Summary
The 2024 Cochrane systematic review consolidates 261 randomized trials of hypnotherapy as a sleep-latency intervention (Cochrane Collaboration, 2024). The pooled effect estimate is a 12-minute mean reduction in sleep latency for adult populations aged 18–65.
Evidence review
Evidence is graded high for adult populations and limited for adolescents.
Sleep latency
28 trials (n=2,184) reported sleep latency as primary outcome.
Efficiency
19 trials (n=1,521) reported sleep efficiency improvements of +8.2%.
Population gaps
Only three trials reached inclusion thresholds for adolescent populations — a priority research gap.
