Scientists are starting to understand the mechanisms behind a mind-body technique that produces significant stress reduction after just five days of practice.

The technique in question is called integrative body-mind training (IBMT) and was adapted in the 1990s from traditional Chinese medicine.

In late 2007, researchers from the University of Oregon (UO) observed that practicing IBMT prior to a math test led to low levels of the stress hormone cortisol among Chinese students.

The experimental group also showed lower levels of anxiety, depression, anger and fatigue than students in a control group.

The scientists theorize IBMT delivers such dramatic results by altering blood flow and electrical activity in the brain, breathing quality and even skin conductance.

Last month, a new Chinese-American study was published which sought to define brain and physiological changes triggered by IBMT.

“We were able to show that the training improved the connection between a central nervous system structure, the anterior cingulate, and the parasympathetic part of the autonomic nervous system to help put a person into a more bodily state,” says UO psychologist Michael Posner, who participated in the research.

“The results seem to show integration – a connectivity of brain and body,” he adds.

Health practitioners have also recommended nutritional supplements containing extracts of chamomile, valerian and passionflower to help combat symptoms of stress.
