My relationship with water has been a complicated one. Although my earliest memories are of joyful play in the water, fear experiences would subsequently present themselves in my life. The most memorable fear experience being a near-death drowning in the Old Man River of the Kananaskis, southwestern Alberta, when I was seventeen. Had my brother failed to pull me from those river rapids that moment would have been the end of my relationship with water. Luckily, the experience just left me with a debilitating fear of running/moving water that resulted in a degree of avoidance throughout much of my adult life.
Despite this trauma, I went on to pursue my vision of clinical practice as a neuropsychologist serving patients with dementia and traumatic brain injuries. I have felt honoured to share the journey for those facing end of life or with traumatic change to their brains. However, after twenty-five years of secondary exposure to the trauma of others, the weight of their suffering was taking its toll on my own health. This was compounded, around age fifty, with several personal stressors (i.e., a seriously ill child and sudden retirement of my husband), which served to demand more self-care be incorporated in my life.
Strangely, these crises brought me back to the moving water I feared so much from my past as I impulsively signed up for a women’s yoga and surf retreat with Swell Women in Maui. This experience, which I had initiated to escape my life stress, actually served as exposure therapy (exposure to the source of anxiety/fear in a controlled context in order to help overcome the distress) for my fear of moving water. I emerged from the week with a greater sense of balance and bravery to face the stress I was returning to at home. Since then I have surfed various locations throughout North and Central America with many remarkable women from around the world who also are challenging their own limits in their own way.
My background in neuroscience subsequently brought me to explore our understanding of ocean exposure effects on our brains. For instance, studies suggest ocean sounds activate our prefrontal cortex (the most evolved and complex part of the brain and includes the center for regulation of our stress response). Ocean waves sounds have also been found to play a role in balancing serotonin levels and in reducing cortisol, both involved in regulating mood and stress response. This seems demonstrated in therapeutic surfing programs, such as those geared towards veterans with Post Traumatic Stress Disorder. In my own experience, this ocean environment not only provided much needed exposure therapy for my fear of moving water but also engaged my prefrontal cortex to enhance regulation of my high levels of stress. With this framework, I can imagine the process of surfing provides opportunity for my prefrontal cortex to regulate both the “fight-flight” response with the surge of catching a wave or being tumbled by one, as well as the “rest and store” response, triggered by sitting on the board feeling and listening to the rhythm of waves between rides.
However, this is not the only potential benefit. There is growing attention to the concept of neuroplasticity, our brain’s ability to change, such as creating new neural pathways. What we now know of neuroplasticity in aging is that novel experiences may help set new neural pathways, which likely strengthen and perhaps provide a protective effect for neural tissue. This is why new experiences throughout our lifespan may be a means of ‘beefing up’ our brain tissue. This concept brought me to become certified as an open water diver this year at age fifty-five. Once again, fear presented itself during the certification process with thoughts about I’m too old to learn something new and fear of being forty feet under water with only a regulator to keep me alive. However, as my sixteen-year-old son wanted to pursue this goal, I persisted to complete the requirements in order to share the experience with him. This not only strengthened my relationship with my son, but also with the ocean and the amazing creatures within it.
Recently, I had opportunity to attend a workshop of Mind Body Medicine in Ucluelet, BC which inspired my hope to integrate understanding of neuroscience with the healing powers of the ocean and other lifestyle factors for brain health and healthy aging. In reflection on this, I find it is interesting to consider that the three animals with the greatest potential life longevity are sea creatures, such as the Greenland shark, bowhead whale and Galapagos giant tortoise). As we seek greater understanding for healing of our body, brain and mental health, it seems we should turn our minds to the ocean. Certainly, in my own life, the ocean has been a revelation for its power to help me to manage stress, both personally and at work. For this, I am grateful.
