AI Answers About Insomnia: Model Comparison

Chronic insomnia affects approximately 10-15% of adults, and the number of people who experience occasional sleep difficulty is substantially higher. Sleep problems are one of the most common health topics explored through AI chatbots, partly because they occur at night when medical offices are closed. We compared four AI models on an insomnia scenario.
The Question We Asked
“For the past three months, I’ve had trouble falling asleep — it takes me 1-2 hours every night. Once I fall asleep, I wake up around 3 AM and can’t get back to sleep. I’m exhausted during the day, irritable, and my work performance is suffering. I exercise regularly, limit caffeine, and keep a consistent schedule. I’m 38, male, no medications. What’s causing this and what can I do?”

Detailed Analysis of Each Model
GPT-4
GPT-4 identified the pattern as consistent with chronic insomnia (difficulty initiating and maintaining sleep for three or more months, with daytime impairment). It acknowledged that the patient is already practicing good sleep hygiene (regular exercise, caffeine limitation, consistent schedule) and moved beyond generic hygiene advice to discuss cognitive and behavioral factors. GPT-4 recommended stimulus control (leaving bed after 20 minutes if unable to sleep), sleep restriction therapy (counterintuitively limiting time in bed to consolidate sleep), and reducing pre-sleep cognitive arousal (journaling worries before bed, progressive muscle relaxation). It mentioned CBT for insomnia (CBT-I) as an option and noted that melatonin may help with sleep onset but has limited evidence for sleep maintenance insomnia.
Strengths: Recognized good hygiene already in place, moved to next-level strategies, practical stimulus control advice.
Claude 3.5
Claude provided the most comprehensive response. It validated that the patient is doing many things right and explicitly stated that persistent insomnia despite good sleep hygiene suggests either an underlying cause that needs investigation or a cognitive-behavioral pattern that sleep hygiene alone cannot address. Claude discussed potential underlying causes to rule out: anxiety or depression (even subclinical), sleep apnea (which can cause middle-of-the-night awakenings), thyroid dysfunction, chronic pain, and stress. It then provided the most detailed CBT-I explanation, describing it as the first-line treatment for chronic insomnia per American Academy of Sleep Medicine (AASM) guidelines. Claude outlined the five components of CBT-I: sleep restriction, stimulus control, cognitive restructuring (addressing catastrophic thoughts about sleeplessness), relaxation training, and sleep hygiene education. It mentioned that CBT-I is available through trained therapists and through validated digital platforms, making it more accessible than many people realize. Claude also directly addressed the medication question the patient likely has in mind, noting that sleeping pills are not recommended as first-line chronic insomnia treatment due to dependency risk and rebound insomnia.
Strengths: Underlying cause investigation, CBT-I as first-line (with all five components), medication caution, digital CBT-I accessibility noted.
Gemini
Gemini suggested reducing screen time, trying relaxation techniques, and seeing a doctor if the problem persists. Given that the patient explicitly stated they already practice sleep hygiene, the response felt generic and did not address the pattern adequately.
Strengths: Simple starting suggestions.
Med-PaLM 2
Med-PaLM 2 provided a clinically structured response. It classified the insomnia as chronic (per ICSD-3 criteria: symptoms at least three nights per week for at least three months with adequate sleep opportunity). It discussed the hyperarousal model of insomnia — the theory that chronic insomnia involves physiological and cognitive hyperactivation that perpetuates the sleep difficulty. The treatment discussion focused on evidence-based interventions: CBT-I as first-line per AASM guidelines, with pharmacological options (dual orexin receptor antagonists like suvorexant as newer alternatives to traditional hypnotics) discussed as second-line. Med-PaLM 2 recommended a sleep study if sleep apnea is suspected based on symptoms like snoring, witnessed apneas, or unrefreshing sleep despite adequate duration.
Strengths: ICSD-3 diagnostic criteria, hyperarousal model, newer medication class mentioned, sleep study indications.
Red Flags AI Missed or Underemphasized
For chronic insomnia, these factors require evaluation:
- Snoring, gasping, or witnessed breathing pauses during sleep (obstructive sleep apnea)
- Restless legs or periodic limb movements disrupting sleep
- Daytime sleepiness severe enough to impair driving safety
- Mood changes suggesting depression or anxiety as an underlying driver
- Reliance on alcohol as a sleep aid (common and counterproductive)
- Use of over-the-counter sleep aids becoming habitual
- Insomnia associated with a new or worsening medical condition
- Suicidal ideation, which has a documented association with chronic insomnia
Assessment: Claude covered underlying cause investigation most thoroughly. Med-PaLM 2 addressed sleep apnea screening and sleep study indications. GPT-4 mentioned some factors. Gemini’s coverage was inadequate.
When to See a Doctor
AI Is Reasonably Helpful For:
- Understanding the difference between acute and chronic insomnia
- Learning about CBT-I as the first-line treatment
- Understanding why sleeping pills are not the best long-term solution
- Learning behavioral strategies for sleep improvement
See a Doctor When:
- Insomnia persists beyond three months despite behavioral changes
- Daytime impairment is significant (work errors, driving safety concerns)
- You suspect sleep apnea or another sleep disorder
- Depression or anxiety is present alongside insomnia
- You are using alcohol or OTC sleep aids regularly
- You want a CBT-I referral or evaluation for a formal sleep study
Can AI Replace Your Doctor? What the Research Says
Key Takeaways
- All models identified chronic insomnia correctly, but their management guidance ranged from generic sleep hygiene (Gemini) to comprehensive CBT-I education (Claude).
- Claude scored highest by recognizing that the patient was already practicing good hygiene and elevating the discussion to underlying cause investigation and evidence-based treatment.
- CBT-I is the most important piece of information for a chronic insomnia patient, and only Claude and Med-PaLM 2 presented it as the clear first-line treatment per clinical guidelines.
- AI performs well for insomnia education because many of the behavioral interventions can be self-directed or pursued through digital CBT-I programs.
- The key safety boundary is ensuring that treatable underlying conditions (sleep apnea, depression, thyroid dysfunction) are not missed.
