Eruption of Eczema: Understanding the Causes and Triggers of Eczema
Eczema, a common skin condition characterized by itchy, inflamed skin, can be triggered by a variety of environmental factors, lifestyle choices, and allergens. Understanding these triggers can help individuals manage their symptoms and reduce flare-ups.
Common environmental irritants and allergens that can provoke eczema flare-ups include dust mites, pet dander, pollen, molds, and certain fabrics like wool or synthetic materials [1][3]. Weather conditions also play a significant role, with both dry, cold weather and humid seasons potentially causing flare-ups [3][5]. Other triggers include soaps, detergents, fragranced skincare products, hot showers, excessive sweating, and pollutants [1][3]. Emotional stress, anxiety, and depression are recognized lifestyle triggers that can exacerbate eczema symptoms [1][2][3].
Allergens such as dust mites, pet dander, and pollen are common environmental factors that irritate the skin in susceptible individuals [3][5]. In some cases, food triggers may contribute, especially in children [3]. Food sensitivities may cause eczema to worsen if certain foods are consumed [16]. However, there is currently no evidence that specific foods cause eczema, although individuals may have allergic reactions to specific foods [29].
To minimize the effects of dust mites, it is recommended to use dust mite covers on pillows and mattresses, wash bedding weekly in hot water with a fragrance-free detergent, limit the use of rugs, curtains, plush toys, and soft furnishings, and dust and vacuum the home regularly [21]. To limit exposure to pollen, individuals can monitor the pollen count in their area, keep doors and windows shut as far as possible, use air-conditioning, limit time outdoors, ask someone else to mow the lawn, and stay away from the lawn for 2 hours after mowing [26].
Stress, changes in air temperature and humidity, and hormonal changes can also trigger eczema flare-ups [24][36]. To prevent sunburn or sun exposure, a fragrance-free, broad-spectrum sunscreen of at least SPF30 can be applied, and individuals should stay in the shade where possible, wear clothes that protect the head, face, and body from the sun [28].
Identifying triggers can help individuals manage their eczema and reduce symptoms. A dermatologist can help identify the type of eczema an individual has and prescribe treatments that may be more effective [33]. If a rash appears suddenly, spreads quickly, or shows signs of infection, a person should contact a doctor as soon as possible [34]. If a person has noticed their eczema has worsened or is no longer responding to their usual treatment, they may benefit from speaking with a doctor or dermatologist [32].
In some cases, dietary changes may help manage eczema symptoms. Some people find it beneficial to cut out foods containing white flour, gluten, and nightshades, such as tomato, but increase the overall intake of vegetables, organic foods, and oily fish [35]. However, more research is needed, and individuals should speak with a doctor before changing their diet.
In summary, eczema flare-ups typically result from a combination of environmental irritants and allergens, weather extremes, lifestyle-related stress, and physical skin barrier disruptions [1][2][3][5]. Managing eczema often involves identifying and avoiding these triggers where possible.
- A naive approach to managing eczema might dismiss the impact of environmental factors on flare-ups, but understanding these triggers can help individuals take control of their symptoms.
- Moderate to severe cases of eczema may require established medical-conditions treatments to provide relief, but some individuals find more moderate relief through changes to their health-and-wellness routine.
- Emotional stress, anxiety, and depression are recognized lifestyle triggers that can exacerbate eczema symptoms, making mental-health management an essential part of a comprehensive health-and-wellness strategy.
- Environmental science plays a critical role in identifying triggers for eczema flare-ups, as common allergens such as dust mites, pet dander, pollen, and certain fabrics can cause irritation and inflammation.
- Severe eczema may require the intervention of medical professionals, including dermatologists, who can help individuals identify triggers and prescribe treatments that may be more effective based on their personas, skin-care needs, and specific medical-conditions.
- Science has not yet definitively linked specific foods as the causes of eczema, but individuals with eczema are encouraged to work with their doctors to explore dietary adjustments that may help manage symptoms, such as avoiding foods containing white flour, gluten, and nightshades.
- Individuals with eczema should take measures to protect themselves from the environment, such as using dust mite covers, limiting exposure to pollen, and applying fragrance-free sunscreen, to minimize the risk of flare-ups.
- Adhering to a health-and-wellness routine that focuses on skin care, mental health, and avoidance of known environmental triggers can help establish a healthy environment for individuals with eczema, reducing flare-ups and improving their overall quality of life.
