To what extent should we be using food to maintain our health and heal our body? According to nutritionist and Kripalu Healthy Living faculty member John Bagnulo, PhD, MPH, “Food—not supplements—should be where you get 98 percent of your nutrients.” Like John, Kathie Madonna Swift, MS, RD, LDN, an integrative clinical nutritionist who teaches at […]
The benefits of meditation for seniors
In a recent study, nearly 70 percent of people over the age of 60 reported experiencing loneliness, a risk factor for functional decline and early death. But those who took part in an eight-week meditation program reduced those feelings of loneliness—and gave their immune systems a boost as well. The study, conducted by researchers at the University of California Los Angeles, is published in this month’sissue of the journal Brain, Behavior and Immunity.
Yoga has long been known to help ease depression and loneliness by raising concentrations of gamma-amminobutyric acid (GABA), the neurotransmitter responsible for regulating the nervous system. High levels of GABA have a calming effect. Of course, loneliness isn’t just an emotional issue; it’s a form of stress that can have physical manifestations as well, says Randal Williams, a Kripalu Yoga instructor and teacher trainer, who isn’t surprised by the study’s findings. “When I was a child I used to go to religious services with my grandmother,” says Randal. “This was her way of connecting with others. Whether it is to do yoga or meditate or walk or sit and share tea, getting together with others has a positive impact.”
Aging Gracefully Through Meditation
Meditation has long been believed to be a win-win proposition, carrying certain psychological benefits with zero risk or cost. People who meditate regularly report lower levels of stress, improvements in concentration and memory, and slower reactivity (no more road rage!). The mental relaxation produced by meditation can have physiological benefits, too, in the same way we know that a calmer emotional state is good for our physical body. But a few new studies reveal that the practice may have profound effects on actual brain development—something traditionally believed to peak in our 20s and then begin to decline.
Researchers at the Laboratory of Neuroimaging at UCLA have spent years studying how meditation may affect neuroplasticity, the ability of the brain to make physiological changes. In a recent study published in the journal Frontiers in Human Neuroscience, the lab reported finding that long-term meditators had brain function that not only did not decline as they aged, but improved, thanks to an increase in brain gyrification—activity that happens in the cerebral cortex, or the outermost part of the brain. The lab also determined that the brains of dedicated meditators have more gray matter, which affects the brain’s ability to process information, and white matter, which helps a person communicate clearly.
