Blog Post #1414 – The Link Between Psychosocial Risk Factors and Musculoskeletal Injury – Part Two

Original Report by Theo Heineman

Report from the OH&S Canada magazine – (Sept 2021)

Chronic stress is a lot like a motor that is revving too high for too long, and after a period, can have a cascading effect on the body.

In addition, stress-induced physiological factors can be linked to musculoskeletal injuries (MSI) and disorders:

  • Stress hormones like adrenaline and cortisol continually coursing through the body catabolize and harden tissues and arteries causing greater muscle tension. This is turn results in symptoms such as stiff muscles and high blood pressure.
  • Stress sustained over time causes the body to release cortisol, inhibiting muscle repair and immune system function so bodies cannot recover properly.
  • Stress-induced increased blood pressure can lead to pressure in joints, specifically on ligaments, nerves and tendons, increasing the risk for carpal tunnel syndrome.
  • High stress in the body can result in decreased sensitivity to pain, resulting in workers pushing themselves beyond their body’s physical capacity.
  • When in stress, the pupil of the eye opens or dilates. This can result in greater sensitivity to light.
  • A worker experiencing stress or frustration may overexert their body, resulting in muscle strains and sprains.

Theo Heineman is a regular columnist for the OH&S Canada magazine.
