Debunking the Myth of ‘Good Posture’ (Part 1)


We’re Not Designed to Sit Up Straight

It frequently astounds me no matter where I go people say, “It’s my fault I’ve got a sore back, or a sore neck – I have such lousy posture”. 

But surely if good posture was so good for us – wouldn’t it be easier to maintain? 

There’s no debate on the negative effects of sitting for long periods of time. The human body needs to move.

However, even though it’s not good for us – the modern world requires many of us to work in sedentary postures for extended lengths of time –especially at computers.

Many of us can’t avoid sedentary work but we can position our bodies to avoid negative consequences – and of course be comfortable. 

For decades and even today, many health professionals and governing bodies still advocate the ‘sit-up-straight posture.'

We all know it:

  • Back up straight (to imitate a standing posture)
  • Hips and knees at 90 degrees
  • Elbows below shoulders
  • Chin tucked in and looking straight ahead

We also know it’s impossible to maintain this posture. 

Why do humans find it so hard to sit up straight for long periods of time?

It’s not hard to maintain a comfortable upright posture when we’re standing.

So, why is it so hard to have an upright posture when we’re sitting?

Standing up straight is a functional human posture. It’s natural and it doesn’t take any conscious effort to maintain. 

This is not the case for sitting up-straight for long periods of time. Just because it’s natural to stand up straight, doesn’t mean it’s natural to have your back in the same position when you sit.

This is Part One in a series of articles I’m going to be doing on what a good posture really is.  Keep an eye out for Part Two next month which will further explain why we’re not designed to sit up straight.
