Eczema Triggers: 15 Common Causes and How to Gently Avoid Them

TL;DR: Eczema flare-ups can feel unpredictable, but they are often caused by specific triggers in your environment, diet, or daily routine. Common culprits include dry air, harsh soaps, stress, and certain fabrics. By gently identifying and avoiding your personal triggers, you can take back control and give your skin the calm it deserves.

One of the most challenging parts of living with eczema is the feeling that a flare-up can happen at any moment, without warning. One day your skin is calm and comfortable, and the next, it’s red, itchy, and inflamed. It can feel like a mystery, but often, there’s a specific trigger behind that sudden change.

Think of yourself as a skin detective. By learning to recognize the common culprits and paying gentle attention to how your skin responds, you can start to connect the dots. This knowledge is empowering—it allows you to move from reacting to flare-ups to proactively creating an environment where your skin can thrive.

Let’s explore some of the most common eczema triggers and discuss gentle, practical ways to navigate them.

Common Eczema Triggers and How to Manage Them

Your skin is unique, and what triggers a flare-up for one person might not affect another. Here are 15 common triggers to be mindful of.

Environmental Triggers

1.  Dry Air: When the air lacks humidity (hello, Canadian winters!), it draws moisture directly from your skin, leaving it dry, tight, and vulnerable to flares.  

• Gentle Solution: Use a humidifier in your bedroom and main living areas to add moisture back into the air. And, of course, moisturize your skin diligently with a rich, natural cream.

2.  Seasonal Changes: The shift from warm to cold weather, or vice versa, can be tough on sensitive skin.  

• Gentle Solution: Adjust your skincare with the seasons. You might need a thicker cream in the winter and a lighter one in the summer. Be extra attentive to your skin during these transitional periods.

3. Pollen, Dust Mites, and Pet Dander: These common allergens can land on your skin and set off an inflammatory response.  

• Gentle Solution: Wash your bedding in hot water weekly, use allergen-proof mattress and pillow covers, and vacuum regularly with a HEPA filter. After playing with a pet, wash your hands and change your clothes.

Household Triggers

4. Fragrances: Artificial scents in perfumes, lotions, candles, and air fresheners are a major irritant for many.  

• Gentle Solution: Choose fragrance-free products whenever possible. Look for skincare, laundry detergent, and cleaning supplies that are labelled “fragrance-free.”

5. Harsh Soaps and Detergents: Many conventional soaps and laundry detergents contain sulfates and other chemicals that strip the skin of its natural protective oils.  

• Gentle Solution: Opt for gentle, pH-balanced, and dye-free cleansers and laundry detergents. Look for products designed for sensitive skin.

6.  Household Cleaners: The chemicals in many cleaning products can be very irritating to the skin.  

• Gentle Solution: Wear gloves when cleaning. Better yet, switch to natural cleaning solutions made from ingredients like vinegar and baking soda.

Personal Care Triggers

7.  Hot Water: A long, hot shower might feel good in the moment, but it strips your skin of its essential oils, leading to dryness and itching.  

• Gentle Solution: Stick to short, lukewarm baths or showers (5-10 minutes). Pat your skin gently dry and moisturize immediately.

8.  Sweat: The salt and pH of sweat can be irritating to eczema-prone skin.  

• Gentle Solution: After exercising or on a hot day, rinse off in a cool shower as soon as you can. Wear loose-fitting, breathable clothing that wicks moisture away from your skin.

9.  Certain Fabrics: Scratchy wool and non-breathable synthetic fabrics like polyester can trap heat and irritate the skin.  

Gentle Solution: Choose soft, natural fibres like 100% cotton, bamboo, or silk. Layering is a great way to stay warm without relying on irritating fabrics.

Internal & Lifestyle Triggers

10. Stress: The mind-skin connection is powerful. When you’re stressed, your body releases hormones like cortisol, which can trigger inflammation in the skin.  

• Gentle Solution: Find a stress-management practice that brings you joy. This could be a quiet walk in nature, gentle yoga, meditation, or simply carving out 10 minutes a day for a cup of tea and a good book.

11. Hormonal Changes: Some women notice their eczema flares up around their menstrual cycle, during pregnancy, or in perimenopause due to fluctuating hormone levels.  

• Gentle Solution: Be extra diligent with your skincare routine during these times. A little extra moisturizing and self-care can go a long way.

12. Food Sensitivities: For some people, certain foods can trigger an inflammatory response. The most common culprits are dairy, eggs, gluten, soy, and nuts.  

• Gentle Solution: If you suspect a food trigger, speak with a healthcare provider or a registered dietitian. They may recommend an elimination diet to safely identify any sensitivities. Don’t make drastic dietary changes without professional guidance.

13. Illness: When your body is fighting off a cold or the flu, your immune system is in overdrive, which can sometimes lead to an eczema flare-up.  

• Gentle Solution: Focus on rest and recovery. Keep your skin well-moisturized and be extra gentle with it until you’re feeling better.

14. Scratching: It’s an itch-scratch cycle. The more you scratch, the more inflamed your skin becomes, and the more it itches.  

• Gentle Solution: This is the hardest one! Keep your nails short. When you feel an itch, try to gently tap or press on the area instead of scratching. Applying a cool compress or a soothing cream like Orellis can provide instant relief and break the cycle.

15. Using the Wrong Products: Even products that claim to be for “sensitive skin” can contain hidden irritants.  

• Gentle Solution: Become a label-reader. Choose products with simple, natural ingredient lists. Our Orellis Natural Eczema Cream is free from steroids, parabens, and artificial fragrances. It’s Health Canada-approved and made with scientifically-backed ingredients like Colloidal Oatmeal, so you can trust that you’re giving your skin the gentle, effective care it needs.

Your Path to Calm Skin

Identifying your triggers is a journey of gentle observation. Try keeping a small journal for a few weeks. Note what you ate, what you wore, your stress levels, and how your skin felt each day. You might start to see a pattern emerge.

By understanding and avoiding your triggers, and by embracing a consistent, natural skincare routine, you can empower yourself to manage your eczema with confidence and grace.

Frequently Asked Questions

Q: How can I tell what my specific triggers are?

A: Keeping a “skin diary” is the best way. For a few weeks, jot down your daily activities, the foods you eat, the products you use, and your stress levels. Note any changes in your skin. Over time, you’ll likely notice a connection between certain factors and your flare-ups.

Q: If I avoid all these triggers, will my eczema go away forever?

A: Avoiding triggers is a powerful management strategy that can significantly reduce the frequency and severity of your flare-ups. While it may not “cure” eczema, it can lead to long periods of clear, comfortable skin and give you a wonderful sense of control over your skin’s health.

Q: Can the weather in Canada really affect my eczema that much?

A: Yes, absolutely. The dry, cold air of Canadian winters is a major trigger for many people because it strips moisture from the skin. Conversely, the heat and humidity of summer can cause sweating, which can also be an irritant. Using a humidifier in the winter and wearing breathable fabrics in the summer are key Canadian strategies!
