Stand up desks may reduce the risk of obesity, diabetes, cardiovascular disease and cancer if you spend more of your day standing than sitting. James Levine, an endocrinologist at the Mayo Clinic, said “The way we live now is to sit all day occasionally punctuated by a walk from the parking lot to the office.” He also said “The default has become to sit. We need the default to be standing.” There is a new phrase that may be somewhat exaggerated, but helpful none the less. This new phrase is “Sitting is the new smoking.”
Levine started research that was based upon how some people gain weight and others don’t. He had a group of workers who engaged in little routine exercise and put them all on the same diet and forbid them from changing their exercise habits. He and the other researchers discovered that the ones who weren't gaining weight were standing and walking around, on average, 2.25 more hours per day, even though they all worked at sitting desks. Levine stated, “During all of our days, there are opportunities to move around and substantially more,” as he told how he now walks into a colleagues office rather than emailing them, or takes the stairs instead of the elevator. A 2013 study found that standers burn, on average, 50 more calories per hour.
Scientists have researched that in 2013, there has been about 37,200 cases of lung cancer, 30,600 cases of prostate cancer, 12,000 cases of ovarian cancer, 49,000 cases of breast cancer, and 43,000 cases of colon cancer just in the U.S. all because of excessive sitting. They have said that extended periods of sitting creates a higher risk of many forms of cancer.
