Job Stress Effects on Workers
When a person experiences stress—whether physical, mental, or emotional—it sets off a reaction in the brain.
The Fight or Flight Response
This response, often called the fight or flight response, the brain sends signals to the body to get ready for defensive action. The nervous system becomes aroused and a number of stress hormones, such as adrenaline and cortisol, are released into the bloodstream. These changes prepare the body to handle a perceived threat by triggering the following effects:
- Sharpened senses – vision and hearing become more focused
- Quickened pulse – heart rate increases to deliver more oxygen to muscles
- Deepened breathing – lungs take in more air for energy production
- Muscle tension – muscles tighten in preparation for movement or defense
- Decreased appetite – digestion slows to focus energy on survival
The fight or flight response is biologically preprogrammed and happens automatically. Whether the stress is caused by a dangerous situation at work, a tight deadline, or a personal issue, the body reacts in the same way. It’s a natural defense mechanism that can help protect us in the short term.
