Hypnoimagery & Guided Meditation
How Effective Is Imagery? Clinical Studies on the Effectiveness of
Imagery
has found it very effective for the treatment of stress.
Imagery is at the center of relaxation techniques designed to release
brain chemicals that act as your body's natural brain tranquilizers,
lowering blood pressure, heart rate, and anxiety levels. By and large,
researchers find that these techniques work. Because imagery relaxes the
body, doctors specializing in imagery often recommend it for
stress-related conditions such as headaches, chronic pain in the neck
and back, high blood pressure, spastic colon, and cramping from
premenstrual syndrome.
Researchers at Ohio State University in Columbus, Ohio found that
people with cancer who used imagery while receiving chemotherapy felt
more relaxed, better prepared for their treatment and more positive
about care than those who didn't use the technique.
Several studies suggest that imagery can also boost your immunity.
Danish researchers found increased natural killer cell activity among
ten college students who imagined that their immune systems were
becoming very effective. Natural killer cells are an important part of
the immune system because they can recognize and destroy virus-infected
cells, tumor cells and other invaders.
In another small study, researchers at Pennsylvania State University
in University Park, Pa and Case Western Reserve University School of
Medicine in Cleveland, Ohio found that seven people who suffered from
recurrent canker sores in their mouths significantly reduced the
frequency of their outbreaks after they began visualizing that the sores
were bathed in a soothing coating of white blood cells.
Imagery can also help alter menstrual cycles and relieve symptoms of
premenstrual syndrome. In a preliminary study, researchers at
Massachusetts General Hospital in Boston found that 12 of 15 women, ages
21 to 40, who used imagery for three months lengthened their monthly
menstrual cycles by an average of nearly four days and slashed their
perceived levels of premenstrual distress in half. They also reported
fewer mood swings.
At the University of South Florida in Tampa, researchers asked 19 men
and
women, ages 56 to 75, who had chronic bronchitis and emphysema to rate
their levels of anxiety, depression, fatigue and discomfort before and
after they began using imagery. The researchers concluded that imagery
significantly improved the overall quality of these people's lives.
A study at Yale demonstrated that patients suffering from severe
depression were helped by imagining scenes in which they were praised by
people they admired- a clear boost to their self-esteem.
Visualization and other relaxation methods may produce significant
benefits, often by helping to ease pain and lift depression. Research is
continuing to determine whether even more spectacular results can be
achieved.
A controlled study of fifty-five women examined the effects of
imagery and relaxation on breast milk production in mothers of infants
in a neonatal intensive care unit. They received a twenty-minute
audiotape of progressive relaxation followed by guided imagery of
pleasant surroundings, milk flowing in the breasts, and the baby's warm
skin against theirs. They produced more than twice as much milk as
compared to those receiving only routine care.
In another study, a group of metastatic cancer patients using daily
imagery for a year achieved significant improvements in NK cell activity
and several other measures of immune functioning.
At Michigan State University, researchers found that students could
use guided imagery to improve the functioning of certain white cells
called neutrophils, important immune cells in defense against bacterial
and fungal infection. They could also decrease, but not increase, white
cell counts. At one point in the study, a form of imagery intended to
increase neutrophil count unexpectedly caused a drop instead.
Subsequently, students were taught imagery explicitly intended to keep
the neutrophil count steady, while increasing their effectiveness. Both
of these goals were achieved.
Other studies have shown that imagery can lower blood pressure, slow
heart rate and help treat insomnia, obesity and phobias.
