Understanding Cryotherapy: A Comprehensive Guide
Cryotherapy, a therapeutic technique involving exposure to extremely cold temperatures, has gained prominence in the fields of physical therapy, sports medicine, and wellness. This brief yet impactful treatment aims to harness the body’s natural response to cold, facilitating healing, reducing inflammation, and enhancing overall well-being. At Rebound Rehabilitation in St. Augustine, our team uses the many benefits it offers to ensure our patients get the best possible outcomes.
What is Cryotherapy? Understanding the Basics
Cryotherapy, derived from the Greek words “cryo,” meaning cold, and “therapy,” meaning treatment, is a method where the body is exposed to extremely cold temperatures for a short duration, typically between 2 to 4 minutes. Unlike localized cold treatments that target specific body parts, whole-body cryotherapy involves:
- Exposing the entire body to cold air in a controlled environment.
- Promoting a systemic response that encompasses pain relief.
- Reduced inflammation.
- Improved recovery processes.

What is SubZero localized (targeted) cryotherapy?
America Cryo’s Subzero handheld works by delivering short bursts of -110F carbon dioxide that drops skin temperature 59 degrees in 30 seconds, initiating a process called thermal shock.
Sports recovery and readiness (reduce pain & inflammation) Spas also are tapping localized cryotherapy’s other benefits— quick pain relief and reduction of swelling and inflammation— to provide packages of services to whole teams of athletes, 10 to 20 athletes at a time, for whole seasons of play.
Subzero: It’s the OG
First introduced in France in 2001, Subzero is the original targeted cryotherapy handheld, trusted by more than 10,000 spas, cryo centers, physical therapists and chiropractors around the world.
How Does Cryotherapy Work? Exploring the Science
The principle behind cryotherapy is to induce a controlled shock to the body, triggering various physiological responses. Cold exposure helps significantly reduce the sensation of pain and decreases blood flow to areas of inflammation. Moreover, the process stimulates the soft tissues in a manner similar to massage, enhancing mobility without the discomfort associated with prolonged cold exposure. The brief duration of the treatment ensures that the body’s core temperature remains stable, making the process both safe and effective.
How SubZero Cryotherapy Works:
The subzero cryotherapy machine uses pressurized CO2 gas to target a local area of the body and cause “thermal shock.” The sudden decrease in temperature rapidly activates the body’s healing response, and this is where cryotherapy’s benefits really shine. Within minutes after treatment, your body is responding to the thermal shock and relaxing your muscles, moving fresh blood and nutrients to the treated area, and reducing pain signals. You’ll be amazed how quickly cryotherapy treatment can reduce your pain and speed your recovery!

Cryotherapy offers a multitude of benefits, validated by both anecdotal evidence and scientific research:
Cryotherapy offers a multitude of benefits, validated by both anecdotal evidence and scientific research:
- Pain and Inflammation Reduction: By decreasing blood flow to inflamed areas, cryotherapy effectively reduces pain and swelling, aiding in managing chronic conditions and post-exercise recovery.
- Accelerated Recovery: Athletes and active individuals benefit from cryotherapy’s ability to reduce recovery time, allowing for more efficient training and performance.
- Sleep Quality Improvement: The treatment has been linked to enhanced sleep patterns, contributing to better rest and faster recovery
- Skin Health Enhancement: Exposure to cold temperatures can stimulate collagen production, improving skin elasticity and condition.
- Mood and Energy Boost:Cryotherapy can trigger the release of endorphins, boosting mood and energy levels and thereby enhancing overall well-being.

SubZero Cryotherapy Principal Effects
- Muscle Relaxant: Cryotherapy slows down nerve firing to help stop muscle spasm and improve pain and healing.
- Anti-Inflammatory: Treatment increases healthy blood flow, reduces swelling, and can prevent further tissue injury.
- Analgesic: Targeted cold reduces pain – simple, safe, and fast.
- Vasomotor: The Subzero promotes healthy blood flow and can reduce damaging blood vessel constriction.
