Aquahenosis: A non-pharmacological altered state of consciousness induced by Floatation-REST in individuals with anxiety and depression

PsyArXiv June 10, 2026 Theo Tobel, Aidan Cone, Emily Choquette et al. preprint

Floatation-REST (Reduced Environmental Stimulation Therapy) systematically alters sensory and bodily input by combining neutral buoyancy, thermal and proprioceptive neutrality, attenuation of exteroceptive stimulation, and enhancement of cardiorespiratory signaling to the brain. Here we examined whether this non-pharmacological sensory perturbation induces altered states of consciousness and...

Induction of altered states of consciousness during Floatation-REST is associated with the dissolution of body boundaries and the distortion of subjective time.

Floatation-REST (Reduced Environmental Stimulation Therapy) minimizes stimulation of the nervous system by immersing subjects in an environment without sound or light while they effortlessly float in thermoneutral water supersaturated with Epsom salt. Here we investigated the relationship between altered states of consciousness (ASC) and its association with the affective changes induced by...

Taking the body off the mind: Decreased functional connectivity between somatomotor and default‐mode networks following Floatation‐REST

Human Brain Mapping April 9, 2021 Obada Al Zoubi, Masaya Misaki, Jerzy Bodurka et al. 39 citations

Abstract Floatation‐Reduced Environmental Stimulation Therapy (REST) is a procedure that reduces stimulation of the human nervous system by minimizing sensory signals from visual, auditory, olfactory, gustatory, thermal, tactile, vestibular, gravitational, and proprioceptive channels, in addition to minimizing musculoskeletal movement and speech. Initial research has found that Floatation‐REST...
