The human body is made to move. Actually, the body is designed to stand and walk long distances. Unfortunately, with our information-based society, we no longer use our bodies while working in agriculture or spend as much time outside getting exercise.
These days, much of our days are spent sitting, whether we sit at our desks for 8 hours a day, or sit at home, watching TV or just resting.
A recent study found that, based on 100,000 men and women, the length of time sitting per day had a great determination on how early someone would die. The more a person sits, the more likely they are to die earlier. You may also take a look at http://www.imovr.com/ to gather the details about the standing desk and how it ca prevent the various diseases.
The most surprising part of this study was the fact that even those who had a generally active lifestyle were at risk. This means that if you plan on jogging in the morning and sitting the rest of the day, you are no better off than those that don't exercise at all.
This has a lot to do with blood flow and how our body and muscles are designed. In the sitting position, our blood flow is decreased to the lower portion of our body. Furthermore, our muscles can start to atrophy with sitting over long periods of time. Muscle tissue shrinks and we are no longer able to metabolize calories like we should.
Because most of us have jobs that require us to sit, there isn't a lot we can do to curve the need to sit down. There are a few options, like making sure to take breaks, and we can even go for a walk during lunch (or bring a coworker for a buddy walk).
