“Sitting is the new smoking” is the slogan the Australian government are using to highlight the dangers of prolonged sitting and inactivity [i]. Living a sedentary lifestyle increases the chance of becoming overweight, developing heart disease and type II diabetes and mental health issues. Having studied physiotherapy and witnessed the injuries associated with prolonged sitting, these effects do not surprise me. The human body is engineered to stand. Our hearts, digestive organs and musculoskeletal system are more efficient in standing. It is no wonder that if we avoid this natural posture, the effects can be detrimental.

Weight Management

Sitting for prolonged periods can result in weight gain and obesity[ii]. Through movement and contracting our muscles, we burn off the fats and sugars we eat. If we spend a lot of time sitting, our muscles remain in a non-contracted state causing us to retain these fats which eventually get converted to glycogen stores, resulting in weight gain. Even if you regularly exercise but spend a large amount of time sitting, you can still develop health problems such as metabolic syndrome which increases your risk of diabetes, stroke and heart disease.
On the contrary, standing has been shown to reduce your risk of weight gain. When we stand, the large muscles in our buttocks (glutes) and thighs (quads) are active or contracted, resulting in more calories burned.
In 2012, a study in the Journal of Physical Activity and Health investigated the difference in calories burned between students sitting at a traditional seated desk and students working at a standing desk. The results indicated a significant increase in calories burned for subjects that were at the standing desk compared with the seated group[iii].

Reduced injury rates

Sitting does not only result in less muscle contractions; it also takes our joints out of their  natural anatomical position and leads to abnormal postures that increases the risk of injury.
When sitting, our hips are flexed which can cause shortened hip flexor muscles and soft tissues. This leads to tight hip joints and altered body movements which can result in other muscles having to compensate for the loss in flexibility[iv].
Back pain can also be aggravated by sitting. A significant portion of the population (25–50%) is known to develop acute low back pain (LBP) during prolonged sitting[v]. Poor posture while sitting may also result in lengthened muscles and tendons of the back leading to an increased risk of chronic back pain.
Standing, and in particular, the change from a sitting to a standing desk has been shown to reduce back pain[vi]. In addition to this study, Pronk et al. 2011 found that participants who spent an average of 66 minutes of their workday standing experienced a 54% reduction in upper back and neck pain compared to sitting[vii].

Improved Productivity and Mental health

The benefits of standing while working are not restricted to physical health. Improvements in productivity and mental health have also been demonstrated. A 2016 study carried out over 6 months demonstrated that employees who were at standing desks were significantly more productive than seated employees[viii].

Although the link between prolonged sitting and mental health is not fully understood, we do know that the risk of anxiety and depression is higher in people that sit more. This may be because people who are spending a lot of time sitting are missing out on the positive effects of physical activity. Pronk et al. 2011 also showed that 33% of participants felt reduced levels of stress after using a sit to stand desk.
The evidence clearly demonstrates that standing desks are beneficial for every physically capable desk user.
In order to maximise these benefits and minimise any risks, there are guidelines I would advise:  
  • A regular change of position is the important thing to take from the evidence. Although prolonged sitting has detrimental effects, standing in the same position for a full working day can also have its draw backs. Buckley et al. 2015 recommend workers to initially aim for two hours standing per day, eventually progressing to a total of four hours per work day[ix].
  • Whether you are sitting or standing, working with an improper posture or poor ergonomic set up can cause injury and negative health consequences. Ensure your work space is set up properly and regular breaks from postures are taken.
  • Even if you adopt a stand desk and feel the benefits, it does not simply replace physical exercise. In my opinion the slogan should be changed from “sitting is the new smoking” to “being static is the new smoking”.
