Eczema, or atopic dermatitis, is a chronic, often flare-up skin condition that causes frequent, itchy, red, scaly rashes. Its causes are likely to be complex, with genetic predisposition and environmental factors playing a combined role.
In the case of eczema, genetic predisposition means that if someone has eczema in their family, they are more likely to develop eczema.
With a genetic predisposition, the skin is less resistant to external influences and more prone to water loss and irritation. Genetic predispositions to eczema include genes responsible for skin hydration, regulating inflammation and maintaining the skin’s defences.
The environmental factors of eczema
These include those factors that adversely affect the development and severity of the disease through their effects on the skin and the body.
Examples of environmental factors include stress, household chemicals, clothing materials, too much bathing and too much washing, and excessive dryness or humidity in the home.
Stress is an environmental factor that can adversely affect eczema symptoms. Stress can promote inflammatory processes and make it difficult for the skin condition to improve.
Household chemicals, such as detergents and fabric softeners, can have a negative impact on eczema symptoms. Such chemicals can irritate the skin and make it difficult for the skin condition to improve. The use of household chemicals should be kept to a minimum and it is recommended to use products that are certified hypoallergenic.
Clothing materials, such as synthetics, can also negatively affect eczema symptoms. Synthetic substances can irritate the skin and make it difficult for the skin condition to improve. It is recommended to wear clothing that is made of natural materials and that is breathable.
