When Spring Hits the Skin
By Keili Mistovich, MD, MPH, FAAP, Zest Chief Medical Officer, Zest Pediatrics of Beachwood
Let’s be honest: there is no easy season for kids with eczema, allergies, or asthma. Winter brings dry indoor air, respiratory viruses, and cold temperatures that strip the skin and irritate the airways. And then spring arrives — and instead of relief, it brings something different. Pollen. More time outdoors with more activities. Shifting life routines. A new set of triggers layered on top of an immune system that has already been working hard for months.
What I see every spring in my practice is families who have been managing well, working hard to do everything they can to survive cold and flu season, and then suddenly feel like they are back at square one. The skin flares again. The cough returns. The sneezing and itchy eyes are relentless. Spring has arrived. And for kids whose immune systems are already wired toward reactivity, spring brings trouble.
It’s All Connected — And That’s the Point
Eczema, seasonal allergies, and asthma aren’t three separate problems that happen to show up in the same child. They share underlying immune pathways — a pattern of reactivity that runs through all of them. When the immune system is taxed — by pollen, by poor sleep, by processed food, by stress — it shows up wherever that child’s vulnerability lives. For some kids, it’s the skin. For others, it’s the nose and eyes. For others, it’s the airways. For many, it’s all three. However, understanding this is actually freeing, because it means that the steps that support one system tend to support all of them.
The outer layer of the skin acts as a protective barrier, and in kids with eczema, that barrier has gaps — moisture escapes, and environmental triggers like pollen penetrate more easily and set off an immune response. Research has confirmed that pollen doesn’t just affect the nose; it lands on exposed skin and can trigger flares directly. In the airways, a similar dynamic plays out: allergen exposure drives inflammation that causes irritation and swelling in the airways and increases reactivity. These are different expressions of the same underlying immune sensitivity, and they all respond to the same foundational support.
What Actually Helps
The gut-immune connection. One of the things we don’t talk about enough in managing atopic disease — eczema, allergies, asthma — is the gut. A significant portion of the immune system lives in the digestive tract, and the health of the gut microbiome directly influences how the immune system responds to environmental triggers and stress. Diets rich in whole foods, fiber, and variety support a more diverse and resilient microbiome. Fermented foods like yogurt, kefir, and sauerkraut introduce beneficial bacteria. We’re also learning more about the role of specific probiotic strains in atopic disease — the evidence is still evolving, but it’s promising enough to be worth a conversation with your doctor, especially if your child has been on multiple courses of antibiotics.
Anti-inflammatory nutrition. Most kids with eczema or allergies do not need broad elimination diets — and unnecessary restriction can create more problems than it solves, both nutritionally and emotionally. What does matter is the overall pattern of eating. Omega-3 fatty acids, found in fatty fish, walnuts, chia, and flaxseed, have been studied for their role in reducing the kind of low-grade inflammation that underlies atopic disease. A diet heavy in processed foods and added sugars does the opposite — it promotes inflammation. Shifting the balance toward whole foods, varied vegetables, and adequate protein is one of the most consistent things a family can do to support immune regulation over time.
Sleep as a regulator. Sleep is where the immune system does a lot of its most important work — calming inflammation, clearing waste from our systems, and restoring balance. When sleep is disrupted — by itch, by congestion, by an overactive nervous system — inflammation increases, and the skin and airways become more reactive. It’s a cycle that is hard to break from the outside in. Consistent sleep and wake times, a dim and calm evening environment, and good symptom management at night (so the itch or the congestion isn’t the thing waking them up) are not small details.
The nervous system matters. Stress and anxiety genuinely amplify immune reactivity. The nervous system and the immune system communicate constantly, and a child who is anxious, overwhelmed, or going through a hard transition will often flare — in their skin, their nose, their breathing — more than a child who feels regulated and safe. This doesn’t mean stress causes eczema or asthma. It means it makes it more likely for the immune system to become increasingly reactive. Predictable routines, time outdoors, movement, and true downtime are not just recommendations.
Targeted supplements worth knowing about. Vitamin D deficiency has been associated with increased atopic disease severity — and given how little sun most kids get in winter and early spring, levels are worth periodically checking. Quercetin, a flavonoid found naturally in apples, onions, and berries, has natural antihistamine and anti-inflammatory properties and is increasingly being studied in the context of allergic disease. Fish and algae oil, as a concentrated source of omega-3s, are also helpful in calming over-reactivity in our immune systems. These supplements are not replacements for conventional treatment of atopic disease in our kids — they are extra layers of support. Always talk with your doctor about dosing and quality before starting any supplement.
Reduce the environmental load. On high pollen days, rinse off exposed skin after outdoor play, change clothes when coming inside, and keep windows closed during peak pollen hours. Keep bedding washed regularly, especially pillowcases. For kids with asthma, make sure inhalers are accessible and that the controller medication plan — if there is one — is being followed consistently as the season changes. These are not complicated interventions, but they reduce the cumulative burden on an immune system that is already working harder than usual.
The Goal Isn’t Perfect Control
Spring is a harder season for these kids. That is real, and it is worth acknowledging. But it is also a predictable one, and predictable means you can prepare. When you support the whole system — the gut, the sleep, the stress, the nutrition, the environment — rather than just chasing each individual symptom, you give your child’s body a better chance to hold its own.
And when symptoms are persistent, worsening, or disrupting daily life, please reach out. The goal isn’t to manage this alone or to push through. The goal is a child who feels well in their body — breathing easily, sleeping through the night, and comfortable in their own skin.
