Can people with psoriasis drink coffee?

Psoriasis vulgaris—commonly referred to as “plaque psoriasis”—is a chronic, immune-mediated, recurrent skin disorder. In general, patients with psoriasis vulgaris are advised to avoid coffee consumption. This is because coffee contains caffeine, which exerts a stimulatory effect on the body.

Caffeine in coffee stimulates the central nervous system and may disrupt the patient’s circadian rhythm. Poor sleep quality resulting from such disruption can compromise immune function, thereby impeding recovery from psoriasis vulgaris.

Coffee offers no therapeutic benefit for psoriasis vulgaris; rather, it may adversely affect individuals who are sensitive to caffeine—disrupting their sleep-wake cycle and potentially lowering immunity. Therefore, coffee consumption is not recommended during active disease.

Numerous factors can trigger psoriasis vulgaris, including infections, sunburn, and psychological stress. Management typically involves pharmacotherapy combined with lifestyle modifications, alongside efforts to enhance overall immune function.

Additionally, patients with psoriasis vulgaris should avoid consuming highly stimulating or spicy foods—such as seafood, coffee, and lamb—and instead opt for nutrient-rich foods high in vitamins and protein, including eggs and carrots. It is crucial to refrain from scratching affected areas or washing them with hot water, as these habits may exacerbate the condition.

Patients diagnosed with psoriasis vulgaris are strongly encouraged to seek care at a specialized medical institution and undergo treatment under the guidance of a qualified physician.
