What Triggers Eczema Flare Ups?

Eczema, a chronic skin condition characterized by redness, itching, and inflammation, can have debilitating effects on those who suffer from it. Understanding what triggers eczema flare ups is crucial in managing and alleviating symptoms. While the exact cause of eczema remains unknown, various factors have been identified as triggers, including allergens like dust mites and pollen, irritants such as certain fabrics or harsh soaps, temperature fluctuations, stress, and even certain foods. By identifying and avoiding these triggers, individuals can take proactive steps towards managing their eczema and achieving relief from its distressing symptoms.

Potential Triggers

Living with eczema can be challenging, as flare-ups can occur at any time. Understanding the potential triggers that can set off these episodes is essential to managing the condition effectively. From allergens to irritants, temperature changes to stress, infections to medications, there are various factors that can contribute to eczema flare-ups. In this article, we will delve deeper into each of these potential triggers and explore how they can affect your skin.


Allergens are substances that can cause an allergic reaction in sensitive individuals, and they are a common trigger for eczema flare-ups. Some of the most common allergens associated with eczema include pollen, dust mites, pet dander, and mold. When you come into contact with these allergens, your immune system may respond by releasing chemicals that cause inflammation and itching. This can lead to a flare-up of your eczema symptoms.


In addition to allergens, irritants can also trigger eczema flare-ups. Irritants are substances that can directly irritate your skin and cause inflammation. Examples of irritants that may trigger eczema include soaps and detergents, harsh chemicals, fragranced products, sweat, and even excessive scratching. These irritants can disrupt the skin’s barrier function and increase its sensitivity, making it more prone to eczema flare-ups.

Temperature and Humidity Changes

Changes in temperature and humidity levels can have a significant impact on your eczema-prone skin. Extreme weather conditions, such as hot weather or extreme cold, can dry out your skin and trigger flare-ups. Similarly, low humidity levels can rob your skin of moisture, while high humidity can lead to excessive sweating and increased itching. It is important to protect your skin from these environmental factors by wearing appropriate clothing and maintaining a consistent skincare routine.


Stress is a well-known trigger for a wide range of health conditions, and eczema is no exception. Both emotional and physical stress can contribute to eczema flare-ups. When you are stressed, your body releases stress hormones like cortisol, which can disrupt the balance of your immune system and exacerbate inflammation. Sleep deprivation, often a consequence of stress, can also weaken your immune system and trigger eczema symptoms. Managing stress through relaxation techniques, exercise, and self-care can help prevent flare-ups.


Certain infections can trigger or worsen eczema flare-ups. Bacterial, viral, and fungal infections can all contribute to inflammation and skin irritation. For example, a bacterial infection called Staphylococcus aureus is commonly found on the skin of eczema patients and can lead to more severe symptoms. It is crucial to maintain good hygiene practices and promptly treat any infections to minimize the risk of flare-ups.

Dry Skin

One of the core symptoms of eczema is dry skin, and it can be both a cause and consequence of flare-ups. When your skin lacks moisture, its barrier function becomes compromised, making it more susceptible to irritants and allergens. Factors that can contribute to dry skin and trigger eczema flare-ups include a lack of moisture, excessive cleansing, hot showers, and harsh soaps. Establishing a regular moisturizing routine and using gentle skincare products can help prevent dry skin episodes.

Fragrances and Cosmetics

Fragrances and certain cosmetics can be problematic for individuals with eczema. Perfumes, scented lotions, makeup, and hair products often contain ingredients that can irritate sensitive skin and trigger eczema flare-ups. Fragrances, in particular, can be a common culprit, as they can contain numerous chemicals that are known to cause skin irritation. Opting for fragrance-free products and conducting patch tests before using new cosmetics can help minimize the risk of triggering a flare-up.

Foods and Diet

Although the link between eczema and diet is still under study, certain foods have been identified as potential triggers for flare-ups. Dairy products, gluten, nuts, shellfish, and even sugar have been associated with eczema symptoms in some individuals. It is important to pay attention to any patterns or reactions your skin may have after consuming these foods. Experimenting with an elimination diet or seeking advice from a healthcare professional can help identify any food triggers that may be contributing to your eczema flare-ups.


While medications are typically used to treat various conditions, they can sometimes trigger or worsen eczema symptoms. Antibiotics, antidepressants, pain medications, and blood pressure medications have all been associated with eczema flare-ups in certain individuals. If you suspect that your medication may be contributing to your flare-ups, it is important to consult with your healthcare provider to discuss alternative options or potential modifications to your treatment plan.

In conclusion, identifying and managing potential triggers is crucial in effectively managing eczema flare-ups. Allergens, irritants, temperature changes, stress, infections, dry skin, fragrances and cosmetics, foods and diet, and medications all play a role in triggering or exacerbating eczema symptoms. By understanding these triggers and taking appropriate preventive measures, you can help minimize the frequency and severity of flare-ups, allowing you to better manage your eczema and enjoy healthier, happier skin.
