The environment

If your genes make you more likely to develop atopic eczema, the condition will develop after you are exposed to certain environmental factors, such as allergens.
Allergens are substances that can cause the body to react abnormally. This is known as an allergic reaction. Some of the most common allergens that can cause atopic eczema include:

  • house dust mites
  • pet fur
  • pollen

Atopic eczema can sometimes be caused by food allergens, especially before the age of one. Foods that typically cause allergic reactions include:

  • cows' milk
  • eggs
  • nuts
  • soya
  • wheat

Some studies of children and young people with atopic eczema found that one-third to nearly two-thirds also had a food allergy. Having a food allergy increases the likelihood of your atopic eczema being severe.

Allergies do not always play a role. There are many other things likely to bring out eczema, including:  

  • cold weather
  • dampness
  • harsh soaps
  • washing too much
  • rough clothing
