Psoriasis is a chronic, immune-mediated inflammatory skin disorder characterized by erythematous, scaly plaques that significantly affect patients’ physical and

psychological well-being. The disease has a multifactorial etiology involving genetic predisposition, environmental triggers, and immune system dysregulation (4,7). In recent years, increasing attention has been given to the role of psychological factors, particularly stress, in the onset and exacerbation of psoriasis.

Psychological stress is recognized as an important trigger in psoriasis, with a substantial proportion of patients reporting stress as a precipitating or aggravating factor for disease flare-ups (1,2). Systematic reviews and meta-analyses have demonstrated a strong association between stress and psoriasis severity, highlighting the importance of psychological factors in disease progression (1). Early experimental and prospective studies also provided evidence that stress can influence the clinical course of psoriasis (3).

The underlying mechanisms linking stress and psoriasis are complex and involve interactions between the nervous, endocrine, and immune systems. Stress has been shown to alter immune responses, leading to increased production of pro-inflammatory cytokines, which play a key role in the pathogenesis of psoriasis (8,9). Furthermore, psychological stress can impair skin barrier function and delay healing processes, thereby contributing to disease severity.

In addition to biological mechanisms, psychological stress also affects patients’ coping behaviors and quality of life. Studies have reported that patients with psoriasis often experience higher levels of anxiety, depression, and emotional distress, which may further exacerbate the condition (5,6). Moreover, the visible nature of psoriasis lesions can lead to social stigma and psychological burden, creating a vicious cycle where stress worsens psoriasis and psoriasis increases stress levels (10).

Despite growing evidence supporting the relationship between stress and psoriasis, the extent to which psychological stress influences disease severity remains variable across studies. Therefore, this study aims to assess the impact of psychological stress on psoriasis severity and to provide further insight into the role of stress as a modifiable factor in the management of psoriasis.

Study Design and Setting This was a cross-sectional observational study conducted to assess the impact of psychological stress on psoriasis severity. The study was carried out Conducted at The Department Of dermatology and Community Medicine & Medical Education of MBBS Medical College, Mirpur AJK From 1st August 2024 To 30th Sep 2025. Study Population The study included patients diagnosed with psoriasis attending dermatology outpatient departments. A total of 300 participants were enrolled in the study, including both males and females aged 18–60 years.A non-probability convenience sampling technique was used to recruit participants who fulfilled the inclusion criteria during the study period. Inclusion Criteria • Clinically diagnosed cases of psoriasis • Age 18 years and above • Both genders • Patients willing to participate and provide informed consent Exclusion Criteria • Patients with other chronic skin diseases • Individuals with severe psychiatric disorders unrelated to stress • Patients on long-term immunosuppressive therapy unrelated to psoriasis • Pregnant or lactating women Data Collection Procedure Data were collected using a structured and pre-tested questionnaire, which included: 1. Sociodemographic Information ;Age, gender, education level, occupation, and marital status 2. Assessment of Psychological Stress: Psychological stress was evaluated using a standardized stress assessment tool (e.g., Perceived Stress Scale - PSS). Participants were categorized into: o Low stress o Moderate stress o High stress 3. Assessment of Psoriasis Severity: Psoriasis severity was measured using the Psoriasis Area and Severity Index (PASI) score and classified as: o Mild o Moderate o Severe

A total of 300 psoriasis patients were included in the study. The mean age was 38.6 ± 11.4 years. There were 176 (58.7%) males and 124 (41.3%) females. Most participants belonged to the 31–45 years age group (46%), followed by 18–30 years (30%) and 46–60 years (24%).  Patients with high stress levels had significantly more severe psoriasis.  Low stress was associated mostly with mild disease. A strong statistically significant relationship was observed between stress and psoriasis severity (p < 0.001).

The present study evaluated the impact of psychological stress on psoriasis severity and demonstrated a significant association between higher stress levels and increased disease severity. These findings are consistent with existing literature, which highlights stress as an important factor influencing the course and exacerbation of psoriasis.

Psychological stress is known to have profound effects on the immune system, which plays a central role in the pathogenesis of psoriasis. Stress can dysregulate immune responses by altering cytokine production and activating inflammatory pathways, thereby contributing to disease exacerbation (11). Furthermore, stressful life events have been identified as triggers for both the onset and worsening of psoriasis, supporting the role of stress as a precipitating factor (12,13).

In addition to biological mechanisms, psychological stress significantly affects patients’ quality of life and mental health. Studies have reported that individuals with psoriasis often experience higher levels of stress, anxiety, and depression, which may further aggravate the disease (14,15). This bidirectional relationship creates a vicious cycle in which stress worsens psoriasis, and the visible and chronic nature of psoriasis increases psychological distress.

Moreover, stress-related changes in behavior and coping strategies can influence disease severity. Poor coping mechanisms, such as avoidance or maladaptive stress responses, have been associated with increased psoriasis severity and more frequent flare-ups (20). Clinical observations also indicate that stress can act as a trigger for psoriasis flares, leading to worsening of symptoms during periods of emotional or psychological strain (17).

The role of neuroendocrine and immunological pathways in linking stress and psoriasis has been widely recognized. Stress activates the hypothalamic–pituitary–adrenal (HPA) axis and the sympathetic nervous system, which in turn modulate immune function and inflammatory responses in the skin (16,18). Recent evidence also suggests that stress-induced immune dysregulation contributes to the chronic inflammatory state observed in psoriasis (19).

Overall, the findings of this study are in agreement with previous research, confirming that psychological stress is a significant factor influencing psoriasis severity. The relationship is complex and involves multiple biological and psychological pathways, emphasizing the need for a holistic approach in psoriasis management.

The present study concludes that psychological stress has a significant impact on the severity of psoriasis. Increased stress levels are associated with worsening of symptoms and more frequent disease flare-ups. The findings highlight that psoriasis is not only a dermatological condition but also closely linked with psychological factors. Therefore, effective management of psoriasis should include stress reduction strategies along with standard medical treatment to improve disease control and patient quality of life.
