Key Takeaway
Six sessions of flotation-REST were safe and feasible in anxious and depressed individuals, with pool-based and tank-based formats both showing acute anxiolytic effects
Summary
This single-blind randomized trial examined the safety and feasibility of repeated flotation-REST in 75 individuals with anxiety and depression. Participants completed six sessions in different formats: pool-REST, pool-REST preferred, or chair-REST (active comparator). The study established that repeated flotation sessions are safe and well-tolerated in clinical populations.
Methods
Single-blind RCT with 75 individuals with anxiety and depression randomized to pool-REST, pool-REST preferred, or chair-REST (active comparator). Six sessions completed. Assessed safety, feasibility, and acute anxiolytic/antidepressant effects.
Key Results
Flotation-REST was safe and well-tolerated across all sessions. Both pool-REST formats showed acute reductions in anxiety and depression. Feasibility was confirmed for repeated intervention use in clinical populations.

Limitations
Single-blind design. Active comparator (chair-REST) not a true placebo. Relatively small sample per group. Primarily assessed safety and feasibility rather than efficacy. Short-term outcomes only.
