Before 2010, if you wanted to binge-watch a show in Canada, you needed a pile of DVDs. But when streaming services like Netflix entered the market, suddenly we were able to watch our favourite shows for hours on end – without even having to get up to change the disc. Seems like a small thing, but it’s one more habit that encourages idleness. Timothy Caulfield, a professor in the School of Public Health at the University of Alberta, says our love of streaming is part of a larger shift toward inactivity. That said, there has been a recent pushback against sedentary behaviour. “We’re seeing standing desks and even walking desks and recognizing that you can’t necessarily alter an unhealthy lifestyle with one half-hour workout here and there,” he says.
