New research suggests that yoga and meditation may not only give you a flexible body and inner peace but a combination of the two could also help improve cognitive function

The study, led by a team of researchers from UCLA and Australia's University of Adelaide, is the first to compare yoga and meditation against memory training, which has often been considered the best way to manage mild cognitive impairment. The team followed a group of 25 participants all aged 55 and over during a three-month course of either yoga and meditation or memory training. Participants had all shown signs of mild cognitive impairment, reporting problems with their memory such as easily misplacing things, or forgetting names, faces or appointments. Participants were split into two groups. Eleven participants attended memory enhancement training and practiced memory exercises daily, while the other 14 participants attended classes of Kundalini yoga and practiced 20 minutes of Kirtan Kriya meditation daily, which involves chanting, hand movements and visualization of light, and has already has been practiced in India for hundreds of years as a way to prevent cognitive decline in older adults. All participants received brain scans and completed memory tests at both the beginning and end of the three months. The results showed that although all participants demonstrated similar improvements in verbal memory skills, the skills that are needed for remembering names, it was the participants in the group who practiced yoga and meditation that showed better improvements in visual-spatial memory skills, which help with recalling locations and navigating. In addition, participants in the yoga and meditation group also showed bigger improvements in levels of depression, anxiety, coping skills and resilience to stress, all of which are especially important when coming to terms with the onset of cognitive impairment. Commenting on the significance of the results Harris Eyre, the study's lead author, said, "Historically and anecdotally, yoga has been thought to be beneficial in aging well, but this is the scientific demonstration of that benefit. We're converting historical wisdom into the high level of evidence required for doctors to recommend therapy to their patients." Senior author Helen Lavretsky added, "If you or your relatives are trying to improve your memory or offset the risk for developing memory loss or dementia, a regular practice of yoga and meditation could be a simple, safe and low-cost solution to improving your brain fitness."

Over the past decade, mindfulness meditation has been shown to improve a broad range of health and disease outcomes, such as slowing HIV progression and improving healthy aging

Yet, little is known about the brain changes that produce these beneficial health effects. New research from Carnegie Mellon University provides a window into the brain changes that link mindfulness meditation training with health in stressed adults. The study shows that mindfulness meditation training, compared to relaxation training, reduces Interleukin-6, an inflammatory health biomarker, in high-stress, unemployed community adults. The biological health-related benefits occur because mindfulness meditation training fundamentally alters brain network functional connectivity patterns and the brain changes statistically explain the improvements in inflammation. "We've now seen that mindfulness meditation training can reduce inflammatory biomarkers in several initial studies, and this new work sheds light into what mindfulness training is doing to the brain to produce these inflammatory health benefits," said David Creswell, lead author and associate professor of psychology in the Dietrich College of Humanities and Social Sciences. For the randomized controlled trial, 35 job-seeking, stressed adults were exposed to either an intensive three-day mindfulness meditation retreat program or a well-matched relaxation retreat program that did not have a mindfulness component. All participants completed a five-minute resting state brain scan before and after the three-day program. They also provided blood samples right before the intervention began and at a four-month follow-up. The brain scans showed that mindfulness meditation training increased the functional connectivity of the participants' resting default mode network in areas important to attention and executive control, namely the dorsolateral prefrontal cortex. Participants who received the relaxation training did not show these brain changes. The participants who completed the mindfulness meditation program also had reduced IL-6 levels, and the changes in brain functional connectivity coupling accounted for the lower inflammation levels. "We think that these brain changes provide a neurobiological marker for improved executive control and stress resilience, such that mindfulness meditation training improves your brain's ability to help you manage stress, and these changes improve a broad range of stress-related health outcomes, such as your inflammatory health," Creswell said.

In six studies with more than 4,600 participants, researchers found an almost even split between people who tended to value their time or money, and that choice was a fairly consistent trait both for daily interactions and major life events. "It appears that people have a stable preference for valuing their time over making more money, and prioritizing time is associated with greater happiness," said lead researcher Ashley Whillans, a doctoral student in social psychology at the University of British Columbia. The researchers found an almost even split with slightly more than half of the participants stating that they prioritized their time more than money. Older people also were more likely to say that they valued their time compared to younger people. "As people age, they often want to spend time in more meaningful ways than just making money," Whillans said. The researchers conducted separate surveys with a nationally representative sample of Americans, students at the University of British Columbia, and adult visitors of a science museum in Vancouver. Some of the studies used real-world examples, such as asking a participant whether he would prefer a more expensive apartment with a short commute or a less expensive apartment with a long commute. A participant also could choose between a graduate program that would lead to a job with long hours and a higher starting salary or a program that would result in a job with a lower salary but fewer hours. A participant's gender or income didn't affect whether they were more likely to value time or money, although the study didn't include participants living at the poverty level who may have to prioritize money to survive. If people want to focus more on their time and less on money in their lives, they could take some actions to help shift their perspective, such as working slightly fewer hours, paying someone to do disliked chores like cleaning the house, or volunteering with a charity. While some options might be available only for people with disposable income, even small changes could make a big difference, Whillans said. "Having more free time is likely more important for happiness than having more money," she said. "Even giving up a few hours of a paycheck to volunteer at a food bank may have more bang for your buck in making you feel happier."

It turns out that getting in the Christmas spirit can be good for your mental health

A study has found that performing small acts of kindness for others can give us a better outlook on things and help us to better deal with stress. "Stressful days usually lead us to have a worse mood and poorer mental health, but our findings suggest that if we do small things for others, such as holding a door open for someone, we won't feel as poorly on stressful days," researcher Emily Ansell said. The findings suggest "prosocial behavior" might someday be a useful course of treatment for people suffering from chronic stress or depression. Previous lab-based studies have shown similar results, but Ansell and her team wanted to see if they held true in the real world. Researchers had 77 adults use their cellphones to report stressful events, acts of kindness, and their emotional state every day for two weeks. The participants averaged one or two helpful acts per day. But those who logged more than that had improved well-being and were less affected by stress. "The holiday season can be a very stressful time, so think about giving directions, asking someone if they need help, or holding that elevator door over the next month," Ansell said. "It may end up helping you feel just a little bit better."

People who have a higher sense of purpose in life are at lower risk of death and cardiovascular disease

"Possessing a high sense of purpose in life is associated with a reduced risk for mortality and cardiovascular events," according to the study by Drs. Randy Cohen and Alan Rozanski and colleagues at Mt. Sinai St. Luke's-Roosevelt Hospital, New York. While the mechanisms behind the association remain unclear, the findings suggest that approaches to strengthening a sense of purpose might lead to improved health outcomes. Using a technique called meta-analysis, the researchers pooled data from previous studies evaluating the relationship between purpose in life and the risk of death or cardiovascular disease. The analysis included data on more than 136,000 participants from ten studies - mainly from the United States or Japan. The US studies evaluated a sense of purpose or meaning in life, or "usefulness to others." The Japanese studies assessed the concept of ikigai, translated as "a life worth living." The study participants, average age 67 years, were followed up for an average of seven years. During this time, more than 14,500 participants died from any cause while more than 4,000 suffered cardiovascular events (heart attack, stroke, etc). The analysis showed a lower risk of death for participants with a high sense of purpose in life. After adjusting for other factors, mortality was about one-fifth lower for participants reporting a strong sense of purpose, or ikigai. A high sense of purpose in life was also related to a lower risk of cardiovascular events. Both associations remained significant on analysis of various subgroups, including country, how purpose in life was measured, and whether the studies included participants with pre-existing cardiovascular disease. There is a well-documented link between "negative psychosocial risk factors" and adverse health outcomes, including heart attack, stroke, and overall mortality. "Conversely, more recent study provides evidence that positive psychosocial factors can promote healthy physiological functioning and greater longevity," according to the authors. The new analysis assembles high-quality data from studies assessing the relationship between purpose life and various measures of health and adverse clinical outcomes. The researchers write, "Together, these findings indicate a robust relationship between purpose in life and mortality and/or adverse cardiovascular outcomes." While further studies are needed to determine how purpose in life might promote health and deter disease, preliminary data suggest a few basic mechanisms. The association might be explained physiologically, such as by buffering of bodily responses to stress; or behaviorally, such as by a healthier lifestyle. "Of note, having a strong sense of life purpose has long been postulated to be an important dimension of life, providing people with a sense of vitality motivation and resilience," Dr. Rozanski comments. "Nevertheless, the medical implications of living with a high or low sense of life purpose have only recently caught the attention of investigators. The current findings are important because they may open up new potential interventions for helping people to promote their health and sense of well-being."

Training in meditation and other mindfulness-based techniques brings lasting improvements in mental health and quality of life for patients with inflammatory bowel diseases (IBD)

"Our study provides support for the feasibility, acceptability, and effectiveness of a tailored mindfulness-based group intervention for patients with IBD," concludes the research report by Dr. David Castle, a psychiatrist at St. Vincent's Hospital, Melbourne, Australia, and colleagues. More research is needed to demonstrate the clinical benefits of mindfulness techniques - including whether they can help to reduce IBD symptoms and relapses. The researchers evaluated a mindfulness-based stress reduction (MBSR) program tailored for patients with IBD. The study included 60 adults with IBD: Crohn's disease or ulcerative colitis. The patients' average age was 36 years, and average duration of IBD 11 years. Twenty-four patients had active disease at the time of the study. The MBSR intervention consisted of eight weekly group sessions plus a daylong intensive session, led by an experienced instructor. The program included guided meditations, exercises designed to enhance mindfulness in daily life, and group discussions of challenges and experiences. Participants were also encouraged to perform daily "mindfulness meditation" at home. Thirty-three patients agreed to participate in the MBSR intervention, 27 of whom completed the program. Ratings of mental health, quality of life, and mindfulness were compared to those of the 27 patients who chose not to participate (mainly because of travel time). The MBSR participants had greater reductions in anxiety and depression scores, as well as improvement in physical and psychological quality of life. They also had higher scores on a questionnaire measuring various aspects of mindfulness - for example, awareness of inner and outer experiences. Six months later, MBSR participants still had significant reduction in depression and improvement in quality of life, with a trend toward reduced anxiety. The patients were highly satisfied with the mindfulness intervention. Anxiety, depression, and decreased quality of life are common in patients with IBD. Psychological distress may lead to increased IBD symptoms and play a role in triggering disease flare-ups. Previous studies have shown benefits of MBSR for patients with a wide range of physical illnesses, but there is limited evidence on mindfulness-based interventions for patients with IBD. The new results show that the MBSR approach is feasible and well-accepted by patients with IBD. The study also suggests that training patients in mindfulness practices to follow in daily life can lead to significant and lasting benefits, including reduced psychological distress and improved quality of life. Dr. Castle comments, "This work reinforces the interaction between physical and mental aspects of functioning, and underscores the importance of addressing both aspects in all our patients."

A randomized trial of people with two common forms of arthritis has found that yoga can be safe and effective for people with arthritis

Johns Hopkins researchers report that 8 weeks of yoga classes improved the physical and mental well-being of people with two common forms of arthritis, knee osteoarthritis and rheumatoid arthritis. The study is believed to be the largest randomized trial so far to examine the effect of yoga on physical and psychological health and quality of life among people with arthritis. "There's a real surge of interest in yoga as a complementary therapy, with 1 in 10 people in the U.S. now practicing yoga to improve their health and fitness," says Susan J. Bartlett, Ph.D., an adjunct associate professor of medicine at Johns Hopkins and associate professor at McGill University "Yoga may be especially well suited to people with arthritis because it combines physical activity with potent stress management and relaxation techniques, and focuses on respecting limitations that can change from day to day." Arthritis, the leading cause of disability, affects 1 in 5 adults, most of whom are under 65 years of age. Without proper management, arthritis affects not only mobility, but also overall health and well-being, participation in valued activities, and quality of life. There is no cure for arthritis, but one important way to manage arthritis is to remain active. Yet up to 90% of people with arthritis are less active than public health guidelines suggest, perhaps due to arthritis symptoms such as pain and stiffness, but also because they are unsure of how best to remain active. The study recruited 75 people with either knee osteoarthritis or rheumatoid arthritis. Participants were randomly assigned to either a wait list or eight weeks of twice-weekly yoga classes, plus a weekly practice session at home. Participants' physical and mental well-being was assessed before and after the yoga session by researchers who did not know which group the participants had been assigned to. Compared with the control group, those doing yoga reported a 20% improvement in pain, energy levels, mood and physical function, including their ability to complete physical tasks at work and home. Walking speed also improved to a smaller extent, though there was little difference between the groups in tests of balance and upper body strength. Improvements in those who completed yoga was still apparent nine months later. Safety was a priority in the study, the authors say. "For people with other conditions, yoga has been shown to improve pain, pain-related disability and mood," says Bingham. "But there were no well-controlled trial of yoga that could tell us if it was safe and effective for people with arthritis, and many health professionals have concerns about how yoga might affect vulnerable joints given the emphasis on changing positions and on being flexible. Our first step was to ensure that yoga was reasonable and safe option for people with arthritis. Our instructors were experienced yoga therapists with additional training to modify poses to accommodate individual abilities." Participants were screened by their doctors prior to joining the study, and continued to take their regular arthritis medication during the study. The researchers have developed a checklist to make it easier for doctors to safely recommend yoga to their patients, Bingham says. People with arthritis who are considering yoga should "talk with their doctors about which specific joints are of concern, and about modifications to poses," suggests Bingham. "Find a teacher who asks the right questions about limitations and works closely with you as an individual. Start with gentle yoga classes. Practice acceptance of where you are and what your body can do on any given day."
