The Clock Audit

THE BELIEF

“If you can't fall asleep, you just need to try harder.”

THE DATA

Sleep is an involuntary process. Espie's attention–intention–effort model shows that deliberate sleep effort inhibits the automaticity of falling asleep — and a 2022 meta-analysis found that the opposite instruction, gently trying to stay awake (paradoxical intention), produced large improvements in central insomnia symptoms versus passive comparison.

THE BELIEF

“Everyone needs exactly 8 hours of sleep.”

THE DATA

The National Sleep Foundation's expert panel recommends a range — 7 to 9 hours for adults — and explicitly notes individual variation; some people fall appropriately outside the recommended range. "Exactly 8 hours" is a script, not a finding.

THE BELIEF

“One bad night means tomorrow is ruined.”

THE DATA

Harvey and Greenall documented catastrophic worry in insomnia: at night, thoughts about consequences escalate step by step toward worst-case outcomes far beyond what daytime evidence supports. The cognitive model treats this escalating forecast itself as a maintaining factor of the sleeplessness.
