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

3 the researchers behind it — 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 fa

Allison G. Harvey

Known for:The cognitive model of insomnia — showing how worry, monitoring and distorted perception of sleep maintain sleeplessness.

Key findings

  1. 2002

    Proposed that insomnia is maintained by excessive negatively toned cognitive activity: worry triggers arousal and selective attention, which distort the perception of sleep and feed further worry. ↗

  2. 2003

    With Catherine Greenall, documented catastrophic worry in primary insomnia: night-time thoughts escalate stepwise toward worst-case daytime consequences. ↗

  3. 2007

    With Tang and Schmidt, showed experimentally that instructed clock monitoring causes more sleep-related worry and longer sleep onset in people with insomnia. ↗

Colin A. Espie

Known for:The attention–intention–effort pathway — the formal account of why trying to sleep blocks sleep.

Key findings

  1. 2002

    In a major review, framed persistent insomnia as a failure of the normally automatic sleep process, setting up psychological rather than purely behavioural accounts of its persistence. ↗

  2. 2006

    With colleagues, proposed the attention–intention–effort pathway: selective attention to sleep, explicit intention to sleep, and sleep effort inhibit sleep-wake automaticity and develop psychophysiologic insomnia. ↗

Karolinska Institutet

Markus Jansson-Fröjmark

Known for:Meta-analytic evidence for single components of insomnia treatment — including paradoxical intention and stimulus control.

Key findings

  1. 2022

    Led the first systematic review and meta-analysis of paradoxical intention for insomnia, finding large improvements in central insomnia symptoms relative to passive comparators. ↗

  2. 2024

    Led a systematic review and meta-analysis of stimulus control as a standalone insomnia intervention, supporting the Bootzin-lineage protocol on its own. ↗
