What causes psoriasis to occur.

There is no single cause associated with the manifestation of psoriasis, some of the main factors that can trigger the typical rashes are:

- Stress and all circumstances that have a negative impact on a person's psyche;

- all types of trauma to the skin, such as scratching, burns, cuts, accidental blows;

- lithium-based medicines and beta-blockers, antimalarials, corticosteroids;

- throat infections caused by the beta-hemolytic streptococcus bacterium;

- altered metabolism, but also a diet low in calcium;

- cigarette smoking and excessive alcohol consumption.

Other conditions that can aggravate the frequency and severity of skin flare-ups are:

- exposure to cold temperatures that dehydrate the skin and make it dry and more sensitive;

- washing with hot or excessively cold water;

- using aggressive detergents and even more so prolonged immersion in water;

- wearing tight clothing and irritating fabrics;

- rubbing the lesions with sponges, gloves, abrasive scrubs or vigorously drying the skin.
