Do Sleep Disorders and Western Diet Influence Psoriasis? A Scoping Review

Nutrients. 2022 Oct 16;14(20):4324. doi: 10.3390/nu14204324.


Western diet may trigger sleep disorders and vice versa, but their single and mutual effects on systemic inflammatory diseases (i.e., psoriasis) are far from being fully elucidated. At the same time, psoriatic patients display a great burden of sleep disorders and dysmetabolisms related to an unhealthy lifestyle (i.e., diet). These patients are also affected by a chronic disorder deeply modulated by environmental factors (i.e., sleep and diet) capable to influence drug-response and disease progression. Thus, we aimed to summarize the evidence in the literature that may highlight a potential link among psoriasis-diet-sleep in order to further promote a multidisciplinary approach to psoriatic patients in the scientific community.
