What is Fatigue?
Fatigue is a term used to describe an overall feeling of tiredness, lack of energy, and feeling unable to complete daily tasks. It is often accompanied by other symptoms like muscle weakness, headaches, difficulty concentrating, and mood changes.
Types of Fatigue
There are a few main types of fatigue:
- Chronic fatigue: Persistent, long-term exhaustion that lasts 6 months or longer and interferes with regular activities. This severe fatigue usually has an underlying medical cause that needs treatment.
- Acute fatigue: Temporary tiredness from short-term exhaustion. This is the normal fatigue people experience from day-to-day stress, poor sleep, overwork, or jet lag.
- Muscle fatigue: Lack of strength after exercise or physical activity from overworked muscles. This muscle tiredness will resolve after rest.
- Mental fatigue: Difficulty concentrating, decreased motivation, and cloudy thinking from prolonged cognitive or mental exertion.
