7 Health Benefits of Meditation

"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."
