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 comprehensive scientific study showing that deep relaxation changes our bodies on a genetic level has just been published. 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 practised 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 behaviour, mood and environment, revealed that genes can switch on, just as easily as they switch off. ”Harvard researchers asked the control group to start practising 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 practised 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.
While relaxation techniques can be very different, their biological effects are essentially similar. ”When you relax, the parasympathetic nervous system switches on. That is linked to better digestion, memory and immunity, among other things,” Toby says. ”As long as you relax deeply, you’ll reap the rewards.” But, he warns, deep relaxation isn’t the sort of switching off you do relaxing with a cup of tea or lounging on the sofa.
”What you’re looking for is a state of deep relaxation where tension is released from the body on a physical level and your mind completely switches off,” he says. ”The effect won’t be achieved by lounging round in an everyday way, nor can you force yourself to relax. You can only really achieve it by learning a specific technique such as self-hypnosis, guided imagery or meditation.”
The relaxation effect, however, may not be as pronounced on everyone. ”Some people are more susceptible to relaxation methods than others,” says Joan Borysenko, director of a relaxation program for outpatients at Beth Israel Deaconess Medical Centre in Boston. ”Through relaxation, we find some people experience a little improvement, others a lot. And there are a few whose lives turn around totally.”
Most importantly, Dru Meditation will help you find that still place, with its sense of fullness, achievement and its deep healing properties, which only yoga and meditation can bring.
Dru comes from the sanskrit word Dhruva which refers to the stillness that can be experienced in Dru Yoga and Meditation. In the stillness we are able to sit back from everything happening around us and see and act from a place of clarity and inner calm.
