How we can strengthen neural and physiological responses through cross-lateral connectivity practises…

If you’ve ever tried patting your head while rubbing your belly, you’ll have experienced cross-lateral (CL) connectivity: simultaneous, asymmetrical movement. This requires left-right brain integration; both hemispheres of the brain working symbiotically. In the example of head-patting and belly-rubbing, the CL movement is a limb from one side doing something different to those on the other side, but it can also include any movement that crosses over the midline, such as right hand touching left knee. In terms of yoga, this could be seen as another level of ‘union’, where body, breath and mind are drawn to centre.

Cross-lateral practises keep our neural pathways firing off, equally mapping across both directions. Where the movement pattern is familiar, it may feel smooth and integrated, but if it’s new and unfamiliar, practice and focussed...

We know intuitively that when we move around, we feel clearer, sharper. When we don't move around enough, then we can feel more mentally sluggish, memory can become little harder to access, and reactions slower.

We can divide cognitive process into six types – attention, perception, memory, language, learning, and higher reasoning. These can both can occur simultaneously and independently, they rely upon each other and intertwine for that orchestration of how we think, feel and move our way through life. Learning new skills and new ways of thinking are supported when we also learn new movement patterns eg a new dance, type of movement to increase our cognitive fitness and longevity of our mental processes.

When we get moving, we increase circulation, we exercise the blood vessels themselves and this helps to prevent neurodegenerative conditions known to create cognitive impairment (Journal of Internal Medicine, 2011; 269(1): 107-117). Exercise also helps to control blood sugar...

With more and more people facing life-threatening illnesses stemming from sedentary culture, yoga and movement teachers have a critical role to play

“Sitting is the new smoking” was a sensational headline which rippled through the news last year, but was this over-dramatic? Increasing evidence shows that it is worth examining issues facing our ever-increasing sedentary culture.

Most people, especially movement teachers and bodyworkers who see these issues across a broad spectrum of clients, associate long-term sitting with structural issues and pain. But there is also growing discussion around the correlation between increased sitting and metabolic and chronic, inflammatory conditions; often referred to as ‘diseases of Western civilisation’. A study of 4,811 British public servants was published this year^[1], which followed people who were on average 44 years old, with no incidence of diabetes, heart or circulatory problems at the start. Over the next 13...

We explore how sedentary culture is causing us more serious harm than achy backs and necks and how we can consciously shift this…

Sitting has been described as “the new smoking”, one of the root causes of some of the diseases of modern Western civilisation. And the problems arising from us sitting so much are far more ominous than the postural issues you might think; including metabolic and chronic, inflammatory conditions. A study of British public servants^[1] examined how low long-term health risks for conditions such as type 2 diabetes, heart disease and an early death could stem from sedentary work.

What’s the harm in sitting?

We might wonder why sitting is so bad, as it seems natural to sit and focus or relax by sinking into the sofa? But consider that there is no comfy furniture in the wild; we were designed within nature and much of our function is bound up in those constant shifts where we would have squatted, sat on uncomfortable surfaces and kept...

Sugar is addictive

It’s a rare person who is immune to the call of the sweet stuff when tired, stressed, fed-up or hearing that “I deserve it” inner voice. We can dismiss indulgence in cakes, biscuits and sodas as ‘treats’ but the truth is that high-sugar foods like have been shown to affect the same opioid receptors in the brain that are activated by drugs like cocaine and morphine¹. With regular sugar consumption shown to create patterns of craving, bingeing and withdrawal, it has earned its growing recognition as an addictive substance as well as contributing to obesity, inflammation and chronic disease^2,3,4,5,6.

Cravings for instant hits

Craving is the uncontrollable want for something immediately; as sugar in the form of glucose is our main energy source, it represents the most immediate ‘quick-fix’ when we feel an imperative to get a task done or the need to protect ourselves. Our brains are our most important survival organ and...

The psoas muscle that allows us to stand proudly upright, is located deep within the front hip joint and lower spine. As a potential source of lower back and hip pain, to simply view its involvement in a mechanistic way is to only see a fraction of the bigger picture. As the only muscle that connects top and bottom body, its role in bipedal standing and walking is critical for alignment and movement, but also for our feelings of well-being. As we gauge its ease or non-ease from deep in the belly, tension in the psoas affects us on a deeply emotional level; it acts as a messenger to and from the brain and stores responses to replay them when we remember, imagine or revisit situations that cause us difficulty.

Adding some simple movements and sensitivity to your exercise programme can make the difference between creating more tension and finding a fluidity and refinement of movement that feels in concord with your natural body needs.

The Psoas Muscle

The psoas is a multi-joint...

Pelvic Asymmetry

If we look at an anatomical picture of the human skeleton, it would be easy to assume that being fully symmetrical has some kind of normality. Yet, it is actually extremely rare for us to stand equally weighted on both feet, unless instructed to do so in an exercise class. So many people may be unaware that they may have repercussions in the lower back, hips, knees and shoulders from pelvic asymmetry (PA).

The pelvis is the bony bowl-shaped structure at the bottom of the spine; where our legs attach and the cradle for the lower spine bone (the sacrum) to sit into. It can be tilted away from its healthiest positioning in many ways, including forward (anterior), back (posterior), or with rotation, but here we are focussing on lateral or side asymmetry. This is also known as Pelvic Obliquity, where it is tilted to one side, with the spine curved to the opposite. One side of the pelvis is higher than the other, so when standing the top of one iliac crest (felt as the...

Easing spinal compression/spinal stenosis

With the inevitability pushing down of gravity we can expect some spinal compression as part of the natural ageing process, but what happens when this tips over into pathology and pain? With more and more people suffering back pain, some understanding of where the design of our spine meets how we move – and modern postural patterns – may help us find space and relief at our central axis. 

The human spine is curved (see fig.1) in an s-shape and this is an important design for our bipedal (two-legged) upright sitting or standing stance; it allows the weight distribution to shift as we move and hold our head and organs vertically up from the ground.

Our spines consist of 24 individual sections of bone (vertebrae) with rubbery discs in between to keep them separate and the whole spinal column freely mobile. This also creates space for the spinal canal, a cavity running through each of the vertebrae, which encloses the spinal...

Research shows that around 75-85 percent of the American population experience back pain in their lives (Neurol Clin.,2007;25(2):353-7). Contrary to much investigation into inflammation (such as arthritis) and more serious conditions, most of the root cause is understood to be structural and mechanical in nature – affected by the way we move, live and use our bodies day-to-day.

Those with sedentary jobs have higher incidence and less when they move around regularly (Indian J Occup Environ Med. 2016;20(3):125-128). Much sitting on chairs can shut down the natural outward range of motion (ROM) in the hips and alter the natural ‘C-curve’ of the lower back, creating a compression into the discs of the lumbar spine (the lower back) whether we tend to sink into a forward or backwards placed pelvis. Chair sitting and sofa slumping has replaced sitting on the floor, often cross-legged or with legs bent to one side on the ground in ways that our musculo-skeletal system...

With experts estimating that 80% of people will experience lower back pain at some time in their lives (Neurol Clin. 2007;25(2):353-71), this is an issue that is only getting worse as we spend more time sitting on chairs. It is no surprise that moving is an effective antidote for this debilitating issue (Spine. 2008;8(1)213-225), but the pain involved can create a Catch-22 cycle. The holding and fear of exacerbating the issue can leave people avoiding exercise, becoming confused about their capabilities, and what can help, and what can worsen their symptoms.

The sacroiliac (SI) joint

Understanding some lower back anatomy can help us make sense of why this area may become a source of tightness, pain or inflammation. Many issues arise at the SI joints, the two sites where the lowest bone in the spine – the sacrum – sits into the bowl-like bone of the pelvis (fig.1). These joints are calibrated to the very individually human bipedal way of standing, so the sacrum acts like...

The Benefits of Walking on Uneven Ground

As humans, we have evolved to have certain patterns of physical activity that are necessary for health.¹ In fact, we’re built for long-distance walking, and it’s estimated that our hunter/gatherer ancestors covered daily distances in the range of 6–16 km (3.5–10 miles). While walking may be our most natural form of exercise, humans learned this unusual mode of transport on rough surfaces—far from the predictability of pavements and man-made flooring.

All of our ancestors’ walking and running was done on natural surfaces like grass and rocks, and often over uneven ground. Our upright two-legged (bipedal) walking style evolved alongside a nomadic lifestyle that was not just for walking to new camps, but also for getting to and from sources of food, water and wood.² It’s even theorised that part of our large brain growth was to address the various challenges of bipedal upright walking on naturally uneven...

Anxiety is a common feature in life for many. The agitated, fearful and overwhelming sensations that it brings can ripple through our lives with devastating effect. For those who tend towards anxiety, overstimulation from situations or inner turmoil can trigger feelings of agitation and needing to withdraw. For those that need lots of space in life to find calm and regroup, a yoga practice can provide both a refuge and the nervous system soothing that can allow them to cope with the demands of life.

In our fast-paced and information heavy world, anxiety is on the increase as the ‘constant alert’ this continual input provokes becomes part of the landscape. Whether anxiety is trait – part of what are now commonly termed anxiety disorders, or part of a period of chronic or extreme stress or trauma, the feelings of dread, panic, loss of control, palpitations, hyperventilation, wanting to escape and unable to...
