The Science Behind Cryotherapy: Understanding How It Works

If you're an athlete or fitness enthusiast, you may have heard of cryotherapy as a trendy new way to enhance your performance and speed up recovery time. But how does this icy treatment actually work? In this blog post, we'll explore the science behind cryotherapy and explain the mechanisms that make it an effective tool for pain relief and improved overall health.


At its most basic level, cryotherapy involves exposing the body to extremely cold temperatures for a short period of time. This can be achieved in a number of ways, but the most common method is through the use of a cryotherapy chamber or sauna. During a typical cryotherapy session, a person will enter the chamber wearing minimal clothing and be exposed to temperatures ranging from -100 to -150 degrees Celsius for two to four minutes.


So how does exposure to these frigid temperatures benefit the body? The key lies in the way the body responds to extreme cold. When the body is exposed to such low temperatures, it enters a state of "cold shock," triggering a series of physiological responses designed to help it survive the harsh conditions.

One of the primary responses to cold shock is vasoconstriction or the narrowing of blood vessels. This causes blood to be redirected away from the extremities and towards the core of the body in order to maintain body temperature and protect vital organs. As a result, the heart rate and blood pressure may temporarily increase during a cryotherapy session.


Once the session is over and the body returns to normal temperatures, the opposite occurs: the blood vessels dilate and blood flow is increased throughout the body. This sudden increase in blood flow is believed to stimulate the body's natural healing processes, as well as deliver oxygen and nutrients to tissues and organs.

Reduce Inflammation

But that's not all. Cryotherapy is also thought to reduce inflammation and pain through a process known as cryoanalgesia. This occurs when the cold temperatures cause a numbing effect on the skin and underlying tissues, reducing nerve conduction and temporarily blocking pain signals from reaching the brain.


Endorphin Release

In addition, the cold temperatures can also trigger the release of endorphins, the body's natural painkillers. Endorphins are responsible for the "runner's high" that many athletes experience after a workout, and they can help alleviate pain and improve mood.

Improved Athletic Performance

Cryotherapy may also be beneficial for improving overall athletic performance. The cold temperatures have been shown to increase metabolism, causing the body to burn more calories in the hours following a session. This can help athletes lose weight and improve their body composition.

Increased Bloodflow

Furthermore, the increase in blood flow and delivery of oxygen and nutrients to tissues can also help improve muscle recovery and reduce soreness. This means athletes may be able to train harder and more frequently without risking injury or burnout.



While cryotherapy has been touted as a cure-all for a wide range of health conditions, it's important to note that the scientific evidence supporting its efficacy is still somewhat limited. However, early studies have shown promising results for conditions such as rheumatoid arthritis, multiple sclerosis, and fibromyalgia.


In addition, many athletes and fitness enthusiasts swear by the benefits of cryotherapy for reducing soreness, improving recovery time, and enhancing overall athletic performance. Whether you're a weekend warrior or a professional athlete, cryotherapy may be worth considering as a complement to your training regimen.


So there you have it - the science behind our New Jersey cryotherapy. While it may seem like a daunting experience to subject yourself to such extreme temperatures, the potential benefits may be well worth it. If you're interested in trying cryotherapy for yourself, be sure to consult with a qualified healthcare professional to determine if it's safe for you and your specific health needs.
