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.
