What Is Float Therapy (Flotation-REST)?
Sensory-deprivation float tank sessions to promote relaxation and recovery.
Overview
Float therapy (flotation-REST) uses buoyant salt water and reduced light and sound to create a low-stimulation relaxation setting. Small studies suggest short-term improvements in anxiety, stress, pain, or well-being for some participants, but samples are often small and evidence does not establish treatment of a medical or psychiatric disorder.
It is retained in Lifestyle Medicine as an optional relaxation service—not as a substitute for sleep care, psychotherapy, physical rehabilitation, or disease treatment.
Benefits
Deep relaxation and stress reduction without medication
Decreased muscle tension and joint loading during sessions
May improve sleep onset/quality and perceived recovery
Quiet environment that supports mindfulness and breathwork

Preparation
Avoid shaving/waxing and new tattoos for several days prior (salt may sting). Do not apply heavy lotions/hair products before floating. Eat a light meal 1–2 hours before; avoid large meals, caffeine, and alcohol pre-session. Bring contact lens case (if applicable).
Recovery & Aftercare
No downtime. You may feel relaxed or mildly drowsy; allow a transition period before driving if you are very sleepy. Moisturize skin and rehydrate after the session.
Risks & Considerations
Possible effects include skin or eye irritation, dizziness, nausea, anxiety, claustrophobia, and infection if sanitation is poor. Avoid with open wounds, contagious skin or gastrointestinal illness, intoxication, or uncontrolled seizures; ask a clinician about pregnancy or serious medical conditions. Float therapy is not emergency or psychiatric-crisis care.
