Job Stress Effects on Workers
Stress sets off an alarm in the brain, which responds by preparing the body for defensive action.
The nervous system is aroused and hormones are released to sharpen the senses, quicken the pulse, deepen respiration, decrease appetite, and tense the muscles.
This response (sometimes called the fight or flight response) is important because it helps us defend against threatening situations. The response is preprogrammed biologically. Everyone responds in much the same way, regardless of whether the stressful situation is at work or home.
Short-lived or infrequent episodes of stress pose little risk. But when stressful situations go unresolved, the body is kept in a constant state of activation, which increases the rate of wear and tear to biological systems. Ultimately, fatigue or damage results, and the ability of the body to repair and defend itself can become seriously compromised. As a result, the risk of injury or disease escalates.
