Effects of a bereavement intervention program in middle-aged widows in Korea.

Dan-jeon is a meditative practice composed of both breathing and stretching exercises causing life energies to circulate blood throughout the body. Following a bereavement intervention program composed of Dan-jeon breathing sessions, a self-help group activity, and a health check, an experimental group showed significantly greater decrements in grief levels and symptoms of stress over a control group who received only a health check. Among the participants, there were no significant differences in immune response, percentages of T lymphocytes, helper T lymphocytes (Th), suppressor T lymphocytes (Ts), B lymphocytes, natural killer cells, monocytes, and Th:Ts ratios.
