The state of being 'tired but wired' in the middle of the night is caused by an overactive alertness system rather than a lack of physical fatigue, and using the 'Cognitive Shuffle' can help quiet mental agitation to fall asleep.
The explanation that nocturnal 'tired but wired' states stem from an overactive alertness system (hyperarousal) is well-supported by research.
