What Is The Difference Between A Whole-Body Cryo Chamber And A Cryo Sauna?

Local cold therapy for muscle and joint sprains has been extensively used for many years. However, more recently, whole-body cryotherapy has been widely used in sports medicine. Whole-body cryotherapy involves a brief exposure of up to four minutes at temperatures as low as -140 degrees Celsius.
By rapidly cooling the skin the cold exposure in a cryo chamber causes the blood vessels in the skin and muscles to narrow. This reduces the temperature of the muscles which slows cell metabolism and promotes muscle recovery. It also reduces muscle soreness and is thought to do so through activation of cold receptors that promote pain relief. The effect of the narrowing of blood vessels on the surface of the body is to increase blood flow at the core. This leads to activation of the parasympathetic nervous system, the rest and digest aspect of the nervous system. Elevated parasympathetic activity is associated with greater health and wellbeing.
What is a Cryo Sauna?
Unlike in a cryo chamber, in cryo saunas also called cryo cabins the whole body is not inside the cabin (the head is outside). These cabins are open-ended metal tubes. In the cryo saunas the head is outside the cabin. The cooling in a cryo sauna is delivered through direct exposure to liquid nitrogen. This allows free nitrogen vapour into the cryosauna, which could potentially be very hazardous, causing asphyxia.
What is a Cryo Chamber?
In contrast to a cryo sauna, in a whole-body cryo chamber, there is no exposure to liquid nitrogen. Instead, the chamber is cooled either through electricity or indirectly by liquid nitrogen. Generally, liquid nitrogen chambers can achieve colder temperatures. Most of the medical studies into whole-body cryo chambers have been done at -110. Only a few electric cryo chambers can get down to this temperature. In the liquid nitrogen chambers, the liquid nitrogen is pumped into pipes inside the walls of the chamber. This supercools the surrounding fresh air which is then pumped into the chamber.
Because the head is inside the whole-body cryo chamber it is more effective at cooling the skin than a cryo sauna. Whole-body cryotherapy has also been found to be more effective at activating the parasympathetic nervous system than cryo saunas.
If you are nervous about having your head inside the chamber, our safe liquid nitrogen cooled whole-body cryo chamber has an adjustable window so you can chat with your trained operator. The door is closed but not locked so you always feel in control when you are in the chamber.

People enthusiastic about whole-body cryotherapy as a natural and holistic wellness treatment often confuse the concepts of a cryosauna and a cryo chamber. With good reason, as their purpose is the same. Both a cryousauna and a cryo chamber are modern cryotherapy machines designed to administer whole-body cryogenic treatments. Still, there are significant differences between the two cryotherapy devices. Lets briefly go through the common features and distinctions between cryosaunas and cryo chambers.
A cryosauna is an open-top tube with a door and an elevator for customer positioning. Cryosaunas run on liquid nitrogen, which produces lower temperatures (down to -170/-180) as compared to an electric cryo chamber.
A cryo chamber is a walk-in enclosed space cooled by electricity or liquid nitrogen. Nitrogen-cooled machines feature indirect injection in a closed-loop contour. Both electric and nitrogen-run configurations provide breathable air inside the cabin and treatment temperatures down to -110. The main difference between the two machines is their design, open-top, with the customers head staying out, or enclosed, for the full-body experience.
Lets list the other differences.

Cryosaunas are relatively compact, with some models requiring only 1 square meter to install. That means lower delivery and installation costs and a smaller footprint. Also, the compact size translates into low nitrogen and power consumption. In addition, due to their size and comparatively straightforward design, cryosaunas usually come with an affordable price tag.

On the other hand, cryo chambers are usually more complex design-wise. Electric chambers require an electric generator to cool down the cabin and may also include a cooling plant for the generator which means they need more space. Even individual cryo chambers are typically bigger than cryosaunas. With two- or three-person cryo chambers, this difference in footprint is even more prominent. All this results in a higher initial equipment cost, especially for electric chambers. Delivery and installation costs also tend to be high, but less so in nitrogen-cooled machines.

In an open-top cryosauna, the client is lifted inside the cabin so that only his body is cooled while the head stays outside. A client can speak to an operator or other clients during a session for a more comfortable experience. Open-top design is a critical factor for people who fear enclosed spaces. Group configurations for open-top cryosaunas do not exist.
In a cryo chamber, the customer walks into a cooled room, thus exposing their entire body to subzero temperatures. There are individual and group chambers where several people can take a session at the same time.
In a cryo chamber, the temperature usually doesnt exceed -110°C (-230°F), while in a cryosauna, it can go down to about -170°C (-274°F). That means that in a cryosauna, your body is exposed to a higher positive stress, and the effect of a cryotherapy session will be more pronounced. Or it will take less time to achieve the same effect as in a cryo chamber.
For a cryotherapy session, you need to leave uncovered as much skin as possible but protect vulnerable body parts. In a cryosauna, wear warm footwear and underwear, preferably made of natural fabric, e.g., cotton. Gloves are used only together with an over-the-cabin cover. Otherwise, hands stay at the top of the cabin, making gloves redundant. As for a cryo chamber, in addition to the clothes listed above gloves are a must you will need to put on a beanie or earmuffs and respiratory mask to protect your head, ears, and airways.
As cryosaunas and cryochambers use different modes to produce cryogenic temperatures, their running and maintenance costs differ as well.
As for the running costs, with an electric cryochamber, expect your electricity bills to go up, while a cryosauna or a nitrogen-cooled cryochamber will hardly affect them, as they consume 1.5 kW at most. Nitrogen-cooled cryo chambers, in addition, need liquid nitrogen, and the amounts are double or triple compared to cryosaunas, depending on the brand and whether its a two-person, three-person, or some other group configuration.
Both cryosaunas and nitrogen-cooled cryochambers are low-maintenance. Electric cryochambers require professional maintenance every year.
All the factors above can influence your cost of a cryo session and the number of potential clients, thus affecting your return on investment. Cryo chambers are usually not advisable if your daily customer flow is below 30 to 40 people. On the other hand, open-top cryosaunas can serve up to 90 people daily, catering to a wider range of businesses.
