If you’re comparing cryotherapy chambers for a gym, spa, recovery center, or wellness business, you’ll quickly run into some extreme numbers.
-100°F. -185°F. Sometimes even lower.
It’s easy to assume the chamber with the lowest number delivers the strongest session. But cryotherapy temperatures are not always measured or reported in the same way.
And more importantly, temperature alone does not tell you how effectively a chamber removes heat from the body.
That’s why, if you’re investing in a cryotherapy chamber, there’s a better question to ask:
How does the system actually cool the body, and what kind of experience will it consistently deliver to your clients?
The number on the spec sheet doesn’t tell the whole story
Different cryotherapy technologies create cold in different ways.
Some use liquid nitrogen. Others use mechanical refrigeration. Some rely heavily on very cold air, while others combine refrigeration with strong airflow.
Even the temperature itself can refer to different things depending on the manufacturer: the cooling source, a point inside the chamber, the air surrounding the user, or a perceived-temperature rating.
That difference is not theoretical.
A 2021 international consensus paper on whole-body cryostimulation reported manufacturer-stated temperatures ranging from -110°C to -195°C for cryosaunas, -60°C to -160°C for static whole-body chambers, and -40°C to -60°C for forced-convection systems. Researchers measuring conditions during actual exposures found temperatures around users that could be much less extreme.
For a buyer, the takeaway is simple:
Before comparing two temperature numbers, first ask what those numbers are measuring.
What actually makes a cryotherapy session feel cold?
This is where the engineering gets more useful.
When Evan Kuklinski, Artica Systems’ Co-Founder and Chief Engineer, explains cooling performance, he focuses on three interacting factors: temperature difference, heat extraction through airflow, and the amount of exposed surface the cold air can reach. That framework is central to the Artica presentation on cooling performance.
Temperature difference
Your skin is warm. The air around it is colder.
The greater that difference, the greater the potential for heat to move away from the body.
This is the part everyone understands, and it is why cryotherapy manufacturers talk so much about how cold their machines get.
But it is only one part of the cooling process.
Airflow
Think about a 62°F day.
With no wind, it may feel cool but comfortable.
Now add strong wind.
The thermometer still reads 62°F, but the experience changes immediately.
Your skin constantly warms a thin layer of air sitting directly against it. In heat-transfer engineering, this is known as the boundary layer.
When that air stays relatively still, it provides some resistance to further heat loss.
Move it away and replace it continuously with colder air, and heat leaves the body faster.
This is why airflow can dramatically change the intensity of a cryotherapy session without requiring the air temperature itself to fall by the same amount.
And this principle has been tested outside Artica.
A controlled 2017 study of a mechanically refrigerated, forced-convection cryotherapy chamber found substantial skin cooling during a three-minute exposure at -40°C. The researchers specifically discussed the role of airflow in reducing the warm boundary layer around the body.
The study did not test an Artica chamber. It supports the underlying heat-transfer principle.
Exposed surface
The third factor is simple: cold air can only remove heat effectively from the areas it reaches.
Clothing, body position, airflow direction, and the design of the chamber all influence how much exposed skin actually interacts with moving cold air.
This is why chamber design matters.
Creating one extremely cold point inside a machine is different from distributing cooling across the user.
So does colder cryotherapy mean better cryotherapy?
Not necessarily.
Research comparing cryostimulation technologies shows why that assumption is too simple.
The same 2021 consensus paper summarized average skin-temperature changes after approximately three-minute exposures of around 8°C in cryosauna studies, 11°C in static whole-body chamber studies, and 14°C in forced-convection chamber studies. These were different studies using different systems, so they should not be treated as a direct product ranking.
Mean skin-temperature reduction after about three minutes
Across the studies reviewed, more extreme advertised temperatures did not consistently produce greater skin cooling.
Mean skin-temperature reduction reported across studies summarized by Bouzigon et al., 2021. Different systems and protocols.
But they do show something useful for anyone buying equipment:
The most extreme advertised temperature did not automatically correspond to the greatest measured skin cooling.
That is why we prefer to talk about cooling performance rather than cold temperature alone.
How Artica approaches cooling
Artica’s engineering approach is built around using the complete cooling environment rather than chasing one number.
Active Cooling is the foundation. The goal is to move heat away from the body efficiently using electric refrigeration, controlled airflow, and chamber design.
The Vortex makes that philosophy particularly visible.
Instead of relying only on extreme air temperature, the Vortex uses a 20-fan airflow system to create its characteristic high-intensity wind-chill experience.
Walk into a Vortex and the sensation is intentionally closer to standing in a controlled wind tunnel than standing in a still freezer.
That is not just an experience choice.
The airflow is part of the cooling mechanism.
The Ethos takes a different approach. It has more cooling capacity and gives operators greater flexibility in how the session feels, from stronger wind chill to a quieter, lower-airflow experience. Artica’s sales and engineering materials position Vortex around intensity and Ethos around a combination of capacity and experience flexibility.
One temperature also doesn’t fit every client
There is another reason not to obsess over one perfect setting.
People respond to cold differently.
Body composition, previous exposure, individual cold tolerance, and other factors influence how quickly someone cools and how intense a session feels.
A 2024 controlled study, for example, found different skin-cooling responses depending on BMI even when participants were exposed to the same whole-body cryostimulation protocol. The authors concluded that appropriate exposure may need to vary between individuals.
This matters in a real business.
A performance-focused gym may serve athletes who actively want a hard, intense session.
A wellness center may have clients who want cryotherapy but prefer a more controlled experience.
A recovery studio may serve both within the same day.
That is why Artica developed BreezeLink™.
Instead of forcing every user into the same preset experience, BreezeLink lets the person inside the chamber adjust session intensity in real time. The control is inside the chamber, so they do not need to stop the session or ask staff to change it for them.
For the owner, that means one chamber can accommodate a broader range of client preferences without adding more work for the team.
How cold do Artica cryotherapy chambers feel?
Artica uses perceived-temperature ratings to describe the intensity of each system.
These are not presented as direct ambient-air thermometer readings.
Controlled, plug-and-play electric cooling.
High-airflow, strong wind-chill experience.
High-capacity system with more control over airflow and experience.
The -90°F, -100°F, and -185°F ratings are the values in Artica’s current product comparison specification. The point of the range is not to decide that Ethos is automatically “better” because its number is lower. Element, Vortex, and Ethos solve different operational problems. Element prioritizes installation simplicity. Vortex prioritizes a powerful single-user airflow experience. Ethos adds capacity and greater flexibility in how sessions are delivered. That distinction is much more useful when you are choosing equipment for a business.

Find the Right ChamberWhat should you compare before buying a cryotherapy chamber?
The Artica presentation identifies six things that matter when choosing a commercial cryotherapy system: cold performance, personalization, automation and self-service, service, cost efficiency, and the ability to scale.
Here is what those criteria mean in practice:
Ask where the advertised temperature is measured, how air moves around the user, and what evidence the manufacturer can provide about real cooling performance.
Think about who will actually use the machine. A chamber designed only around maximum intensity may not suit a spa clientele. A very mild experience may disappoint performance-focused customers. Look at how much control users have over the session.
A three-minute service can become labor-intensive if a staff member has to start the machine, control every session, manage cooldowns, and shut everything down manually. Artica’s system architecture includes automated scheduling, in-chamber controls, monitoring, and other features designed around lower-touch operation.
Downtime matters more than an impressive spec sheet once the machine is generating revenue. Ask what happens when something goes wrong, whether remote diagnostics are available, who provides support, and how quickly problems can be identified.
The purchase price is only part of the investment. Electricity or nitrogen, staff time, servicing, downtime, and maintenance all affect your real cost per session.
Think about what happens if cryotherapy succeeds at your facility. Can the system handle back-to-back demand? Does adding more clients require more staff? Will the chamber become a bottleneck? The system that works at ten sessions per week may not be the right one at fifty sessions per day.
Those questions tell you far more about the machine you are buying than a single negative temperature.
You are not buying a temperature
For a gym, spa, med spa, recovery center, or wellness facility, the goal is not to own the chamber with the biggest number on its brochure.
You need a system that works inside a real operation.
It needs to deliver an experience clients want to repeat.
It needs to fit your space and electrical requirements.
It needs enough capacity for your expected volume.
It should not tie up your team unnecessarily.
And the economics need to make sense once the chamber is actually running.
Temperature matters.
It just should not be the only thing deciding which cryotherapy chamber you buy.
Frequently asked questions
Whole-body cryotherapy systems are marketed across a very wide temperature range, with some manufacturer-stated temperatures below -150°C. However, the stated temperature may not represent the exact temperature of the air surrounding the user. Different systems and manufacturers measure and describe temperature differently.
No. Air temperature influences cooling, but airflow, exposed surface, session duration, chamber design, and the individual user also affect the thermal response. Published research has demonstrated substantial skin cooling in forced-convection systems operating at considerably less extreme air temperatures than some cryotherapy systems advertise.
Artica uses perceived-temperature ratings to communicate the relative intensity of the cooling experience. The current Artica comparison lists Element at -90°F, Vortex at -100°F, and Ethos at -185°F. These should not be read as direct ambient-air temperature measurements.
Start with cooling performance, client experience, automation, service, operating cost, and capacity. Then match the machine to your expected session volume, facility type, available space, and customer profile. That is more useful than simply choosing the chamber with the lowest advertised temperature.
