Sleep Hygiene Insomnia: What the Evidence Says

Quick Answer

Sleep Hygiene Insomnia has 2 source documents in the current Migaku evidence database. The strongest available sources in this first pass are randomized trial, so conclusions should be framed as evidence-aware guidance rather than medical advice.

Key Takeaways

• This page is generated only from sources stored in the Migaku evidence knowledge base.
• Current evidence mix: 2 randomized trial.
• Claims should be interpreted with the source type, study design, population, and publication date in mind.
• This article is educational and does not replace care from a qualified clinician.

Evidence Map

What The Sources Report

• We found significant short-term improvements in insomnia symptoms and reductions in cannabis use around bedtime in the CBTi-CB versus SHE condition, although the study was not powered to evaluate efficacy over multiple outcomes and follow-ups.This study is the first to demonstrate the possible benefits of CBTi-CB to target insomnia for improving overall functioning and reducing cannabis use as a sleep aid. [Bolling Cecilia (2026); evidence level 2]
• Nonetheless, studies consistently show that withdrawal from frequent cannabis use elicits subjective and objective sleep disturbances.Individuals experiencing cannabis withdrawal symptoms also report difficulty falling asleep and worse sleep quality and objective PSG shows reduced total sleep time and sleep efficiency, and increased night-time wakefulness compared with substance-free controls. [Bolling Cecilia (2026); evidence level 2]
• Long-term consequences include cognitive dysfunction,increased pain sensitivity/opioid use,metabolic imbalance and immune function disruption.Major surgery represents a physiological stressor that is particularly consequential for older adults. [Charles Anaëlle E. (2026); evidence level 2]
• Our recent work showed that these poor sleep qualities and disrupted rhythms predicted cognitive decline, postoperative delirium and progression to AD/ADRD.In addition, we found that insomnia-related sleep/circadian disruption correlated with amyloid/tau burden decades before dementia.All the above factors have been implicated in PND pathophysiology. [Charles Anaëlle E. (2026); evidence level 2]

How To Read This Evidence

Evidence level 1 generally reflects systematic reviews or meta-analyses. Level 2 includes randomized trials, guidelines, or public-health guidance. Level 3 usually reflects observational or narrative-review evidence. Level 4 is weaker or early-stage evidence. The level is a sorting aid, not a final quality grade.

Practical Interpretation

There is trial evidence in the current set, but population and intervention details still matter. For sleep hygiene insomnia, the next editorial step is to add more targeted sources and separate strong findings from early or indirect evidence.

Limits Of This First Pass

This is a small-batch MVP article. It uses the first ingested sources for this topic and should be expanded with more targeted searches, license review, and human editorial checks before being treated as a definitive review.
