What is cumulative fatigue primarily caused by?

Cumulative fatigue primarily stems from long-term sleep disruption, which can accumulate over time and significantly impact an individual's overall performance and well-being. This condition arises when an individual consistently fails to obtain adequate, restorative sleep, leading to a gradual build-up of fatigue that can affect cognitive functions, emotional stability, and physical health.

Long-term sleep disruption can be due to various factors, such as work schedules, lifestyle choices, ongoing stress, or medical conditions. Over time, the lack of quality sleep leads to an increasing deficit in energy and alertness, creating a state where recovery becomes progressively more challenging. It is essential to address long-term sleep quality to manage cumulative fatigue effectively and promote better health outcomes.
