Identifying and avoiding eczema triggers is a crucial step in managing the condition and reducing the frequency and severity of flare-ups. Each person's experience with eczema is unique, and their specific triggers may vary. 


By recognizing the factors that exacerbate their symptoms, individuals can develop personalized strategies for avoiding and overcoming these triggers, ultimately leading to healthier skin and improved quality of life. 


In this article, we will provide a brief overview of common eczema triggers and delve into practical tips for minimizing their impact on your skin.

The Different Eczema Triggers

Eczema triggers can be diverse, ranging from stress to environmental factors, dietary, and other less common triggers. Identifying your specific triggers is an essential step in managing your eczema effectively. To learn more about each trigger, please refer to the following pages:


  • Stress, both physical and emotional, can negatively impact the immune system and trigger or worsen eczema symptoms. 

  • Environmental factors such as pollution, humidity, and temperature changes can influence eczema symptoms.

  • Food can contain allergens, intolerances, and other stressors. 

  • Allergens are substances that trigger an immune response, causing inflammation and worsening eczema symptoms. Intolerances can create stress in the body and lead to an immune response as well. 

  • Irritants are substances that can cause skin inflammation and exacerbate eczema symptoms. 

  • Hormonal fluctuations, such as those experienced during pregnancy, menstruation, or menopause, can trigger eczema flare-ups. 

Once you know which triggers are relevant to your condition, you can tailor trigger avoidance to maximize effectiveness and minimize impact on your life. Read on for actionable strategies to avoid common eczema triggers.

Practical Tips for Avoiding Eczema Triggers

Common eczema triggers include irritants, allergens, stress, environmental factors, pathogens, hormonal changes, and UV exposure. We are going to take them one-by-one and share tips to get started in managing them. 


We start with how to identify which triggers are most important to you.

Identifying Your Personal Triggers

By pinpointing the factors that contribute to your flare-ups, you can develop a targeted approach to avoiding these triggers and improving your skin's health. Here’s how!

Keeping a Symptom Journal

To determine your specific eczema triggers, consider maintaining a symptom journal. Document your daily activities, the products you use, the foods you eat, and any changes in your environment. Note any flare-ups or worsening of symptoms, and look for patterns or correlations between these factors and your eczema. 


We have a guide on how to make that a little easier.

  • Regularly dust your home with a damp cloth to prevent dust build-up.

Reducing Pet Allergy Exposure with Eczema

Animal allergies can trigger eczema flare-ups. See the allergy testing and tracking pages to learn how to identify which animals you might be allergic to. To minimize exposure to allergens from animals:

  • Wash any areas of skin or clothing that have been in contact with allergens.

  • Avoid touching or getting too close to animals or items they have come into contact with.

  • If you want to have a pet but are concerned about allergies, consider less allergenic breeds.

  • If you already live with a pet you are allergic to, limit the pet's access to areas where you spend most of your time.

  • Vacuum frequently with a high-quality vacuum cleaner with a HEPA filter.

  • An air purifier installed in your home could reduce the airborne allergens.

Embracing an Allergy-friendly Diet

Some individuals may experience eczema flare-ups as a result of food allergies or intolerances. To manage food-related eczema triggers:

  • Identify and avoid triggering foods, replacing them with nutritionally comparable alternatives. Consider the tools available in the tracking page to target your energy.

  • When traveling, consider preparing your own food so you know what you are consuming. When abroad, carry a translation of your food allergies or intolerances to ask about ingredients in different languages.

  • Consult a registered dietitian or nutritionist for personalized guidance on creating a balanced, eczema-friendly diet.

See the diet and nutrition page to learn more about how food can be used to improve the skin.

Coping with Stress

Stress can act as an eczema trigger, as it weakens the immune system and aggravates the skin's inflammatory response. To manage stress-related eczema, consider the following tips:

  • Identify the sources of stress in your life, such as work, relationships, or personal issues and consider whether you can reduce the exposure or your sensitivity to each individual stressor

  • Communicate with friends, family, and trusted confidants to explore and address these stressors.(CHA 2021)

  • Develop healthy coping mechanisms, such as exercise, meditation, or engaging in hobbies.

  • Seek professional help, such as therapy or counseling, if necessary.

Keep in mind that it is impossible to eliminate all stress from your life, but developing healthy ways to manage it can help reduce eczema flare-ups. Learn more about mental wellbeing tools and how to exercise with eczema.
