The most common type of eczema is called atopic dermatitis, and it's a chronic disease that makes sufferers very itchy and sometimes causes infections and other complications. No one is sure what causes eczema, but there is probably a hereditary aspect involved. Outside factors that may contribute to eczema flare-ups include irritants found in industrial chemicals, skin care products, synthetic fibers and detergents; allergens that come from food, pollen, pets and dust; weather changes; dry skin; sweating and stress. People who have eczema frequently have a lot of extra staph bacteria on their skin [source: Boyles]. That staph might be a trigger to an eczema outbreak, or it might make infections more likely in the event of an outbreak. In any case, the exaggerated staph level isn't desirable. Antibiotics aren't great remedies, because eventually bacteria develop resistance to them. But when eczema sufferers take a bath in warm water with about a half cup of bleach in it, it kills off the bacteria that can pose a danger.
