The Inflammation Question
An evidence brief on whole-body cryotherapy — for practitioners, founders, and clients.
Three decades of peer-reviewed research now point to a single biological mechanism behind accelerated skin ageing, age-related decline, and the most difficult symptoms of menopause. The mechanism has a name. So does the intervention that addresses it.

Chronic, low-grade inflammation is no longer the boring footnote of internal medicine. It is the line connecting an aesthetic clinic's most frustrating post-procedure outcomes, an ageing patient's mounting joint stiffness, and a fifty-year-old woman's third hot flush before lunch. The biology is one story. The therapeutic response — increasingly — is also one story.
In May 2025, a meta-analysis in Nature Scientific Reports pooled the data from eleven randomised controlled trials and found that whole-body cryotherapy (WBC) produced statistically significant reductions in the three most consequential pro-inflammatory cytokines in human biology: interleukin-6 (IL-6), tumour necrosis factor alpha (TNF-α), and C-reactive protein (CRP). A 2024 cohort study published in JMIR by researchers affiliated with the Stanford Lifestyle Medicine programme then demonstrated that the effect, once established, can persist for up to nine months.
What follows is the working brief for three audiences who are asking variants of the same question — and arriving at the same answer.
I. For the Spa, Beauty & Cosmetic Industry
Why your treatments underperform on inflamed skin.
Every laser practitioner has experienced it. The client with an apparently routine baseline who responds to a standard IPL or fractional protocol with disproportionate erythema, prolonged oedema, and recovery times that stretch from days into weeks. The treatment was correct. The cellular environment was not.
Inflammatory cytokines — the same IL-6, TNF-α, and CRP that the Nature meta-analysis identified as cryotherapy's primary targets — are also the molecules that degrade collagen and elastin, the two proteins your treatments work to preserve and stimulate. Elevated systemic CRP correlates with reduced skin clarity, compromised barrier function, and reactive flushing. The pro-inflammatory baseline is the reason an objectively well-executed treatment can produce a subjectively disappointing result.
The clinics integrating cryotherapy are not adding a new service. They are improving the cellular environment in which their existing services already work.

The Three-Minute Protocol
A WBC session is short: two to three minutes inside a chamber held between −110°C and −160°C. The body's response is not. The cold exposure triggers vasoconstriction followed by reactive vasodilation, an autonomic cascade that lowers systemic inflammatory cytokines and stimulates fibroblast activity — the cells responsible for collagen and elastin production.
The Stanford-affiliated cohort study found that six or more sessions per month was the threshold for measurable reductions in high-sensitivity CRP in otherwise healthy adults, with the effect sustained for up to nine months.Translated into clinic operations: six sessions per month is the natural shape of a recurring package. The science prescribes the commercial model.

Where It Fits
In a Beauty, Laser, or Aesthetic clinic, the integration points are direct.
Pre-treatment. A session 24–48 hours before laser, IPL, or microneedling lowers the inflammatory baseline and reduces the disproportionate response some clients experience.
Post-treatment. A session afterwards calms the visible inflammation that lengthens downtime.
Recurring care. A 6-pack or 12-pack package aligns with the published clinical threshold for sustained benefit.
Premium tier. An evidence-based service that no nitrogen-cryosauna competitor can match, because cryosaunas are partial-body and do not produce equivalent systemic effects.
II. For the Ageing Population
Inflammaging — the silent biology of decline.
Geriatric medicine has a precise term for the chronic, low-grade inflammation that accumulates with age: inflammaging. Coined in the early 2000s and now widely used in peer-reviewed gerontology, the term describes the slow elevation of pro-inflammatory cytokines that drives, or at least co-travels with, almost every age-related disease state we treat: cardiovascular disease, type 2 diabetes, sarcopenia, osteoporosis, cognitive decline, and the frailty syndrome that lies at the centre of geriatric decline.
A 2017 review published in Frontiers in Physiology — the gold-standard literature review on WBC for older adults — described inflammaging as the unifying biology of age-related decline and identified WBC as one of the few non-pharmacological modalities that directly intervenes on the underlying cytokine profile.
A 2021 study of 84 older adults with subjective cognitive impairment is one of the most interesting recent contributions. Over nine weeks, three cohorts were studied: standard care, computerised cognitive training plus psychoeducation, and the same cognitive training combined with ten sessions of whole-body cryotherapy. The combination cohort — the WBC group — showed the most encouraging response.
Inflammaging is the working biology of getting older. The question is not whether to address it, but how.
— After Lombardi, Ziemann & Banfi (2017)
The physiological argument for cryotherapy in older adults is straightforward and well documented. The cold exposure triggers a measurable anti-inflammatory cascade, an antioxidant response (elevated glutathione peroxidase and superoxide dismutase activity), and short-term improvements in joint mobility, sleep architecture, and pain perception that older patients consistently report. A 2017 study published in Aging Clinical and Experimental Research additionally noted improvements in cardiac autonomic function in older subjects following a course of WBC sessions.
What WBC does not do, in older adults, is replace musculoskeletal exercise or pharmacological management where indicated. What it does do is intervene on the inflammatory substrate — the soil rather than the symptom — in a manner that the published evidence base now supports.
III. For Women Navigating Menopause
The cold answer to a hot question.
The clinical picture of perimenopause and menopause is dominated by symptoms that share a single autonomic mechanism. Hot flushes and night sweats are the body's response to a sudden, inappropriate activation of heat-loss pathways. Declining oestrogen destabilises the hypothalamus — the brain's thermoregulatory centre — so that small fluctuations in core body temperature trigger an exaggerated vasodilatory response. The result is the surge of heat, the sweat, the disrupted sleep, the mood disturbance.
In 2022, researchers at the University of Kent's School of Sport and Exercise Sciences, working with Dr Glen Davison and the Cryojuvenate clinic, ran one of the first dedicated trials of WBC in perimenopausal women. Nine women aged 40–65, each experiencing one or more moderate-to-severe hot flushes per day, completed six sessions of WBC at −85°C over a single week. Symptoms, sleep quality, and saliva biomarkers were tracked before, during, and after the intervention.
The Kent / Cryojuvenate findings:
Outcome, Result, Sleep, quality 40–50% self-reported improvement. Protocol 6 sessions in a one-week period. Chamber temperature−85°C, 3 to 5 minute exposures. Hot flush severity Consistent reductions over treatment week.
The participants reported a 40–50% improvement in sleep quality over the course of the protocol, and consistent reductions in hot flush severity. The proposed mechanism is consistent with what the rest of the literature already shows: cortisol reduction, autonomic nervous system rebalancing, and endorphin release. Cryotherapy doesn't restore oestrogen. It modulates the downstream autonomic chaos that follows oestrogen's decline.
A 2024 pilot reported in JMIR noted that WBC has also demonstrated CRP reduction specifically in postmenopausal women with type 2 diabetes — a population in which systemic inflammation contributes to the worst cardiovascular and metabolic outcomes. The implication: the menopausal benefit may not be limited to the most visible symptoms.
Forty to fifty per cent improvement in sleep quality, over one week of treatment, in women whose nights had been routinely broken for years. This is the kind of effect size that gets a clinician's attention.

What This Looks Like In Practice
For a day spa or beauty business serving women in their forties, fifties, and sixties — the demographic that drives the recurring-revenue line of nearly every wellness business in Australia — the menopausal use case is among the most commercially important applications of WBC. The published evidence remains early. The clinical signal is strong. The protocol is short (3–5 minutes per session) and the integration with an existing service menu is straightforward.
IV. The Accessibility Question
Why this is suddenly possible.
For most of the last twenty years, whole-body cryotherapy was something that happened in research clinics in Poland and elite athletic recovery rooms in the United States. The technology that delivered it — partial-body cryosaunas cooled by liquid nitrogen — cost between AUD $80,000 and $150,000, required ventilation infrastructure, oxygen monitoring, supplier dependencies on liquid-nitrogen tanks, and carried real workplace-safety risk. The science was clear. The economics were prohibitive for most clinics and spas.
That has changed. Electric whole-body cryotherapy chambers — cooled by industrial refrigeration rather than gas — now account for approximately half of all new cryotherapy installations globally. They draw 400 watts from a standard 10-amp plug, require no nitrogen tank, no supplier dependency, no ventilation works, and no monthly gas cost. They deliver true whole-body exposure — head included — which the published literature consistently shows produces a superior systemic effect compared to partial-body cryosauna exposure.
KRYO KUBE manufactures the first and only Australian made electric whole body cryotherapy chamber. The range begins at AUD $35,000.
