What is fatigue?
Fatigue is a common problem involving a physical and mental state of being tired and weak. Physical and mental fatigue are different, but they often occur together. Long-term physical exhaustion can also lead to mental fatigue. A lack of sleep can both result from and increase the risk of a number of medical conditions. Fatigue can prevent a person from fulfilling their usual tasks. It can make it hard to get out of bed in the morning. When it affects safety, for example, on the road, it becomes a public health concern.
How many types of fatigue are there?
There are mainly two types of fatigue:
- Physical: A person finds it physically hard to do the things they normally do or used to do, for example, climbing stairs. It includes muscle weakness. Diagnosis may involve a strength test.
- Mental: It is harder to concentrate on things. The person may feel sleepy, have a decreased level of consciousness, and in some cases show signs similar to that of an intoxicated state.
What’s the difference between fatigue or sleepiness?
Sleepiness can happen when a person does not have enough good-quality sleep, or when there is a lack of stimulation. It can also be a symptom of a medical condition. It is more likely to be short term. Sleepiness, or drowsiness, may be solved by getting a good night’s sleep. Chronic fatigue is usually linked to a medical problem. Drowsiness and fatigue can be life-threatening, for example, if it impairs a person when driving a vehicle or operating heavy machinery.
