The Science of Floating
Dive into the research behind floatation therapy — from neuroscience to clinical studies.
Floatation therapy isn't just a wellness trend — it's backed by decades of scientific research.
The REST Principle
Floatation therapy is formally known as Restricted Environmental Stimulation Technique (REST). By dramatically reducing sensory input, the brain enters a unique state of deep relaxation with measurable physiological and psychological effects.
What Happens in Your Brain
Theta Brain Waves
During a float, the brain shifts from its normal waking state (beta waves) through relaxed alpha waves and into theta waves — the same brain state experienced during deep meditation and just before sleep. This state is associated with creativity, insight, and deep relaxation.
Default Mode Network
Research using fMRI scans has shown that floating affects the default mode network (DMN) — the brain network active during self-reflection. Floating appears to quiet the DMN, similar to the effects of experienced meditation.
Hormonal Changes
Cortisol Reduction
Multiple studies have measured significant drops in cortisol (the stress hormone) after floating. A 2018 study in PLOS ONE found a single float session reduced cortisol levels and blood pressure while improving mood.
Endorphin Release
The deep relaxation triggers the release of endorphins — the body's natural painkillers and mood elevators.
Dopamine & Serotonin
Research suggests floating may increase levels of dopamine and serotonin, neurotransmitters associated with pleasure, motivation, and emotional wellbeing.
Key Research Studies
The LIBR Float Clinic
Researchers at the Laureate Institute for Brain Research showed that floating significantly reduced anxiety — including in participants who had never tried floating before.
Swedish Pain Studies
A series of studies demonstrated that floating reduced chronic pain by up to 40% in patients with fibromyalgia, muscle tension, and stress-related pain.
Blood Pressure Research
A controlled study showed that regular floating over 7 weeks produced sustained reductions in both systolic and diastolic blood pressure.
The Magnesium Question
While many claim that magnesium is absorbed through the skin during floating, the scientific evidence is still emerging. A 2017 University of Birmingham study found that transdermal magnesium absorption is possible, though more research is needed.
Ongoing Research
Float Research Collective
The Float Research Collective is a 501(c)(3) nonprofit dedicated to advancing floatation-REST research. Their mission is to fund and promote clinical studies that establish floating as an accepted medical treatment — helping bridge the gap between anecdotal evidence and peer-reviewed science.
