Hypnosis for sleep: trend versus evidence

Hypnotherapy, according to the NHS, uses relaxation techniques to try to improve unhealthy habits or ways of thinking. (NHS — Herbal medicines and complementary therapies) In self-hypnosis, people learn to produce a relaxation response when prompted by an agreed cue — a phrase or a gesture, called a suggestion. (NCCIH — Relaxation Techniques) And research on hypnosis that also looks at sleep is growing, according to a review in the Journal of Clinical Sleep Medicine. (Chamine et al., J Clin Sleep Med 2018)

This article summarises what research has shown so far; it is not a diagnosis or a treatment.

What reviews of studies show

• A 2018 systematic review included 24 studies of adults with sleep problems or with conditions that disturb sleep. More than half reported a benefit for sleep; the rest found mixed results or no benefit. The authors call hypnosis promising, but the evidence is limited: few studies in people with sleep complaints, small samples and low methodological quality. (Chamine et al., J Clin Sleep Med 2018)
• A newer 2023 review, summarised by the US NCCIH, included 44 studies with 2,551 participants — healthy people and people with various conditions. Fewer than half of the studies showed a benefit for sleep; the rest found mixed results or no effect. In a group of 11 studies in people with sleep problems, where the suggestions targeted sleep directly, the results were more favourable. (NCCIH — Sleep Disorders and Complementary Health Approaches)
• The forms of hypnosis varied widely — from a 13-minute recording to eight one-hour sessions. (Chamine et al., J Clin Sleep Med 2018) None of the cited sources rates specific apps or recordings.

What this means for insomnia

• Relaxation techniques on their own don't seem especially promising for sleep, according to NCCIH, though they can be part of CBT-I. (NCCIH — Relaxation Techniques)
• The most strongly recommended treatment for insomnia remains, according to NCCIH, cognitive behavioural therapy for insomnia (CBT-I). (NCCIH — Sleep Disorders and Complementary Health Approaches)
• The UK NHS may offer hypnotherapy for irritable bowel syndrome (when other treatment has not worked) or for severe hiccups — insomnia is not on that list. (NHS — Herbal medicines and complementary therapies)

Safety

• According to NCCIH, hypnotherapy is generally considered safe when led by a qualified hypnotherapist with special training. (NCCIH — Sleep Disorders and Complementary Health Approaches)
• The 2018 review notes that in some people hypnosis may cause dizziness, confusion, unpleasant physical sensations, false memories or panic attacks; however, only a small share of studies monitored side effects. (Chamine et al., J Clin Sleep Med 2018)
• With relaxation techniques, people occasionally report more anxiety, intrusive thoughts or fear of losing control; rarely, symptoms got worse in people with epilepsy, certain psychiatric conditions, or a history of abuse or trauma. (NCCIH — Relaxation Techniques)
• According to the NHS, hypnotherapy may not be safe if you have schizophrenia or a history of psychosis, or epilepsy; always tell the therapist about your conditions and medicines. (NHS — Herbal medicines and complementary therapies)

When to see a doctor

• The NHS advises seeing a GP if changing your sleeping habits has not helped, you've had trouble sleeping for months, or insomnia is affecting your daily life. (NHS — Insomnia)
• If you have severe or long-lasting symptoms of any kind, see a doctor — hypnosis should not delay a check-up. (NCCIH — Relaxation Techniques)

Takeaways

1. Hypnosis and self-hypnosis work with relaxation and suggestion; research on sleep is growing.
2. Reviews look promising, but they rest on small studies of limited quality.
3. CBT-I remains the first-choice treatment for long-term insomnia.
4. With psychosis, epilepsy or past trauma, talk to a doctor first; the therapist should be trained.
5. Insomnia for months or a disrupted day → GP.

For some people hypnosis may be a pleasant way to relax — but it is not a magic off switch for sleep.
