A new study conducted by Swansea University is exploring the potential of cold-water immersion (CWI) therapy to alleviate symptoms of Post-Traumatic Stress Disorder (PTSD). With PTSD affecting approximately one in 10 people in the UK, the research aims to evaluate if CWI can complement existing mental health treatments for this condition.
The study, led by Dr. Denise Hill, Associate Professor of Applied Sport Psychology at Swansea University, involves 16 participants from the Veterans RV Swansea Community group. These individuals, diagnosed with PTSD, engage in cold-water dipping and swimming sessions at Caswell Bay, Gower. The research seeks to establish the impact of regular cold-water immersion on PTSD symptoms.
Dr. Hill highlighted the importance of the study, stating, "With at least eight per cent of UK veterans diagnosed with PTSD annually, the condition presents significant economic, personal, and social challenges. While other studies have highlighted the benefits of cold water therapy, ours seeks to establish whether regular cold-water immersion can reduce PTSD symptoms specifically, and serve as an accessible and acceptable supplement to traditional mental health treatments."
Participants self-administer saliva samples to assess cortisol levels, which are indicators of stress, both before and during the study period. Following each weekly cold-water session, they complete questionnaires evaluating their wellbeing, depression, and PTSD symptoms. Initial findings suggest positive impacts of cold-water immersion on PTSD symptoms among the participants.
Phil Jones, a former Royal Marines Commando participating in the study, expressed optimism about its potential outcomes. He stated, "For years, I’ve practiced cold-water immersion to support my mental health and overall wellbeing, so I was excited to take part in this study alongside the veterans’ group I support. My ultimate goal has always been to help more veterans struggling with PTSD, and it’s been incredible to witness firsthand the physical and mental benefits this practice has had on those new to it."
Dr. Hill concluded by emphasizing the significance of the research: “This study represents an important first step in understanding whether CWI can serve as a complementary therapy for veterans diagnosed with PTSD. If successful, the findings should pave the way for further research, and if cold water immersion is deemed to be effective, the development of new, accessible treatment pathways for those with the condition."
