Hypermobility & Hypotension – Yoga Asana, Anxiety and Pain

Hypermobility, hyperextension, hyperflexability – these are different words all describing the same thing – a weakness or laxness in the connective tissue (fascia) of the joints. There is a tight link between anxiety and generalized hyper joint mobility as well as preliminary connections with depression, fibromaglia, chronic fatigue, and attention deficit (and hyperactivity) disorder. There is also evidence that this laxness in the the fascia is also related to issues of low blood pressure and a resulting problems such as POTS. It basically works like this: A lack of strenth in the connective tissue (fascia) surrouding the joint makes the joint and the tissue more susceptible to injury, injury signals the release of cytokines and creates inflammation and increased levels of cortisol in the blood. High levels of cortisol and generalizad inflammation is highly associated with all of the previously mentioned disorders as well as just more physical pain. Besides increasing the chance the injury and inflammation, the lack of blood flow through the system (due to a lack of engaging muscle fiber and connective tissue) results in low blood pressure – or hypotension. Hypotension can result in dizzyness, blurred vision, tiredness and difficulty getting blood from the digestive tract up to the heart. This in turn will also affect the digestion, the immune system and increase the liklihood of other chronic ailments, such as long covid. Things then only get worse for my fellow flexis since we are often drawn to activities where we can enjoy and showcase our great limberness and without proper joint stability, those hanumanasana splits without engaging the feet and leg muscles only makes things worse and increase our chances of inflammation and injury. Some people think that super flexis got it easy on the Yoga mat. WRONG. Those of us who are naturally flexible, or teachers who are guiding the practice of naturally flexible individuals, absolutely must pay even more attention to hand spine connection and foot pelvic alignment. Without engaging these connections which start in the karmendriyas (organs of action) of the hands and feet, the muscles around the bones and joints will not engage. Any lack of awareness to these foundational connections and active engagement, will increase the probability of hyperextension of the joint, injury and inflammation and all the benefits of Yoga Asana can easily transform from a discipline of holistic healing into one of chronic injury and poor system functioning. So if you are a naturally flexible human being, be careful with your practice and make sure that you are working with a teacher who can help you to protect your joints and engage those deep muscle fibers around the bones as well as guide you into a progressive practice of inversions and back bends to get the blood moving from the feet up into the heart and brain.

Yoga Asana and Vagus Nerve Function

Why physical posture affects your mood, perception of reality, creative and executive functioning. Research is identifying that a large part of our perceived reality has it’s basis in the ascending visceral communication of the body upwards to the brain (mainly through the vagus nerve), where it is then interpreted and then sent back to the body. Essentially acting like a feedback loop between gut, heart and brain. Why is this useful to know? Various studies have shown that simply changing our physical form has significant impact on our perceptions and experiences of the world. There is evidence that ‘good posture’ does equate to higher levels of wellbeing – even when walking. A ‘good posture” allows for better breath, which affects vagal tone. and relaxes the sympathetic autonomic nervous system (ie. the fight/flight stress response). Greater relaxation of the sympathetic system allows for greater resources to be used for executive and creative functioning rather than just survival. I mean how is your mind going to think about the next big project at school or work when it is recieving communication from the your body that it is in immediate danger? If your brain is recieving the message from your body that there is danger in the environment, it is only logical that survival comes first and resources (attention, blood, oxygen) will be allocated to figuring out to get back into safety and homeostasis. Contemplating creative and executive tasks will be put as second priority. In addition to reducing executive functioning, a slumped posture significantly increases attention and memory recall of negative stimuli – a key symptom of those suffering depression and anxiety. It is speculated that the hyper-attention to negative stimuli then results in a negative feedback loop between gut, heart and brain. Resulting not only in a more pessamistic outlook on life but also digestive problems such IBS. Therefore, according to the research, improving ones posture is one way to short-circuit this negative feedback loop. So all that talk about good posture (which starts in your FEET!!) isn’t just about reducing back pain! Lifting the heart up, pulling the shoulders down and back and relaxing the lower abdomen not only improves breath but also emotional and executive functioning.

The Enteric Nervous System and Vagus Nerve Function

The ENS (enteric nervous system) is composed of the largest accumlation of nerves in the human body. Yes. Even more than your brain!!! What and where is the ENS? The ENS is one of the three branches of the autonomic nervous system. It consists of a nerve plexus embeded in the intestinal wall that extends across the entire gastrointenstinal tract from the esophogus to the anus. Due to it’s massive network of neurons that are similar in structure, function, and chemical coding to it’s upstairs companion (the brain) – it has often been termed ‘the second brain’. But perhaps calling it the ‘second’ brain is not entirely correct, and perhaps even insulting to the ENS, as it has been demostrated in controlled animal studies that changing the information in the ENS directly influences the Hypothalamus – Pituitary – Adrenal axis (further upstairs) and has a significant effect on anxiety and stress behavior. Similar findings have been found in humans – albeit through more observational means. 80-90% of this this bottom up communication occurrs via that wandering wonder, the Vagus Nerve – not the other way around. So it kind of makes you wonder…who is controlling who? Which part of us is the ‘first brain’ and which is the ’second’? How much of our reality is composed of top down executive thought processes and how much of those thought processes are actually controlled by bottom up information sent by the ENS via the Vagus Nerve? Makes me contemplate my younger years when I found myself obsessed with Egyptian history and feeling a bit confused that such an advanced civilization would essentially throw out the brain but preserve the heart and other internal organs for all eternity. It also makes me deeply appreciate the wisdom of Yoga Asana. Yoga Asana is the only physical practice that I know of that specifically addresses the nervous system via the digestive tract and vagus nerve.  The very purpose of Yoga Asana isn’t just to make you more flexible or twist yourself into various forms to impress family and friends. The aim and purpose of Yoga is first and foremost to create SPACE. Space around the joints, space in the digestive tract which results in space around the enteric nervous system which then results in an increase in Vagus nerve tone leading to greater space between the breaths and finally space between thoughts. And that space between thoughts is where the ability to perceive the reality beyond the illusion of Maya (psychological conditioning) begins. Maybe these Yogi’s and Egyptian priests knew something that we are only now begining to uncover… Sources: Vagus Nerve as Modulator of the Brain-out Asis in Psychiatric and Inflammatory Disorders (2018) Effects of intestinal microbiota on Anxiety-like behavior (2011) The human enteric nervous system (2004) Control of gastrointestinal motility by the ‘gut brain’ the enteric nervous system (2005) The enteric nervous system and gastrointestinal innervation: integrated local and central control (2014) #vagusnerve #secondbrain #embodiment #karmukayoga #nervoussystem
