This is the first part of a series centered around the theme of adopting healthier habits when working with computers. 1
Let's dive into the most important (and free) step you can take towards a healthier workday.
Too Much Sitting#
Computer workers tend to spend their workdays sitting. A sedentary lifestyle tends to negatively affect health and is associated with increased mortality 2.
Physical strain at work can lead to the development of musculoskeletal symptoms in the neck, shoulder, wrist and hand regions. 3. Additionally, results suggest that stress influences musculoskeletal symptoms too. 3
Is Standing At Work Healthier?#
Not necessarily. If you are mostly standing at work, you may be at greater risk of cardiovascular disease compared to mostly sitting. Combining sitting and standing is likely to be beneficial 6. Interestingly, jobs that combine standing, sitting and walking seem to be more risky for women that for men7
I Work Out. Am I Still At Risk?#
Regular exercise is a must, but probably not enough. It appears that sitting for extended periods can be a risk for chronic disease even if you exercise regularly. 8 The adverse effects of prolonged sitting, cannot be offest by daily exercise alone 9.
Fixing The Sedentary Lifestyle#
Taking Breaks From Sitting#
During your work day, make it a habit to regularly get up and move briefly. Having a higher number of breaks in sedentary time appears to be more beneficial 2.
How Often Should I Stand?#
A good sitting/standing ratio is perceived to be around 24:6 10. That is 24 minutes sitting, 6 standing. This approximates the standard ratio used by the Pomodoro technique (25:5) 10 and may be a good point of departure:
- Set a timer for 25 minutes. Start working on tasks.
- Then, take a 5 minute break. Get up and move away from you desk. Try being lightly/moderately active. Walk around, stretch, maybe do a bit of light strength training. Repeat.
Practice "active sitting"#
Even when sitting, actively adjust your posture: Regular small movements might aid the prevention of Chronic Lower Back Pain. associated with sitting too still. 11
