![]() There's this kind of general idea out there that running is like driving your car too much - it's wear and tear, and that running is highly stressful and it just wears away your cartilage, just like driving your car for a long period of time wears out your springs, for example. On the idea that running is bad for your knees Until recently, all human beings pretty much either sat on the ground or, if they did have chairs, they were stools or benches or things like that. But until recently, only really rich people - the pope or the king - had a chair with a seat back. We all think that it's normal for a chair to have a seat back. On how chairs with backs have contributed to our back pain And that kind of interrupted sitting, as well as not sitting in a chair that's kind of nestling your body and preventing you from using any muscles, all that kind of keeps your muscles going and turns out to be a much healthier way to sit. In hunter-gatherer camps, people are getting up every few minutes, to take care of the fire or take care of a kid or something like that. So the evidence is that interrupted sitting is really the best way to sit. It uses up fats in your bloodstream and sugars in your bloodstream, and it produces molecules that turn down inflammation. And your muscles, of course, are the largest organ in your body - and just turning them on turns down inflammation. Just getting up every once in a while, every 10 minutes or so - just to go to the bathroom or pet your dog or make yourself a cup of tea - even though you're not spending a lot of energy, you're turning on your muscles. Shots - Health News Sit More, And You're More Likely To Be Disabled After Age 60 But if you look at how much people sit when they're not at work, well, then the numbers get a little bit scary. So if you look at how much time people spend sitting at work, it's not really that associated with heart disease or cancers or diabetes. As I started to explore the literature more, I was fascinated because most of the data that associates sitting a lot with poor health outcomes turns out to be leisure-time sitting. It's not unnatural or strange or weird to sit a lot, but it is problematic if, of course, that's all you do. So it turns out that I think we've kind of demonized sitting a little falsely. Some friends and colleagues of mine actually put some accelerometers on some hunter-gatherers and found that they sit on average about 10 hours a day, which is pretty much the same amount of time Americans like me spend sitting. When I walk into a village in a remote part of the world where people don't have chairs or a hunter-gatherer camp, people are always sitting. On the demonizing of sitting as "the new smoking" Why would anybody do something like that?" "When I go to these villages, I'm the only person who gets up in the morning and goes for a run. "Until recently, when energy was limited and people were physically active, doing physical activity that wasn't necessarily rewarding, just didn't happen," Lieberman says. He says that the notion of "getting exercise" - movement just for movement's sake - is a relatively new phenomenon in human history. It was an active lifestyle, but one thing it didn't include was any kind of formal exercise.ĭaniel Lieberman is a professor in the department of human evolutionary biology at Harvard. to get some benefits of physical activity."įor much of history, human beings needed to be physically active every day in order to hunt or gather food - or to avoid becoming food themselves. "You don't have to do incredible strength training. That's good, says Exercised author Daniel Lieberman. With the pandemic, many people are turning to at-home workouts and walks in their neighborhoods.
