Albert Einstein and Winston Churchill were both enthusiastic practitioners of the siesta, that short, restorative nap that allowed Einstein to solve complex scientific problems and Churchill to design complex political strategies into the small hours. The Spanish version of the cat-napper is rather less sophisticated and perhaps best illustrated by the writer Camilo Jose Cela. His admission, "I always take my siesta in pyjamas, with an Our Father and a potty" shows just what a serious business the siesta is. This ritual of resting for about half an hour after eating has a great tradition in Spain and, in recent years, it even comes with the doctors' blessing as research has shown it is a healthy habit. Restaurants and hotels also appreciate the benefits of the siesta, particularly in warmer places such as Seville. Here, the Association of Hoteliers of the province is promoting the habit through the hire of rooms where you can rest up after a large meal. No need to go home to nap, just book a room and take a break from your busy sightseeing schedule: you'll find it helps you get the most out of your day.
