The micro-phenomenology of Floatation-REST

Area of Science:

• Psychology
• Neuroscience
• Consciousness Studies

Background:

• Floatation-REST (Restricted Environmental Stimulation Therapy) involves sensory isolation in a dark, silent, Epsom salt-saturated water tank.
• Previous research suggests Floatation-REST has salubrious effects, particularly for mental health conditions.
• The positive outcomes of Floatation-REST may be linked to the induction of altered states of consciousness (ASC).

Purpose of the Study:

• To examine the generic structure of altered states of consciousness (ASC) experienced during Floatation-REST.
• To investigate the phenomenological characteristics of ASC within a sensory isolation context.

Main Methods:

• A micro-phenomenological study design was employed.
• Fourteen participants underwent a 60-minute Floatation-REST session.
• Semi-structured interviews were conducted post-session to capture the subjective experience of ASC.

Main Results:

• Participants reported experiencing four distinct phases during Floatation-REST: acclimatization, transition, ASC, and reorientation.
• The ASC phase was characterized by positive emotions, deep relaxation, loss of spatial/temporal orientation, and reduced sensory/cognitive input.
• The ASC experience developed gradually, with increasing intensity of its characteristics.

Conclusions:

• Floatation-REST reliably induces a specific structure of altered states of consciousness.
• The micro-phenomenological analysis provides insight into the subjective experience of sensory isolation.
• Findings suggest potential therapeutic applications for Floatation-REST, warranting further research.
