Looking to lower your blood pressure and improve your balance? Try walking . . . on cobblestones. Researchers at the Oregon Research Institute first observed Chinese walking over traditional cobblestone paths for health reasons, and decided to build up a study around the phenomenon to see if they could scientifically measure its medical benefits. The findings were reported in a recent issue of the Journal of the American Geriatrics Society.

The study involved 108 participants, all over the age of 60. One group walked for half an hour a day on a simulated cobblestone mat. Some wore socks, others were barefoot. The second group just walked on normal ground for an hour three times a week. The study lasted for four months, after which both groups claimed to feel better. Those who walked on the cobblestones also showed significant improvements in balance, mobility and blood pressure. The biggest surprise for researchers was how quickly these improvements occurred.

Why was this effective? Practitioners of cobblestone walking in China claim that the cobblestones stimulate “acupoints” (think acupuncture) in the soles of the feet. Researchers in this study believe that the answer lies more with the way we maintain balance. We do this using two complex methods called the vestibular system (residing in the inner ear) and the somatosensory system (connecting the skin and muscles). When we walk normally, the somatosensory system makes up about 70 percent of our balance control. On cobblestones or other uneven surfaces, that number is switched in favor of the vestibular system.

As we age, we lose receptors in our vestibular system, causing it to diminish. This study concluded that, by forcing the vestibular system to work on a regular basis, it was improved in seniors to the point where it not only gave a boost to balance, but also helped to lower blood pressure.
