What Are Eczema Triggers?

Eczema triggers are external or internal factors that can cause your skin to flare up, itch, and become inflamed. While common triggers like fragrances and certain foods are well known, many people continue to suffer because they overlook less obvious causes. Understanding these hidden triggers can be the key to managing your eczema more effectively—and preventing painful outbreaks.

1. Stress – A Silent Skin Saboteur

You might not associate your emotional state with your skin, but stress is one of the most overlooked eczema triggers. Chronic stress can cause inflammation throughout the body, weakening the skin barrier and making you more susceptible to flare-ups.

Pro tip: Incorporate stress-reducing techniques like mindfulness or gentle yoga into your routine.

2. Hard Water and Chlorine

If you’ve recently moved or changed water sources, your eczema might suddenly get worse. Hard water contains minerals like calcium and magnesium that can irritate sensitive skin. Likewise, frequent swimming in chlorinated pools can strip your skin of moisture and disrupt the microbiome.

3. Fabrics You Wear Daily

Clothing may seem harmless, but synthetic fibers like polyester or even wool can trap heat and moisture, irritating eczema-prone skin. Even some “soft” fabrics can cause micro-abrasions or allergic reactions.

Try This Instead:

Stick to breathable, natural fabrics like 100% cotton or bamboo. Always wash new clothes before wearing them with fragrance-free detergent.

4. Skincare Ingredients That Seem “Natural”

Just because it’s natural doesn’t mean it’s safe for eczema. Essential oils like tea tree, citrus, or peppermint can be overly harsh for compromised skin. Even alcohol-based ingredients found in toners or acne treatments can exacerbate dryness and irritation.

5. Hormonal Shifts

Hormonal changes during puberty, pregnancy, or menopause can cause eczema to appear or worsen. The imbalance can affect the skin’s oil production and barrier function, leaving it more vulnerable.

If you’re noticing flare-ups around your menstrual cycle or postpartum period, hormones could be the culprit.

6. Indoor Allergens

We often think of pollen and dust as seasonal annoyances, but indoor allergens like pet dander, mold, and dust mites are constant eczema triggers. These can worsen symptoms without you even realizing it—especially if your home isn’t well-ventilated.

✅ Pro tip: Use allergen-proof covers for mattresses and wash bedding in hot water weekly.

7. Over-Cleansing

Yes, too much hygiene can be harmful. Washing your face or body multiple times a day with strong soaps can strip your natural oils, damaging your skin barrier.

Stick to short, lukewarm showers and use mild, fragrance-free cleansers that support your skin’s pH balance.

How to Identify and Manage Your Eczema Triggers

Identifying personal eczema triggers can take time, but keeping a flare-up diary can help. Record what you eat, use on your skin, your stress levels, and environmental changes. This helps pinpoint patterns and eliminate specific causes.

Here are some additional management tips:

• Use a daily moisturizer designed for sensitive skin.

• Avoid sudden temperature changes.

• Wear protective gloves when cleaning or washing dishes.
