Managing Eczema Flare-ups Across Seasons

Managing Eczema Flare-ups Across Australian Seasons

You’ve finally got your skin settled, then the first cold snap arrives, the heater goes on, and the itch comes back. Or the grass starts flowering in spring and your arms and face flare up. For many Australians with eczema, the calendar is a trigger in itself.

This article explains why the seasons affect eczema, how people commonly adjust their routines, and where the evidence stands on different approaches. It is general education only, not medical advice.

Why the seasons affect eczema

Eczema is closely linked to a weakened skin barrier, the outermost layer of the skin (the stratum corneum). When that barrier is compromised, moisture escapes more easily through the skin, which is known as transepidermal water loss. Changes in weather can speed this up.

Eczema is common here. A frequently quoted figure is that around 30% of Australian children are affected, so many families are dealing with seasonal flares.

Australia also isn’t one climate. Humid summers in the tropical north are very different from dry, cold alpine winters in Victoria or Tasmania, so what triggers your skin may differ from what triggers someone in another state. Your own pattern matters more than a generic seasonal rule.

Autumn and winter: dry air and indoor heating

Cold winds, low humidity and indoor heating all pull moisture out of the skin during the cooler months. For skin with a weakened barrier, that can mean more dryness, tightness and itch.

Australian guidance suggests applying a thick, fragrance-free emollient within three minutes of bathing to help lock in hydration. Other commonly recommended habits include:

• Taking short, warm (not hot) showers
• Using soap-free cleansers
• Wearing breathable cotton clothing

A practical example: someone who has used a light lotion all summer might notice their skin feeling tight by May. Many people find it useful to raise this at their next GP or pharmacist visit and ask whether their routine needs adjusting for winter, rather than guessing.

Spring: pollen and the skin

Most people think of pollen as a hay fever problem affecting the nose and eyes. But airborne triggers, particularly grass pollen, can also land directly on exposed skin such as the face and arms.

In people with a disrupted skin barrier, pollen may be able to get through the outer layer and stimulate a localised immune response. That helps explain why some people notice skin flares during pollen season even when their nasal symptoms are mild.

A practical example: if your skin tends to flare after weekends at the park or a windy day outdoors in spring, it may be worth noting this in a diary and sharing it with your doctor. A common-sense step is showering and changing clothes after spending time outdoors, though this is a general habit rather than a proven fix for any individual.

Summer: heat, sweat and swimming

When temperatures climb above about 30°C, sweat can accumulate on the skin. Sweat contains salts that may irritate raw or already inflamed skin, so hot, humid days can be difficult, particularly in the tropics.

Swimming is a mixed bag. Pool or sea water seems to soothe some people’s skin and irritate others’. Clinical bodies generally recommend rinsing with fresh water after swimming and applying an emollient straight afterwards.

A practical example: after a beach trip, a quick fresh-water rinse and moisturiser at the change rooms or at home, rather than leaving salt and chlorine to dry on the skin, fits that advice. A lighter routine in summer may suit some people, but this is worth confirming with a health professional.

What the evidence says: three categories

Not everything people try for eczema has the same level of support. Here is how the research separates it.

Proven or approved approaches

• Daily fragrance-free emollients to support the skin barrier
• Non-soap body washes
• Avoiding known environmental triggers
• Prescription topical therapies, used under the supervision of a doctor or pharmacist

Early research

These areas are still being investigated and shouldn’t be treated as established options:

• Topical products designed to balance the skin microbiome
• Controlled pollen chamber studies looking at how pollen proteins penetrate skin with a weakened barrier (including in people with filaggrin deficiency)
• Applying lipid-based barrier products before exposure to triggers

Traditional or anecdotal use

Some people use colloidal oatmeal baths, dilute vinegar soaks or herbal salves such as calendula. These have a history of home use, but they lack formal regulatory approval as primary eczema treatments. They can occasionally cause contact sensitivity in reactive skin. If you’re considering any of them, check with a practitioner first.

Build a plan with your doctor: the ASCIA eczema plan

Lifestyle tweaks are useful, but they work best alongside a structured plan. The Australasian Society of Clinical Immunology and Allergy (ASCIA) recommends that people establish an individualised ASCIA Stepwise Management Plan for Eczema with a qualified doctor. It sets out how to manage daily care and how to respond to flares safely.

It’s worth discussing the plan before the seasons change, so you know what your routine looks like in winter, spring and summer and what to do if skin worsens.

When to see a health professional

See a GP, dermatologist or pharmacist if:

• A flare is severe or isn’t settling with your usual routine
• You suspect a skin infection on top of the eczema
• You’re unsure whether a product or home remedy is safe for your skin
• You’d like to set up or update a management plan

FAQ

Can pollen really affect my skin, not just my nose?

According to the research, airborne grass pollen can contact exposed skin and, where the barrier is weakened, may trigger a local immune response. Studies exploring this are still developing.

Should I use the same moisturiser all year?

Many sources suggest richer emollients in cooler months and lighter routines in summer. Your GP or pharmacist can help you work out what suits your skin.

Are oatmeal baths or vinegar soaks safe?

They have a traditional history, but they aren’t approved as primary treatments and can cause reactions in sensitive skin. Check with a practitioner first.

Is swimming bad for eczema?

It varies. Some people find it soothing and others find it irritating. Rinsing with fresh water and applying emollient afterwards is the usual advice.

Conclusion

Eczema flares often follow the seasons, but they don’t have to catch you off guard. Dry winter air, spring pollen and summer sweat each stress the skin barrier in different ways, and where you live in Australia shapes which one matters most. Sticking with well-supported basics, being cautious with traditional remedies and early-stage ideas, and working through an ASCIA management plan with your doctor or pharmacist is a sensible way to prepare for the year ahead.
