I spent six months driving to a cryo studio three times a week. Then I spent six months plunging at home. Now I want to save you the time and money I spent figuring out what I’m about to tell you.
Both cold plunge and cryotherapy work. Both have legitimate scientific backing. But they’re not interchangeable, and the popular discourse around them often misrepresents the key differences in how they affect the body.
This is my honest comparison after 12 months across both methods, with the research to back it up.
The Core Difference: How Each Method Cools Your Body
Cold plunge and cryotherapy are fundamentally different in how they reduce your body temperature — and that difference matters.
Cold water immersion (cold plunge): Water conducts heat away from your body approximately 25x more efficiently than air. When you submerge in 50°F water, your skin temperature drops rapidly, and with sufficient immersion time (2-5 minutes), your core body temperature drops by 2-3°F. Cold water creates hydrostatic pressure across your entire submerged body, which combined with vasoconstriction creates the characteristic “flushing” effect when you exit.
Cryotherapy (whole-body cryo): A cryotherapy chamber uses liquid nitrogen gas (or electric refrigeration in newer chambers) to lower the air temperature to -200°F to -300°F. Critically, air is a poor thermal conductor. Even at -250°F, air removes heat from your body significantly more slowly than 50°F water. Typical 3-minute cryo sessions drop your skin temperature substantially (by 40-50°F on the skin surface) but drop core body temperature by only 0.5-1°F.
Why this matters: Many of the recovery benefits attributed to cold exposure — reduced inflammation via sustained vasoconstriction, dopamine increase, metabolic adaptation — correlate more strongly with core temperature drop than skin temperature drop. Cold plunge achieves more core cooling in a single session.
The Science: What Research Shows
This is not a settled science area, but the research tilts in favor of cold water immersion for most outcomes:
Inflammation reduction: A 2019 systematic review in BJSM comparing cold water immersion to other recovery modalities found statistically significant reductions in DOMS (delayed onset muscle soreness) at 24 and 48 hours post-exercise. The same body of research on cryotherapy shows positive effects, but effect sizes are generally smaller in well-controlled studies.
Dopamine and mood: Andrew Huberman’s work (and the underlying research from Leppäluoto et al.) documents a 250-300% increase in dopamine following cold water immersion. The dopamine spike is significant, prolonged, and doesn’t habituate the way other dopamine triggers do. Similar data exists for cryo but the effect is less studied and appears smaller due to lower core temperature involvement.
Vasoconstriction duration: The hydrostatic pressure of water immersion combined with temperature creates sustained vasoconstriction that persists longer post-session than cryo-induced vasoconstriction. The “pumping” effect as you warm up post-plunge (blood rushing back to extremities, then pulling lymph and metabolic waste toward the body’s core filtration systems) is a key mechanism that cryotherapy partially replicates but less completely.
Important caveat: Much of the elite sports recovery research is on cold water immersion specifically. The NFL, NBA, and most professional training facilities with serious recovery budgets use cold plunge tanks, not cryo. That’s not definitive, but it’s a data point.
My 6-Month Cryo Experience
From months 1-6, I went to a cryo studio three times per week. Sessions were $60 each (one of the cheaper studios in my area — some charge $90+). The chamber I used was nitrogen-cooled, not electric.
What I noticed:
- Significant mood improvement for 4-6 hours post-session, particularly in terms of mental clarity and reduced anxiety
- Reduced DOMS from training — my leg days recovered faster
- Strong acute effect — the first three minutes in the chamber were exhilarating in a way that was genuinely enjoyable
What frustrated me:
- The claustrophobia factor: I’m not a claustrophobic person, but standing in a tube with just my head above the chamber, surrounded by nitrogen fog, created a low-grade anxiety that never fully went away. Several people I know tried cryo and stopped because of this. The enclosed space, the inability to exit instantly (the attendant controls the door from outside), and the cold-fog sensory environment are a real barrier for some people.
- Three sessions per week at $60 = $720/month. In six months I spent $4,320.
- The benefits wore off faster than I wanted. By evening of the session day, I felt normal. The “3-day carryover” some cryo advocates claim was not my experience.
My 6-Month Cold Plunge Experience
I started with a chest freezer conversion (more on this in my separate article comparing DIY to the Plunge All-In), then moved to a dedicated Plunge All-In.
What I noticed:
- Stronger and longer dopamine response than cryo. I feel genuinely different after a plunge — more alert, more focused, more positive — and that feeling lasts 4-6 hours consistently.
- Better sleep. I plunge in the evenings (around 5-6 PM) and my sleep quality as measured by my Oura Ring HRV improved measurably during the first three months.
- The post-plunge warmth — the 20-30 minutes after getting out when your vasodilation is in full effect — is one of the best physical feelings I’ve experienced in recovery. Nothing in cryo produced this.
- The cold water shock is more intense than cryo’s cold air shock. The first 30 seconds at 50°F water is objectively harder than standing in a cryo chamber.
The maintenance realities: Water treatment is ongoing work. I spend 10-15 minutes per week on water chemistry. I’ve dealt with a green water incident (two weeks without chlorine treatment during a travel period — do not do this). This is real maintenance that cryo sessions don’t require.
True Cost Analysis: 2 Years
Cryotherapy (3x/week):
| Item | Cost |
|---|---|
| Sessions at $60 (3x/week, 52 weeks/year) | $9,360/year |
| Travel time (if studio is not nearby) | Not included |
| Year 2 total | $9,360 |
| 2-year total | $18,720 |
Cold Plunge (home tub):
| Item | Cost |
|---|---|
| Plunge All-In | $4,990 |
| Annual electricity estimate | ~$360/year |
| Water treatment chemicals (chlorine, test strips) | ~$120/year |
| Water change (water cost) | ~$30/year |
| Filter replacement (annual) | ~$60/year |
| Year 1 total | ~$5,560 |
| Year 2 total | ~$570 |
| 2-year total | ~$6,130 |
The break-even point: If you plunge 3+ times per week, a Plunge All-In pays for itself in 7-8 months compared to a typical cryo studio pricing. At 6 months, you’re ahead on investment. The math is not close.
The Frequency Factor: Why It Changes Everything
The most important practical difference between these methods is access.
My cryo studio was 15 minutes from my house. After a hard training session, the decision to drive 15 minutes each way, pay $60, change into cryo clothing, wait for a chamber, do the session, and drive back — that full friction load means I’d skip sessions when I was tired or busy. My 3x/week goal became 2x/week in practice, then 1.5x/week during busy periods.
With a home cold plunge, I plunge 5-7 times per week. The friction is walking to my garage and sitting in a tub for 3 minutes. That’s it. Frequency matters enormously for cumulative health effects, and a home tub wins on frequency by a wide margin for most people.
Huberman and others who study cold exposure protocols consistently note that frequency and consistency produce more cumulative benefit than session intensity. A 3-minute cold plunge 5 days a week is likely more beneficial than a 3-minute cryo session 2 days a week.
Scenarios: When Cryo Still Makes Sense
Post-surgery or acute injury: For certain acute injury scenarios (swollen joint, post-op inflammation), a medical cryo protocol under clinical supervision may be more appropriate than home cold plunge. The chamber provides more controlled, uniform cold exposure for specific anatomical targets.
You don’t want the maintenance: Cold plunge tub ownership is like owning a hot tub — there’s ongoing chemistry work. If that friction sounds worse than a studio fee, cryo removes it.
Nitrogen nitrogen fog therapy specifically: Some practitioners claim that the nitrogen gas exposure itself has effects beyond temperature. This is not well-supported in the literature, but anecdotally some users swear by the “nitrogen feeling” that electric cryo doesn’t replicate. I don’t weight this heavily, but it’s a real preference some people have.
Trial before investing: If you’ve never done cold exposure, a few cryo sessions is a reasonable way to test your physiological and psychological response before committing $4,000+ to a home plunge setup.

The Verdict
Cold plunge wins for most people who are willing to manage the upfront cost and maintenance.
The combination of superior core temperature reduction, stronger and longer dopamine response, post-plunge vasodilation effect, better frequency accessibility, and dramatically lower 2-year cost makes cold water immersion the objectively better choice for the majority of regular users.
Cryotherapy is a legitimate recovery tool with real benefits. But it’s not as effective as cold plunge per session, it costs significantly more per session, and the frequency friction means most people use it less than they intend to.
My recommendation: If you’re committed to cold exposure as a regular practice, buy a plunge tub. If you want to test cold exposure before committing, try 6-10 cryo sessions to understand your response. If you then like how you feel, invest in a home setup and never look back.
