Fatigue is more than feeling tired and drowsy, it is a state of mental and/or physical exhaustion that reduces a person's ability to perform work safely and effectively.
Fatigue can be caused by:
- prolonged or intense mental or physical activity
- sleep loss or disruption of your internal body clock
- long shifts
- short recovery times between shifts
- strenuous jobs
- long commuting times
- poor sleep
- family demands
Fatigue may increase the risk of incidents because of a lack of alertness and slower reaction times. It can also affect the ability to make good decisions.
