Meditate your way to a younger smarter brain
Several features in the media this week have giving some clear indications about the science behind keeping our brains in the best possible shape. Some of the advice falls into the generic wellbeing wisdom which now seems to be be associated with most health messages;
- eat more fresh fruit and vegetables, consume less processed meat
- take regular exercise
- give up smoking
- stay socially engaged
- keep active
- avoid stress, relax and sleep the right amount
- keep the brain working with appropriate activity and brain training
The last item on this wish list is unsettlingly vague given that it probably has the most significant impact on brain health. For example how can we define brain training (as almost everything we do can train the brain)? What is an appropriate level of activity and which parts of the brain should we focus on?
“In one study the brains of regular meditators were found to be years younger than non meditators”
In today’s Guardian, attention was drawn to a key finding of the MacArthur Studies of Successful Aging; that typically lifestyle and environment are more influential in our quality and length of life than genetic factors. This is also the general direction that brain science seems to be moving in with regards neurodegeneration. That although there are many questions left to be answered, limiting cognitive decline and reducing the risk of dementia may rest largely in our own hands.
Returning to the question of brain training, the big issue is to establish what kinds of intervention bring the greatest overall benefit? It is becoming increasingly apparent that narrow single task training such as Sudoku or word searches have a limited effect. Whereas maintaining high levels of brain activity and cognitive challenge are likely to keep a much broader area of the cortex young and healthy. The same principle needs to be applied if meditation systems are being used to maintain cognitive function. That the meditation or mindfulness method should be broad based and able to tap into both the intrinsic (internal) and extrinsic (task or external) networks. Activity in and between different neural networks is a key element in brain health and one frequently overlooked and poorly understood. To illustrate consider tonglen meditation, it combines compassion, nondual awareness and mindfulness, it allows the meditator to work with our internal visualisation and empathy systems. In addition it engages the important connectivity between introspection and external awareness.
Given what we know already about neurodegeneration, it seems likely that long term protection against cognitive impairment can be found in meditation methods built on nondual compassionate approaches.
