The central concept behind the phenomenon of ego depletion is the idea that ego strength is like a muscle that can be built up or atrophied. Ego depletion refers to the idea that self-control is a finite resource that can be exhausted if it is used too much. This concept is based on the idea that the prefrontal cortex, which is responsible for executive functions such as decision-making, planning, and self-control, requires a lot of energy to function properly. Just as muscles can become fatigued after a strenuous workout, the same is true for self-control. Therefore, it is necessary to take breaks to recharge and restore self-control.
