Alternative Sleep Cycles: 7-10 Hours Are Not Needed. The average person requires 7-10 hours of sleep per night according to the National Sleep Foundation. But is it possible that using different sleep cycles, where the benefits of sleep are still achieved, we can sleep less? Much less? Most of us are familiar with what is called a monophasic sleep cycle.

This cycle is used by most people as it’s what we hear about and learn the most. For some, this cycle is practical although inefficient. Fact is, there are 4 other sleep cycles that can provide all the benefits of sleep, while sleeping much less. For me, this is good news as I am not a huge fan of sleeping for long periods of time. Not only that but sleeping has always been something I wish I could do when I felt like it and not because I’m ‘supposed to.’ if I could spend less time lying awake at night trying to sleep, then great. The Monophasic cycle consists of various stages of sleep with REM (rapid eye movement) being the most important. How will you sleep? Source:Collective Evolution. Food waste reduction could help feed world's starving. 2 July 2014Last updated at 19:02 ET By Caroline Hepker BBC World Business Report One third of all food produced is wasted, the UN estimates "If food was as expensive as a Ferrari, we would polish it and look after it.

" Instead, we waste staggering amounts. So says Professor Per Pinstrup-Andersen, head of an independent panel of experts advising the UN's Food and Agricultural Organization on how to tackle the problem. Some 40% of all the food produced in the United States is never eaten. And yet there are one billion starving people in the world. The FAO's best guess is that one third of all food produced for human consumption is lost or wasted before it is eaten.

You have exactly the same number of hours per day that were given to Helen Keller, Pasteur, Michaelangelo, Mother Teresa, Leonardo da Vinci, Thomas Jefferson, and Albert Einstein.” ― H.

Jackson Brown Jr. A lot of folks in our society try to be hyper-productive. You know — the people who scurry from task to task, always checking e-mail, organizing something, making a call, running an errand, etc. The people who do this often subscribe to the idea that “staying busy” means you’re working hard and are going to be more successful. While this belief may be true to an extent, it often leads to mindless “productivity” — a constant need to do something and a tendency to waste time on menial tasks. Instead of behaving in this way, I choose to do things differently.

Educazione e Videogiochi: quale futuro? | Games Princess. All’interno del processo educativo, i videogiochi si sono inseriti con prepotenza ormai da diversi anni.

Come sappiamo, i videogiochi implicano una tendenza alla simulazione, caratteristica che consente di interpretare e ricostruire modelli dinamici virtuali dei fatti del mondo reale. La simulazione è divenuta un potente strumento di conoscenza ed apprendimento, grazie alla possibilità data dalle tecnologie digitali di ricostruire scenari anche molto complessi. Citando il famoso saggista statunitense Jenkins, i videogiochi offrono nuovi e potenti modi per rappresentare e manipolare informazioni.

Essi ampliano le nostre capacità cognitive e permettono di sperimentare configurazioni complesse di dati, testandole in tempo reale con diverse variabili. I videogiochi permettono di applicare il learning by doing, sostituendolo in molti casi al puro apprendimento nozionistico. LEGGI ANCHE: Imparare l’inglese con The Sims.

In the center is your brain on drugs. Then, on the right, is your brain on sugar. Notice the similarities between the middle and right images? The normal brain has a lot more red stuff highlighted in it — called Dopamine. This chemical is produced in the part of the brain that is associated with reward. Let's take another look: Image: Wikimedia Commons This PET brain scans show chemical differences in the brain between addicts and non-addicts. This is what sugar does to your brain — the exact same thing smoking, alcohol and cocaine do. Just how bad is America's addiction to sugar? The Centers for Disease Control project a double- or triple-fold increase in the proportions of Americans with diabetes by 2050.

In 2013, student-faculty research at Connecticut College found that in lab rats, Oreos, rich in sugar and fat, may be just as addictive as cocaine. So basically, Oreos are legal crack. Given all this, it's pretty likely you're over-consuming. Here's What Facebook Is Doing to Your Brain. The Trouble with Snooze Buttons (and with Modern Sleep) On a typical workday morning, if you’re like most people, you don’t wake up naturally. Instead, the ring of an alarm clock probably jerks you out of sleep. Depending on when you went to bed, what day of the week it is, and how deeply you were sleeping, you may not understand where you are, or why there’s an infernal chiming sound. Then you throw out your arm and hit the snooze button, silencing the noise for at least a few moments. Just another couple of minutes, you think. Then maybe a few minutes more. It may seem like you’re giving yourself a few extra minutes to collect your thoughts. One of the consequences of waking up suddenly, and too early, is a phenomenon called sleep inertia.

In those early waking minutes, our memory, reaction time, ability to perform basic mathematical tasks, and alertness and attention all suffer. Other research has found that sleep inertia can last two hours or longer. Fortunately, the effects of sleep inertia and social jetlag seem to be reversible.
