Hypnosis is a trance-like mental state in which people experience increased attention, concentration, and suggestibility. While hypnosis is often described as a sleep-like state, it is better expressed as a state of focused attention , heightened suggestibility, and vivid fantasies. People in a hypnotic state often seem sleepy and zoned out, but in reality, they are in a state of hyper-awareness.

While there are many myths and misconceptions, hypnosis is a very real process that can be used as a therapeutic tool. Hypnosis has been shown to have medical and therapeutic benefits, most notably in the reduction of pain and anxiety.

It has even been suggested that hypnosis can reduce the symptoms of dementia. There are a few different ways that hypnosis can be delivered:. Why might a person decide to try hypnosis? In some cases, people might seek out hypnosis to help deal with chronic pain or to alleviate pain and anxiety caused by medical procedures such as surgery or childbirth. Hypnosis has also been used to help people with behavior changes such as quitting smoking, losing weight, or preventing bed-wetting.

What impact does hypnosis have? The experience of hypnosis can vary dramatically from one person to another. Some hypnotized individuals report feeling a sense of detachment or extreme relaxation during the hypnotic state while others even feel that their actions seem to occur outside of their conscious volition.

Other individuals may remain fully aware and able to carry out conversations while under hypnosis. Experiments by researcher Ernest Hilgard demonstrated how hypnosis can be used to dramatically alter perceptions. While non-hypnotized individuals had to remove their arm from the water after a few seconds due to the pain, the hypnotized individuals were able to leave their arms in the icy water for several minutes without experiencing pain.

While many people think that they cannot be hypnotized, research has shown that a large number of people are more hypnotizable than they believe.

Research suggests that:. If you are interested in being hypnotized, it is important to remember to approach the experience with an open mind. People who view hypnosis in a positive light tend to respond better. If you are interested in trying hypnotherapy, it is important to look for a professional who has credentials and experience in the use of hypnosis as a therapeutic tool. While there are many places that offer hypnosis training and certification, it may be helpful to look for a mental health professional who has been certified by the American Society of Clinical Hypnosis.

Their program is open to health professionals with a master's degree and requires 40 hours of approved workshop training, 20 hours of individual training, and two years of practice in clinical hypnosis. A classic example of this approach uses a technique known as posthypnotic amnesia PHA to model memory disorders such as functional amnesia , which involves a sudden memory loss typically due to some sort of psychological trauma rather than to brain damage or disease.

Now a new study shows that this hypnotic state actually influences brain activity associated with memory. 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. Researchers have used PHA as a laboratory analogue of functional amnesia because these conditions share several similar features. Case reports of functional amnesia, for instance, describe men and women who, following a traumatic experience such as a violent sexual assault or the death of a loved one, are unable to remember part or all of their personal past.

In contrast, explicit memories are those we consciously have access to, such as remembering a childhood birthday or what you had for dinner last night. And, as suddenly as they lost their memories, they can just as suddenly recover them. Forgetting in the Brain But for the comparison between PHA and functional amnesia to be most meaningful, we need to know that they share underlying processes.

One way to test this is to identify the brain activity patterns associated with PHA. In a groundbreaking study published in Neuron , neuroscientist Avi Mendelsohn and colleagues at the Weizmann Institute in Israel did just that using functional magnetic resonance imaging fMRI. They carefully selected 25 people to participate in their experiment.

In the Study session of their experiment, participants watched a minute movie. One week later, in the Test session, participants returned to the laboratory and were hypnotized while they lay within the fMRI scanner. During hypnosis, people in both the PHA and non-PHA groups received a suggestion to forget the movie until they heard a specific cancellation cue. For Test 2, participants were asked the same 60 recognition questions, but first they heard the cue to cancel PHA.

So Test 1 measured memory performance and brain activity while the PHA suggestion was in effect and Test 2 measured memory performance and brain activity after it was cancelled. But in Test 2, after the suggestion was cancelled, this memory loss was reversed. Somewhat surprisingly, however, the suggestion to forget was selective in its impact. Although people in the PHA group had difficulty remembering the content of the movie following the forget suggestion, they had no difficulty remembering the context in which they saw the movie.

Can Hypnosis Improve Memory? Memories are created in the short term, and then they are stored in the long term if they are recalled often enough. One of the most common reasons for forgetting a fact or an event has to do with allowing it to slip from the short-term memory before your brain has a chance to consolidate it. How does hypnosis affect memory? It gives you an environment in which to relax and allow your memory to work properly again. A useful way of seeing how does hypnosis affect memory involves its focus on sensory modalities.

Smell is a particularly good stimulus for memory, and a skilled hypnotist will use this sense among the other main 5 to help you remember. Hypnotism is very commonly used for a wide variety of different purposes from memory retrieval to the visualization of success.
