Brain-Changing Hammocks - The Sweet Pursuit - Utne Reader - 0 views

  • It’s summertime, and hammock season is here. Time to lay back, sway under a shade tree, let the breeze kiss the soles of your bare feet, and drift off. Certainly a hammock can help you relax, but new research suggests it can also alter brain activity to improve sleep. In a study published in the June 2011 issue of Current Biology, neuroscientists at the University of Geneva claim that gentle rocking makes people fall asleep faster and experience deeper sleep by synchronizing brain waves.
  • The researchers enlisted 12 men to take two afternoon naps in a quiet, dark room on a bed that could simulate the gentle rocking motion of a hammock. (Chances are, they didn't have a hard time rounding up volunteers.) For one nap, the bed rocked; for the other, the bed was stationary. Cynthia Graber of Scientific American reports the findings:
  • All the men fell asleep faster when they swayed. And the scientists monitored the men’s brain activity during all the naps. They found that rocking increased the duration of what’s called N2, a non-REM stage that accounts for about half of a good night’s sleep. Rocking also increased deep-sleep-associated brain activity—so-called slow oscillations as well as bursts of action called sleep spindles. Though the conclusions drawn from this naptime study are encouraging, the jury is still out on whether hammocks can alleviate insomnia at night. But, why wait for proven results? Put down the Ambien and try a hammock.

Diagnosing the Wrong Deficit - NYTimes.com - 0 views

  • Attention-deficit problems are far from the only reasons to take our lack of quality sleep seriously. Laboratory animals die when they are deprived of delta sleep. Chronic delta sleep deficits in humans are implicated in many diseases, including depression, heart disease, hypertension, obesity, chronic pain, diabetes and cancer, not to mention thousands of fatigue-related car accidents each year. Sleep disorders are so prevalent that every internist, pediatrician and psychiatrist should routinely screen for them. And we need far more research into this issue. Every year billions of dollars are poured into researching cancer, depression and heart disease, but how much money goes into sleep?

Sleep Loss Alters Genes While Raising Risk of Disease - Bloomberg - 0 views

  •  
    Just a week of inadequate sleep can alter the activity of hundreds of genes, which may help scientists explain how wakeful nights can lead to ailments such as diabetes, obesity and heart disease.

BBC News - The myth of the eight-hour sleep - 0 views

  •  
    "We often worry about lying awake in the middle of the night - but it could be good for you. A growing body of evidence from both science and history suggests that the eight-hour sleep may be unnatural."

HOW, AND WHEN, TO MAKE A DECISION | More Intelligent Life - 0 views

  • Seemingly trivial things have a huge influence on the way that we make decisions, research shows. Bill Ridgers reports ...
  • You have a big decision to make. Whether to put in an offer on a house, say, or change jobs. Which of the following will help you make the right choice: being in a state of sexual excitement or having a full bladder? Most likely, it is not something you have pondered. Psychologists, however, have long studied the ways that external factors such as these influence our decision-making. A full bladder, apparently, helps us take more rational, long-term decisions. At least that was the finding of a study carried out by Mirjam Tuk, a professor at the University of Twente in the Netherlands.
  • If true, Tuk’s findings are interesting because they challenge an established psychological theory called “ego depletion”. This states that we only have a finite well of self-control. Each time we deny ourselves something—whether going to the bathroom or choosing a salad for lunch, rather than the sausage sandwich we really wanted—we use up some of our reserves. The theory of ego depletion was developed by Roy Baumeister, a psychologist at Florida State University. In practical terms, he says, this means that if you have an important decision to make, you shouldn’t draw from your well of self-control beforehand. Reserves, he says, can be depleted in all sorts of ways: “Even things like trying to look interested at a boring meeting, trying to pretend your boss’s jokes are funny or not saying something unkind to your spouse when you are angry.”

  • Decision-making ability can be thought of as akin to a muscle, Baumeister says, in that it is liable to be worn out with overuse. For some, this effect can be life-changing.
  • The reason, Ackerman believes, is that touch is the first sense that we develop after birth. “People learn how to make decisions about the world by understanding what they’ve already experienced, and that means the physical world.” The ability to think in the abstract, of course, comes much later.
  • Another area of interest to the study of decision-making revolves around sleep deprivation. Professor Michael Chee, a neuroscientist at the National University of Singapore, says that most of us already realise that making decisions when we are exhausted is not advisable. Yet the effect that tiredness has on us is counter-intuitive. Chee says that we tend to believe that we become overly cautious in order to compensate. But the truth, he says, is that a lack of sleep makes us much too optimistic in our decision-making.
  • To return to the original question, being sexually aroused, alas, is not an aid to decision-making. Studies have shown that it can make us impetuous, much as you’d expect. But what is striking is that we greatly underestimate its effect. When Dan Ariely, a professor at Duke University in America, and author of “Predictably Irrational”, experimented on his undergraduates, he found that they had no idea of the extent to which they were being led by their libidos. One reason, Ariely believes, is that we have only a limited mix of emotion and cognition to draw upon. Increase one and you automatically detract from the other. So Robin Williams may have been making a valid psychological point when he said: “God gave men both a penis and a brain, but unfortunately not enough blood supply to run both at the same time.”
  • But if all our decisions are so influenced by external factors, that raises an inevitable question: to what extent are we involved in our own decision-making? Professor Ackerman believes the answer is very little: “All of these subtle influences suggest that most of what is causing our behaviour we are really not aware of. People are just very good at post-hoc reasons for their behaviour.”

Wall Street Protest Shows Power of Place - NYTimes.com - 0 views

  • no matter how instrumental new media have become in spreading protest these days, nothing replaces people taking to the streets.
  • In his “Politics,” Aristotle argued that the size of an ideal polis extended to the limits of a herald’s cry. He believed that the human voice was directly linked to civic order. A healthy citizenry in a proper city required face-to-face conversation.
  • We’re so distracted these days, people have forgotten how to focus. But the ‘mic check’ demands not just that we listen to other people’s opinions but that we really hear what they’re saying because we have to repeat their words exactly.

  • Living in Europe for the past few years, I often came across parks and squares, in Barcelona and Madrid, Athens and Milan, Paris and Rome, occupied by tent communities of protesters. Public protest and assembly are part of the European social compact. Maybe the difference in America has something to do with our longstanding obsessions with automobiles and autonomy, with our predilection for isolationism, or our preference just for watching, more than participating.
  • This peculiarity of zoning law has turned an unexpected spotlight on the bankruptcy of so much of what in the last couple of generations has passed for public space in America. Most of it is token gestures by developers in return for erecting bigger, taller buildings. Think of the atrium of the I.B.M. tower on Madison Avenue and countless other places like it: “public” spaces that are not really public at all but quasi-public, controlled by their landlords. Zuccotti in principle is subject to Brookfield’s rules prohibiting tarps, sleeping bags and the storage of personal property on the site. The whole situation illustrates just how far we have allowed the ancient civic ideal of public space to drift from an arena of public expression and public assembly (Speakers’ Corner in Hyde Park, say) to a commercial sop (the foyer of the Time Warner Center).
  • “It requires an architecture of consciousness,”
  • In Europe, the protests were about jobs, government rollbacks and debt. That the message of the Zuccotti Park occupiers is fuzzy somewhat misses the point. The encampment itself has become the point. “We come to get a sense of being part of a larger community,” said Brian Pickett, a 33-year-old adjunct professor of theater and speech at City University of New York. I found him sitting last week among the neat, tarpaulin-covered stacks of sleeping bags in one corner of the park. “It’s important to see this in the context of alienation today. We do Facebook alone. But people are not alone here.”
  • Imagine Zuccotti Park, one protester told me, as a Venn diagram of characters representing disparate political and economic disenchantments. The park is where their grievances overlap. It’s literally common ground.
  • And it was obvious to me watching the crowd coalesce over several days that consensus emerges urbanistically, meaning that the demonstrators, who have devised their own form of leaderless governance to keep the peace, find unity in community
  • The governing process they choose is itself a bedrock message of the protest.
  • That said, on the ground is where the protesters are building an architecture of consciousness.
