Happy napping: A 45-minute nap helps you to retain information you have learned and 'significantly' improves recall, scientists said – meaning naps really could help students revising for exams
 
A power nap of just 45 minutes can boost memory by five times, research has found.
 
A short doze helps you to retain information you have learned and 'significantly' improves recall, scientists said – meaning naps really could help students revising for exams.
 
Participants in the study learned 90 single words and 120 unconnected word pairs such as 'milk taxi'.
 
Some then watched a DVD while others slept.
 
When they were then retested, those who had slept remembered more word pairs, the journal Neurobiology of Learning and Memory reports.

The scientists, from Saarland University in Germany, said that during sleep, bursts of brain activity known as sleep spindles play an important role in consolidating newly learned information.
 
Professor Axel Mecklinger said a nap of just 45 minutes to an hour 'produces a five-fold improvement in information retrieval from memory'
 
'The memory performance of the participants who had a power nap was just as good as it was before sleeping, that is, immediately after completing the learning phase.
 
'Strictly speaking, memory performance did not improve in the nap group relative to the levels measured immediately after the learning phase, but they did remain constant.'
 
'A short nap at the office or in school is enough to significantly improve learning success. Wherever people are in a learning environment, we should think seriously about the positive effects of sleep,' says Axel Mecklinger.
 
'Enhancing information recall through sleeping doesn't require us to stuff bulky tomes under our pillow.
 
'A concentrated period of learning followed by a short relaxing sleep is all that's needed.'

Not that Timon’s wealth all went to nike roshe run enrich these wicked flatterers; he supra shoes could do noble and praiseworthy actions; and when a servant of his longchamp handbags once mcm handbags loved uggs canada the daughter of a rich Athenian, but could not hope to christian louboutin shoes obtain her by reason that in wealth and rank nike trainers the maid was christian louboutin outlet so far above him, Lord Timon freely bestowed cheap ugg boots outlet upon his servant three Athenian talents, to make his fortune equal with the dowry which the father of air max pas cher the young maid demanded mac cosmetics of him who should be michael kors her husband. But for the most gucci part, vans pas cher knaves and parasites had the command of his fortune, ugg outlet false converse pas cher friends whom he pandora jewelry did not ray ban sunglasses know north face jackets to be such, but, because they flocked tory burch outlet online around his person, he thought they must needs love him; and because they smiled and flattered cheap oakley sunglasses him, he thought nike air force surely that his conduct was approved by ugg boots all nike outlet the nike free pas cher wise and good. And when he was feasting in the midst of all these flatterers and mock friends, when they were soccer shoes eating him up, and giuseppe zanotti draining his fortunes dry with large draughts of hollister clothing store richest wines michael kors outlet online drunk to his longchamp pas cher health and prosperity, ghd he could not perceive the difference of a friend from christian louboutin a coach outlet flatterer, longchamp but to his louboutin deluded michael kors uk eyes (made proud with the sight) it seemed a precious tiffany jewelry comfort ralph lauren pas cher to ray ban pas cher have so red bottom shoes many like brothers commanding hollister one another’s fortunes michael kors handbags (though it was his own fortune which paid all the costs), and with joy they reebok shoes would run over at the spectacle of such, as it ralph lauren appeared coach outlet to oakley vault him, montre femme truly replica watches festive and fraternal meeting.

But while he thus outwent bottega veneta the very links of london uk heart of kindness, and poured out his coach outlet bounty, as if Plutus, the true religion god of gold, toms outlet had replica watches been but his steward; while thus he true religion outlet proceeded without care or stop, kate spade outlet so senseless ray ban outlet of expense polo ralph lauren that he ralph lauren uk would neither inquire how he could maintain it, lululemon outlet online nor cease his wild flow of riot; his riches, which were not infinite, must needs melt away before nike air max a prodigality which knew gucci handbags no limits. But who should tell babyliss him true religion outlet so? his flatterers? they had an interest in shutting his eyes. In vain ugg did wedding dress his honest steward Flavius try to represent to him his michael kors outlet condition, laying his accounts before him, begging of ugg him, praying of him, nike air max with an importunity that on oakley sunglasses any other occasion would have been unmannerly in a servant, beseeching him with tears to look valentino shoes into sac lancel the state of his affairs. Timon would still put him off, and turn the chanel handbags discourse nike blazer pas cher to something longchamp else; for nothing is so deaf to remonstrance beats headphones as riches burberry outlet online turned to michael kors outlet online poverty, nothing converse is so unwilling to believe its situation, nothing so wedding dresses incredulous to its guess pas cher own true state, and hard to give credit to a reverse.

Often had this good steward, this honest creature, when all pandora uk the rooms timberland pas cher of Timon’s nike roshe great house have been choked up with riotous feeders at kate spade outlet online his master’s p90x workout cost, ferragamo shoes when the instyler ionic styler floors have wept with drunken vans outlet spilling of wine, and lululemon outlet every apartment has blazed with lights and resounded with music and feasting, chi flat iron often had he air max retired by himself iphone case to some solitary spot, and wept faster than the wine ran new balance outlet from the birkin bag wasteful casks within, to see the mad bounty of his michael kors outlet store lord, and to think, when the ugg australia means were gone which brought him praises from all longchamp outlet online sorts of people, how abercrombie quickly the breath would be gone of which the praise hollister canada was made; praises won in insanity workout feasting would juicy couture outlet be lost in fasting, and at one cloud of winter-showers these flies would disappear.

But now the time north face was come mont blanc pens that Timon could shut his ears no longer to the representations of this juicy couture faithful steward. Money must thomas sabo uk be had; and when he ordered Flavius to scarpe hogan sell nike air huarache some of his land for michael kors outlet online sale that purpose, Flavius nike roshe informed north face jackets him, what he had in swarovski uk vain endeavoured at several pandora charms times before louboutin to make him listen to, that most of his land michael kors canada was already sold jordan shoes or forfeited, and that all he true religion jeans possessed at present coach outlet store online was not enough to tiffany and co pay the one half of what he air jordan owed. Struck with wonder cheap ugg boots at this presentation, Timon hermes pas cher hastily replied, “My lands extend hollister uk from Athens to Lacedaemon.” coach purses “O my swarovski jewelry good lord,” said Flavius, “the world is but ugg boots clearance a world, and karen millen has bounds; baseball bats were it tn pas cher all yours new balance pas cher to give in a oakley breath, how quickly nike air max were it gone!”

Timon consoled himself that no villanous bounty had yet prada handbags come from him, that if sac vanessa bruno he had given soccer jerseys his wealth away unwisely, it had not been bestowed to feed his vices, but to cherish his friends; and mulberry uk he hollister bade the kind-hearted steward (who nike free was weeping) to take ray ban uk comfort in polo ralph lauren outlet the assurance that his longchamp outlet master could never lack means, nike air max while he had so many noble friends; and this infatuated lord persuaded himself that nike air max he had nothing to do but to send herve leger and borrow, asics shoes to jimmy choo shoes use every man’s fortune (that had ever ugg soldes tasted his vans bounty) in this nike free extremity, abercrombie and fitch as celine handbags freely as his own. Then with ray ban a cheerful look, as if confident of the trial, he severally despatched messengers to Lord Lucius, to Lords Lucullus and Sempronius, men upon whom he had lavished his gifts in past times without measure north face pas cher or moderation; and to Ventidius, whom he had lately marc jacobs handbags released out of converse shoes prison by paying his burberry outlet online debts, and nfl jerseys who, by the death of his father, was now come into the possession of an ample fortune, and well enabled to requite Timon’s courtesy: to request air max of Ventidius the return of those five talents which he had paid lacoste pas cher for him, and of each burberry pas cher of those noble lords timberland boots the loan of fifty talents; nothing oakley pas cher doubting that their gratitude would supply his wants (if he prada outlet needed it) to the amount of abercrombie and fitch five hundred times fifty talents.
