Whole-body cryotherapy involves exposing the body to ultra-low temperatures, typically ranging from -110°C to -140°C, for a brief period of two to four minutes. This controlled exposure triggers a systemic anti-inflammatory response and promotes physical recovery. Proper preparation is necessary to ensure safety and maximize therapeutic benefits, involving medical clearance, skin readiness, protective gear, and optimizing your internal state.
Prioritize Medical Clearance
A thorough review of your health history is a non-negotiable first step. Facilities require clients to complete a health questionnaire and sign a waiver confirming they have no contraindications. The intense cold causes a rapid, temporary constriction of peripheral blood vessels, which is dangerous for individuals with pre-existing cardiovascular conditions. Absolute contraindications include severe, uncontrolled hypertension, recent heart attack or stroke, or having a pacemaker. Other conditions barring participation are symptomatic cardiovascular disease, deep vein thrombosis (DVT), Raynaud’s phenomenon, severe anemia, cold-induced urticaria, and pregnancy. Consult a medical professional if you have any doubt regarding an existing health condition.
Immediate Skin and Moisture Preparation
The skin’s condition immediately before entering the chamber is a primary factor in preventing cold-related injury. The skin must be completely dry, as any moisture can instantly freeze in the ultra-cold environment, leading to localized cold burns or frostbite.
Avoid applying topical products (lotions, oils, creams, perfumes) on the day of your session, as these can trap moisture. All metal items, including jewelry and piercings, must be removed because metal conducts cold rapidly and can cause severe contact injury. Also, avoid shaving immediately before the session, as micro-abrasions become highly sensitive when exposed to the intense cold.
Required Attire and Protective Gear
Wearing the appropriate attire is essential for protecting vulnerable body parts during the brief exposure to sub-zero temperatures. Clients typically wear minimal, dry clothing, such as cotton underwear, shorts, or a sports bra, to expose as much skin as possible. Wet clothing poses a significant risk of freezing.
The facility provides mandatory protective gear to cover the extremities, which are most susceptible to frostbite. This gear includes thermal gloves, dry socks, and specialized slippers or boots. If the head is exposed, a headband or ear protection is required, and a face mask may be provided to protect the face and airways.
Scheduling and Internal Preparation
Optimizing your internal state and managing logistics will contribute to a more effective session. Be well-hydrated in the hours leading up to your appointment to support circulation, but avoid drinking excessive amounts of fluid immediately before entering the chamber.
Do not enter the session on a completely empty stomach, but consuming a heavy meal beforehand is discouraged. A light snack is acceptable, though some advise against high-sugar foods or carbohydrates in the two to four hours prior. Avoid intense physical exercise or anything causing heavy sweating immediately before the session to ensure dry skin. Mental preparation involves setting the expectation that the session lasts only two to three minutes, allowing you to focus on steady breathing and maintaining a calm demeanor.
