Just when you thought that if there was one place in this world you were safe it would be your favorite easy chair, a growing body of research has emerged suggesting that too much time spent sitting could be putting you at greater risk of developing cancer.
Findings presented last month at the American Institute for Cancer Research in Washington, D.C. say that simple routine exercise does not negate the risk of cancer in people who live otherwise sedentary lifestyles, to the tune of nearly 49,000 cases of breast cancer and 43,000 cases of colon cancer that could have been prevented by just spending less time sitting.
Dr. Neville Owen, with the Baker IDI Heart and Diabetes Institute in Melbourne, Australia, attributes the risk to the physiological effects of inactivity on a sedentary body. According to Dr. Owen, long periods of muscle inactivity produce biological signals known as “biomarkers” that have been linked to cancer: “It's been surprisingly consistent with what strong relationships there are between physical inactivity and these biomarkers of cancer risk.”
Other research published in 2002 found that the levels of biologically available sex hormones, the excess of which could lead to hormone-related cancers such as those of the breast, ovaries or prostate, could be reduced through physical activity. The established advice from cancer researchers has long been that we should be getting a certain amount of exercise per week (the US Centers for Disease Control and Prevention recommend 150 minutes of moderate exercise per week), and no one is trying to invalidate that advice. However, there may be much more to staying active to curtail cancer than regular exercise.
Alpa Patel, strategic director for the American Cancer Society's Cancer Prevention Study-3, says that “there’s benefit in just moving around.” This “moving around” can be anything from taking the stairs to your office to getting up for a cup of water every once in a while, and every effort you take throughout the day to make your body move and respond works to reduce the risk of cancer. While it may raise alarms in the many workers who spend up to an estimated fifteen and a half hours a day sitting, Joan Vernikos, former director of life sciences at NASA, says that just standing up every thirty minutes or so can be helpful.
And think about it: now instead of sending droll e-mail to colleagues around the office, why not amble on over to their desks and give them the benefit of your charm in person, while reducing your risk of cancer at the same time? Your body will thank you for it.
