The science of insomnia self-talk: why trying harder to sleep backfires

Good sleepers don't do anything special to fall asleep — that's the point. Decades of research show that the scripts running at 3 a.m. — "I have to fall asleep NOW", "tomorrow is ruined", the glance at the clock — are not side effects of insomnia but part of the machine that keeps it going. This page traces how sleep science moved from bedtime rules to the mind's own commentary: the effort paradox, clock watching, and catastrophic worry loops.
