Does CBT-I outperform sleeping pills for chronic insomnia?
Strong EvidenceYES
Meta-analyses and head-to-head RCTs demonstrate that CBT-I produces comparable short-term improvements to sleeping pills, with superior long-term outcomes and durable effects after treatment ends. Major guidelines now recommend CBT-I as first-line treatment for chronic insomnia.

What the Evidence Shows
Cognitive Behavioral Therapy for Insomnia (CBT-I) is a structured, multicomponent intervention including sleep restriction, stimulus control, cognitive restructuring, sleep hygiene, and relaxation training. Mitchell et al. (2012) conducted a meta-analysis comparing CBT-I directly to pharmacotherapy and found equivalent short-term improvements in sleep onset latency and total sleep time, but CBT-I demonstrated superior outcomes at follow-up after treatment discontinuation. Jacobs et al. (2004) conducted a landmark head-to-head RCT comparing CBT-I to zolpidem (Ambien) and combination therapy, finding CBT-I produced better long-term outcomes at 1-year follow-up, while zolpidem effects dissipated after discontinuation. Trauer et al. (2015) conducted a comprehensive meta-analysis confirming CBT-I produces clinically meaningful improvements: reducing sleep onset latency by 19 minutes, reducing wake after sleep onset by 26 minutes, and improving sleep efficiency by 10 percentage points. These effects are maintained at 6-12 month follow-up without ongoing treatment. The advantage of CBT-I over medications is particularly evident in the long term: medications address symptoms only while being taken and carry risks of dependence, tolerance, and rebound insomnia upon withdrawal. CBT-I teaches skills that persist after treatment. However, CBT-I requires trained therapists, patient motivation, and 4-8 weeks for full effect, creating access barriers compared to readily available medication.

Important Caveats
- ⚠️ CBT-I requires 4-8 weeks for full effect vs. immediate relief from medications
- ⚠️ Access to trained CBT-I therapists is limited in many regions
- ⚠️ Patient motivation and adherence (especially sleep restriction) can be challenging
- ⚠️ Medications may be needed as adjunct for acute crises or during CBT-I initiation
- ⚠️ Digital CBT-I platforms are emerging but have less validation than in-person therapy
Population Studied
Adults with chronic insomnia disorder (symptoms 3+ nights/week for 3+ months); efficacy across age groups
Dosage
CBT-I: typically 4-8 sessions over 6-8 weeks; can be delivered individually, in groups, or digitally. Components include sleep restriction, stimulus control, and cognitive restructuring
Duration
Treatment course 4-8 weeks; effects maintained at 6-12 month follow-up without booster sessions; medication effects disappear upon discontinuation

Meta-AnalysisMitchell MD, Gehrman P, Perlis M, Umscheid CA. · Family Practice (2012)
Meta-analysis found CBT-I produces equivalent short-term efficacy to pharmacotherapy with superior long-term outcomes, as medication effects do not persist after discontinuation while CBT-I gains are maintained.

Insomnia treatment: an overview of current approaches and recommendations for practice and research
Meta-AnalysisRiemann D, Perlis ML. · Sleep Medicine Reviews (2009)
Review argued that pharmacotherapy has distinct merits including immediate efficacy, easier implementation, and broader availability, suggesting that the blanket superiority of CBT-I oversimplifies clinical decision-making for many patients.
Why this disagrees:
Argues medications have legitimate advantages (immediate effect, no therapist needed, broad access) that make them appropriate first-line treatment for some patients, challenging the narrative of universal CBT-I superiority.

Does blue light from screens before bed harm sleep quality?
Moderate EvidenceModerate evidence shows that blue light from screens suppresses melatonin production and can delay sleep onset, but the effect size is smaller than popularly believed. Screen use habits (stimulating content, scrolling) likely matter more than the light itself.
Does CBT effectively treat anxiety disorders?
Strong EvidenceCognitive behavioral therapy (CBT) is well-established as an effective treatment for anxiety disorders, with large effect sizes demonstrated across multiple meta-analyses. It is considered first-line treatment by major clinical guidelines.
