Scientists do not know what causes some people to have an overabundance of reactive inflammatory cells. When something triggers a reaction, these cells do not turn off, as they should. Common treatment of atopic dermatitis is to prevent the trigger factors that turn on reactive inflammatory cells. People with atopic dermatitis have a hard time keeping their skin moist, thus it becomes dry, scaly, rough, and tight. These are substances outside the body, which cause burning, itching, redness, bumps, etc.
Stress is caused by a variety of situations and is characterized by red flushing and itching.
Sweating causes prickly heat and commonly occurs during exercise, exposure to humidity, heat, etc. Common allergens like dust mites, pollen, pet dander, and food can trigger atopic dermatitis. What skin care products do best is lock in moisture after a bath. For further information regarding infant skin disorders contact the American Academy of Pediatrics or the National Eczema Association.
