Floatation’s Hidden Power
Bottom line: Floatation-REST may alter consciousness without drugs. Imagine being suspended in a warm, dark tank, your body buoyant and free from sensation. For some, this experience is not just relaxing, but a gateway to an altered state of consciousness. This concept may sound like the realm of psychedelics, but what if a similar effect could be achieved without any substances?
In a preprint study published on PsyArXiv, researchers explored the effects of Floatation-REST on individuals with anxiety and depression. The study involved 75 participants, who were assigned to either Floatation-REST sessions with prescribed or preferred scheduling, or a zero-gravity chair comparison condition. The results showed that Floatation-REST was associated with increased interoceptive awareness and an altered state of consciousness, characterized by feelings of oceanic boundlessness, disembodiment, and unity.

The Science of Floatation-REST
Floatation-REST is a technique that involves floating in a tank filled with a solution of water and Epsom salt, which allows the body to float effortlessly. The tank is designed to reduce sensory input, creating an environment that is neutral in terms of temperature, sound, and light. This reduction in sensory stimulation can lead to a range of effects, including deep relaxation, reduced pain, and increased feelings of well-being.
The study used the 5-Dimensional Altered States of Consciousness Rating Scale to assess the effects of Floatation-REST on consciousness. The results showed that participants who underwent Floatation-REST reported increased feelings of oceanic boundlessness, disembodiment, and unity, which the researchers referred to as “aquahenosis.” This state is characterized by a sense of connection to the universe, a feeling of being one with everything, and a loss of boundaries between the self and the external world.
Comparing Floatation-REST to Psychedelics
The effects of Floatation-REST on consciousness are reminiscent of those reported for psilocybin and ketamine, two substances known for their ability to induce altered states of consciousness. The study found that the experiential profiles of Floatation-REST overlapped with those reported for these substances, particularly along the boundary-dissolution dimension. This suggests that Floatation-REST may be a non-pharmacological method for inducing specific altered states of consciousness, similar to those achieved with psychedelics.
The Importance of Oceanic Boundlessness
The study highlighted the importance of oceanic boundlessness as a mediator of the float-induced changes in positive affect. Oceanic boundlessness refers to the feeling of being connected to the universe, and of being one with everything. This feeling is often reported by individuals who have used psychedelics, and is associated with increased feelings of well-being and life satisfaction.
The study found that participants who reported higher levels of oceanic boundlessness also reported greater improvements in positive affect, suggesting that this dimension is a key component of the therapeutic effects of Floatation-REST.
