Cold Showers for Eczema: Do They Soothe Your Skin

If you are living with eczema (atopic dermatitis), chances are you have been told to avoid hot showers and for good reason. Hot water can strip the skin of essential oils, weaken the barrier, and leave you feeling even itchier than before. But what about the opposite? Could cold showers actually help soothe your skin?

The idea of stepping into a chilly stream of water might sound uncomfortable but more and more people are turning to cold water therapy as a way to calm inflammation, reduce itching, and support the skin barrier. So, does it work for eczema?

In this blog, we explore the science behind cold showers for eczema, their potential benefits, when to avoid them, and how to incorporate them safely into your skincare routine.

Why Hot Showers Worsen Eczema

Let us start with what we know for sure: hot water is a known eczema trigger.

Here is why:

• It strips away natural oils, leading to dryness
• It increases transepidermal water loss (TEWL)
• It temporarily worsens itching and inflammation
• It disrupts the skin’s acid mantle and microbiome

Many dermatologists recommend showering in lukewarm water for no longer than 10 minutes to minimize these effects.

The Science Behind Cold Water Therapy

Cold water therapy, also known as cold hydrotherapy, has been used for centuries across various cultures for its therapeutic benefits. Modern research is now beginning to understand the physiological mechanisms behind these effects, particularly how they relate to inflammatory skin conditions like eczema.

When your skin comes into contact with cold water, several immediate physiological responses occur. Blood vessels constrict in a process called vasoconstriction, which reduces blood flow to the skin’s surface. This not only reduces redness and swelling but also limits the delivery of inflammatory cells and chemicals to the affected areas.

Additionally, cold exposure activates the sympathetic nervous system and triggers the release of norepinephrine, a neurotransmitter that can modulate pain and itch perception. This neurochemical response helps explain why cold water can provide immediate relief from the intense itching that characterizes eczema flares.

Research published in the Journal of Investigative Dermatology has shown that cold temperatures can influence the activity of sensory nerves in the skin, potentially reducing the transmission of itch signals to the brain. This interruption of the itch scratch cycle is crucial for preventing the skin damage that often worsens eczema.

The Case for Cold Showers

Cold water especially at temperatures between 10°C and 20°C (50°F to 68°F) may offer a number of skin benefits, particularly for those with chronic inflammation.

Here is what the science and anecdotal evidence suggest:

Anti Inflammatory Effects

Cold exposure constricts blood vessels, which reduces swelling, redness, and inflammatory activity in the skin. This is why cold compresses are often recommended for acute eczema flares.

A 2022 review in Skin Health and Disease noted that cold water therapy can temporarily suppress the inflammatory response, potentially helping reduce eczema related itching and flare severity.

Itch Relief

A sudden cold shower or rinse can numb nerve endings, which may reduce the intensity of itching (pruritus) associated with eczema. It also distracts the brain with a more acute sensory input, which can interrupt the itch scratch cycle.

Improved Skin Barrier Recovery

Unlike hot water, cold water does not dissolve lipid structures in the skin. That means cold showers may better preserve the natural moisture barrier, especially if followed immediately by moisturizing.

Stress Reduction

Chronic eczema is often worsened by psychological stress. Cold water exposure may trigger a dopamine response and promote nervous system regulation, which could help eczema indirectly by improving resilience to flare inducing stress.

Optimal Temperature Guidelines for Eczema

Finding the right water temperature is crucial for managing eczema symptoms. While individual tolerance varies, most dermatologists recommend specific temperature ranges based on current research and clinical experience.

For daily cleansing, lukewarm water between 33°C and 36°C (91°F to 97°F) is generally considered ideal. This temperature is warm enough to effectively cleanse the skin without causing significant barrier damage or triggering inflammation.

When using cold water for therapeutic benefits, temperatures between 15°C and 20°C (59°F to 68°F) appear to provide the best balance between effectiveness and comfort. Water colder than 15°C may be too shocking for sensitive skin and could potentially trigger adverse reactions in some individuals.

It is important to note that water temperature perception is subjective and can be influenced by factors such as ambient room temperature, individual circulation, and current skin condition. The key is to find a temperature that provides relief without causing discomfort or additional stress to your skin.

Potential Downsides of Cold Showers for Eczema

While cold showers may benefit some, they are not right for everyone or every flare.

Not Ideal If You Have

• Extremely dry, cracked, or broken skin
• Cold urticaria (hives from cold exposure)
• Raynaud’s disease or circulation issues
• A tendency to overreact to temperature extremes

In these cases, lukewarm water is safer and more comfortable.

Seasonal Considerations for Cold Showers

The effectiveness and comfort of cold showers can vary significantly depending on the season and your local climate. Understanding these seasonal variations can help you adjust your approach for optimal results.

During winter months in cold climates, your skin may already be dealing with dry indoor heating and harsh outdoor conditions. In these circumstances, extremely cold showers might be too stressful. Instead, consider using cool rather than cold water, or focus cold exposure only on specific inflamed areas rather than your entire body.

Summer months often bring higher humidity and increased sweating, which can exacerbate eczema for some people. Cold showers during this time can be particularly beneficial for cooling the skin, reducing sweat induced itching, and providing relief from heat related inflammation.

Transitional seasons like spring and autumn may offer the ideal conditions for experimenting with cold water therapy. The moderate outdoor temperatures make it easier for your body to adjust to cold exposure without additional thermal stress.

How to Safely Use Cold Showers for Eczema Relief

If you want to give cold showers a try, follow these dermatologist recommended steps:

Start with Lukewarm Water

Begin your shower with lukewarm water to cleanse the skin gently without irritation.

End with a Cold Rinse

In the last 30 to 60 seconds, gradually reduce the water temperature to cool or cold (not icy). Let it rinse over itchy or inflamed areas, but avoid prolonged exposure.

Pat Dry, Do Not Rub

Use a soft towel to pat your skin dry. Avoid vigorous rubbing, which can irritate sensitive or inflamed areas.

Moisturize Immediately

Within 3 minutes of getting out, apply a thick, fragrance free moisturizer to lock in hydration and reinforce the skin barrier.

Try NellaDerm’s NovaNella Eczema Balm, which contains ceramides and shea butter ideal after showering.

Progressive Adaptation to Cold Exposure

If you are new to cold water therapy, it is important to approach it gradually. Your body needs time to adapt to the physiological stress of cold exposure, and rushing the process can be counterproductive.

Begin with just 15 to 30 seconds of cool water at the end of your regular shower. As your tolerance improves over several days or weeks, gradually increase both the duration and the cold intensity. Most people find that 1 to 3 minutes of cold exposure provides optimal benefits without causing discomfort.

Focus on your breathing during cold exposure. Deep, controlled breaths can help manage the initial shock response and promote relaxation. Many people find that the mental discipline developed through cold exposure also helps them better manage the stress that often triggers eczema flares.

Remember that consistency is more important than intensity when it comes to cold water therapy. Regular brief exposures are generally more beneficial than occasional prolonged sessions that leave you feeling stressed or uncomfortable.

Alternatives to Full Cold Showers

If you are hesitant about full body cold exposure, consider these gentler alternatives:

• Cold compresses on active flare spots
• Cool oatmeal baths
• Cold foot soaks (especially in warm weather)
• Short cool rinses after a normal shower

These options offer similar benefits without the full body shock.

Integrating Cold Showers with Other Eczema Therapies

Cold water therapy should be viewed as a complementary approach rather than a standalone treatment for eczema. When integrated properly with other evidence based therapies, it can enhance your overall management strategy.

After cold showers, your skin may be more receptive to topical treatments. The reduced inflammation and improved blood flow following cold exposure can potentially enhance the penetration and effectiveness of medicated creams, though you should always follow your dermatologist’s specific instructions regarding application timing.

Cold showers can be particularly helpful before applying wet wrap therapy, as the cooling effect can provide immediate itch relief that makes the wrapping process more comfortable. Similarly, using cold compresses before phototherapy sessions may help prepare your skin for light treatment.

It is important to communicate with your healthcare provider about incorporating cold water therapy into your treatment plan. They can provide personalized guidance based on your specific eczema severity, pattern, and overall health status.
