A painting of a young woman taking a siesta. ( The hammock, (1844).) A siesta ( Spanish pronunciation: ) (Spanish, meaning 'nap') is a short taken in the early afternoon, often after the midday. Such a period of is a common tradition in some countries, particularly those where the weather is warm. The siesta is historically common throughout the and.

It is the traditional daytime sleep of and, through Spanish influence, the, and many countries. The word siesta of the derives originally from the word hora sexta 'sixth hour' (counting from dawn, hence 'midday rest'). Siesta is also common in (there called riposo, pisolino), where museums, churches and shops close during midday so that proprietors can go home for a long lunch and perhaps a snooze during the day’s hottest hours. 's describes the emperor's summertime siestas: 'In summer, after his midday meal, he would eat some fruit and take another drink; then he would remove his shoes and undress completely, just as he did at night, and rest for two or three hours.' Factors explaining the geographical distribution of the modern siesta are high temperatures and heavy intake of food at the midday meal. Combined, these two factors contribute to the feeling of. In many countries that practice the siesta, the heat can be unbearable in the early afternoon, making a midday break at home welcome.

However, siesta is also practiced in some colder regions, such as. It used to be the custom in Russia, with stating such was 'the custom of the Countrey, where sleep is as necessary after as in the Night'. One source of hostility toward was that he did not '.indulge in the siesta.' : 535 This may indicate that the siesta has a stronger relation with culture than with climate. Contents • • • • • • • Biological need for naps [ ] The timing of sleep in humans depends upon a balance between sleep propensity, the need for sleep as a function of the amount of time elapsed since the last adequate sleep episode, and which determine the ideal timing of a correctly structured and restorative sleep episode. The homeostatic pressure to sleep starts growing upon awakening.

The circadian signal for wakefulness starts building in the (late) afternoon. As Harvard professor of Charles A. Czeisler notes, 'The circadian system is set up in a beautiful way to override the homeostatic drive for sleep.' Thus, in many people, there is a dip when the drive for sleep has been building for hours and the drive for wakefulness has not yet started. This is, again quoting Czeisler, 'a great time for a nap'. The drive for wakefulness intensifies through the evening, making it difficult to get to sleep 2–3 hours before one's usual bedtime when the ends. Sleep cultures [ ].

And sharing similar business hours in the island of,. Taking a long lunch break including a nap is common in a number of Mediterranean, tropical, and subtropical countries.

The of 13 February 2007 reports at length on studies in that indicate that those who nap have less risk of heart attack. In the United States, the, and a growing number of other countries, a short sleep has been referred to as a ', a term coined by social psychologist and recognized by other research scientists such as as well as in the popular press. On farms in rural Norway, farmers traditionally wake up early to care for their livestock. This is followed by an early dinner after which a two to three hour nap is taken. Spain [ ] In modern Spain, the midday nap during the working week largely has been abandoned among adult working population.

According to a 2009 survey, 16.2 percent of Spaniards polled claimed to take a nap 'daily', whereas 22 percent did so 'sometimes', 3.2 percent 'weekends only' and the remainder, 58.6 percent, 'never'. The share of those who claimed to have a nap daily had diminished by 7 percent compared to a previous poll in 1998. Nearly three-fourths of those who take siesta claimed to do so on the sofa rather than on the bed. The habit is more likely among the elderly or during summer holidays in order to avoid the high temperatures of the day and extend social life till the cooler late evenings and nights. English language media often conflate the siesta with the two to three hour which is characteristic of Spanish working hours, even though the working population is less likely to have time for a siesta and the two events are not necessarily connected. In fact, the average Spaniard works longer hours than almost all their European counterparts (typically 11-hour days, from 9am to 8pm). As for the origins of the practice in Spain, the scorching summer heat is thought to have motivated those doing agrarian work to take a break to avoid the hottest part of the day.

In cities, the dismal economic situation in Spain in the post- years coincided with the advent of both a modern economy and. At that time, a long midday break—with or without siesta—was necessary for those commuting between the part-time jobs which were common in the sputtering economy, at a time when both private and public transport were virtually non-existent. [ ] Cardiovascular benefits [ ]. La Siesta, (). The siesta habit has been associated with a 37 percent reduction in coronary mortality, possibly due to reduced cardiovascular stress mediated by daytime sleep. Epidemiological studies on the relations between cardiovascular health and siesta have led to conflicting conclusions, possibly because of poor control of confounding variables, such as physical activity. It is possible that people who take a siesta have different physical activity habits, for example, waking earlier and scheduling more activity during the morning.

Such differences in physical activity may lead to different 24-hour profiles in cardiovascular function. Even if such effects of physical activity can be discounted in explaining the relationship between siesta and cardiovascular health, it is still not known whether the daytime nap itself, a supine posture, or the expectancy of a nap is the most important factor.
