At Dee Why Chiropractic Care we treat a lot of office workers complaining of headaches, neck and low back pain caused by sitting for prolonged periods without a break!

As humans we are meant to be upright and are built for movement. Anatomically we haven’t changed much from our “hunter/gatherer” ancestors however our lifestyles have quite significantly. A large percentage of the population live very sedentary lives, working hours on end at a desk and getting little exercise.

Lets go through some of the most common conditions associated with sitting for prolonged periods:

Postural changes

When we sit, we tend to slouch. It is almost unavoidable. You can sit with good posture until the muscles fatigue and then you begin to slouch. Over the years our posture adapts to our lifestyles, which can manifest into painful conditions and premature degeneration of our spinal joints.

Weakened core

Having a strong core is important as it plays a major role in protecting the spine. However when we sit, the core is less active/contracted hence there is more pressure put on the spinal joints. Use it or lose it…heard it before? Sitting for too long leads to core muscle deterioration and fat accumulation around the abdomen.

Weak legs and glutes

Our leg muscles are meant to be strong as they are supposed to be supporting our body. As mentioned earlier when we don’t use them, we lose them. So our muscles start to waste and without strong gluts and legs to stabilise us, you are at increased risk of injury.

Muscle imbalances

Muscle imbalances occur with poor posture. Some muscles become tight and some become weak. Ultimately leading to altered mechanics of the body and increased stress on the joints (particularly the spine) that may lead to some painful conditions.

Neck and low back pain

Sitting for prolonged periods with bad posture leads to increased stress on spinal joints; commonly the discs in the low back become compressed. Compressed discs can lead to conditions such as annular tears, pinched nerves and sciatica.

The human head approximately weights about 4-5kg and while we sit our head is typically in the forward position or looking down. What this does is increase the load on the neck and shoulder muscles, as they have to work harder to support the head. This leads to tight shoulders that can lead headaches and changes in the neck curve that can lead to chronic pain and spinal degeneration.

Increased weight

No surprise here. Increased weight increases stress on your joints.

Diabetes and Heart Disease

Studies have shown that people who have sedentary lifestyles have an increased risk of developing diabetes and/or heart disease.

Moving is good for your spine and overall health. Sitting for too long increases the risk of chronic health problems such as obesity, heart disease and diabetes. 

Steps to break the cycle:

  • Get out and move
  • Take regular breaks from sitting
  • Have your work station ergonomically assessed
  • Get a standing or adjustable desk
  • Get a back support
  • Stretch tight muscles and strengthen weakened muscles
  • When sitting try your best to sit upright and engage your core
