Whole-Body Cryotherapy in Multiple Sclerosis: Safety, Efficacy, and Guidelines

Introduction

Multiple sclerosis (MS) is a chronic inflammatory demyelinating disease of the central nervous system, with clinical subtypes including relapsing-remitting MS (RRMS), secondary progressive MS (SPMS), and primary progressive MS (PPMS) mdpi.com. MS produces a wide range of symptoms – from spasticity and pain to fatigue, heat sensitivity, and mood disturbances – that impact function and quality of life mdpi.commdpi.com. Whole-body cryotherapy (WBC) involves brief exposures (2–3 minutes) to extremely cold air (typically −110°C to −160°C) in a cryochamber, with participants wearing minimal protective clothing (gloves, socks, headband, mask) to prevent cold injury mcpress.mayoclinic.org. This therapy has gained attention as an adjunctive treatment in MS rehabilitation, aiming to mitigate symptoms such as spasticity, fatigue, pain, and inflammation when conventional treatments are insufficient mdpi.com. Below, we provide a detailed review of the mechanisms by which WBC may affect MS pathophysiology, summarize clinical research on its benefits and risks, discuss safety and contraindications, and outline current usage protocols and recommendations for practice.

Physiological Mechanisms of WBC in MS

Thermal Effects on Nerve Conduction: Many MS patients experience heat sensitivity (Uhthoff’s phenomenon), where elevated body temperature worsens nerve conduction in demyelinated fibers. Cooling, conversely, can restore conduction and improve symptoms. For example, external cooling (cooling suits) has been shown to reduce conduction block in demyelinated nerves, partly by reducing nitric oxide (NO) levels that impair nerve signaling mdpi.com. (NO is implicated in MS-related neuroaxonal damage and conduction fatigue; lowering NO via cooling may thus transiently improve neural function mdpi.com.) Whole-body cryotherapy rapidly lowers skin and possibly core temperature, which may similarly improve neuromuscular transmission and alleviate symptoms like motor fatigue or tremor in heat-sensitive patients. However, studies specifically measuring NO in MS found that WBC did not significantly change systemic NO levels (only a non-significant downward trend) mdpi.com, suggesting that while cooling helps nerve function, its mechanism may involve more than just NO modulation.

Anti-Inflammatory and Immune Modulation: MS is characterized by chronic CNS inflammation and an immune-mediated attack on myelin mdpi.com. Cryotherapy is thought to blunt inflammatory processes; indeed, exposure to extreme cold triggers systemic anti-inflammatory responses in other conditions (e.g. reduced levels of certain cytokines in rheumatoid arthritis). In the context of MS and other autoimmune diseases, preliminary evidence suggests that cold exposure can lower pro-inflammatory cytokines msfocus.org. This cytokine reduction could translate to less immune-mediated tissue damage and symptomatic relief (e.g., less swelling or pain in affected tissues). Additionally, cold stress activates the sympathetic nervous system, causing release of adrenaline and noradrenaline, which can modulate immune cell activity and cytokine production. WBC may also provoke a short-term increase in cortisol (an anti-inflammatory hormone), though specific data in MS is limited. The vasoconstriction during cold exposure followed by reactive vasodilation after exit may help flush out inflammatory mediators and improve microcirculation in muscles and joints.

Oxidative Stress and Antioxidant Defense: Oxidative stress plays a role in MS pathogenesis by contributing to demyelination and neurodegeneration mdpi.com. MS patients have been found to have impaired antioxidant defenses and increased markers of oxidative damage. WBC appears to enhance the body’s antioxidant capacity. Studies have shown significant increases in antioxidant enzymes and molecules after a series of WBC sessions in MS patients. For example, one trial noted a rise in superoxide dismutase (SOD) activity and a trend toward increased glutathione activity post-WBC mdpi.com. Similarly, Miller et al. reported that 10 sessions of WBC (−120° to −110 °C, 2–3 minutes) increased total antioxidant status (TAS) in MS patients mdpi.com. WBC also elevated uric acid levels mdpi.com, an important endogenous antioxidant that is often low in MS patients and has been hypothesized to be neuroprotective. Notably, in a study of SPMS patients, uric acid levels increased immediately after a WBC cycle and remained higher at 1 and 3 months post-treatment, correlating with sustained clinical improvements mdpi.com. These findings suggest WBC may reduce oxidative stress in MS, potentially slowing damage to neurons and supporting repair mechanisms.

Neuroendocrine and Analgesic Effects: Extreme cold exposure induces the release of endorphins and catecholamines as part of the stress response. Endorphins are natural painkillers and mood modulators. This is consistent with reports that cryotherapy can yield immediate pain relief and mood elevation in MS patients, likely through endorphin release msfocus.org. Patients often report feeling an energy boost and reduction in pain after sessions – one MS patient described that post-cryotherapy her pain was “virtually gone” and she experienced improved mental clarity and energy msfocus.orgmsfocus.org. The sympathetic surge from WBC (often evidenced by a temporary rise in blood pressure and heart rate) also triggers analgesic pathways, which can reduce neuropathic pain and spasticity. Cold exposure decreases nerve conduction velocity and muscle spindle activity, which can attenuate spastic reflexes and muscle tone. Thus, WBC may transiently reduce spasticity by dampening stretch reflexes and reducing muscle spasm, contributing to easier mobility in spastic paresis. In summary, through a combination of biochemical and neurophysiological pathways – reduced inflammation, improved antioxidant status, stress-hormone release, and direct neuromuscular effects – whole-body cryotherapy could plausibly counteract several mechanisms of MS-related symptoms.

Clinical Benefits and Efficacy Evidence

Effects on Mobility and Fatigue: A number of peer-reviewed studies have explored WBC as an adjunct therapy in MS, generally finding improvements in functional outcomes. In a clinical trial series from Poland, WBC was associated with better scores on mobility and disability scales. For example, Pawik et al. reported a significant improvement in the Rivermead Mobility Index (a gait and mobility measure) after a 2-week course of daily WBC sessions mdpi.com. Miller et al. similarly found improved functional status on the MS Impact Scale (MSIS-29 physical subscore) and a reduction in fatigue severity (measured by the Fatigue Severity Scale) in patients receiving WBC alongside rehab exercises mdpi.com. Another study noted increases in muscle strength (handgrip dynamometry) and better gait performance after 10 sessions of WBC, with treated patients also reporting less subjective fatigue mdpi.com. These findings align with patient anecdotes that cryotherapy sessions can boost stamina and reduce the sense of exhaustion that plagues ~80% of people with MS. Importantly, the benefits on fatigue and mobility were most pronounced when WBC was combined with active physiotherapy. In a comparative trial, an exercise-only group and an exercise + WBC group were evaluated: while exercise alone helped, the combination led to the greatest gains in walking capacity and functional mobility advances.umw.edu.pl. This suggests cryotherapy complements rehabilitation by enabling patients to participate more effectively in exercises (perhaps by temporarily easing pain and spasticity). Some patients with progressive MS have also shown notable responses; for instance, in one study of SPMS patients, a cycle of 20 WBC sessions not only yielded immediate improvement on the Expanded Disability Status Scale (EDSS) but this improvement was still evident at 1 and 3 months post-therapy mdpi.com. Such sustained effects hint that WBC might induce neuroplastic changes or prolonged anti-inflammatory effects, although more research is needed to confirm long-term benefits.

Pain Relief and Sleep Quality: Chronic pain (neuropathic pain, musculoskeletal pain, painful spasms) is a significant issue in MS, as is poor sleep quality often secondary to pain, nocturnal spasms, or bladder dysfunction. WBC has demonstrated analgesic effects in MS populations. Patients frequently report immediate reduction in pain intensity after exiting the cryochamber – a relief that can last for hours to days. In a 2022 controlled study, WBC was found to significantly reduce pain scores on a Numeric Rating Scale (NRS) in MS patients compared to baseline mdpi.com. Notably, this study also evaluated sleep outcomes: after 10 sessions of WBC, participants had improved sleep quality (measured by the Pittsburgh Sleep Quality Index, PSQI) and this benefit became even more evident at follow-up a few weeks later mdpi.com. The authors concluded that WBC shows potential for managing MS symptoms, “particularly pain and sleep quality,” with some effects emerging after a delay and no worsening of any measured parameters mdpi.com. These improvements in sleep could be secondary to pain reduction (allowing more comfort at night) and possibly to reductions in nocturnal spasticity. Moreover, cryotherapy’s activation of endorphin release likely contributes to pain relief and a sense of well-being that facilitates better sleep. It is noteworthy that none of the studies reported a deterioration in symptoms or neurologic status from WBC mdpi.com – e.g., there were no MS relapses or pain rebounds attributed to the cold therapy – indicating that, for pain control, WBC is at least neutral or helpful in the short term. Additionally, outside of formal studies, people with MS have anecdotally noted that regular cryotherapy sessions help decrease daily aches and even reduce the frequency of muscle spasms, though individual responses vary. Better pain control and sleep can have cascading positive effects on daytime fatigue and overall quality of life, reinforcing the value of symptom-targeted treatments like WBC in a comprehensive MS management plan.

Mood and Quality of Life: Beyond physical symptoms, MS often affects psychological well-being – depression and anxiety are common comorbidities, and chronic illness can diminish overall quality of life (QoL). Interestingly, whole-body cryotherapy may impart psychologic and QoL benefits. Cold exposure is known to trigger a surge of norepinephrine in the brain and release of endorphins, which can elevate mood. In MS studies, patients undergoing WBC have shown reduced anxiety and depression scores. For example, one trial observed a significant drop in the Hospital Anxiety and Depression Scale (HADS) anxiety subscore in an MS group receiving WBC plus exercise, as well as a reduction in depressive symptoms (HADS-D) after a series of WBC sessions mdpi.com. Similarly, improvements in the Psychological General Well-Being Index have been reported, indicating an overall boost in mental health and coping ability mdpi.com. Miller et al. noted an improvement on the MSIS-29 psychological impact scale after WBC, suggesting patients felt better emotionally and socially mdpi.com. These effects could be due to biochemical changes (endorphins, dopamine, etc.) or simply the result of feeling more physically capable and in control of symptoms, thereby reducing stress. Sleep improvements from WBC, as mentioned, also likely contribute to better mood and cognitive function during the day. Additionally, some patients describe a cryotherapy session as “recharging” or giving a mental refresh – possibly related to the concept of cold-induced stress resilience. No adverse psychological effects have been noted; on the contrary, some progressive MS patients with significant disability have reported that WBC sessions gave them a sense of well-being and hope, which can positively influence rehabilitation engagement. While these findings are encouraging, it should be stressed that WBC is not a primary treatment for MS depression or cognitive impairment, but it may be a useful complementary strategy to improve mental outlook and energy when used as part of a multidisciplinary approach. Larger studies are needed to confirm the mood-enhancing properties of cryotherapy, but early results align with observations of improved sleep, reduced fatigue, and better QoL scores in WBC-treated individuals mdpi.com.

Disease Activity and Progression: A common question is whether WBC can modify the course of MS or if it is purely symptomatic. There is no evidence that cryotherapy can alter the underlying disease progression or reduce relapses in RRMS – it is not a disease-modifying therapy. However, by potentially reducing inflammatory stress and improving antioxidant capacity, one could hypothesize minor impacts on disease biology. For example, the sustained increase in uric acid and trend towards lower oxidative stress markers post-WBC might conceivably have neuroprotective effects over time mdpi.com. Some patients with SPMS in Miller’s study showed stability or slight improvement in their EDSS disability scores months after WBC mdpi.com, which is intriguing given SPMS is usually relentlessly progressive; however, this could be due to prolonged symptomatic relief rather than true slowing of disease. No peer-reviewed trial has demonstrated fewer new MRI lesions or a change in relapse rate with WBC. Thus, WBC should be viewed as an adjunct for symptom management, not as a replacement for immunomodulatory drugs. Its benefits (pain control, better mobility, etc.) may indirectly improve a patient’s activity levels and overall health, which is certainly positive but not a cure for the disease. All major improvements reported with WBC in MS have been in symptom scales and functional tests rather than direct measures of demyelination or CNS lesion load. In summary, WBC’s clinical efficacy lies in symptomatic relief – improving day-to-day functioning and comfort for people with MS across various subtypes – which in turn can enhance participation in therapy and daily activities.

Safety and Contraindications

Overall, whole-body cryotherapy is well-tolerated by most individuals with MS when proper protocols are followed. Notably, a recent scoping review of WBC in MS reported no adverse effects in any of the included studies across more than 1000 sessions, indicating an excellent safety profile in controlled clinical settings mdpi.com. Patients generally did not experience disease worsening or serious complications from the cold exposure. However, it is critical to distinguish between controlled therapeutic use and unsupervised use; WBC does impose physiological stress, and certain patients are at risk for harm if not screened appropriately.

Acute Physiological Reactions: During a cryotherapy session, the extreme cold causes a “fight or flight” response. Acute exposure to cold air triggers peripheral vasoconstriction and a transient rise in blood pressure and heart rate mcpress.mayoclinic.orgmcpress.mayoclinic.org. This pressor effect (cold-induced hypertension) is usually well-compensated in healthy individuals, but in those with severe cardiac or vascular disease it could precipitate issues (e.g. arrhythmia, angina). Most MS patients do not have significant cardiovascular comorbidity at young ages, but older patients or those with long-standing disease might. Cold can also induce shivering and a stress hormone surge. These responses are generally transient and resolve upon rewarming. Minor side effects reported anecdotally or in broader WBC literature include: cold-induced skin irritation (pseudourticaria or mild frostnip on exposed skin), headache or lightheadedness, transient numbness or tingling, and occasionally reactive hypertension immediately post-session frontiersin.org. Two very rare but documented adverse events in the literature are a case of cold-induced panniculitis (inflammation of subcutaneous fat) and a case of transient global amnesia, both of which resolved and were thought to be idiosyncratic responses frontiersin.org. There is also a report of intracerebral hemorrhage in an individual with untreated hypertension and migraine who underwent WBC – this patient likely should not have been cleared for treatment, underscoring the importance of observing contraindications frontiersin.org. Overall, decades of use in Europe have yielded only a handful of serious adverse events, implying that WBC, when applied judiciously, has a low risk profile (mostly minor and transient effects) frontiersin.orgfrontiersin.org. Underreporting is possible, but the consensus is that WBC is safe provided proper screening and precautions are in place frontiersin.org.

Contraindications: Before prescribing WBC, patients must undergo medical screening. Many contraindications relate to conditions that could be exacerbated by extreme cold or by the physiological stress of cryotherapy. Key contraindications include:

• Unstable Cardiac or Vascular Disease: Whole-body cryotherapy is contraindicated in individuals with significant cardiovascular issues such as ischemic heart disease, recent myocardial infarction, uncontrolled hypertension, advanced heart failure, severe arrhythmias, or implanted cardiac devices (e.g. pacemaker) frontiersin.org. Active vasculitis or history of thrombosis/embolism in the last 6 months are also exclusionary frontiersin.org. The cold-induced blood pressure spike and vasoconstriction could pose risks of angina, stroke, or arrhythmia in these patients.
• Autonomic Dysfunction and Neurologic Disorders: MS itself can cause some autonomic dysfunction, but severe neurovegetative dysautonomia or peripheral neuropathies affecting cardiovascular reflexes are contraindications frontiersin.org. Patients with these issues may not adjust heart rate/BP properly in response to cold, risking syncope or blood pressure instability. Likewise, a history of epilepsy (uncontrolled seizures) or very recent stroke (<12 months) would generally preclude WBC frontiersin.org. Cognitive inability to understand or follow safety instructions (due to advanced dementia or psychiatric conditions) is also a contraindication, since the patient must communicate and adhere to protocols in the chamber frontiersin.org.
• Cold Hypersensitivity and Raynaud’s Phenomenon: Any condition where cold exposure triggers pathology is an absolute contraindication. This includes cold-induced urticaria, cryoglobulinemia, cold agglutinin disease, paroxysmal cold hemoglobinuria, or severe Raynaud’s disease frontiersin.org. In such cases, exposure to −110°C could cause serious reactions like hemolysis, extreme blood viscosity changes, or tissue ischemia. Patients should be specifically asked about prior cold-intolerance reactions.
• Severe Respiratory or Other Systemic Illness: People with advanced organ insufficiency should avoid WBC. For example, severe chronic obstructive pulmonary disease (COPD stage III–IV) or uncontrolled asthma is a contraindication, as the cold air could induce bronchospasm and these patients may not tolerate even brief hypoxia if it occurs frontiersin.org. Likewise, those with Stage 4 renal failure or active tuberculosis infection should not undergo WBC frontiersin.org. Uncontrolled metabolic/endocrine disorders like untreated hypothyroidism, adrenal insufficiency, or poorly controlled diabetes (especially type 1 or type 2 with vascular complications) are contraindicated due to potential arrhythmias or neuropathic impairments that increase risk frontiersin.org. If diabetes is well-controlled and without severe neuropathy, WBC might be allowable with caution, but each case must be judged individually.
• Acute Medical Conditions and Other Factors: Pregnancy is listed as a contraindication (precautionary) – the circulatory changes and stress hormones from WBC are not recommended during pregnancy frontiersin.org. Any acute infection or fever should also exclude a patient until resolved frontiersin.org, since the body’s resources should not be additionally stressed. Similarly, patients with severe anemia or low platelet counts should avoid WBC until corrected frontiersin.org, as should those on certain medications (e.g. spasmogenic or cardiotoxic drugs that might interact poorly with cold-induced sympathetic surge frontiersin.org). Claustrophobia is a practical contraindication – those who cannot tolerate the enclosed chamber (which is akin to standing in a closet-sized space) should not be forced, although some modern chambers are more spacious or open-topped. Finally, advanced age (over ~80 years) is cautioned against, as the elderly have reduced thermal regulation and may not mount an adequate physiological response to extreme cold frontiersin.orgfrontiersin.org. Each WBC facility typically uses a medical questionnaire to screen for all these contraindications and will measure blood pressure and pulse before each session to ensure safety frontiersin.org.

In summary, patient selection is crucial. For a relatively young MS patient without significant cardiorespiratory disease and no cold intolerance, WBC is generally very safe. However, comorbid conditions must be reviewed. When in doubt, consultation with a cardiologist or other specialist is advised before clearance. The motto “first, do no harm” is applicable – if any serious condition is present, it is safer to avoid WBC or seek an alternative like local cooling of parts of the body. Importantly, even in healthy patients, sessions must be supervised by trained personnel, with adherence to time limits (to prevent frostbite or hypothermia) and monitoring of the patient’s status (some facilities check skin temperature or oxygen saturation). With these precautions, WBC has an excellent safety record in MS rehabilitation settings frontiersin.org.

Treatment Protocols and Optimal Use Parameters

Typical WBC Regimen: There is no single standardized protocol for WBC in MS – protocols in studies have varied in temperature, frequency, and duration. Generally, therapy is delivered as a course of daily sessions over a few weeks. Common regimens involve 10 to 20 WBC sessions, administered 5 days per week (e.g. two weeks of weekday sessions), though some programs extend to 30 sessions mdpi.com. Each session consists of a short exposure (usually 2–3 minutes) in a chamber cooled between approximately −110°C and −140°C (some facilities go as low as −160°C) mdpi.com. For instance, a typical protocol used in research: patients underwent 3 minutes at −120°C once daily for 20 consecutive days mdpi.com. Another trial used 10 sessions of 2–3 minutes at −130°C over two weeks advances.umw.edu.pl. The difference between −110°C and −140°C in practice may not be large in physiological effect – both are extreme cold far below freezing, and both will induce the desired response (skin temperature drop, etc.) within a 2–3 minute window. Thus, a chamber operating at −84°C (slightly warmer than typical) would still produce significant cold stress if exposure time is sufficient, though many cryotherapy centers strive for ≤−110°C for maximal effect mdpi.com. In all cases, sessions should not exceed 3 minutes to avoid hypothermia or frostbite. First-time users might start with shorter exposure (e.g. 1.5–2 minutes) to gauge tolerance, then increase to the full duration on subsequent visits.

Procedural Considerations: Before entering, patients must be dry (no sweat or lotion on skin) and wear the protective gear on the most vulnerable body parts: hands (gloves), feet (dry socks and clogs), ears/head (headband or cap), mouth/nose (mask or scarf) mcpress.mayoclinic.org. Jewelry or glasses are removed. Usually, the patient steps into a preparatory antechamber around −60°C for 30 seconds to acclimate, then moves into the main chamber at −110°C or below. They remain standing (or slowly walking in place) and are monitored through a window or camera. Communication via intercom is maintained, and music or instructions may be given to help with tolerance. After the timed exposure, the patient exits and immediately begins a re-warming phase, which often involves light exercise. In MS rehabilitation programs, it’s standard to follow WBC with 15–30 minutes of physiotherapy or exercise while the body rewarms mdpi.com. This might include stretching, strengthening exercises, or gait training. The rationale is that WBC may temporarily increase pain threshold and reduce spasticity, allowing patients to exercise more effectively with less discomfort mdpi.com. Exercise also promotes circulation, which helps rewarm muscles and may extend the benefit of the cryostimulation.

Optimal Frequency and Duration: Current evidence does not definitively dictate an “optimal” number of sessions; however, consistency and repetition appear important. Benefits on fatigue, mood, and mobility have typically been observed after a full course (e.g. 10+ sessions), rather than after a single treatment, though pain relief can be noted acutely even from one session. In research by Lubkowska and others, a single WBC session produced some biochemical changes but clinical improvements (in strength or function) were only modest until multiple sessions were accumulated mdpi.com. Most studies showing significant functional gains used at least 10 sessions in a 2–4 week period mdpi.com. Some outcomes (like improved sleep or quality of life measures) were more evident at a follow-up (weeks after completing therapy), suggesting a cumulative or delayed effect mdpi.com. For long-term management, patients might undergo repeated courses of WBC during the year. For example, anecdotally, some MS centers offer cryotherapy cycles seasonally (e.g. 2–3 courses per year) or prior to expected high-heat seasons to mitigate heat sensitivity. In practice, outside of trials, athletes and patients sometimes use WBC on an ongoing basis (e.g. 1–3 sessions per week) to maintain benefits; however, for MS, the resource-intensive nature of daily chamber sessions means it is usually done in focused bursts as part of a rehab program.

Monitoring and Adjustments: During the WBC course, outcomes should be monitored. Patients often keep a symptom diary (recording fatigue levels, pain scores, sleep quality, etc.) to track changes throughout the treatment. If no improvement is seen after a reasonable trial (say 5–10 sessions), or if any adverse reactions occur, continuing WBC may be re-evaluated. Conversely, if a patient responds very well, clinicians may consider extending the number of sessions (some studies went up to 20 or 30 sessions safely mdpi.com). There does not appear to be a hard upper limit in a supervised setting, as long as skin integrity and patient tolerance are maintained, but diminishing returns after a certain point are possible. Between sessions, patients are advised to stay well-hydrated and not to take hot showers or baths immediately (to let the body re-acclimate gradually). Importantly, WBC should be integrated with other therapies: for example, continuing disease-modifying medications (DMTs), using physiotherapy, and employing home-based cooling strategies on hot days (like cooling vests or air conditioning), since WBC is not a stand-alone treatment.

Recommendations and Expert Consensus

Official Guidelines: At present, no major neurology or MS-specific professional society has issued formal guidelines endorsing whole-body cryotherapy as a standard treatment. The American Academy of Neurology (AAN) and the European Committee for Treatment and Research in MS (ECTRIMS) have not included WBC in their MS management protocols, likely due to the relatively small number of trials and lack of large-scale randomized controlled studies. MS treatment guidelines focus on FDA-approved medications and well-established rehab strategies; newer or alternative interventions like WBC are usually described as investigational. For example, the U.K. NICE guidelines on MS management emphasize conventional symptom management (pharmacologic and physiotherapy) and do not mention cryostimulation. That said, cooling techniques in general are recognized in the MS community: both the National MS Society and MS patient organizations encourage heat-sensitive patients to use cooling vests, cool baths, or air conditioning to prevent symptom flares emsp.org. In fact, multiple studies have shown that cooling garments can improve fatigue and walking endurance in MS by counteracting heat intolerance nationalmssociety.org. This acknowledgement lends indirect support to the idea of therapeutic cooling. WBC can be viewed as an intensive form of cooling, and its emerging evidence base has started to draw interest from rehabilitation specialists.

Physiotherapy and Rehabilitation Perspectives: Many physiotherapists and rehabilitation physicians are aware of WBC as a modality and may recommend it on a case-by-case basis. In countries like Poland, WBC has been integrated into some MS rehab programs for years (hence the preponderance of Polish studies on the topic). A 2019 paper by Pawik et al. concluded that “the introduction of WBC into the standard physiotherapy protocol for patients with MS is fully justified.” advances.umw.edu.pl, after their trial showed enhanced psychological well-being and functional status in the WBC+exercise group. Similarly, experts have noted that WBC can complement conventional therapy by enabling better participation in exercise and providing symptomatic relief mdpi.com. However, these are recommendations from researchers rather than official bodies. The International Institute of Refrigeration’s WBC Working Group (a panel of cryotherapy experts across disciplines) recently published a position paper focusing on safety and contraindications, aiming to standardize practice and ensure WBC is used responsibly frontiersin.org. They reiterate that medical screening and supervision are mandatory for WBC to be considered safe frontiersin.org. Their stance is that when properly applied, WBC is a safe rehabilitative procedure for various conditions including MS, but practitioners must stay within evidence-based guidelines for exposure and exclude high-risk patients.

Patient Education and Informed Decision: Clinicians should counsel MS patients that while WBC has shown promise in alleviating symptoms like pain, fatigue, and mood disturbances, it is not a cure and individual responses vary. Patients who are curious about trying WBC should be advised to do so in a medical or accredited setting (many MS clinics or sports medicine centers offer cryotherapy) rather than a spa without medical oversight. It is also important to set realistic expectations: some patients feel dramatic improvements, while others may feel only mild changes or none at all. As the Mayo Clinic’s holistic health experts note, research into cryotherapy is still in its infancy and more studies are needed to conclusively prove its long-term efficacy mcpress.mayoclinic.orgmcpress.mayoclinic.org. They advise that if one chooses to pursue it, they should discuss it with their healthcare team and use it as a complementary approach, not as a replacement for proven therapies mcpress.mayoclinic.org. The “jury is still out” on some of the broader health claims mcpress.mayoclinic.org, but within the MS realm, current evidence does consistently point to short-term symptom relief and no major safety issues.

In practice, if an MS patient (with no contraindications) is struggling with symptoms like spasticity or fatigue that limit their therapy participation, a neurologist or physiotherapist might suggest a trial of WBC to see if it improves their tolerance for activity. Conversely, for a patient who is very frail or has significant comorbidities, clinicians would steer away from WBC due to safety concerns. As research evolves, we may see more formal recommendations. For instance, if larger RCTs confirm that cryotherapy significantly reduces fatigue or improves QoL in MS, professional guidelines could incorporate it as an optional adjunct for symptom management, similar to how body cooling is recommended for heat-aggravated symptoms emsp.org.

Conclusion

Whole-body cryotherapy has emerged as a novel adjunctive therapy in the management of multiple sclerosis, targeting the symptomatic burdens of the disease. Physiologically, extreme cold exposure can counteract some of MS’s pathophysiological processes – reducing inflammation, oxidative stress, and conduction blocks – thereby offering relief for symptoms like pain, fatigue, spasticity, and depression. Clinical studies (albeit mostly small-scale) have documented improvements in functional mobility, reduction in fatigue scores, less pain and spasm, better sleep, and improved well-being in MS patients undergoing WBC mdpi.commdpi.com. Importantly, these benefits have been achieved without significant adverse effects in the short term mdpi.com. Whole-body cryostimulation thus appears to be a safe complement to standard MS treatments, particularly for patients in whom symptoms remain difficult to manage with medications alone.

Nevertheless, cryotherapy is a potent intervention and must be applied with caution. Strict adherence to contraindication screening and supervised protocols is mandatory to ensure safety frontiersin.org. MS patients with cardiovascular, autonomic, or severe systemic issues are not suitable candidates for WBC frontiersin.orgfrontiersin.org. For appropriate candidates, a typical regimen of ~10–20 daily sessions at ~−120°C, combined with rehabilitative exercise, can be considered in a specialized clinic setting mdpi.com.

From a physiotherapy perspective, WBC can be thought of as an adjunct modality – similar to hydrotherapy or therapeutic cooling – that may enhance the overall rehabilitation outcome when used judiciously. Neurological and rehabilitation associations have yet to issue formal guidelines on WBC, reflecting the need for more robust evidence. Ongoing research and clinical experience will better define optimal protocols, duration of benefits, and any long-term effects on disease course. Until then, practitioners should rely on available evidence and expert consensus: incorporate WBC on a case-by-case basis as part of a multimodal MS management plan, always prioritizing patient safety and informed consent. In summary, whole-body cryotherapy offers a promising avenue to alleviate MS symptoms – helping to “cool down” the inflammatory and neurodegenerative processes in a figurative and literal sense – but it should complement, not replace, established therapies. With further studies, WBC may earn a more central role in comprehensive MS care, especially for symptomatic relief and improving patients’ day-to-day function mdpi.commdpi.com.
