Aging Healthily – Yoga and Cellular Aging

psyjdc 4 Comments

Aging is inevitable. We can’t stop it or reverse the aging process. But, it is becoming more apparent that life-style changes can slow down the process and allow us to live longer and healthier lives.

The genes govern cellular processes in our bodies. One of the most fundamental of these processes is cell replication. Our bodies are constantly turning over cells. Dying cells or damaged are replaced by new cells. The cells turn over at different rates but most cells in the body are lost and replaced between every few days to every few months. Needless to say were constantly renewing ourselves.

As we age the tail of the DNA molecule called the telomere shortens. When it gets very short cells have a more and more difficult time reproducing and become more likely to produce defective cells. On a cellular basis this is what produces aging. There is an enzyme in the body called telomerase that helps to prevent shortening of the telomere. So, processes that increase telomerase activity tend to slow the aging process.

Previous research has shown that an intensive meditation practice can increase telomerase activity and slow telomere shortening. These results suggested that meditation could slow aging and increase life span. It’s been anecdotally reported for years that people who practice yoga  tend to live long lives. There has, however, not been any systematic empirical evidence obtained to confirm or deny these anecdotes.

In today’s Research News article “Telomerase activity and cellular aging might be positively modified by a yoga-based lifestyle intervention.”

Kumar and colleagues produce evidence from a single case study that yoga practice increases telomerase activity. In addition they show that markers of oxidative stress, another indicator of aging, are reduced with yoga practice.

These are very exciting findings that must be interpreted cautiously since they are from a single case. But, should they be seen in controlled future investigation could suggest that yoga practice, like meditation, can slow cellular aging and perhaps increase longevity. It should be emphasized that the yoga practice used by Kumar and colleagues included meditation. It remains to future research to identify if the observed effects are due to the postures, or to breath control in yoga or to the meditation component or all three.

So, practice yoga and age slowly and healthily.

Age Healthily – Protect the Brain with Yoga

psyjdc 4 Comments

The aging process involves a progressive deterioration of the body including the brain. It actually begins in the late 20s and continues throughout the lifespan. It cannot be stopped or reversed. But, the deterioration can be slowed and to some extent counteracted. This is true for both physical and mental deterioration including degeneration and shrinkage of the nervous system.

Aging healthily to a large extent involves strategies to slow down the deterioration. Meditation has been shown to slow down the deterioration of the nervous system with aging. It acts by increasing the amount of grey matter in the brain through a process referred to as neuroplasticity. Brain areas that are heavily used tend to grow larger while those that are underutilized tend to grow smaller.

In a previous post we described how yoga slowed or reversed age related decline in muscle strength and flexibility (See below). In today’s Research News article “Neuroprotective effects of yoga practice: age-, experience-, and frequency-dependent plasticity”

https://www.facebook.com/ContemplativeStudiesCenter/photos/a.628903887133541.1073741828.627681673922429/1050712994952626/?type=1&theater

http://www.ncbi.nlm.nih.gov/pmc/articles/PMC4428135/

Villemure and colleagues demonstrate for the first time that yoga practice also protects the nervous system from deterioration. They showed that with age there was a decline on brain grey matter volume in healthy physically active people, but there was no decline in experienced yoga practitioners.

Interestingly, the more yoga practice the better the protection, the higher the grey matter volume. Yoga consists of postures, breath practice and meditation. It appears that the combination of postures and meditation are the most significant aspects of yoga practice for neuroprotection. It was already known that meditation helped to protect against age related brain deterioration. These results suggest that yoga adds another neuroprotective element in practicing postures.

Yoga practitioners had larger sensory cortex areas than non-practitioners. This is probably because of yoga’s emphasis on paying attention to sensations and visualization techniques used during practice. Also, the largest effects of yoga were seen in the left hemisphere. There is strong evidence that the left hemisphere is responsible for positive emotions. This then suggests that yoga promotes happiness by increasing the size of the left hemisphere. In addition, enlargement was seen in areas responsible for stress management. This provides a potential mechanism for yoga’s ability to relieve stress.

These are exciting findings. The results could provide credence for the long rumored ability of yoga to increase lifespan. They also suggest that the meditative aspects of yoga are very important and that using yoga simply for exercise may be ignoring  very important aspect of yoga for the protection of the brain.

So, practice yoga and age healthily.

The aging process involves a progressive deterioration of the body. This cannot be stopped or reversed. But, the deterioration can be slowed and to some extent counteracted. This is true for both physical and mental deterioration. But, today’s article, “Age related differences of selected Hatha yoga practices on anthropometric characteristics, muscular strength and flexibility of healthy individuals.”

http://www.ncbi.nlm.nih.gov/pmc/articles/PMC4278134/?report=printable

https://www.facebook.com/ContemplativeStudiesCenter/photos/a.628903887133541.1073741828.627681673922429/1015482441809015/?type=1&theater

is focused on the physical deterioration in aging.

As we age we increase body fat and loose muscles mass and strength. The bones become less dense and weaker and thereby more prone to breaking. Cartilage that lines the joints tend to thin leading to arthritis and the ligaments that hold the muscles and joints together tend to harden making us less flexible and prone to injury. Inactivity in aging can exacerbate all of these musculoskeletal changes.

Yoga practice appears to help to slow or reverse these changes. Today’s article demonstrates that the increase in fat mass with aging and the consequent increase in body weight are slowed by daily Hatha yoga practice. The decreased muscle strength as well as the decreased flexibility is also slowed in yoga practitioners. Hence, yoga is an excellent practice for maintaining the individual’s strength, flexibility, and body composition all of which are important for healthy aging.

In addition to the direct benefits there are also a plethora of indirect benefits. The individual looks and feels better. This can lead to improved self-image and even higher levels of activity. These in turn can lead to more frequent and better social interactions. This in addition to the social interactions inherent in group yoga practice. The loss of these social interactions are a major contributor to loneliness and depression in aging. Hence, indirectly, yoga practice can lead to improved social and psychological health.

So, age healthily by practicing yoga!

Yoga for Trauma in Children

psyjdc 4 Comments

“Yoga’s ability to touch us on every level of our being—physical, mental, emotional, and spiritual—makes it a powerful and effective means for trauma victims to reinhabit their bodies safely, calm their minds, experience emotions directly, and begin to feel a sense of strength and control.” – van der Kolk

Trauma comes in many forms, from abuse to warfare, from children to the elderly, from natural and man-made causes, and from the rich to the poor. But, regardless of the cause or the characteristics of the individuals, it leaves in its wake a syndrome of posttraumatic symptoms which can haunt the victims for the rest of their lives. These include persistent recurrent re-experiencing of the traumatic event, including flashbacks and nightmares, loss of interest in life, detachment from other people, increased anxiety and emotional arousal, including outbursts of anger, difficulty concentration, and jumpiness, startling easily.

There have been many treatments employed each with varying but limited success. Mostly these treatments have been used with adults. But, children who are victims of trauma have been the focus of very few studies of therapeutic interventions. The lack of focus is surprising as it’s been estimated that of adolescents, 8% had been exposed to sexual assault, 17% physical assault, and 39% had witnessed violence. It is estimated that 15% of children show symptoms of Posttraumatic Stress Disorder (PTSD)

Mindfulness training and yoga practice have been found to be effective for trauma in adults, particularly from the middle and upper classes. It has yet to be shown if they can be employed effectively with children and with individuals from low socioeconomic categories. In today’s Research News article “Yoga to Reduce Trauma-Related Distress and Emotional and Behavioral Difficulties Among Children Living in Orphanages in Haiti: A Pilot Study”

https://www.facebook.com/ContemplativeStudiesCenter/photos/a.628903887133541.1073741828.627681673922429/1049082531782339/?type=1&theater

Culver and colleagues begin to address this issue by employing yoga training to treat traumatized orphans in Haiti. They found that yoga reduced the symptoms of trauma in these children and showed a trend toward a reduction in behavioral difficulties.

These findings are very encouraging. Trauma affects both the mind and the body. Yoga works with both, but is particularly targeted to the body. The relaxation produced by yoga practice is a soothing antidote to the hyperaroused state that is so characteristic of trauma victims. Yoga appears to reduce activity in the sympathetic nervous system, the fight or flight system. Hence, yoga appears to produce both muscular and physiological relaxation, directly addressing a symptom of trauma.

The practice of focusing attention that is so central to yoga training addresses the difficulties with concentration that are characteristic of trauma victims. The focus of attention in yoga is on the sensations from the body. This can directly address the numbing of sensation that is frequently reported by trauma victim. In addition, getting in touch with bodily sensations helps trauma victims get more in touch with their emotions allowing them to better work with them.

So, yoga appears to be an excellent treatment for trauma alone but preferably in combination with other treatment modalities.

Heart Healthy Yoga

Metabolic Syndrome is a major risk factor for cardiovascular disease and diabetes. It generally results from overweight and abdominal obesity and includes high blood pressure, insulin resistance and elevation of plasma cholesterol and triglycerides. It is an important risk factor as it increases the risk of developing type-2 diabetes five-fold and heart attack or stroke three-fold.

Metabolic Syndrome incidence has been rising rapidly approaching epidemic proportions. It is estimated that it currently affects 34% of US adults. Needless to say this is a major health problem. The good news is that timely treatment can prevent or reverse the risk. The simplest treatment is simply exercise and weight loss.

Yoga has been used to promote health and well-being for thousands of years. In today’s Research News article “Effects of 1-year yoga on cardiovascular risk factors in middle-aged and older adults with metabolic syndrome: a randomized trial”

https://www.facebook.com/ContemplativeStudiesCenter/photos/a.628903887133541.1073741828.627681673922429/1045854842105108/?type=1&theater

http://www.ncbi.nlm.nih.gov/pmc/articles/PMC4440276/

Siu and colleagues examine whether yoga is an effective treatment for metabolic syndrome. They found that a 1-year yoga program reduced waist circumference, blood pressure, and resting heart rate and increased activity levels. This suggests that yoga is effective in reducing the symptoms of the Metabolic Syndrome.

Probably the most important finding was a 3.5% reduction in waist circumference. Most of the Symptoms of the Metabolic Syndrome result from a high level of abdominal fat. This produces the insulin resistance which in turn increases diabetes risk and raises cholesterol and triglycerides which increases cardiovascular risk. Hence, a key to treatment is to reduce this belly fat and yoga appears to be effective at doing just that.

Yoga is in part an exercise and this by itself could be responsible for the improvement. Indeed yoga practice increased activity levels which promotes the conversion of fat to muscle. So, even if there is no change in weight there is a reduction in abdominal fat, the primary culprit in Metabolic Syndrome.

Yoga, however, produces other beneficial effects that could be responsible for the improvement in Metabolic Syndrome. Yoga practice reduces the physiological symptoms of stress. It reduces the levels of stress hormones and it relaxes the sympathetic nervous system, the fight or flight system. Stress exacerbates the symptoms of Metabolic Syndrome. By reducing the physiological mechanisms by which stress affects Metabolic Syndrome, yoga can markedly improve the symptoms. In addition, by reducing stress, yoga can improve immune system response, increasing the individual’s ability to fight off diseases.

So practice yoga and reduce your risk of cardiovascular disease or diabetes.

Effectiveness of Meditation, Yoga and Prayer

psyjdc Leave a comment

People engage in contemplative practices for a variety of reasons, including increased mindfulness or spiritual development. But, regardless of the goal, it is not known what contemplative practice works the best to achieve the goal. In addition, it is not known what pattern of practice works the best with each type of practice.

These questions are investigated in today’s Research News article “Meditation has stronger relationships with mindfulness, kundalini, and mystical experiences than yoga or prayer.”

https://www.facebook.com/ContemplativeStudiesCenter/photos/a.628903887133541.1073741828.627681673922429/1022155664475026/?type=1&theater

https://www.researchgate.net/publication/277020080_Meditation_has_stronger_relationships_with_mindfulness_kundalini_and_mystical_experiences_than_yoga_or_prayer

Regardless of whether meditation, yoga, or prayer is practiced, higher levels of mindfulness occur. But, the highest levels of mindfulness are produced by meditation. This was also true for kundalini and mystical experiences.

Kundalini experiences are changes in the physical energetics of the body, including extreme levels of energy, physical symptoms, involuntary movements etc. Kundalini effects will be the subject of an upcoming CMCS essay (stay tuned). These experiences were first documented in the ancient yogic traditions. So, it is surprising that meditation has a larger impact than yoga practice.

Mystical experiences have always been associated with meditation but also strongly with prayer. The effectiveness of prayer in producing mystical experiences is well exemplified by the Christian or Sufi mystics. So, it is surprising that prayer is not particularly effective.

One explanation for the relative ineffectiveness of yoga and prayer is the reasons and the way they are practiced in modern cultures. Yoga is often treated as a fitness practice rather than a contemplative practice and prayer is often used mechanically or for petition to a deity rather than for contemplation. So, it should not be surprising that overall these practices are not as potent in producing mindfulness, kundalini, and mystical experiences as meditation.

It was clear, however, that no matter what practice is used the amount of practice is the most important factor in its effectiveness. It’s the amount of time spent each week practicing and it’s the number of years of practice that best predict heightened states. How frequently one practices, how long each session lasts, or whether practice occurs in groups or alone doesn’t seem to matter. It’s simply the total amount of practice that is associated with effectiveness.

So, engage in contemplative practices, but do so in a contemplative manner, do so regularly, and invest time and patience in the practice and you will begin to reap the rewards.

Healthy Balance through Yoga

The body’s immune system fights off potentially damaging agents by producing an inflammatory response. This response attacks and destroys the culprits and thus maintains the integrity of the body.

This inflammatory response, however, must be restrained the rest of the time. Too much inflammation, particularly on a chronic basis can be as harmful as a lack of inflammation to infection. Balance between pro- and anti-inflammatory mechanisms is required for health.

When the system is out of balance such that the inflammatory response is dominant on a continuous (chronic) basis it tends to promote the development of cancer, diabetes, depression, heart disease, stroke, and Alzheimer’s disease. On the other hand, when the anti-inflammatory response is dominant on a continuous basis it leaves the individual vulnerable to infection. Hence, promoting the balance in the immune system is crucial for long-term health.

Yoga appears to do just that. Today’s Research News article, “Effect of Yoga Module on Pro-Inflammatory and Anti-Inflammatory Cytokines in Industrial Workers of Lonavla: A Randomized Controlled Trial” http://www.ncbi.nlm.nih.gov/pmc/articles/PMC4378732/

provides empirical evidence that yoga promotes immune balance.

This might be one explanation why yoga practitioners tend to be healthier and live longer.
