the 19th-century chemist Dmitri Mendeleev literally dreamed up the periodic table of elements.

    Scientists at the University of Luebeck found that volunteers taking a simple math test were three times more likely than sleep-deprived participants to figure out a hidden rule for converting the numbers into the right answer if they had eight hours of sleep. The findings appear in Thursday's issue of the journal Nature.

    Jan Born, who led the study, said the results support biochemical studies of the brain that indicate memories are restructured before they are stored. Creativity also appears to be enhanced in the process, he said.

    "This restructuring might be occurring in such a way that the problem is easier to solve," Born said.

    Born said the exact process in the sleeping brain for sharpening these abilities remains unclear. But it appears that memories start deep in an area of the brain called the hippocampus, and are eventually pushed outward to the neocortex to be consolidated.

    The changes leading to creativity or problem-solving insight occur during "slow wave" or deep sleep, which typically occurs in the first four hours of the sleep cycle, he said.

    The findings also may explain the memory problems associated with aging, because older people typically have trouble getting enough sleep, especially the kind of deep sleep needed to process memories, Born said.

    History is rife with examples of artists and scientists who have awakened to make their most notable contributions. Samuel Taylor Coleridge wrote the epic poem "Kubla Khan" after a long night of rest. Robert Louis Stevenson credited a good night's sleep with helping him create scenes in "The Strange Case of Dr. Jekyll and Mr. Hyde." And Elias Howe came up with his idea for the sewing machine after waking up....

    Some 70 million Americans are believed to be sleep-deprived, contributing to accidents, health problems and lower test scores. Maquet and Ruby said the study should be considered a warning to schools, employers and government agencies that sleep makes a huge difference in mental performance. The results "give us good reason to fully respect our periods of sleep -- especially given the current trend to recklessly curtail them," they said.

    Sleep & Creativity

    Now that's just "normal" everyday people, correct?

    I've read reports on how sleep deprivation actually helps manic depressives and those suffering from dysthymia. But then I've also read a lot on bi-polar and the creative mind.

    There's so many different reports/articles on the subject. Recently I read that people are terribly dehyrdated which has a huge affect on depression and even sleep patterns. The brain doesn't function properly due to the lack of water.... I wish I could find that article now....

    Sleep & Creativity

    I was listening to a medical program on the radio in my car last week and the doctor mentioned that the number one cause of day-time sleepiness and lack of energy was insufficient water intake. And he pointed out that coffee, tea, soft drinks, and alcohol may contain some water but do not count towards water intake (primarily because they are diuretics so you lose as much as you gain)...

    Re: Sleep & Creativity

    I believe there's a definite connection there. I often forget to drink sufficient water, and with my caffeine intake, I begin to "feel" the bags under my eyes, which I have been told are related to dehydration. At those times, I also notice it is difficult to focus and to think things through clearly. I almost never sleep well at those times. The last four or five days have been worse than usual in this regard. I've begun filling up an old Gatorade bottle with tap water, and keeping it by my desk at all times, so as to have a steady intake of water. I bet this will help.

    Re: Sleep & Creativity

    Well, yesterday I only had one cup of coffee, that being my morning cup. I actually slept close to eight hours last night. Today, however, I had an inclination to have a second cup after dinner. But I think I'll turn in shortly, and probably sleep well. I do notice that my general mode lately has been oddly disregarding of self-care; that is, not exercising & not drinking sufficient fluids other than those caffeinated. Certainly that lapse has contributed to the recent experiences of anxiety and of insufficient, erratic sleep.
