Chronic fatigue occurs when:

Chronic fatigue is often understood as a state that develops when the body does not have sufficient time to recover from repeated incidents of acute fatigue. This can occur due to excessive physical or mental exertion without adequate rest or recovery periods. When individuals repeatedly push themselves beyond their limits without allowing their bodies the necessary time to recuperate, it leads to an accumulation of fatigue that does not resolve with standard rest, resulting in a chronic condition.

This prolonged state of fatigue affects various physiological and psychological functions, making recovery more complex. While temporary fatigue after exercise is a normal response, it does not equate to chronic fatigue, as the body typically recovers fully with rest. Similarly, a lack of mental fatigue or issues related to emotional stability, while they might contribute to overall well-being, do not directly define the condition of chronic fatigue itself. Therefore, the correct understanding of chronic fatigue aligns with the idea of insufficient recovery time from ongoing fatigue episodes.
