Matt examines "revenge bedtime procrastination," where individuals voluntarily delay sleep to reclaim autonomy. Distinguishing this "unlocked door" from the "locked door" of insomnia, he uses global data to explain how smartphones and low agency trigger this behavior which then leads to chronic sleep debt and impaired cognitive function.

Matt goes on to link sleep irregularity to all-cause mortality, noting how inconsistent timing compromises long-term health. He offers such solutions as "implementation intentions" - ‘If-Then’ plans - proven in trials to reduce delay. By addressing chronotype conflict and the "Monday effect," our host provides a scientific protocol to align biological rhythms for restorative sleep.
