What causes Psoriasis?
Psoriasis is a multifactorial genetic disease. About 30% of people with psoriasis have a family history of the condition, and certain genes have been linked to psoriasis. However, the condition will only appear if it is triggered by an environmental factor. Triggers may include stressful life events, infection with certain viruses and bacteria, skin injury, or reactions to certain medications.
The cause of psoriasis is not certain, but it is thought to be related to an immune system problem. More specifically, the altered life cycle of one key cell in the body - a type of white blood cell called a T lymphocyte. These T cells normally travel throughout the body detecting and fighting off foreign substances, such as viruses or bacteria. However, in individuals with psoriasis, the T cells attack healthy skin cells by mistake. As a result, cells build up rapidly on the skin’s surface. These form a thick, scaly layer which can be itchy or painful.
Is psoriasis contagious?

What is the role of climate and sunlight?
