2. Why do you get eczema and urticaria?
The causes of eczema and urticaria are complex and are usually related to the following factors:
1. Genetic factors
People who have a family history of allergies or skin problems are more likely to develop eczema or hives. Research shows that if one parent has allergic diseases, the risk of children suffering from allergies increases by 30%-50%.
2. Environmental factors
Air pollution, climate change (such as dryness or humidity), exposure to chemicals (such as detergents, cosmetics), etc. may induce skin problems.
3. Dietary factors
Certain foods (such as seafood, nuts, dairy products) can trigger allergic reactions that can lead to hives. People with eczema may also have symptoms aggravated by improper diet.
4. Psychological stress
Chronic stress and anxiety can weaken the immune system and increase the risk of eczema and hives.
5. Immune system abnormalities
Autoimmune diseases or immune disorders may lead to chronic urticaria or refractory eczema.
