Yes, and the body of evidence has grown significantly in recent years. Hypnosis has been studied in randomized controlled trials and large-scale meta-analyses across dozens of applications, with particularly strong findings in pain management, anxiety, depression, IBS, smoking cessation, and menopausal symptoms.
A landmark 2024 review published in Frontiers in Psychology examined 20 years of meta-analyses and confirmed hypnosis as an evidence-based approach. The American Psychological Association, the American Medical Association, and the British Medical Association have all formally recognized hypnosis as a legitimate tool. The North American Menopause Society even rates hypnosis at Level I (their highest evidence designation) for menopausal hot flashes.
Neuroscience is catching up, too. Recent brain imaging studies used EEG, fMRI, and MRS to confirm that hypnosis produces measurable, objective changes in brain activity and neurochemistry.
