Psoriasis: A Guide to Whole-Body Cold Therapy

That Familiar Itch, That Hidden Skin

It is a warm, bright morning in the Allgäu, the kind of day that calls for short sleeves. But you find yourself reaching for a long-sleeved top once again. It is not about the temperature; it is about the silvery, raised patches on your elbows and the persistent, deep-seated itch that accompanies them. This daily negotiation with your skin is the reality for millions of people living with psoriasis. The condition dictates not just clothing choices, but can influence mood, sleep, and social confidence. While you follow your doctor's advice diligently, you may also be looking for complementary practices that can support your wellbeing and help you feel more comfortable in your own skin. It is in this context that some people are turning to practices like whole-body cold therapy, seeking a few minutes of relief in the profound cold.

Understanding Psoriasis: More Than Skin Deep

Before exploring any supportive measures, it is essential to have a clear understanding of what psoriasis is. It is not simply "dry skin", nor is it contagious. Psoriasis is a chronic autoimmune condition. This means your immune system, which is designed to fight off infections, becomes overactive and mistakenly attacks healthy skin cells.

Normally, your skin cells grow and are replaced over a period of about three to four weeks. In someone with psoriasis, this process is dramatically accelerated. The immune system sends out faulty signals that cause skin cells to be produced in a matter of days. Because the body cannot shed these excess cells quickly enough, they pile up on the surface of the skin, forming the characteristic thick, red, scaly patches or "plaques".

The precise cause remains complex, but it is understood to involve a combination of genetic predisposition and environmental triggers. You may have inherited genes that make you more susceptible, but the condition might only appear after being "switched on" by a trigger. Common triggers can include:

• Stress
• An injury to the skin (this is known as the Koebner phenomenon)
• Certain infections, such as strep throat
• Some medications
• Heavy alcohol consumption

Living with psoriasis often means identifying and managing your personal triggers, which is a key part of any long term management strategy alongside medical treatment.

Symptoms, Diagnosis and Medical Care

The most common form of the condition is plaque psoriasis, accounting for the majority of cases. You will likely recognise the symptoms: well-defined patches of red, inflamed skin covered with silvery-white scales. These plaques can appear anywhere on the body but are frequently found on the elbows, knees, scalp, and lower back. They can be intensely itchy, sore, or even feel like they are burning. For many, the itch, medically known as pruritus, is one of the most challenging symptoms to manage, often disrupting sleep and concentration.

Receiving a correct diagnosis is the first and most critical step. This should always be done by a qualified medical professional, usually a general practitioner or a dermatologist. They will typically diagnose psoriasis based on a physical examination of your skin, scalp, and nails. In some cases, a small skin sample, a biopsy, may be taken and examined under a microscope to rule out other skin conditions.

Once diagnosed, your doctor will discuss a treatment plan tailored to the severity and location of your psoriasis. Established medical treatments are the foundation of managing the condition and generally fall into three categories: 1. Topical treatments: These are creams, ointments, and lotions applied directly to the skin. They include corticosteroids, vitamin D analogues, and moisturisers to reduce inflammation and slow down cell production. 2. Phototherapy: This involves exposing the skin to specific types of ultraviolet (UV) light under medical supervision. This can be a very effective way to slow the rapid growth of skin cells. 3. Systemic treatments: For moderate to severe psoriasis, doctors may prescribe medications that work throughout the body. These can be pills or injections, including traditional immunosuppressants and newer "biologic" drugs that target specific parts of the immune system.

Any complementary approach, including whole-body cold therapy, should be considered an addition to, not a replacement for, the treatment plan prescribed by your doctor.

The Cold Chamber Experience at Kältekammer Memmingen

Understanding what to expect can help you feel prepared and relaxed for your first session. When you visit our studio in Memmingen, the focus is on your safety and comfort. You will be guided through every step of the process.

You will first change into suitable attire. For whole-body cold therapy, this means minimal clothing, such as shorts for men or shorts and a top for women, to allow for maximum skin exposure to the cold, dry air. To protect the body's extremities, which are more sensitive to the cold, you will be provided with gloves, socks, and footwear, as well as a mask to protect your airways and earmuffs.

The experience itself involves stepping into our state of the art cold chamber. You first enter a pre-chamber, set to a less extreme temperature, for a few seconds to help your body acclimatise. Then, you move into the main chamber, which is maintained at a constant -110 °C using an advanced vortex cooling system. This technology ensures the temperature is stable and the cold is felt uniformly over your body.

The cold you experience is a dry, crisp cold, not the damp, chilling cold you might associate with a winter's day. You will spend about three minutes in the main chamber, during which time you can move around gently. You are supervised at all times. After your session, you step out and your body immediately begins to warm up. Many people describe a pleasant tingling sensation as blood rushes back to the skin's surface, followed by a feeling of refreshment and invigoration.

How Whole-Body Cold Therapy May Offer Support

While it is crucial to state that whole-body cold therapy is not a cure for psoriasis, it is being explored for its potential to help manage some of the condition's most burdensome symptoms. The physiological response to the extreme cold may provide support in two key areas: inflammation and the sensation of itching.

Psoriasis is, at its core, an inflammatory disease. The application of intense cold is known to have a systemic anti-inflammatory effect. When your body is exposed to -110 °C, it initiates a powerful physiological response. Blood vessels on the surface of your skin constrict, and blood is redirected towards your core to protect your vital organs. When you leave the cold, the vessels dilate, and oxygenated, nutrient-rich blood flows back to the periphery, including your skin. This process, along with other complex biochemical reactions, is thought to help modulate the body's inflammatory response.

For many, the most immediate and welcome effect reported is a reduction in itching. The intense cold stimulus on the skin's nerve receptors can have a temporary analgesic, or pain-relieving, effect. It effectively provides your nervous system with a different, powerful sensation to process, which can override and dampen the itch signals being sent to your brain. Breaking the "itch-scratch cycle" is a significant goal in psoriasis management, as scratching can worsen existing plaques and even create new ones. A few minutes of relief from itching can make a substantial difference to your quality of life.

What the Research Shows

Scientific investigation into whole-body cold therapy is a developing field. Direct, large scale studies on its use specifically for psoriasis are not extensive. Therefore, to understand its potential, we must look at research on the general physiological effects of cold exposure and cautiously consider how these might apply.

The fundamental basis of the treatment is the powerful thermal shock to the skin. A thermographic study observed the skin's response to a whole-body cold session, showing that skin temperature drops dramatically and rapidly, particularly on the limbs and trunk [1]. This rapid cooling is the trigger for the cascade of physiological reactions that follow. The extent of this cooling can be influenced by individual factors like body composition and sex [2].

A key area of interest is the influence of cold on inflammation. Psoriasis is driven by inflammatory processes. Research on healthy men who underwent a series of ten whole-body cold sessions measured several markers in their blood. The findings indicated a decrease in the level of interleukin-6 (IL-6), which is a pro-inflammatory cytokine [3]. Cytokines are proteins that signal and regulate the immune system, and IL-6 is known to be involved in the inflammatory cascade of psoriasis. While this study was conducted on healthy individuals, not psoriasis patients, it provides a plausible mechanism for how cold therapy might help modulate inflammatory activity. Reviews of the literature, often focused on athletes, consistently highlight the modulation of inflammatory markers as a primary rationale for using whole-body cold therapy [6, 7].

Another relevant aspect is oxidative stress, which is a state of imbalance between damaging free radicals and the body's ability to counteract them with antioxidants. Oxidative stress is also implicated in the pathology of psoriasis. One study investigated the effect of multiple cold sessions on oxidative stress markers in healthy men. It found that a series of treatments led to a decrease in markers of oxidative damage and an increase in the body's total antioxidant status [8]. This suggests that repeated cold exposure may help bolster the body's natural defence systems against cellular stress.

It is vital to acknowledge the limitations of the current body of research. Many studies use small sample sizes, are conducted over short periods, and often use healthy young men or athletes as subjects [5]. The findings may not be directly transferable to individuals with a chronic autoimmune condition like psoriasis. Furthermore, it is difficult to conduct "blinded" studies where participants do not know if they are receiving the real treatment, which is the gold standard in medical research [5]. Therefore, the evidence should be viewed as preliminary, providing a scientific basis for the effects many users report, but not as definitive proof of clinical efficacy for psoriasis.

Integrating Cold Therapy into Your Psoriasis Care Routine

If you and your doctor agree that whole-body cold therapy is a suitable option for you, it should be approached as one part of a comprehensive self-care strategy. It works best when integrated with your medical treatments and a healthy lifestyle.

An initial series of sessions is often recommended, perhaps ten sessions over two to three weeks. This allows you to assess your individual response. Do you notice a change in the level of itching? Do you feel a greater sense of overall wellbeing? Based on this initial experience, you can decide on a maintenance schedule, which might be one or two sessions a week, or as needed during a flare-up.

It is important to care for your skin before and after a session. You should not apply any creams or ointments immediately before entering the chamber, as your skin must be completely dry. After your session, once your skin has returned to its normal temperature, is an excellent time to apply your prescribed moisturisers or emollients.

Think of your visit to the cold chamber in Memmingen as a dedicated moment for your wellbeing. It is a proactive step you are taking to manage your symptoms. This sense of control can be psychologically beneficial, especially when dealing with a chronic condition. Combining a session with other stress-reducing activities, such as a gentle walk, mindfulness, or simply taking time for yourself, can enhance the overall positive effect.

Frequently Asked Questions

Will whole-body cold therapy cure my psoriasis?

No. Psoriasis is a chronic autoimmune condition with no known cure. Whole-body cold therapy is a non-medical wellness service that may help support the management of symptoms like inflammation and itching, but it does not treat the underlying disease.

How often should I use the cold chamber for my skin?

This is highly individual. Many people start with an initial block of sessions, such as ten sessions over a few weeks, to see how their body responds. After that, a maintenance plan of one to two sessions per week is common, but you should listen to your body and what feels right for you.

Is whole-body cold therapy safe if I have psoriatic plaques?

For intact skin, even with psoriasis plaques, the treatment is generally considered safe as the exposure is very short and the air is dry. However, you should not undergo a session if you have open, cracked, or bleeding plaques. It is essential to discuss this with our trained staff and your dermatologist.

What are the main contraindications for this cold therapy?

You should not use the cold chamber if you have certain medical conditions. These include severe and untreated high blood pressure, a recent heart attack or stroke, deep vein thrombosis, Raynaud's syndrome, cold-activated asthma, or a known allergy to cold (cold urticaria). A full list is available and will be discussed with you.

Why might this type of cold therapy help with the itch of psoriasis?

The intense cold acts as a powerful stimulus to the nerve endings in your skin. This strong signal can temporarily override or "gate" the itch signals being sent to your brain. This can provide a period of relief from the persistent itching, helping to break the itch-scratch cycle.

Do I need a referral from my doctor to try cold therapy?

You do not need a medical referral to use our services at Kältekammer Memmingen, as it is a wellness application. However, we strongly recommend that you discuss your intention to try whole-body cold therapy with your GP or dermatologist to ensure it is a safe and appropriate choice for you.
