What causes eczema? Environmental factors are the most important

The most important cause of eczema is environmental factors, followed by microbial infection and dietary factors. If eczema occurs, you should take medication in time, avoid scratching with your hands, eat a light diet, and maintain a happy mood.

1. Environmental factors (30%):

Many studies have confirmed that environmental factors are one of the important reasons for the increase in the prevalence of eczema. The environment includes group environment and individual environment. The group environmental pathogenic factors of humans refer to a large range of outdoor air, water, soil, radiation sources, large areas of allergenic pollen vegetation, large areas of airborne allergenic bacteria, etc. The individual microenvironment refers to the individual's living environment. Since people spend about 2/3 of their lives indoors, the individual microenvironment has a closer impact on eczema. The impact of environmental factors mainly refers to the increasingly increasing and complex environmental allergens, including:

1. Environmental allergens in modern clothing such as artificial fabrics, artificial leather products, clothing-related printing and dyeing agents, bleaching agents, brighteners, mothproofing agents, mildewproofing agents, and stiffening agents.

2. Artificial food, convenience food, off-season food, fertilizers, pesticides, artificial feed, feed additives used in food production, preservatives, mineral oxidants, spices, pigments, ripening agents, thickeners, etc. used in food processing, and modern dietary environmental allergens.

3. Artificial building components, chemical coatings, plastic products, rubber products, artificial fibers, adhesives, waterproofing agents, electromagnetic radiation generated by household and office electronic equipment, room cleaners, pesticides are functional environmental allergens in modern living.

4. Environmental allergens of modern transportation, such as gases produced by the combustion of chemical fuels, materials used to make cars, ships, and airplanes, asphalt pavements of roads, pollen from green plants along the road, etc.

5. Environmental allergens in modern occupations, such as all enzyme preparations used to make detergents in detergent factories, toluene diisocyanate in plastic factories, latex in rubber factories, antibiotics and other chemical raw materials in pharmaceutical factories.

6. Certain environmental allergens related to modern lifestyles, such as the use of cosmetics, cats, parrots, etc. When the human body lives under the influence of such adverse environmental factors for a long time, it can lead to immune dysfunction and ultimately cause allergic reactions to the environment, thus causing eczema.

2. Infection factors (25%):

Some eczemas are related to microbial infections, including Staphylococcus aureus, Malassezia, aerogenes such as Alternaria, Cladosporium, Penicillium, Aspergillus fumigatus, Fusarium, Penicillium chrysogenum, Aspergillus niger and Rhizopus niger.

3. Dietary factors (15%):

There are many kinds of food for human beings, which can be generally divided into plants, animals and minerals. In modern times, some chemically synthesized foods such as saccharin, acetic acid, citric acid, flavors, synthetic dyes, etc. are often used in food. These foods can cause food allergies, thus leading to the occurrence of eczema. According to literature reports, foods that are prone to allergic reactions in my country are mainly protein-rich foods, such as milk, eggs, etc.

Seafood, such as shallots, garlic, onions, lamb, etc.; foods with special irritants, such as chili peppers, wine, mustard, pepper, ginger, etc.; certain raw foods, such as raw onions, raw garlic, raw tomatoes, certain raw shell fruits, such as almonds, chestnuts, walnuts, and certain fruits, such as peaches, grapes, lychees, bananas, pineapples, longans, mangoes, strawberries, etc.;
