When does the over-fatigue occur

When does the over-fatigue occur

• A. After long breaks
• B. After systematically starting work in residual fatigue
• C. After finishing a shift
• D. Immediately at start of work

Answer: (B)

Over-fatigue happens when you begin a new work period while still carrying fatigue from before—the residual fatigue that remains after rest. If you systematically start work in this fatigued state, each shift compounds the tiredness and performance declines more quickly, so you reach over-fatigue during the work period itself. Breaks that are long enough help restore fatigue, reducing the likelihood of starting a shift already fatigued. Finishing a shift leaves you fatigued, but the critical onset of over-fatigue is driven by starting with residual fatigue, which is why this option best describes when over-fatigue occurs.
