Ashtanga yoga practice and sustainability || healthy and unhealthy stress


I picked up a copy of This Explains Everything from edge.org aggregating essays by 150 influential thinkers responding to the question – what is your favourite deep, elegant or beautiful explanation? Nassim Taleb essay on 'Hormesis is Redundancy' really resonated with me. Reflecting upon this also helped me to articulate some of the questions I have around the long-term sustainability of an Ashtanga yoga practice.

Hormesis occurs when an organism is exposed to a small dose of a harmful substance or stressor, resulting in the organism growing stronger or healthier. So enabling the organism to cope with a larger dose of the harmful substance or stressor in the future. So simplifying, I like to think of hormesis as healthy levels of stress stimulating growth. In a yoga context I can think of hormesis as experiencing stress (physical, mental or emotional) within a posture. As a result I grow in some sense stronger, more flexible and better able to cope with the stress of the posture. So the next time I take the posture I am, all other factors being equal (energy levels, time of day etc.), able to experience the posture in greater depth or more comfortably. I have heard several teachers explaining the underpinning rationale for ashtanga yoga practice in similar terms. So if I understood correctly at a Kino MacGregor workshop, she proposes that by experiencing and over time learning to cope with stressful poses in the asthanga sequence the practitioner benefits from learning to control the stress response of the autonomic (involuntary) nervous system.

So, this brought me to a question - what is the balance of benefits and risks in invoking the hormesis response on daily basis over many years in a traditional ashtanga yoga practice? Or alternatively phrased - where is the stress created by the ashtanga practice healthy and where is it not?
My approach to unpicking this question is of course shaped by my personal experiences of the practice. I have practiced ashtanga for about 4 years, for the last 2 year I have practiced daily. Whilst practicing daily I have experienced some fairly remarkable benefits (e.g. improvements in strength and flexibility of both my mind and body), but I have also experienced various injuries. For the past year or so I have had a nagging and recurring doubt that in medium-long term the ashtanga practice is unsustainable for me. Particularly, due to the likelihood of repetitive strain injuries from the daily repetition of the same postures over the years.

In returning to unpick the question I posed above, several thoughts immediately occur to me.
  • Some would argue (e.g. Peter Blackaby and William Broad) that there are fundamental issues with some yoga poses. In terms of the stresses they place on the body when aligned in inherently risky or unhealthy postures. This argument does resonant with my experience to some degree, and I perceive a degree of dogma around the nature of the postures and sequence - which do not seem to evolve to reduce the risk of injury. All that said it seems idealistic to expect yoga (particularly of the more gymnastic variety, such as ashtanga) to be free of the risk of injury. When I play tennis I accept the risk of injury and do my best to manage this through appropriate conditioning and rest.
  • The perspectives I have come across on injuries and the practice tend to be polarised. From the perspective that the practice is neutral and all injuries result from errors or an inappropriate approach on the part of the practitioner. To the perspective, that injuries are an inevitable part of the practice and the practitioner should accept this as a price worth paying for realising a multitude of benefits. Where does the middle ground lie between these perspectives? Is understanding this middle ground important in establishing a sustainable practice?
  • If I have finite resources to deal with stresses each day, does it make sense to expend a significant proportion these resources each day within my yoga practice. Typically practicing first thing in the morning before starting all my normal day to day activities.

I'm not sure I have reached much of a conclusion on the question of where the stress created by the ashtanga practice is healthy and where is it not? Other than it is very much a personal balance to be struck by the individual practitioner. Your thoughts and comments of course welcome!
