When we exercise our body to fatigue, it takes less to get back to that point of fatigue if we do another set of the same exercise within a close enough timespan.
And even after we’re done with our workout, it can take anywhere between 24 – 72 hours before our body is fully recovered… which means we’re in a prolonged state of it requiring less to get us back to that point of fatigue.
This is how it is for mental fatigue as well.
If we push our minds to a point of complete mental fatigue, it’ll require less to get back to that point for at least a day thereafter. And the closer in proximity we are to that initial point of complete fatigue, the easier it’ll be to become re-fatigued.
The reason this is important to understand is because in life… we’re constantly getting hit with mentally fatiguing tasks, challenges, and experiences.
And if we’re not mindful of where we are on this Fatigue Threshold Spectrum… then we might not act in alignment with what our mind needs to perform optimally and most efficiently.
Just like the muscle group that we fatigued needs 24 – 72 hours of rest to fully recover… so, too, do the mental muscles we flexed to similar points. And if we don’t follow this protocol, then we’ll just hit fatigue quicker, using muscles that aren’t fully recovered, and only prolong our full recovery out further.
So either a) get in the habit of stopping at your 70% fatigue level so you can recover quicker or b) find ways you can give yourself more time to get back towards 0 after pushing yourself to 100%.
