Spanish Word for Nap
The Spanish word "siesta" means nap in English.
There are two periods of siesta in Spain - the siesta for businesses and shops, during which time many people go to a bar or restaurant, and the siesta for restaurants, who obviously do not have the opportunity to rest when everyone wants to visit and eat.
The siesta for businesses and shops is from approximately 2pm until 5pm, and bars and restaurants close from approximately 4pm until approximately 8pm or 9pm.
The traditional reason for the siesta was that Spain is a hot country, especially mid-afternoon, and the siesta was for the workers in the fields to shelter from the heat. They would then feel refreshed after their sleep and would work until late in the evening when the temperature was much cooler.
The modern interpretation of a siesta is that Spanish like to have a long lunch. At home, mother will cook a huge lunch for the entire family which could last up to two hours. The rest before going back to work is essential after that.
The Spanish nightlife is an all night affair. This would not be able to happen if they had to do without a siesta.
