We are a nation of sitters, we sit when we work, when we eat, when we drive, watch TV, write, draw, read, research, while we wait for an appointment, catch public transport, fly, drink coffee... you get the picture. So what effect does all this sitting have on us? In particular, how does sitting in one position affect us?

First of all, let’s get one thing straight, humans are designed for movement. Sitting for long periods of time can lead to an increase in musculoskeletal problems such as back, neck and shoulder pain and sciatica. Other issues such as digestive problems and shallow breathing can be worsened by static seating.

But what about the 90° ergonomic seating structure (above) that is often recommended?
Even this position is being challenged by some ergonomists nowadays.

At work we alter our positions naturally even whilst sitting at a workstation with miniscule adjustments. Making some basic alterations to our workstation can help prevent injury and drastically reduce the amount of pain and injury we may experience. Movement has been associated with improved brain function so chances are you’ll work more effectively as well.

The ability to sit in various postures is key as it allows movement. According to Galen Cranz, a leading international authority on the chair and sitting, we need to change the way we work so that we are not putting pressure on the same parts of our body for extended periods. The ideal situation would be to lie down, semi-recline, sit on the floor, stand, half stand and sit while doing our daily activities including work.

If you are limited to your desk and chair situation, scrutinising the chair you sit on is the most obvious start when looking at the way you sit. Does it adjust, does it allow you to move and sit in various positions?

Industry leaders in Europe have been quick to incorporate the latest philosophy into their designs.

A new one that has just come on the Australian market is the Award Winning German active seat, the ONGO®, which has also recently been nominated in the prestigious 2012 German Design Award.

Carrying out certain exercises on the chair, such as circling the hips, creates an effective back and core workout that can easily be integrated into the daily routine playfully and with no loss of time - at the office, the gym or at home.

Another favourite is the Scandinavian HÅG chair as you can sit in it about 5 different ways (including backwards!). The saddle inspired chair specifically allows you to sit-stand which puts less pressure on your back and hips.

So take a moment to be aware of your posture, your workstation and your chair. When you are finished reading stand up, stretch and most importantly... Move.
