Sorry to say, a nap or two won’t make you smart or assure success. But doctors know that a good night’s sleep is associated with good health, and a 2007 Greek investigation linked napping with a reduced risk of heart disease. Now four studies suggest that naps may boost intellectual performance, at least in the short term. The research shows that NREM sleep can improve memory and that REM sleep can enhance creative problem solving. It’s a two-step approach that should give every man something to sleep on.
The subjects in the studies mentioned were men, but I see no reason why it shouldn’t apply to women too.
