Según un estudio realizado por Phillips basado en una muestra de 1.830 ciudadanos.
En la madrugada del sábado al domingo, a las 03:00 horas serán las 02:00.
El 23 % de los encuestados afirma que padece alteraciones en el sueño.
Los gallegos son los que peor llevan el cambio horario de invierno.
Uno de cada tres españoles asegura que el cambio horario de invierno le afecta negativamente y que sufre, como consecuencia, alteraciones en el sueño, cansancio y dificultades para levantarse por las mañanas, según un estudio realizado por la compañía Philips.
La madrugada del sábado al domingo, a las 03:00 horas, comienza el horario de invierno
La madrugada del sábado al domingo, a las 03:00 horas, comienza el horario de invierno y los relojes deberán atrasarse 60 minutos, es decir, serán las 02:00 horas.
El análisis, basado en una muestra de 1.830 ciudadanos de entre 18 y 55 años, revela además que cuatro de cada diez españoles lleva peor el cambio horario de invierno -que hace que amanezca más temprano y oscurezca antes- que el de verano, aunque sólo el 14 % considera que es "muy molesto" y que lo suprimiría.
Unas consecuencias que no dejan dormir
Entre las principales consecuencias, el 23 % afirma que padece alteraciones en el sueño, mientras que el 21 % y el 20 % de los encuestados declara, respectivamente, que se siente cansado y que le cuesta levantarse por las mañanas.
El 66 % considera que adaptar los relojes a las horas de luz es una medida efectiva para ahorrar energía
No obstante, el 66 % considera que adaptar los relojes a las horas de luz es una medida efectiva para ahorrar energía, y sólo algunas personas mayores dudan de la eficacia de esta medida.
Del total de la población española, los gallegos son los que peor llevan el cambio horario de invierno, ya que un 43 % considera que les afecta de forma negativa y un 30 % asegura que le resulta molesto y lo suprimirían.
Los gallegos también son los que dicen sufrir más alteraciones en el sueño, mientras que los castellano manchegos son los que se sienten más cansados (35 %), con una cifra que se sitúa muy por encima de la media nacional.
Por contra, los andaluces opinan que, en general, están "despiertos" por las mañanas, y los canarios y extremeños, que a pesar de los cambios horarios, tienen ganas de hacer cosas cuando se despiertan.
Los andaluces y los murcianos son además los menos escépticos respecto a los resultados de ahorro energético que conlleva esta medida.
Todo lo que ocurre en una hora
Nacimientos: Nacen 15.525 bebés en todo el mundo.
Muertes: 1.458 personas pierden la vida por desnutrición.
Bocadillos: Los españoles se comen 404.566,21 en una hora.
Relaciones sexuales: En el mundo se realizan 70.547.945 actos sexuales.
Bodas: Contraen matrimonio 23,8 parejas en nuestro país.
Divorcios: Se rompen oficialmente 17 uniones conyugales en España.
Sida: Se contagian de VIH 1,59 personas en el mundo.
Aviones: Aproximadamente despegan 25 aviones desde el aeropuerto de Barajas en Madrid.
¿De dónde nos viene la norma del cambio de hora?
El cambio de hora se convirtió en norma en 1974 -un año después de la primera crisis del petróleo- con el objetivo de aprovechar mejor la luz del Sol y consumir menos electricidad.
Adelantamos el reloj el último domingo de marzo y lo retrasamos el último de octubre
Esta medida se aplica como directiva europea desde 1981 y se renueva cada cuatro años.
Adelantamos el reloj una hora la madrugada del último domingo de marzo y lo retrasamos el último domingo de octubre.
En España, el cambio horario se realizó por primera vez, de manera no oficial, en 1918, para ahorrar carbón.

Robaron la casa de Lionel Messi en Barcelona
La nueva casa de Lionel Messi en Barcelona fue robada esta semana y los ladrones se llevaron varios objetos de valor, dijo este sábado el diario español "Sport" en su sitio de internet.
El periódico detalló que los delincuentes ingresaron en la noche del jueves o en la madrugada del viernes al hogar de Messi en Castelldefels, una zona residencial en la que viven otros integrantes del Barça. Según "Sport", Messi se encontraba muy afectado porque en el robo desaparecieron objetos de gran valor sentimental.
Apple ready to set Leopard free
Leopard comes in one flavour for all usersLeopard, the latest update of the Apple Mac operating system OS X, goes on sale on Friday.
The release ends months of waiting for Mac fans, after Apple pushed back the launch to finish development on its much-hyped iPhone.
Early reviews for Leopard have been positive with veteran technology writer Walt Mossberg calling it "evolutionary, not revolutionary".
Apple is hoping to build on recent strong sales of its Mac computers.
In the last three months, Apple sold 2.2 million Macs, up 400,000 on its previous best quarter.
The company is touting Leopard as a Vista-beater, pointing to new features not found in the new operating system (OS) from Microsoft that drives many PCs.
Apple says there are 300 new features in Leopard, but some of them are minor tweaks to the previous OS, called Tiger, rather than fully-fledged tools or enhancements.
Writing in the Wall Street Journal, Mossberg said: "I believe it builds on Apple's quality advantage over Windows.
"In my view, Leopard is better and faster than Vista, with a set of new features that make Macs even easier to use."

'Few disappointments'
In the New York Times, technology columnist David Pogue wrote: "Happy surprises, and very few disappointments, lie around every corner."
At the MacLiveExpo, being held in London, there was a mixed response from attendees on whether they would be rushing out to buy Leopard on day one.
Many of the delegates said they would wait for the operating system to "bed down" before they bought it.
"I never buy any operating system when it first comes out. I normally wait until it has been out for six months or a year," said David Ramage, a Mac user from Luton.
Vista has been quite a disappointment for many people and Leopard could be the reason many people make the switch to Macs
Nik Rawlinson, editor of MacUser magazine
He added: "Tiger does what I need it to do right now. I've not seen anything in Leopard to make me want to buy it immediately."
For developers, a new operating system means having to work to ensure their programs run smoothly on the new platform.
Ben Rudolph, director of communications at SWSoft, makers of Parallels, said Leopard was a big step forward for Apple and "would continue to drive sales of Macs".
Parallels lets users run Windows and Linux alongside OS X on a single Apple machine.
Mr Rudolph said Parallels would run smoothly under Leopard, barring any last minute changes to the code released by Apple.
"If that happens, we'll release a free, automatic update to account for them very soon after Leopard's launch," he said.
Of the new features in Leopard, Mr Rudolph said he was looking forward to being able to take advantage of his Mac's 64-bit architecture.
The new OS takes full advantage of the latest generation of chips inside Apple machines, while running applications on older processors also.
"I'm also looking forward to new user-experience features like Stacks, which should help me organise my incredibly messy desktop, and Spaces, which lets me cycle between different desktops."
Nik Rawlinson, editor of MacUser magazine, said many users would get Leopard in its first few weeks on sale.
"When Tiger was launched it earned Apple $120m very quickly and all the expectations are that sales will be double that."
He added: "Vista has been quite a disappointment for many people and Leopard could be the reason many people make the switch to Macs."
He said he felt Leopard had enough new features to distinguish itself from Microsoft's Vista.
"A lot of things that were previously only add-ons in the Mac world, such as the Apple TV interface, are now integrated into the OS.
"That is competing directly with Media Center on Windows PCs. Apple has seen that Microsoft has moved forward in some areas and is responding."

Neanderthals 'were flame-haired'
Some Neanderthals were probably redheads, a DNA study has shown. 
Writing in Science journal, a team of researchers extracted DNA from remains of two Neanderthals and retrieved part of an important gene called MC1R.
In modern people, a change - or mutation - in this gene causes red hair, but, until now, no one knew what hair colour our extinct relatives had.
By analysing a version of the gene in Neanderthals, scientists found that they also have sported fiery locks.
"We found a variant of MC1R in Neanderthals which is not present in modern humans, but which causes an effect on the hair similar to that seen in modern redheads," said lead author Carles Lalueza-Fox, assistant professor in genetics at the University of Barcelona.
Though once thought to have been our ancestors, the Neanderthals are now considered by many to be an evolutionary dead end.
They appear in the fossil record about 400,000 years ago and, at their peak, these squat, physically powerful hunters dominated a wide range spanning Britain and Iberia in the west, Israel in the south and Siberia in the east.
Our own species, Homo sapiens, evolved in Africa, and displaced the Neanderthals after entering Europe about 40,000 years ago. The last known evidence of Neanderthals comes from Gibraltar and is dated to between 28,000 and 24,000 years ago.

Altered chemistry
The latest research suggests that similar adaptations were evolved independently by Neanderthals and modern Europeans in response to similar environmental circumstances.
All humans carry the MC1R gene, but modern redheads possess an altered, or mutated, version of it.
This rare variant doesn't work as effectively as more common forms of the gene. This loss of function alters the chemistry of the cell, producing red hair and pale skin.
In the latest study, the authors retrieved fragments of the MC1R sequence from Neanderthal bones found at Monte Lessini in Italy and from remains unearthed at El Sidron cave in northern Spain. DNA is notoriously difficult to obtain from very old specimens such as these.
"This was a bit like finding a needle in a genomic haystack. I couldn't believe we found it the first time. I asked my friends to repeat the results. Eventually the variant was found in two separate Neanderthals in three different labs," said Dr Lalueza-Fox.

Unique variant
The researchers found that Neanderthals carried a unique variant of the gene not present in modern humans.

n order to test what effect it had on hair and skin colour, the researchers inserted the Neanderthal variant into a human cell called a melanocyte.
Melanocytes produce the dark pigment called melanin which gives skin, hair and eyes their colour.
The researchers saw the same loss of function in the Neanderthal form of MC1R as they did in modern variants of the gene which produce red hair.
"In Neanderthals, there was probably the whole range of hair colour we see today in modern European populations, from dark to blond right through to red," Dr Lalueza-Fox told the BBC News website.
To Dr Lalueza-Fox, the observation that the Neanderthal version of the gene is not found in modern humans suggests they did not interbreed with each other, as some scientists have proposed.

Facebook: Un Hi5 gigante??
¿Facebook?. Si este nombre no suena familiar, pues debería, ya que se trata de una de las 20 páginas de internet más visitadas del mundo, con 47 millones de “adictos” y que permite al usuario crear su propia web y comunicarse con otros usuarios de la comunidad. Cada día se suman a él 200 mil nuevos usuarios. Nada menos.
Este es el sitio de redes sociales más visto después de MySpace y que acaba de convertirse en una de las firmas con más valor de la web, luego que el miércoles Microsoft anunciara que adquirirá una participación de 1,6 por ciento en el capital de Facebook por 240 millones de dólares.
La oferta de Microsoft se impuso a otra del buscador de Internet Google, que también negociaba para comprar una parte del sitio de redes sociales.
La oferta de Microsoft se impuso a otra del buscador de Internet Google, que también negociaba para comprar una parte del sitio de redes sociales.
El dueño tiene 23 años
La oferta valora Facebook en unos 15.000 millones de dólares, nada mal para una empresa fundada en 2004 por un estudiante que hoy tiene 23 años, Mark Zuckerberg, y que prevé que los beneficios de 2007 no superen los 100 millones de dólares.
Zuckerberg es un muchacho de apariencia tímida siempre calzado con unas sandalias Adidas de los 80 -el equivalente al jersey de negro de Steve Jobs, presidente de Apple- que se ha convertido en el "niño bonito" de Silicon Valley.
Apertura
El fundador de Facebook ha señalado en varias ocasiones que quiere mantener la independencia de la firma y que, algún día, la sacará a bolsa, aunque no antes de dos años.
Según los analistas, Zuckerberg tomó dos decisiones acertadas que permitieron a su servicio distanciarse de otros tantos sitios similares de Internet.
La primera fue abrir la página a todos los usuarios de la red, ya que un principio estaba limitada al ámbito universitario.
Miles de aplicaciones
La segunda fue permitir a programadores ajenos a la empresa que diseñaran aplicaciones que los usuarios pudieran añadir a su perfil y que se quedaran con los ingresos publicitarios generados por ellas.
Ya se han creado miles de aplicaciones que van desde lo loable - sistemas de recaudación de fondos para causas humanitarias- hasta lo absurdo, como un programa para enviar mordiscos virtuales a otros usuarios y convertirlos en zombies.

Hoy Facebook es una de las 20 páginas más visitadas de Internet y el primer sitio de redes sociales después de MySpace, propiedad del magnate de los medios de comunicación Rupert Murdoch.
En el sector tecnológico hay opiniones de todos los gustos sobre el éxito de Facebook y la millonaria oferta de Microsoft.

Publicidad
Para algunos, Facebook es la gallina de los huevos de oro por los enormes ingresos publicitarios que semejante número de usuarios puede generar.
Para otros, una oferta de esas características sobrevalora la compañía porque los usuarios suelen ignorar la publicidad que aparece en Facebook y los anuncios no están relacionados con los intereses y datos demográficos de la persona que los ve.
No compite con Google
Rishard Tobaccowala, director de la división de medios del grupo publicitario Publicis, insiste en que Facebook no es el nuevo Google, una firma con la que se la compara a menudo.
"Facebook sólo tiene enormes grupos de personas comunicando sin expresar intereses específicos", dijo Tobaccowala a la revista The Economist antes de hacerse pública la operación de Microsoft.
En Google, sin embargo, el anunciante conoce los intereses del usuario, que se convierte así en un cliente potencial y, además, la publicidad es valorada por los internautas porque está relacionada con los términos que buscan, añadió.
