Psoriasis is an autoimmune skin disorder that causes scaling, inflammation, and redness of the skin. In extreme cases, it may cause pus-filled blisters, extreme pain, and constant discomfort as well. Determining the exact cause of the condition is extremely important to provide proper medical care. Additionally, the remedial methods may vary greatly based on the triggers and causes of psoriasis. Here, the article will consider what are the main causes of psoriasis.

What are the main causes of psoriasis?

Currently, research has not been able to determine the exact causes of the medical condition. However, the patient’s genetics and immune system are certainly significant determinants of psoriasis. Our genetic coding is complex. Consequently, people with no familial history of the condition can still end up developing psoriasis. Additionally, triggering events may damage the immune system resulting in the onset of different conditions. 

What are psoriasis triggers?

The triggers of the condition vary greatly between people. Some triggers may aggravate the condition in some people while not affect others. However, some common triggers are as follows:

  • Stress is called the silent killer for a reason: it aggravates most other illnesses and conditions a person is facing, including psoriasis. It is the most common trigger for psoriasis. However, psoriasis flare may lead to stress as well. As such, both the conditions have an infinite loop, with one causing the other. Reducing stress through relaxation techniques can help soothe the symptoms of psoriasis as well.
  • A skin injury can cause the onset of psoriasis. The Koebner phenomenon applies, where psoriasis flare can be triggered by bug bites, scratches, and sunburns. In many cases, vaccinations to the skin can also trigger psoriasis.
  • A weakened immune system is a ripe ground for the development of psoriasis. Thus, illnesses affecting the immune system may result in psoriasis as well. Patches of red and inflamed skin can follow ear infections, tonsillitis, and respiratory infection. Similarly, strep or throat infection can lead to guttate psoriasis in children.
  • Weather conditions are important as well. Cold weather with humidity and less sunlight can lead to the development of psoriasis. Additionally, artificially heated and drier indoor air may trigger psoriasis as well. Staying in an area with warm weather and sunlight can reduce the effects of psoriasis.
  • Some people with allergies may develop psoriasis as well.
  • Infrequently, psoriasis may be caused by food reactions and environmental factors as well.

Psoriasis triggers can certainly vary from person to person. As such, the unique set of triggers for any patient can be listed and monitored to better understand when the patient may need medical assistance. Tracking the changes in the patient’s condition can help with the management of their disease.

What causes scalp psoriasis?

Scalp psoriasis is not contagious. Instead, it, too, is related directly to the immune system of the person. The skin cells in your scalp start to develop and come to the surface quickly. However, they do not fall off at the same speed, resulting in cell buildup and scalp inflammation. However, genetically triggered scallop psoriasis is common. People with a familial history of scalp psoriasis may develop the condition as well.


Different common triggers affect people who have psoriasis. The main causes revolve around immune system disorders and genetic issues. However, many triggers as simple as an insect bite may trigger the development of psoriasis. The crucial factor is to determine your own unique set of triggers so that you can receive medical assistance in time before the next onset. I hope the article helped you in managing your psoriasis condition.
