Hypnosis shows promise for improving sleep, with over half of reviewed studies reporting benefits. While generally safe, more high-quality research is needed to confirm its effectiveness for sleep problems.
Area of Science:
- Sleep Medicine
- Psychology
- Complementary Therapies
Background:
- Sleep improvement is crucial for overall health.
- Hypnosis is a safe, cost-effective intervention with potential health benefits.
- Research is increasingly exploring hypnosis for sleep-related conditions.
Purpose of the Study:
- To review the effects of hypnosis on sleep outcomes.
- To describe hypnotic procedures used in studies.
- To evaluate potential adverse effects of hypnosis.
Main Methods:
- Systematic review of studies published before January 2017.
- Inclusion of randomized controlled trials and prospective studies on adults with sleep problems.
- Qualitative analysis of 24 selected papers.
Main Results:
- 58.3% of studies reported positive effects of hypnosis on sleep.
- 12.5% reported mixed results, and 29.2% found no benefit.
- Hypnotic procedures were summarized, and adverse events were assessed, showing low incidence.
Conclusions:
- Hypnosis is a promising, low-risk treatment for sleep problems.
- Current evidence is limited by study quality, sample size, and focus.
- Further high-quality research is warranted to establish efficacy.

Sedatives and Hypnotics: Overview
Sedative-hypnotics are categorized into barbiturates, benzodiazepines (BZDs), and non-benzodiazepines or Z-drugs. These drugs work by suppressing central nervous system activity, and this suppression is dose-dependent. Older sedative medications, like barbiturates, follow a linear curve in...
Sedatives and Hypnotics Drugs: Miscellaneous Agents
Melatonin congeners like ramelteon (Rozerem) and tasimelteon (Hetlioz) selectively bind to melatonin receptors (MT1 and MT2) and thus mimic the actions of melatonin, a hormone that regulates sleep-wake cycles. Tasimelteon is primarily used for non-24-hour sleep-wake disorder, common in blind patients. They are also used to treat conditions like insomnia...
