What causes eczema?
The exact cause of eczema is unknown, but it's thought to be linked to an overactive response by the body's immune system to an irritant. It is this response that causes the symptoms of the disease. In addition, eczema is commonly found in families with a history of other allergies or asthma.
Eczema causes and triggers Some people may suffer "flare-ups" of the itchy rash in response to certain substances or conditions. For some, coming into contact with rough or coarse materials may cause the skin to become itchy. For others, feeling too hot or too cold, exposure to certain household products like soap or detergent, or coming into contact with animal dander may cause an outbreak. Upper respiratory infections or colds may also be triggers. Stress may cause the condition to worsen. The condition is not contagious and can't be spread from person to person. Other eczema causes or triggers may be:
- Changes in temperature or humidity
- Chemical irritants, such as pesticides, paint strippers, alcohol, astringents, perfumes, harsh soaps, detergents, and household cleaners
- Physical irritants, such as clothes made of rough or scratchy fabrics, like wool
- Allergies (to dust, pollen, mold, animal dander, etc.)
- Intense emotion or stress
- Infections of any kind
People with eczema should work closely with their healthcare providers to determine what triggers their eczema flare-ups. They can then take steps to avoid these triggers and minimize the onset of a skin rash.
