Why eczema keeps flaring: a naturopathic view of the skin and body

Flowers coming through a crack in a wall indicating beauty, resilience and healing

If you have been managing eczema for years and still feel as though you are one step behind it, it can be exhausting.

The dryness, redness, itching, weeping, cracking and discomfort are all happening at the surface. This is the part that can be seen, felt and managed day to day. It is also the part that often causes the most distress, especially when sleep is affected, the skin feels painful, or flares seem to come out of nowhere.

But eczema rarely exists in isolation.

The skin is where the symptoms are showing, but it is closely connected to the immune system, gut, nervous system, hormones, nutrient status, environment and the body’s wider inflammatory response. When some of these systems are under pressure, the skin may become more reactive, slower to repair, and more easily triggered.

From a naturopathic perspective, eczema is not seen as a collection of random flares. It is seen as a pattern. The work is to understand what the skin may be responding to, what the body may need more support with, and how to reduce the load on the system without making life feel smaller.

The skin is part of the immune system

The skin is often described as a barrier, but it is much more active than that.

It helps protect the body from irritants, allergens, microbes, chemicals and environmental exposures. It communicates with the immune system, responds to stress signals, produces antimicrobial compounds, and plays a role in repair.

When the skin barrier is working well, it helps keep moisture in and irritants out. When it is compromised, the skin loses water more easily and becomes more vulnerable to everyday exposures such as soaps, detergents, fabrics, pollen, dust mite, sweat, heat, skincare products or infection.

This is why barrier support is such an important part of eczema care. But the barrier does not operate in isolation. It is influenced by nutrition, inflammation, allergies, microbes, sleep, stress and the environment around the person.

So while topical care can be essential, it is only one part of the picture.

The immune system may be on high alert

Eczema commonly sits within an atopic pattern. Some people also experience asthma, hay fever, food allergies, environmental allergies or histamine-type symptoms.

This does not mean every eczema case is allergy-driven. It does mean the immune system is often involved.

In eczema, the immune system may respond strongly to things that would not usually create such a visible reaction. This might include pollen, dust mite, animal dander, mould, foods, microbes on the skin, heat, stress, sweat or certain topical products.

In clinic, I am interested in what may be keeping the immune system on alert.

For one person, this may be a clear allergy picture. For another, it may be recurrent infections, poor sleep, gut symptoms, nutrient depletion, hormonal changes, stress, or a skin barrier that is constantly exposed to irritants.

The aim is not to switch the immune system off. It is to understand why it may be reacting so strongly, and where regulation may need support.

The skin barrier needs nourishment, not just moisturising

Moisturisers and emollients can be important in eczema, especially when the skin is dry, cracked, sore or struggling to hold moisture. But skin repair also depends on what is available beneath the surface.

The body needs enough protein, essential fatty acids, zinc, vitamin D, vitamin A, magnesium, selenium, iron and other nutrients to repair well. It also needs sleep, hydration, balanced inflammation and a calmer immune environment.

When someone has a restricted diet, poor appetite, digestive symptoms, food allergies, picky eating, heavy menstrual bleeding, low vitamin D, low iron, or a higher inflammatory load, the skin may not have everything it needs to repair efficiently.

This is why I often look at food intake, nutrient status and digestion alongside topical care.

The question is not only: “What can we put on the skin?”

It is also: “Does the body have what it needs to rebuild?”

The gut-skin connection, without the oversimplification

Many people come across the idea that eczema “starts in the gut”. Sometimes gut health is highly relevant. Sometimes it is only one part of a much wider picture.

The gut and skin communicate through the immune system, microbial metabolites, inflammation, histamine balance and nutrient absorption. A large part of the immune system sits around the digestive tract, where it is constantly interacting with food, microbes, allergens and the outside world.

A more resilient gut environment may help the immune system respond more appropriately. An irritated or depleted gut environment can sometimes add to the overall inflammatory load that shows up in the skin.

I tend to look more closely at gut health when there are digestive symptoms such as bloating, constipation, loose stools, reflux or abdominal discomfort, especially where this sits alongside food reactions, recurrent infections, frequent antibiotic use, or a history of restricted eating.

In babies and children, birth history, feeding history, weaning, antibiotic exposure, stool patterns, recurrent infections and family history of allergy can all add useful context.

In adults, I may also consider stress, medication history, hormonal changes, long-term digestive symptoms, alcohol intake, food tolerance and whether skin flares seem to track alongside changes in digestion.

Gut support does not mean eliminating everything or reducing the diet down to a small list of “safe” foods. More often, it is about building a steadier internal environment so the immune system has less to react to, and the body has better access to the nutrients needed for repair.

That might involve improving fibre intake, supporting regular bowel movements, increasing plant diversity, using specific probiotics or prebiotics where appropriate, improving protein and mineral intake, and identifying foods that are clearly aggravating symptoms without unnecessarily restricting the diet.

The nervous system and the itch-scratch cycle

Eczema is not caused by stress alone, but the nervous system can have a significant effect on inflammation, itch and skin repair.

When someone is itchy, sleep-deprived, inflamed or uncomfortable, the nervous system often becomes more alert. The body may find it harder to rest, repair and settle.

Over time, this can become a difficult loop.

Itch affects sleep. Poor sleep increases inflammation and reduces tolerance. Stress chemistry can intensify itch. Scratching damages the barrier further. The skin becomes more reactive. The person becomes more vigilant. The body has fewer opportunities to recover.

For children, this may show as disturbed sleep, irritability, bedtime flares, sensory sensitivity or difficulty settling.

For adults, it may show as night-time itching, flares after intense work periods, emotional exhaustion, or a sense that the skin reacts more when the body is under pressure.

Supporting the nervous system can be a helpful part of eczema care because itch, inflammation, sleep and stress physiology are so closely connected.

That might mean supporting sleep, reducing the intensity of itch-scratch cycles, creating steadier routines, improving blood sugar balance, building in rest, and helping the body feel less under threat.

Everyday exposures can keep the skin reactive

Sometimes the most useful changes are very practical.

The skin is constantly interacting with the outside world. Laundry products, fragranced skincare, body wash, household cleaners, make-up, hand sanitiser, swimming pools, synthetic fabrics, overheating, sweat, pets, dust mite, mould and pollen can all affect eczema.

For some people, one exposure is obvious. For others, it is the total load that matters.

A child may tolerate a food well most of the time, but flare when it is combined with poor sleep, pollen season and a viral infection. An adult may cope with stress until it overlaps with hormonal change, a new skincare product and a busy period at work.

This is where the pattern matters more than one isolated trigger.

The aim is not to make life smaller or remove everything, but to reduce unnecessary irritation where possible, so the skin has fewer signals to respond to.

Hormones can shift the terrain

Hormones can influence the skin barrier, immune activity, histamine, inflammation, sleep and stress tolerance.

Some people notice eczema changes before a period, during pregnancy, after birth, while breastfeeding, during perimenopause, or when using or changing hormonal medication.

Hormones may not be the main driver, but they can change the terrain the skin is operating in.

In adults, I may consider whether flares are linked with the menstrual cycle, perimenopause, poor sleep, night sweats, heavier bleeding, mood changes, migraines, histamine symptoms or changes in skin dryness.

Where hormones are part of the picture, support may include nutrient status, blood sugar balance, sleep, stress physiology, bowel regularity and the body’s natural clearance pathways.

A naturopathic view of eczema

Naturopathic medicine views eczema as a whole-person picture.

The skin matters. Topical care matters. Medical treatment may matter. But the person beneath the skin matters too.

A naturopathic approach looks at the barrier, immune system, gut, nutrients, nervous system, sleep, hormones, environment and life context. It asks what the skin is responding to, what the body may be lacking, and where support could make the biggest difference.

This is not about searching endlessly for triggers or making eczema feel more complicated than it already is. It is about building a clearer, more personalised understanding of the skin and body, so support feels practical, steady and genuinely useful.

Why this changes the way we support eczema

When eczema is treated only as a skin problem, support can become very reactive.

A flare appears, so something is applied. The itch worsens, so another layer of symptom control is needed. The skin settles briefly, then flares again when the same wider pattern is still present.

Sometimes medical support is needed and appropriate. Many people use emollients, topical steroids, topical calcineurin inhibitors, antihistamines, antibiotics, phototherapy or biologic medications, and these can be important tools, especially when the skin is infected, severely inflamed, painful or affecting sleep and quality of life.

Naturopathic care can sit alongside these approaches by looking at what else may need support around the skin: the barrier, immune system, gut, nutrients, sleep, nervous system, hormones and environment.

That could include strengthening the skin barrier, reducing avoidable irritants, supporting gut resilience, improving nutrient status, clarifying allergies or triggers, supporting sleep, reducing histamine load, improving recovery after infections, or supporting hormonal transitions where relevant.

The treatment plan does not need to address everything at once. It needs to identify the most useful next steps.

What progress may look like

In eczema, progress can be gradual, and the first signs of change are not always visible on the skin.

When eczema has been present for some time, change often comes through steady, layered support. Sometimes the earliest signs are more subtle: sleeping for longer stretches, feeling less wired, recovering more quickly after a trigger, having more settled digestion, fewer infections, steadier mood, or itch that feels less intense and easier to interrupt.

These shifts matter. They suggest the system is becoming less reactive and more able to repair, even while the skin is still finding its way back to balance.

Over time, flares may become less intense, recovery may feel quicker, and the skin barrier may become more resilient.

Bringing the whole skin picture together

Eczema is not just a skin problem because the skin is not separate from the rest of the body.

It is influenced by the immune system, gut health, nutrient status, stress physiology, sleep, hormones, allergens, microbes, irritants and the environment around the skin.

A naturopathic approach brings these pieces together. It supports the skin from the outside, while also looking at what may be driving inflammation and reactivity from within.

The aim is to help the skin and body become calmer, stronger and more resilient, with support that is individual, realistic and manageable.

Frequently asked questions

Can gut health affect eczema?
Yes, in many cases. The gut and skin are connected through the immune system, inflammation, microbial activity and nutrient absorption. Gut health is not the cause of every eczema case, but it is often worth assessing, particularly when there are digestive symptoms, a history of antibiotic use, food reactions, or recurrent infections.

Is eczema linked to the immune system?
Closely. Eczema commonly involves an over-reactive immune pattern, where the body responds strongly to exposures that would not usually trigger such a visible reaction. From a naturopathic perspective, supporting immune regulation is often an important part of longer-term eczema care.

Why does eczema flare with stress?
Stress can affect the nervous system in ways that intensify itch, increase inflammation and disrupt sleep. This can create a self-reinforcing cycle: itch disturbs sleep, poor sleep reduces tolerance, and the skin becomes more reactive. Nervous system support can be a meaningful part of helping the body settle.

Why does eczema keep coming back?
Eczema often keeps coming back when the skin is still being exposed to the same internal or external pressures. This might include a fragile skin barrier, allergy patterns, gut symptoms, nutrient gaps, poor sleep, stress load, hormonal shifts or everyday irritants. The pattern is different for each person, which is why personalised assessment matters.
