The Bowling Ball and the Pin: How Poor Posture Causes Neck Pain

The Bowling Ball and the Pin: How Poor Posture Causes Neck Pain

The average human head weighs about 3.6kg. Each day we all walk around with a bowling ball (our head) balancing on a toothpick (our neck). We are designed this way to allow for the full range of motion we all know and love. Even under the best circumstances, this places a lot of stress on our spine. But leaning forward even just 15 degrees pushes that weight up to 13kg, and with a 30 degree tilt it’s closer to 18kg!  (That’s 5 bowling balls on top of neck!)

Why it Matters:

Driving a car, working on the computer, and using a tablet/phone all usually result in less than ideal posture. And when you start to lean forward, it places a tremendous amount of extra pressure on the discs in your neck and spine. This can cause increased compression and lead to pain. Even just a few centimetres of forward head posture can double or triple the amount of stress on the spinal joints in your neck.

  • The average human head weights approximately 3.6-4.5kg.
  • For every 2.5cm of forward head posture, an additional 4.5kg of weight is added to your spine.
  • Forward head posture may result in muscle imbalances, a high risk for spinal degeneration, reduced range of motion, and pain.

Next Steps:

Take a moment today at work and notice if your shoulders are rounding, the head has moved forward, and upper back is hunched over. If you see yourself slouching into this posture, let us know. We would love to provide you with some exercises you can do at work to help strengthen the muscles supporting your spine and combat these muscle imbalances. And remember, the more time you spend in this posture, the more likely you are to suffer head and neck pain.
