Hypnosis is a powerful tool to help clients overcome challenging issues such as anxiety, phobias, pain management, hot flashes and more. Hypnosis is also a way to help let go of addictions like smoking, overeating and gambling. In and of itself, hypnosis is not a therapy, but it can be used in conjunction with therapy to empower and encourage the person receiving it to make positive change. Some people are more susceptible to hypnosis and will benefit more from hypnotherapy than others.
A typical hypnotherapy session has the patient seated comfortably with their feet on the floor and palms on their lap. Of course, the patient could choose to lie down if that option is available and if that will meet the patient's expectation of hypnosis. The therapist can even set the stage for a favorable outcome by asking questions like, "Would you prefer to undergo hypnosis in this chair or on the sofa?" Once patients make the choice, they are in effect agreeing to undergo hypnosis. Depending on the approach used by the therapist, the next events can vary, but generally will involve some form of relaxing the patient. Suggestions will lead the patient to an increasingly relaxed state. The therapist may wish to confirm the depth of trance by performing tests with the patient. For example, the therapist may suggest that when the eyes close that they will become locked and cannot be opened. The therapist then checks for this by having patients try to open their eyes. Following a successful trial showing the patient's inability to open the eyes, the therapist might then further relax them by using deepening techniques. Deepening techniques will vary for each patient and depend largely on whether the patient represents information through auditory, visual, or kinesthetic means. If the patient is more affected by auditory suggestions, the therapist would use comments such as "You hear the gentle patter of rain on the roof;" or, "The sound of the ocean waves allow you to relax more and more." For the visual person, the therapist might use statements such as, "You see the beautiful placid lake, with trees bending slightly with the breeze." Finally, with the kinesthetic person phrases such as, "You feel the warm sun and gentle breeze on your skin," could be used. It is important for the therapist to know if the patient has difficulty with the idea of floating or descending because these are sometimes used to enhance the experience for the patient. However, if the patient has a fear of heights or develops a feeling of oppression with the thought of traveling downward and going deeper and deeper, suggestions implying the unwanted or feared phenomenon will not be taken and can thwart the attempt.
In order for a hypnotherapist to convey positive suggestions for change, the patient must be in a receptive state. The state is called trance and the method of achieving a trance is through induction. Induction techniques are many and varied and involve the therapist offering suggestions that the patient follows. The formerly common "your eyes are getting heavy" suggestion may still exist, but other more reliable and acceptable (by the patient) forms of induction have come to the forefront. The artful hypnotherapist is always aware of the present condition of the patient and uses this information to lead him/her down the path of induction. In its lighter stages, trance can be noted by the relaxation of muscles. At this point, hands can levitate when given the suggestion, and paresthesia, a feeling of numbness, can be induced. In a medium trance, a patient can be led to experience partial or complete amnesia , or failure to recall events of the induction after the fact. A deep trance opens the patient to powerful auditory, visual, or kinesthetic experiences. The phenomenon of time distortion is experienced most profoundly at this level. Patients may believe they have been away briefly, and may react with disbelief when told they were away much longer. Although some work can be done in lighter states of trance, the best circumstance for implementing change is when the patient reaches a deep trance state. At this level, the patient is focused inwardly and is more receptive to positive suggestions for change. This is also the point at which the therapist can invoke posthypnotic suggestions, or instructions given to the patient so he/she will perform some act or experience some particular sensation following awakening from the trance. For example, these suggestions, if accepted by the patient, can be formed to make foods taste bad, cigarettes taste bad, delay impulses, curb hunger, or eliminate pain. However, it should be noted that posthypnotic suggestions given to a person, which run counter to the person's value system or are not something they are likely to do under ordinary circumstances, will not be accepted and therefore not implemented.
High hypnotizable people with PHA typically show impaired explicit memory, or difficulty consciously recalling events or material targeted by the suggestion, and a dissociation between implicit and explicit memory, so that even though they can’t recall the forgotten information it continues to influence their behavior, thoughts and actions. The forgetting is reversible—when the suggestion is cancelled, their memories come flooding back. These last two features—the dissociation and reversibility—confirm that PHA is not the result of poor encoding of the memories or of normal forgetting, because the memories return as soon as PHA is cancelled. Rather, PHA reflects a temporary inability to retrieve information that is safely stored in memory. That makes it a useful tool for research.
People have been pondering and arguing over hypnosis for more than 200 years, but science has yet to fully explain how it actually happens. We see what a person does under hypnosis, but it isn't clear why he or she does it. This puzzle is really a small piece in a much bigger puzzle: how the human mind works. It's unlikely that scientists will arrive at a definitive explanation of the mind in the foreseeable future, so it's a good bet hypnosis will remain something of a mystery as well.
Hypnosis is first and foremost a self-accepted journey away from the reality of the moment. Although the trance state is often referred to as if the patient is asleep, nothing could be further from the truth. The patient is fully awake at all times. The hypnotic subject is simply in a heightened, more receptive state of mind. This fact is proven with inductions called open-eye techniques, where the patient keeps his/her eyes open during the hypnotherapy. Full and deep trance is still achievable.
Barber et al. noted that similar factors appeared to mediate the response both to hypnotism and to cognitive behavioural therapy, in particular systematic desensitization. Hence, research and clinical practice inspired by their interpretation has led to growing interest in the relationship between hypnotherapy and cognitive behavioural therapy.:105
