Eczema, also known as atopic dermatitis, is a chronic skin condition that causes inflammation, redness, itching, and irritation. For some people, eczema can flare up unexpectedly and become severe. Severe eczema flare-ups can be uncomfortable and distressing, making it important to understand what causes these episodes. In this article, we will explore the different factors that can trigger severe eczema flare-ups, including environmental, genetic, and lifestyle factors.
What is Eczema?
Eczema is a skin condition that leads to dry, itchy, and inflamed skin. It can appear anywhere on the body but is most common on the hands, elbows, knees, and face. Eczema affects people of all ages, from babies to adults, and is more common in individuals with a family history of skin conditions or allergies. The exact cause of eczema is unknown, but it is believed to result from a combination of genetic and environmental factors.
When the skin’s natural barrier is weakened, it becomes vulnerable to irritants and allergens, which can cause inflammation. This leads to the red, swollen patches of skin that are characteristic of eczema. In some cases, flare-ups can become severe, making the condition harder to manage.
Common Causes of Severe Eczema Flare-Ups
There are several factors that can trigger or worsen eczema flare-ups. These triggers can vary from person to person, so it’s important to pay attention to what causes symptoms to worsen. Below, we discuss the common causes of severe eczema flare-ups.
1. Environmental Allergens
Environmental allergens such as pollen, mold, pet dander, and dust mites are some of the most common triggers of eczema flare-ups. People with eczema often have an overactive immune system that reacts strongly to allergens. When exposed to these allergens, the immune system releases chemicals that cause inflammation in the skin.
For example, pollen from trees, grasses, and flowers can cause allergic reactions in people with eczema. Similarly, mold and pet dander can also trigger flare-ups. Dust mites, tiny insects that live in household dust, are another common allergen that can worsen eczema symptoms.
2. Irritants in Personal Care Products
Many everyday products can irritate the skin and cause eczema flare-ups. Common irritants include soaps, shampoos, detergents, and lotions that contain harsh chemicals, fragrances, or alcohol. These ingredients can strip the skin of its natural oils, leading to dryness and irritation.
For those with eczema, it is important to choose gentle, fragrance-free products. Using mild, hypoallergenic soaps and shampoos can help reduce the risk of flare-ups. Additionally, it’s advisable to avoid products that contain alcohol, as it can dry out the skin.
3. Dry Skin
Dry skin is one of the main factors that contribute to eczema flare-ups. The skin of people with eczema lacks a strong protective barrier, which makes it more susceptible to losing moisture. When the skin becomes dry, it can crack and become inflamed, leading to itching and irritation.
Cold weather, low humidity, and excessive bathing can all cause the skin to dry out. To prevent flare-ups, it is important to keep the skin moisturized. Using thick, emollient creams or ointments can help lock in moisture and protect the skin from dryness.
4. Stress
Stress is another significant trigger for eczema flare-ups. When you’re stressed, your body produces more of the hormone cortisol, which can affect the immune system and increase inflammation. This can lead to skin flare-ups, as the immune system becomes more reactive.
Emotional stress, such as anxiety, anger, or frustration, can also make eczema symptoms worse. For some individuals, stress-related flare-ups can be triggered by changes in routine, work-related pressure, or personal challenges. Finding ways to manage stress, such as through relaxation techniques, mindfulness, or exercise, can help reduce the severity of flare-ups.
5. Food Allergies
Certain food allergies can cause eczema flare-ups, especially in children. Common food allergens include dairy, eggs, nuts, and shellfish. When someone with eczema consumes a food they are allergic to, their immune system may react by causing inflammation in the skin.
It’s important to note that food allergies may not cause eczema flare-ups in all individuals with the condition. However, for those who do have food allergies, it’s important to avoid the triggering foods. Working with an allergist or dermatologist can help identify which foods may be contributing to eczema flare-ups.
6. Heat and Sweating
Heat and sweating are common triggers for eczema flare-ups. Hot and humid weather can cause the skin to become overheated and sweaty, which may lead to itching and irritation. In some cases, sweating can make eczema worse by increasing the moisture in the skin, which can disrupt the skin barrier.
People with eczema should avoid prolonged exposure to hot environments and try to stay cool in the summer months. Wearing loose, breathable clothing made from natural fibers, such as cotton, can help reduce sweating and irritation. Taking cool showers and avoiding hot baths can also help prevent flare-ups.
7. Hormonal Changes
Hormonal changes can play a role in eczema flare-ups, especially in women. Many women report that their eczema symptoms worsen during certain times of their menstrual cycle, particularly during pregnancy or menstruation. This is believed to be due to the hormonal fluctuations that occur during these times.
For pregnant women, the changes in hormone levels can alter the immune system, which can increase the likelihood of eczema flare-ups. Similarly, women using birth control or undergoing hormone therapy may experience changes in their eczema symptoms due to hormonal imbalances.
8. Infection
Infection is a serious concern for people with severe eczema. When the skin becomes damaged due to scratching or dryness, bacteria and viruses can enter the skin, leading to infections. Common infections that can affect people with eczema include staph (Staphylococcus aureus) infections, which can cause pus-filled blisters, and viral infections such as the herpes simplex virus.
Infections can make eczema flare-ups worse and can cause more severe symptoms, such as fever, redness, and increased pain. To reduce the risk of infection, it is essential to keep the skin clean and avoid scratching. If an infection is suspected, it’s important to seek medical treatment as soon as possible.
9. Certain Fabrics and Materials
Certain fabrics, such as wool, synthetic fibers, and rough materials, can cause irritation and trigger eczema flare-ups. These fabrics can rub against the skin, leading to itching and inflammation. Wearing tight or restrictive clothing can also increase the risk of flare-ups.
People with eczema should choose soft, breathable fabrics like cotton and avoid wearing clothes made from wool or synthetic fibers. Wearing loose-fitting clothing can help reduce irritation and prevent flare-ups. It’s also important to wash clothes with gentle, fragrance-free detergents to minimize the risk of irritation.
10. Climate and Seasonal Changes
Changes in climate and seasons can significantly affect eczema symptoms. In colder months, the air becomes drier, which can cause the skin to lose moisture and become more prone to irritation. On the other hand, hot and humid weather can lead to sweating, which may trigger eczema flare-ups.
Seasonal changes, such as the transition from winter to spring or summer to fall, can also affect people with eczema. For instance, springtime may bring about increased pollen levels, while fall may bring cooler and drier air. Monitoring the weather and adjusting your skincare routine can help minimize the impact of climate changes on your eczema.
Managing Severe Eczema Flare-Ups
While eczema flare-ups can be frustrating, there are steps you can take to manage your symptoms and reduce the severity of flare-ups. The key is identifying your triggers and avoiding them whenever possible. Here are some tips for managing eczema:
Moisturize regularly: Apply a thick, fragrance-free moisturizer to your skin every day to help lock in moisture and prevent dryness.
Use gentle, fragrance-free products: Choose soaps, shampoos, and detergents that are free from harsh chemicals and fragrances to reduce irritation.
Take lukewarm baths: Avoid hot water, which can dry out the skin. Add colloidal oatmeal or baking soda to your bath to soothe itching.
Wear soft, breathable clothing: Choose fabrics like cotton that are gentle on the skin and avoid wearing tight or scratchy clothing.
Reduce stress: Practice stress-relieving techniques such as meditation, yoga, or deep breathing exercises to help reduce flare-ups related to stress.
Seek medical advice: If your eczema flare-ups are severe or difficult to manage, consult a dermatologist for treatment options, including prescription creams, antihistamines, or immunosuppressive medications.
Conclusion
Severe eczema flare-ups can be challenging, but understanding the causes can help you manage the condition more effectively. Common triggers such as environmental allergens, irritants in personal care products, dry skin, stress, food allergies, and heat can all contribute to flare-ups. By identifying your specific triggers and making lifestyle adjustments, you can reduce the frequency and severity of eczema flare-ups. If needed, consult with a healthcare professional for additional guidance and treatment options.
