Studies have shown a heightened risk of heart disease among those people who spend most of their days sitting. According to NPR, a 2010 study found that &quot;men who reported more than 23 hours a week of sedentary activity had a 64 percent greater risk of dying from heart disease than those who reported less than 11 hours a week of sedentary activity.&quot; For IT professionals who spend most of their time sitting in front of a computer, this should sound an alarm.
