Fatigue is a term used to describe an overall feeling of tiredness or lack of energy.
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.
Fatigue is a common symptom of many medical conditions, which range in severity from mild to serious. It’s also a natural result of some lifestyle choices, such as lack of exercise or poor diet.
If your fatigue doesn’t resolve with proper rest and nutrition, or you suspect it’s caused by an underlying physical or mental health condition, see your doctor. They can help diagnose the cause of your fatigue and work with you to treat it.
