Staying in shape: A study by O'Sullivan showed that standing positions increase muscle activity and can burn more calories. The Texas A&M University School of Public Health found that study subjects who used standing desk for six months experienced a 75 percent reduction in physical discomfort.

Health boost: It's well known that sitting all day increases the risk of heart disease, back pain, obesity and diabetes, according to Dr. Emmanuel Stamatakis, who said the risk of premature death is 32 percent lower for people who work in a standing position than for those whose daily work is dominated by sitting. Maintaining a fixed posture for long periods of time is harmful to health and can increase physical stress in the long run.

Improve productivity: Texas A&M University study found that employees switched to sit stand desk after a maximum of 46% increase in productivity. Researchers tested the productivity of two call center employees over a six-month period and found that employees who used adjustable height desk were much more efficient.

The easiest way to extend life.
Before getting exhausted and quitting your desk job, consider this simple solution: An electric standing desk will allow you to spend less time sitting down each day while still getting work done. With the push of a button, you can change your sitting position from sitting to standing and potentially increase your life expectancy.

According to the "Sedentary Behavior and Life Expectancy in the United States" study, if you limit your sitting time to less than three hours a day, you can increase your life expectancy by 2 1/2 years.

If that's not convincing enough, consider one of the earliest studies of physical activity at work. London bus drivers in 1950 were found to have twice the risk of developing coronary heart disease than their more active counterparts - the conductors who collected tickets. Since then studies with sitting down have been strongly associated with diabetes, cardiovascular disease and all-cause mortality over time.

I sit at work a lot.

My entire business is online, and I do most of my work on the computer every day.

The research over the last few years about the health risks of sitting has really started to bother me. Studies link sitting for long periods of time (whether in front of the TV, or in front of your car) to obesity, cardiovascular disease and cancer.

Studies show that men who sit for six hours or more have a 20 percent higher mortality rate than men who sit for three hours or less. For women, frighteningly, it's 40 percent higher.
