Americans are far behind the rest of the world when it comes to the number of steps we take in a day. The body mass index numbers and mortality rates of our fellow citizens are rising in direct proportion to time spent seated. Human physiology operates optimally under the physical demands of a significant amount of standing and walking. Much of the now rampant obesity, heart disease, diabetes, and metabolic syndrome can be linked to our species sudden fall into sustained sitting. Standing for most of your workday and a daily habit of walking pays huge health and fitness benefits.
We are de-evolving into a nation of sitters. Between internet, television, driving, and computer work, it is not uncommon for many of my physical therapy patients and fitness clients to sit for ten hours a day. Unfortunately, you cannot train away the metabolic and physical damage created by prolonged sitting with a few 45 minute exercise sessions every week.
Seventy years ago, the London Transit Workers Study provided the initial scientific insights into the powerful health benefits of sitting less and standing more. Take the time to read the recent *article by Gretchen Reynolds in the March 23, 2017 edition of the New York Times. Ms. Reynolds’ provides some valuable information on the benefits of standing up and moving as much as possible. Now go for a walk and then Google Varidesk.
