Scientific evidence for the effectiveness of hypnotherapy

Hypnotherapy, a therapeutic technique that utilises hypnosis to induce a state of focused attention and heightened suggestibility, has been a subject of fascination and scepticism for centuries.


While some view it as a mystical or pseudoscientific practice, modern research has shed light on its potential effectiveness for various psychological and medical conditions. In this article, I will explore the scientific evidence supporting the use of hypnotherapy as a legitimate and valuable therapeutic tool.

Understanding hypnotherapy

Hypnotherapy involves guiding an individual into a trance-like state, often referred to as hypnosis, where they become more open to suggestions and focused on the hypnotist's instructions. Contrary to popular belief, hypnosis is not a state of unconsciousness or loss of control; instead, it is an altered state of consciousness in which the individual remains fully aware of their surroundings but experiences increased receptivity to positive suggestions and imagery. In fact, the ‘state’ of hypnosis is something people experience spontaneously when daydreaming, lost in thought or lost in a moment of nature's beauty.

The science behind hypnosis

The scientific understanding of hypnosis has evolved over the years, and researchers have made significant strides in unravelling its neural mechanisms. Functional magnetic resonance imaging (FMRI) and electroencephalogram (EEG) studies have shown that hypnosis involves alterations in brain activity and connectivity, particularly in regions responsible for attention, perception, and emotional processing.

During hypnosis, the brain enters a state of heightened focused attention and reduced peripheral awareness. This altered state allows individuals to bypass their critical conscious mind, making them more open to suggestion and behavioural changes. Additionally, hypnosis has been found to influence the release of neurotransmitters and neurohormones, such as endorphins and dopamine, contributing to its potential therapeutic effects.

Scientific evidence for its effectiveness

1. Pain management

Numerous studies have demonstrated the efficacy of hypnotherapy in managing various types of pain, including chronic pain, childbirth pain, and even pain associated with medical procedures. For instance, a meta-analysis published in the Journal of Pain found that hypnosis was significantly effective in reducing pain intensity and medication usage in chronic pain patients.
2. Smoking cessation

Hypnotherapy has been used as a smoking cessation aid with promising results. A study published in the International Journal of Clinical and Experimental Hypnosis revealed that individuals who received hypnotherapy for smoking cessation were more likely to remain smoke-free compared to those who attempted to quit without it.
3. Anxiety and stress reduction

Hypnotherapy has shown potential in alleviating anxiety and stress-related disorders. Research published in the American Journal of Clinical Hypnosis reported significant reductions in anxiety and improved coping mechanisms among participants who underwent hypnotherapy.
4. Weight loss and eating problems

In the realm of weight management, hypnotherapy has been investigated as a potential tool to aid in weight loss. Studies have found that hypnotherapy, when used in conjunction with other interventions, can lead to sustained weight loss and positive changes in eating behaviours.
5. Sleep disorders

Hypnosis has been studied for its effectiveness in managing various sleep disorders, such as insomnia. Research published in the Journal of Clinical Sleep Medicine showed that hypnosis improved sleep quality and decreased the time it took participants to fall asleep.
 6. Irritable bowel syndrome (IBS)

Studies have explored hypnotherapy as a treatment for irritable bowel syndrome, a functional gastrointestinal disorder. Results have indicated that hypnotherapy can significantly reduce symptoms and improve the quality of life for individuals with IBS.
7. Post-traumatic stress disorder (PTSD)

Hypnotherapy has been considered a complementary treatment for PTSD. Studies have suggested that hypnosis can help alleviate PTSD symptoms and aid in trauma processing.

The role of hypnotherapists and professional associations

Hypnotherapists play a crucial role in applying evidence-based techniques and tailoring treatment plans to suit individual needs. Ethical hypnotherapists are trained professionals who adhere to ethical guidelines and maintain confidentiality.

Several professional associations, such as the American Society of Clinical Hypnosis (ASCH) and the General Hypnotherapy Standards Council (GHSC), Complimentary & Natural Healthcare Council (CNHC) promote research, education, and the responsible practice of hypnotherapy. These organisations ensure that practitioners stay up-to-date with the latest research and adhere to high standards of practice.

While hypnotherapy may have once been regarded with scepticism, scientific evidence has increasingly shown its effectiveness in addressing a wide range of psychological and medical conditions. From pain management and smoking cessation to anxiety reduction and weight loss, hypnotherapy has emerged as a legitimate therapeutic tool. As research continues to shed light on the underlying mechanisms and potential applications of hypnosis, it is essential to recognise the importance of qualified and ethical hypnotherapists who can harness its power to bring about positive change in the lives of those seeking relief from various issues.
