exhaustion

Exhaustion is a state of being incredibly tired. Running a marathon on a hot day often results in exhaustion.

Your exhaustion might be due to physical fatigue, after shoveling snow for hours or chasing after your runaway dog, or mental tiredness.

Exhaustion comes from the verb exhaust, "a drawing off," specifically of strength. from the Latin exhaurire, "draw off" or "take away."
