Siesta endures as a smart choice, according to new research at UC Berkeley

Spaniards and Latin Americans have known it for generations, but new research out of UC Berkeley shows once again that taking a midday nap revitalizes your brain and boosts its ability to absorb new information.

The study examined two groups -- nap and non-nap -- as they attempted learning exercises targeted at the brain’s hippocampus, where fact-based memories are stored. The napping group did markedly better, the study found.

‘Sleep is sophisticated,’ said Berkeley psychology professor Matthew Walker, who presented his study’s findings at a scientific conference on Sunday in San Diego. ‘It acts locally to give us what we need.’

No need convincing Ibero-Americans on the subject. According to the website SiestaAwareness.org, the siesta has origins in Islamic Law, but the word is Spanish, rooted in the Latin for ‘sixth hour,’ as in the sixth hour from dawn -- noon. In Spain, siestas are traditionally two hours.

While the tradition may not be as prevalent as before, or as commonplace in busy urban centers, afternoon naps are still seen as customary in many parts of Spain and Latin America.

In Mexico, hammocks are especially popular in coastal regions, where warm temperatures and the lull of the ocean make for an ideal setting for a nap.
