When it comes to problem solving, getting enough sleep may truly be the secret to success.
Take the case of Kate Miller, the owner of Charlie's Playhouse, a maker of science education toys. Miller had been wrestling with a problem for weeks. But one morning the answer popped into her mind as she woke up. She wanted to design a game that would teach kids about natural selection while letting them run around and have fun.
A person with obsessive-compulsive disorder (or OCD) may experience:
Excessive and irrational concern about contamination or serious illness
Too much concern with keeping everything arranged in an exact way
Intrusive thoughts or horrible mental images
Sexual or religious thoughts felt to be unacceptable
Excessive fear of your house burning or flooding, of causing a car wreck, of spreading an illness, of losing something, of being responsible for another person getting hurt or killed
"It was the sleep that brought it all together," says Miller, 42, of Providence, R.I. "I ran downstairs, got a big pad of paper, and started sketching and writing."
Artists have long intuited a link between creativity and sleep, but scientists are beginning to nail down the connection. There's evidence that sleep, specifically the rapid-eye-movement (REM) stage associated with dreaming, helps organize and link together in novel ways the facts we know and the things we experience.
How Sleep Boosts Creativity
"Creativity is the ability to connect disparate ideas in new and useful ways," says Sara C. Mednick, PhD, assistant professor in the department of psychiatry at the University of California, San Diego. Her research indicates that REM sleep might enhance creative problem-solving by helping the brain associate seemingly unrelated ideas.
During the day, an area of the brain called the hippocampus takes in information and lets us hold it in our minds. It knows why you learned the information, Mednick says. For example, the hippocampus may learn that you need to turn at the red building to reach the doctor's office. During REM sleep, the hippocampus shuts down and allows the information it stored to move into the neocortex, the part of the brain that holds the sum of all of your experiences. Once a memory or experience reaches the neocortex, it can be associated with all the other memories.
And that's where creativity happens, Mednick says. The neocortex might match that shade of red on the building with the need to come up with the color for a toy, and voilà! Priming your brain to make these new connections seems to be key, research shows. An idea might seem to come out of nowhere, but in fact, it's the end of a process that may have begun days ago.
Miller says her crazy, beautiful, and totally new ideas come to her when she wakes up. "They always make me jump out of bed and run to write them down."
