Most of us have years of sitting experience, consider ourselves quite good at it and would swear that nature intended us to do it as much as possible.
But unfortunately, a good deal of data suggest that we're off our rockers to spend so much time on our rockers — as well as the vast variety of other seats where we're fond of parking our duffs. Here's a sampling of what scientists have learned about the insidious nature of sitting.
The human body was designed for walking, and people did a whole lot of that for millenniums. But lately, not so much. In general, scientists believe, Americans now sit for more than half of their waking hours. Sadly, the sitting position exerts forces on the body that it's not built to accommodate, Davtyan says, and so, as comfy as it may seem, couch potato-hood can lead to a host of woes, including poor circulation and assorted aches and pains.
We're not using much energy when we're sitting still, which is no doubt part of its appeal. But, of course, "not using much energy" is just another way of saying "not burning many calories," which is just another way of saying "watch out for extra pounds." "There is debate as to whether it is the chair or the knife and fork that have caused the increase in obesity rates," Levine writes in a 2017 article. A person with a desk job may burn 300 calories a day at work, he reports, but that same person might burn 2,300 calories a day in a job that requires considerable physical effort.
