Hypnosis is a state of mind during which a
person's consciousness is altered and distractions blocked. It resembles
sleep, but people under hypnosis are still able to concentrate intently
on a memory, a particular sensation, or any other issue. The hypnotized
person is alert, yet relaxed.
People under hypnosis have been shown to decrease their heart rate,
alter body temperature, and reduce blood flow to particular areas
of the body.
Through hypnosis, some people can learn to control habits such as
smoking or bedwetting, and reduce pain, stress, and anxiety.
About nine out of ten people can be hypnotized, at least to some
degree. Many can be trained to hypnotize themselves and thus, for
example, manage their own pain. Hypnotism will not work if the person
does not want to be hypnotized. Children are better hypnosis candidates
than adults, probably because hypnotism requires the trust, imagination,
and open-mindedness which most children have.
Hypnotism as a useful tool in modern medicine began with Franz Mesmer,
an Austrian doctor who believed that illness was caused by imbalances
in the body's magnetic forces. He believed he could restore magnetic
balance through the use of soothing words and quieting gestures.
He called it "Mesmerism." Today, to be "mesmerized"
means to be hypnotized, charmed, or captivated.
Mesmer's original idea of achieving magnetic balance through Mesmerism
has long been discarded as incorrect. However, the value of hypnotism
in producing certain health benefits is widely accepted and often
used.
Hypnotherapy evokes a state of deep relaxation.
It can help divert a person's attention from negative stimuli such
as pain, and it increases the ability to respond to suggestion.
Hypnosis does not cause a person to lose control. In fact, the purpose
of hypnosis is to allow one to gain control over personal behavior.
This is brought about by intense concentration in a relaxed state.
Studies at Stanford University produced important information about
how hypnosis might work. Researchers found that hypnotized subjects
could suppress or stop their brains' electrical response to a picture
by imagining that they did not see it. This ability was previously
thought to be involuntary and not under the individual's control.
This ability to block a natural response through intense concentration
makes hypnotism a good pain reliever for dental surgery and painful
medical experiences. "Spinal anesthesia illusion" uses
hypnotherapy to control pain during surgery. The "illusion"
of external anesthesia actually blocks the pain. Hypnosis can block
pain even under very dramatic circumstances such as open heart surgery.
However, hypnosis is not a cure-all. It does not eliminate all behavior
problems or addictive disorders. It cannot cure serious disease.
Hypnosis can help in certain situations. Among
people with a proven ability to become hypnotized, it can relieve
pain, including cancer pain. It helps some people go through dental
drilling comfortably. It has been used successfully as a sedative
during childbirth and to treat the pain of migraine headaches.
Hypnosis has helped some smokers stay off tobacco for six months
or longer. The success rate for hypnosis in smoking cessation is
about equal to that of other methods used today. It can also help
calm problems of anxiety, depression, and a variety of phobias.
Hypnosis has helped many people overcome their fear of flying.
Cancer patients may consider hypnotherapy as a means of reducing
pain, promoting relaxation, and reducing stress.
Like other complementary therapies, hypnosis may be used in relieving
certain symptoms of cancer and side effects of cancer treatment.
Hypnosis should not be expected to slow or reverse growth or spread
of cancer.
