Naps with Dreams Improve Performance

July 13th, 2009

Have to solve a problem? Try taking a nap. But it has to be the right kind of nap — one that includes rapid eye movement, or REM, sleep, the kind that includes dreams.

……….lucid-dream-nap.

Researchers led by Sara C. Mednick, an assistant professor of psychiatry at the University of California, San Diego, gave 77 volunteers tests under three before- and-after conditions: spending a day without a nap, napping without REM sleep, and napping with REM sleep. Just spending the day away from the problem improved performance; people whostayed awake did a little better on the 5 p.m. session than they had done on the 9 a.m. test. Taking a nap without REM sleep also led to slightly better results. But a nap that included REM sleep resulted in nearly a 40 percent improvement over the pre-nap performance.
