Since a key focus of meditation is to induce a tranquil state of mind, it is perhaps no surprise that researchers have found the practice yields brain benefits.
Earlier this year, a study reported by Medical News Today suggested meditation may reduce brain aging.
The study of 100 individuals aged 24-77 – of whom 50 were meditators – found that those who engaged in meditating showed reduced gray matter loss in certain brain regions, compared with non-meditators.
Another study, published in the Journal of Alternative and Complementary Medicine in 2012, suggested that mantra-based meditation – a form of concentrative meditation in which a word, phrase or sound is repeated to prevent distracting thoughts – mayhelp older individuals with memory loss.
The researchers, from Thomas Jefferson University Hospital in Philadelphia, PA, found that 12 minutes of mantra-based meditation daily for 8 weeks increased cerebral blood flow to the prefrontal, superior frontal and superior parietal cortices of 12 older adults with memory problems and improved their cognitive function.
While it remains unclear exactly how meditation affects the brain, researchers are getting closer to finding out.
Last year, MNT reported on a study in which researchers found individuals showed higher brain activity in brain regions associated with processing self-related thoughts, feelings and memory retrieval when they practiced Acem meditation – a form of open-awareness meditation – compared with when they were resting.
However, when the same participants practiced concentrative meditation, their brain activity in these regions was the same as when they were resting. This, according to the researchers, suggests that open-awareness meditation allows greater processing of memory and emotions than concentrative meditation.
Chronic pain – defined as pain lasting at least 12 weeks – is one of the leading causes of disability in the US, affecting around 100 million Americans. The most common types of pain include low back pain, severe headache or migraine and neck pain.
While medications such as opioids are commonly used to treat pain, studies have increasingly suggested meditation could be an effective pain reliever.
Last year, a study led by the Wake Forest Baptist Medical Center in Winston-Salem, NC, found an 8-week mindfulness-based meditation program that incorporated yoga reduced the frequency and severity of migraines; those who completed the program had 1.4 fewer migraines a month.
More recently, a study published in the Journal of Neuroscience last month – also by researchers from Wake Forest Baptist Medical Center – found that individuals who engaged in mindfulness meditation showed a 44% reduction in emotional response to physical pain and a 27% reduction in pain intensity.
Further investigation using brain imaging revealed that mindfulness meditation reduced participants’ pain by activating the orbitofrontal and anterior cingulate cortex brain regions, which play a role in self-control of pain.
“Based on our findings, we believe that as little as four 20-minute daily sessions of mindfulness meditation could enhance pain treatment in a clinical setting,” said lead author Fadel Zeidan.
With today’s hectic lifestyles, it is no wonder so many of us have problems sleeping; around 50-70 million people in the US have some form of sleep disorder. But could meditation help? Some researchers think so.
In February this year, a study reported by MNT found that mindfulness meditation improved the sleep quality of older adults; more than half of American adults aged 55 and older have problems sleeping.
Published in JAMA Internal Medicine, the study revealed mindfulness meditation 2 hours a week for 6 weeks reduced Pittsburgh Sleep Quality Index (PSQI) scores among the adults from 10.2 to 7.4, compared with a reduction from 10.2 to only 9.1 for those who completed a sleep hygiene education program.
And last year, a study by researchers from Canada found mindfulness-based meditation improved both mood and sleep quality for teenage cancer patients.
