HOW WILL A MINDFULNESS PRACTICE BENEFIT ME?
It’s a piece of advice yogis have given for thousands of years: take a deep breath and relax. Watch the tension melt from your muscles and all your niggling worries vanish. Somehow we all know that relaxation is good for us.
Now the hard science has caught up: a recently published comprehensive scientific study shows that deep relaxation changes our bodies on a genetic level. What researchers at Harvard Medical School discovered is that, in long-term practitioners of relaxation methods such as yoga and meditation, far more ”disease-fighting genes” were active, compared to those who practiced no form of relaxation.
In particular, they found genes that protect from disorders such as pain, infertility, high blood pressure and even rheumatoid arthritis were switched on. The changes, say the researchers, were induced by what they call ”the relaxation effect”, a phenomenon that could be just as powerful as any medical drug but without the side effects. ”We found a range of disease-fighting genes were active in the relaxation practitioners that were not active in the control group,” Dr Herbert Benson, associate professor of medicine at Harvard Medical School, who led the research, says. The good news for the control group with the less-healthy genes is that the research didn’t stop there.
The experiment, which showed just how responsive genes are to behavior, mood and environment, revealed that genes can switch on, just as easily as they switch off. ”Harvard researchers asked the control group to start practicing relaxation methods every day,” says Jake Toby, hypnotherapist at London’s BodyMind Medicine Centre, who teaches clients how to induce the relaxation effect. ”After two months, their bodies began to change: the genes that help fight inflammation, kill diseased cells and protect the body from cancer all began to switch on.”
More encouraging still, the benefits of the relaxation effect were found to increase with regular practice: the more people practiced relaxation methods such as meditation or deep breathing, the greater their chances of remaining free of arthritis and joint pain with stronger immunity, healthier hormone levels and lower blood pressure. Benson believes the research is pivotal because it shows how a person’s state of mind affects the body on a physical and genetic level. It might also explain why relaxation induced by meditation or repetitive mantras is considered to be a powerful remedy in traditions such as Ayurveda in India or Tibetan medicine.
But just how can relaxation have such wide-ranging and powerful effects? Research has described the negative effects of stress on the body. Linked to the release of the stress-hormones adrenalin and cortisol, stress raises the heart rate and blood pressure, weakens immunity and lowers fertility. By contrast, the state of relaxation is linked to higher levels of feel-good chemicals such as serotonin and to the growth hormone which repairs cells and tissue. Indeed, studies show that relaxation has virtually the opposite effect, lowering heart rate, boosting immunity and enabling the body to thrive.
”On a biological level, stress is linked to fight-flight and danger,” Dr Jane Flemming, a London GP, says. ”In survival mode, heart rate rises and blood pressure shoots up. Meanwhile muscles, preparing for danger, contract and tighten. And non-essential functions such as immunity and digestion go by the wayside.” Relaxation, on the other hand, is a state of rest, enjoyment and physical renewal. Free of danger, muscles can relax and food can be digested. The heart can slow and blood circulation flows freely to the body’s tissues, feeding it with nutrients and oxygen. This restful state is good for fertility, as the body is able to conserve the resources it needs to generate new life.
