mental effort

Thinking that tires

Mental effort is the exertion required to think, concentrate, or solve problems.

It describes the cognitive strain of difficult tasks—learning a new skill, following complex instructions, or pushing through fatigue to stay focused: Reading philosophy takes real mental effort.

Unlike physical effort, mental effort depletes without visible signs, though the exhaustion is equally real.
