"For one thing, meditation lengthens telomeres, the ends of chromosomes that contain genes," says Kessler. "So when you have a genetic illness, to have the disease, you have to express that gene. For certain illnesses, the longer the telomeres are, the less likely you are to express it. For people who have high blood pressure, up to 80 percent of what we call central hypertension can be regulated and controlled by meditation. Anxiety attacks, panic attacks, autoimmune diseases like lupus, asthma — all can be helped by meditation. It's not a matter of mind over matter. It's a matter of the mind does matter. The body listens to the mind."
