Det fungerar att sova på ett problem
Nature-artikeln Sleep boosts lateral thinking vet att berätta att det ligger mycket i påståendet att man ska sova på ett problem.
"Sleep on it" is standard advice to anyone agonizing over a tricky puzzle. A study of mathematical problem-solving has now shown that a good night's rest really does give you a fresh perspective.
The discovery lends credence to the popular maxim that sleep stimulates lateral thinking, says Jan Born of the University of Lübeck, Germany, who led the project.

Born and his colleagues presented subjects with a series of numbers. They gave participants a simple rule with which to generate a second string of numbers from the first, and asked them to deduce the final digit in this sequence. However, they didn't tell them about a hidden shortcut that allowed the final digit to be calculated almost immediately.
Artikeln avslutas med lite sömntips:
A 30-minute 'power nap' would be enough to give workers the benefits of REM sleep, says Ribeiro. Such an allowance could combat stress and boost workplace performance.
"You would expect a power nap to help you be more creative," agrees Born. "But as long as you get around eight hours' sleep at night you should be fine."
(För övrigt har Mats Andersson skrivit om sina erfarenheter av detta.)
