If Sitting Is the New Smoking, How Do We Kick the Habit? | Lance Henderson - 5 views

  •  
    "In the 2008 animated film WALL-E, Pixar depicted a light-hearted but dystopian world of obese, immobile people whose needs are met by a bustling horde of robots and computers -- a world that hardly seems like science fiction as we witness the precipitous decline in physical activity over the last generation. The Centers for Disease Control and Prevention estimates that approximately 80 percent of Americans don't get the recommended amount of exercise they need each week for optimal health. So, did Pixar predict the future of humanity or is there a way for us to course correct?

    Sedentary behavior is an intractable issue. Seemingly benign forces make it easier and easier for many of us to conduct our work, school and social lives from the comfort of a chair and an internet-connected gadget. Unfortunately, sedentary lifestyles are a driving force behind burgeoning health care costs, and they pose an alarming threat to the health and well-being of our children. Fortunately, there is cause for hope in lessons from the tobacco control movement and efforts to change smoking behavior. "

Why Does Sitting Still Equal Learning? | Rae Pica - 2 views

  •  
    "Whether we're talking about preschool, elementary through secondary school, college, or even adult learners, I have serious objections to the idea that learning supposedly only comes via the eyes, the ears, and the seat of the pants. Schools -- and policymakers -- have for too long accepted the belief that learning best occurs while students are seated (and quiet, of course). The theory may have been understandable back when they didn't have the research to prove otherwise. But today we do."

Healthiest Way to Work: Standing vs. Sitting and Everything Between - 2 views

  •  
    "Five or more hours of sedentary sitting, according to Dr. David Agus, is the health equivalent of smoking a pack and a quarter of cigarettes. Yikes.

    Yet, sitting around is something we get plenty of practice at. Reading and writing and creating on a computer makes for big chunks of sedentary time. If you're reading this post right now, are you sitting down? How long have you been sitting?"

Good News! Sitting Won't Kill You After All - 1 views

    "Sitting is undeniably one of the comfiest ways to arrange your body. Almost as good as lounging, really, and just short of "dangling worry-free from hammock." But it has acquired a very bad rap over the past few years. A bad rap it doesn't quite deserve.

    Studies say sitting will kill us in all sorts of ways. It will kill us by heart attacks, kidney diseases, chronic diseases, and colorectal cancer. If it doesn't outright murder us, it will shorten our life expectancy and give us mental health issues. Sitting has been compared to smoking. It is the reason I panic-purchased an exercise ball chair from the internet. It is the reason fancier people buy stand-up desks and treadmill desks and have jogging meetings.

    New research from the Mayo Clinic Proceedings joins the pile-on. As Outside pointed out, the Mayo researchers found that every hour you sit reduces the gains of your daily workout by eight percent.

    Are those of us who spend our days in offices, homes, or cafes huddled in front of our computers, taking notes in lecture halls, or otherwise engaged in activities that generally require butt-to-chair contact really so screwed? "

Why not even exercise will undo the harm of sitting all day-and what you can do about i... - 1 views

    "A large review recently published in The Journal of the National Cancer Institute confirms what we've been hearing for years: Sitting can be fatal.

    It's been linked to cancer, diabetes, and cardiovascular disease. In this latest meta-analysis, Daniela Schmid and Michael F. Leitzmann of the University of Regensburg in Germany analyzed 43 observational studies, amounting to more than 4 million people's answers to questions about their sitting behavior and cancer incidences. The researchers examined close to 70,000 cancer cases and found that sitting is associated with a 24% increased risk of colon cancer, a 32% increased risk of endometrial cancer, and a 21% increased risk of lung cancer.

    The really bad news: You can't exercise away the habit's harmful effects. "Adjustment for physical activity did not affect the positive association between sedentary behavior and cancer," the authors write. Even participants who achieved the daily recommended levels of physical activity were at the same risk as those who spent their day sitting. "[The results] indicate that the increased risk of cancer seen in individuals with prolonged time spent sedentary is not explained by the mere absence of physical activity in those persons," the researchers say.

Sitting Is the Smoking of Our Generation - Nilofer Merchant - Harvard Business Review - 6 views

  • As we work, we sit more than we do anything else. We're averaging 9.3 hours a day, compared to 7.7 hours of sleeping. Sitting is so prevalent and so pervasive that we don't even question how much we're doing it. And, everyone else is doing it also, so it doesn't even occur to us that it's not okay. In that way, I've come to see that sitting is the smoking of our generation.
