Cold-water immersion
Cold plunge: what it does, what to expect & where to try it
Cold plunge, also called cold-water immersion, involves submerging the body in cold water — typically between 45°F and 59°F (7–15°C) — for a set duration ranging from two to fifteen minutes. Practiced for centuries and widely popularized by researchers and athletes, it has become a staple at recovery studios across the US.
Cold plunge, also called cold-water immersion, involves submerging the body in cold water — typically between 45°F and 59°F (7–15°C) — for a set duration ranging from two to fifteen minutes. Practiced for centuries and widely popularized by researchers and athletes, it has become a staple at recovery studios across the US. In a studio setting you'll find purpose-built tubs with chilled, filtered, recirculating water held at a precise temperature — a significant upgrade over improvised home setups. Cold plunge is primarily sought for post-exercise muscle recovery, mood enhancement, and general stress adaptation. It is frequently paired with infrared sauna or hot tub as part of a contrast therapy circuit, and is often combined with compression therapy or red light therapy in the same visit. Viral wellness content and high-profile recovery protocols have driven rapid demand growth for professional cold-plunge facilities that offer a safe, clean, and temperature-controlled environment.
How cold plunge works
Cold water immersion triggers vasoconstriction — narrowing of surface blood vessels — followed by vasodilation as the body rewarms, which may help clear metabolic waste from muscle tissue. Exposure to cold also activates the sympathetic nervous system, stimulating release of norepinephrine, which research associates with improved mood and alertness. Studies suggest repeated cold exposure can upregulate cold-shock proteins and may support autonomic nervous system resilience over time, though optimal temperature and duration protocols are still being refined.
Is cold plunge right for you?
A quick, goal-based fit guide — who tends to get the most from cold plunge, and when it's worth a word with a professional first. This is wellness guidance, not medical advice.
Often a great fit if…
Cold plunge is popular with athletes and active individuals managing post-workout soreness, as well as people seeking a natural mood boost, stress adaptation, or mental resilience tool. Anyone curious about deliberate cold exposure as a wellness practice will find a studio cold plunge is the cleanest and most controlled way to start.
Worth a quick check first if…
People with cardiovascular disease, Raynaud's disease, uncontrolled hypertension, or who are pregnant should consult a clinician before cold plunging. Those who are acutely ill or have open wounds should avoid cold-water immersion until cleared by a healthcare provider.
What a first session feels like
A typical studio session lasts two to ten minutes at water temperatures between 45°F and 59°F. The first thirty seconds are the most challenging — an intense cold shock and strong urge to exit — which subsides as breathing normalizes and the body adjusts. Most people notice a sustained energy lift and sense of calm within minutes of finishing.

Equipment & brands for Cold plunge
The equipment brands that power cold plunge at studios in our directory.
Morozko Forge
Ice baths & cold plunge
Morozko Forge builds high-performance ice baths and cold plunge units in the United States. The company uses ozone-based water treatment rather than chlorine, positioning the system as cleaner for immersion. Units are designed to reach and maintain colder temperatures than many competing consumer cold plunge products. Morozko targets serious home athletes and biohackers who want sustained very cold water temperatures for regular practice. The price point is firmly premium, and the product is also used in some commercial wellness and training environments.
Renu Therapy
Cold plunge & sauna
Renu Therapy makes cold plunge tubs and infrared sauna cabins designed for home and light commercial use. Cold plunge units use stainless steel construction with integrated active chilling, and the product range includes models suited to indoor and outdoor installation. The sauna line adds infrared options, allowing the brand to serve customers who want contrast therapy pairing in the same purchase. Renu Therapy targets health-focused consumers and small commercial operators, positioning itself in the mid-to-premium tier of the home recovery equipment market.
BlueCube Baths
Cold plunge
BlueCube Baths manufactures cold plunge tubs in Redmond, Oregon, using 316L stainless steel with made-to-order fabrication. The lineup spans compact single-user residential models and larger commercial-grade units suited to wellness studios and athletic facilities. All tubs integrate active chilling systems and can be configured to various dimensions. The brand occupies the premium end of the cold plunge market, appealing to serious home users and commercial operators who prioritize US craftsmanship, material quality, and a low-maintenance setup over lower-cost alternatives.
Ice Barrel
Cold plunge
Ice Barrel sells vertical cold-water immersion barrels designed for home use. The barrel format is compact, requiring less floor space than horizontal tub designs, and is suited for outdoor or garage placement. Standard units use passive cooling without a built-in chiller, making them accessible at a lower price point than powered cold plunge systems. Ice Barrel targets individual wellness users seeking a durable, simple cold plunge solution for daily practice, rather than commercial studios or facilities with high-throughput client needs.
Plunge
Cold plunge systems
Plunge makes cold plunge systems sold primarily to residential users and small commercial operators in the United States. Units include integrated chilling systems capable of maintaining low water temperatures year-round, and are available in standard and pro versions at varying price points. Plunge is one of the more recognized brands in the direct-to-consumer cold plunge segment, offering features including filtration and temperature control in a freestanding format. The brand targets health-focused homeowners and light commercial settings such as small gyms and studios.

Frequently asked questions
How long should I stay in a cold plunge?
Most studios recommend starting with 2–4 minutes and building up gradually. Shorter sessions at colder temperatures (45–50°F) can be as effective as longer sessions at milder temperatures; exceeding 10–15 minutes is rarely necessary for wellness purposes.
Should I cold plunge before or after a workout?
Most people cold plunge after exercise to aid muscle recovery. Some research suggests cold exposure immediately after strength training may blunt muscle adaptation — if hypertrophy is your goal, you may want to wait at least an hour post-lifting.
How often should I cold plunge?
Research suggests 2–4 sessions per week provides meaningful recovery and mood benefit for most people. Consistent exposure over weeks matters more than daily frequency.
What happens to your body in a cold plunge?
Cold water causes blood vessels to constrict rapidly, slowing flow to the skin and extremities while maintaining core temperature. As you rewarm, vessels dilate and circulation surges. Simultaneously, the sympathetic nervous system releases norepinephrine — a hormone linked to alertness and improved mood.
Is a cold plunge the same as an ice bath?
Functionally similar — both involve cold-water immersion. A studio cold plunge tub maintains precise temperature control and uses filtered, recirculating water, whereas an ice bath is improvised with ice and tap water. Studio plunges are consistently cleaner and more temperature-stable.
