Changing Our DNA through Mind Control?
A study finds meditating cancer patients are able to affect the makeup of their DNA
Telomeres are stretches of DNA that cap our chromosomes and help prevent chromosomal deterioration — biology professors often liken them to the plastic tips on shoelaces. Shortened telomeres aren’t known to cause a specific disease per se, but they do whither with age and are shorter in people with cancer, diabetes, heart disease and high stress levels. We want our telomeres intact.
In Carlson’s study distressed breast cancer survivors were divided into three groups. The first group was randomly assigned to an 8-week cancer recovery program consisting of mindfulness meditation and yoga; the second to 12-weeks of group therapy in which they shared difficult emotions and fostered social support; and the third was a control group, receiving just a 6-hour stress management course. A total of 88 women completed the study and had their blood analyzed for telomere length before and after the interventions. Telomeres were maintained in both treatment groups but shortened in controls.
