There is worldwide interest in how to make office computer work more dynamic by using sit-stand workstations. There is clear evidence that over sitting can be hazardous to your health, just as over standing can detrimentally affect your health (see : CUergo: Sitting and Standing).Programs promoting the health and performance benefits of building more movement into your workday have been launched in several countries, including the USA, UK, and Australia.
Based on research studies I recommend the 20 minutes sitting (in a good posture), 8 minutes standing (for sit-stand workstations) and 2 minutes of standing and moving (gentle stretching, walking etc.) as a ball park goal for organizing work. For a 7.5 hours workday (lunch is excluded) this means a daily regimen with a total of 5 hours of sitting, 16 sit-to-stand changes, 2 hours of standing and .5 hours of moving. These numbers aren’t hard and fast a company can design their work so employees can be more active. This sit-stand-stretch cycle is shown in the following simple diagram. Following this movement pattern throughout the day should keep employees comfortable, healthy and productive.
