When does fatigue occur?

Fatigue occurs when the body and mind are depleted of energy and no longer able to function at their optimal levels. Fatigue can be both physical and mental, and it can range from mild to severe.

Physical fatigue can be caused by a number of factors, including:

* Overexertion: Pushing the body beyond its limits can lead to fatigue, especially if the activity is strenuous or repetitive.

* Lack of sleep: Not getting enough sleep can leave the body feeling tired and drained.

* Dehydration: When the body is dehydrated, it can't function properly, which can lead to fatigue.

* Nutritional deficiencies: Not getting enough of certain nutrients, such as iron or vitamin B12, can also lead to fatigue.

* Medical conditions: Some medical conditions, such as anemia or thyroid problems, can cause fatigue.

Mental fatigue can be caused by a number of factors, including:

* Stress: Chronic stress can take a toll on the body and mind, leading to fatigue.

* Anxiety: Anxiety can cause the body to feel tense and restless, which can interfere with sleep and lead to fatigue.

* Depression: Depression can cause a loss of interest in activities and a lack of energy, both of which can lead to fatigue.

Fatigue can be a debilitating condition that can interfere with work, school, and personal life. If you are experiencing chronic fatigue, it is important to see a doctor to rule out any underlying medical conditions.
