Abstract

Background and purpose: Flotation Restricted Environmental Stimulation Therapy (REST) has gained popularity since the 1980s, especially with the rise of modern Epsom salt flotation tanks. While clinical studies support its benefits for stress, pain, and mental health conditions, little is known about the motivations, experiences, and insights of regular users. This study aimed to explore these aspects. Materials and Methods: An online questionnaire was distributed between 6 January and 30 April 2023. The 23 questions covered demographics, flotation habits (frequency, duration), perceived benefits, side effects, and research priorities. Respondents were also invited to propose future research areas. Results: Eighty-three participants (63.4% female), primarily from the UK (n=52), responded. Most were aged 26–55 years. While 70% desired to float 1–7 times weekly, actual use was typically 1–3 times monthly. Sessions lasted 30–60 minutes (65.1%) or 61–90 minutes (28.9%). Most had floated regularly for 3–5 years. Commonly reported benefits included relaxation (91.6%), stress reduction (77.1%), and sensory disconnection (67.5%), along with improved mental clarity (56.6%), sleep (55.4%), and reduced anxiety (47.0%) and pain (33.7%). Notably, 53.0% also reported personal growth and spiritual benefits. Effects lasted 1–4 days for most. Minor side effects were noted in 25.5% of respondents. Research priorities included stress (84.1%), burnout and PTSD (both 73.2%), and anxiety (70.7%). Conclusion: Regular flotation users report substantial mental health and wellness benefits. Their strong interest in more frequent sessions and further research highlights the need for increased accessibility and scientific investigation into flotation REST’s therapeutic potential.
