In meditation research the news keeps getting better and better:
“Previous studies have reported changes to the brain while people practise [meditation, yoga and prayer] activities, but a new study shows for the first time that gene activity changes too. [...] “It’s not New Age nonsense,” says Herbert Benson of the Massachusetts General Hospital in Boston. He and his colleagues analysed the gene profiles of 26 volunteers – none of whom regularly meditate – before teaching them a relaxation routine lasting 10 to 20 minutes. It included reciting words, breathing exercises and attempts to exclude everyday thought.”
An 8-week course of meditation of this kind resulted in a change of gene profile:
“The boosted genes had three main beneficial effects: improving the efficiency of mitochondria, the powerhouse of cells; boosting insulin production, which improves control of blood sugar; and preventing the depletion of telomeres, caps on chromosomes that help to keep DNA stable and so prevent cells wearing out and ageing.”
Plus there was a decrease in the activity of “a master gene called NF-kappaB, which triggers chronic inflammation leading to diseases including high blood pressure, heart disease, inflammatory bowel disease and some cancers.”
Furthermore: “by taking blood immediately after before and after performing the technique on a single day, researchers also showed that the gene changes happened within minutes.”
