Meditation Helps Immune System

Posting Date: 08/14/2003

Comment: This certainly is positive information for those of you who meditate. Yet we don't know if just relaxing for an hour a day listening to your favorite music would have the same effect. We have found that stress reduces the power of your immune system against infections so perhaps meditation worked in this study by reducing stress. It would be interesting to see what would have happened if they compared another stress reducing technique to meditation. The control group was just other employees who did nothing.

Alterations in Brain and Immune Function Produced by Mindfulness Meditation

OBJECTIVE: The underlying changes in biological processes that are associated with reported changes in mental and physical health in response to meditation have not been systematically explored. We performed a randomized, controlled study on the effects on brain and immune function of a well-known and widely used 8-week clinical training program in mindfulness meditation applied in a work environment with healthy employees.

METHODS: We measured brain electrical activity before and immediately after, and then 4 months after an 8-week training program in mindfulness meditation. Twenty-five subjects were tested in the meditation group. A wait-list control group (N = 16) was tested at the same points in time as the meditators. At the end of the 8-week period, subjects in both groups were vaccinated with influenza vaccine.

RESULTS: We report for the first time significant increases in left-sided anterior activation, a pattern previously associated with positive affect, in the meditators compared with the nonmeditators. We also found significant increases in antibody titers to influenza vaccine among subjects in the meditation compared with those in the wait-list control group. Finally, the magnitude of increase in left-sided activation predicted the magnitude of antibody titer rise to the vaccine.
