Float Therapy — Sensory Deprivation Pod

Float therapy at Freeze & Float immerses guests in one of five private pods filled with body-temperature water saturated with 1,000 lbs of Epsom salt. The buoyancy renders the body completely weightless, removing gravitational pressure from joints and the spine while encouraging deep muscular relaxation. Sessions run 60 minutes and include a private suite with shower and changing area. The sensory deprivation environment — zero light, near-silence — promotes a meditative state that may support stress reduction, improved sleep, and mental clarity.

Floatation therapy, also referred to as REST (Restricted Environmental Stimulation Therapy), is the centrepiece offering at Freeze & Float Spa in Chicago's River North neighbourhood. The experience takes place in a purpose-built pod filled with body-temperature water (approximately 93.5°F / 34°C) that has been saturated with roughly 1,000 lbs of pharmaceutical-grade Epsom salt — magnesium sulfate — creating a specific gravity high enough to make any body effortlessly buoyant. The float environment at 371 W Ontario Street is engineered for complete sensory reduction. Each of the spa's five private pods can be darkened to total blackout and quieted to near-silence, removing the two dominant sensory inputs that ordinarily keep the nervous system active. In this environment, the brain rapidly shifts toward slower brainwave states associated with deep relaxation and early-stage sleep, while physical tension dissipates as muscles no longer need to counteract gravity. The Epsom salt medium delivers a secondary benefit: transdermal absorption of magnesium, a mineral that many adults consume in insufficient quantities. Magnesium plays roles in muscle contraction and relaxation, nerve transmission, and sleep regulation. Athletes in particular have used floatation therapy as a recovery tool, citing reduced next-day soreness and faster return to training. Each float session at Freeze & Float is booked for 60 minutes and is housed in a fully private suite equipped with a shower for pre- and post-float rinsing, a changing area, and amenities to support the experience. First-time visitors are offered an introductory rate and receive a full orientation briefing from staff. The River North location offers convenient access from the Loop, Streeterville, Gold Coast, and the Near North Side, making it one of the most accessible float destinations in Chicagoland.
