PTSD & Open Water Swimming: Atlantic Annie Finds Calm Within the Waves My Body Odyssey

- Medicine
The benefits of open water swimming are widely felt and observed but not yet fully documented by the scientific community, as they combine the effects of immersion in nature, cold water and strenuous exercise all at one time.
“It actually does change your pulse and it changes our physiology as humans,” says our protagonist, Atlantic Annie. “And it's apparently activating the parasympathetic nervous system, which I have come to understand over the last 10 years, is our relaxation response, activated when we sleep, when we're with our favorite pet, with a lover. And I was getting that by swimming.”
For Annie these benefits are particularly important because of childhood trauma which surfaced as full-blown PTSD some years later as an adult. She has since been successfully treating this chronic anxiety for two decades now, adding in open water swimming over the past ten years.
“I love the way I feel after, and I love the experience itself," Annie tells us after a swim at her favorite spot along the Southern New England shore. “And I haven't found many sports where I feel such a sense of calm.”
Annie is far from alone in feeling these benefits, according to our expert this episode, Dr. Heather Massey, a lecturer in Physiology at the University of Portsmouth (UK) and an avid open water swimmer.
“People have sent me their Garmin watch information about their resting heart rates,” Dr. Massey says, “and told me when their periods of regular outdoor swimming have been compared to when they haven't swam outdoors.”
Dr. Massey theorizes this calming effect has to do with a well documented phenomenon known as the Mammalian Diving Reflex. “Cold water swimming is what we call a perturbation, and it totally disrupts the status quo within the body,” she explains. “It's putting the body in a position where it needs to react to the stimulus of cold water.”
Open water swimming has serious risks and should not be undertaken alone or without prior medical consultation. But swimming safely against a small amount of potential risk may paradoxically have a calming effect on open water swimmers like Atlantic Annie and others with anxiety issues.
