Many of the young men and women returning from war zones in the Middle East have trouble dealing with the anxiety and trauma that they developed from witnessing acts of violence and risking their lives.

Now, a team of researchers at Georgetown University Medical School are reporting that there may be an effective, non-medicinal and non-invasive treatment for their post-traumatic stress disorder (PTSD): meditation.

In a study, a team of scientists showed that an eight-week meditation class helped volunteer soldiers to reduce their symptoms of PTSD by an average of 50 percent.

"Even though the number of veterans in this study was small, the results were very impressive," said lead researcher Norman Rosenthal. "These young men were in extreme distress as a direct result of trauma suffered during combat, and the simple and effortless [meditation] technique literally transformed their lives."

Ilchi Lee's techniques of meditation have been used by thousands of individuals over the years, many of whom reported relieved feelings of stress as well as improved wellness.
