ABSTRACT: Emerging evidence indicates that childhood stressors, such as familial conflict, bullying, academic pressure, and traumatic events, can significantly worsen inflammatory skin conditions like atopic dermatitis (AD) and psoriasis. This review explores the underlying neuroimmune pathways that link stress to skin inflammation in children, focusing on the role of the hypothalamic-pituitary-adrenal (HPA) axis and stress-induced cytokine production. Studies have shown that chronic psychological stress leads to dysregulation of the HPA axis, resulting in elevated cortisol levels, which paradoxically impair skin barrier function and upregulate pro-inflammatory cytokines such as IL-6, TNF-α, and IL-1β. Specific stressors, such as bullying, have been associated with heightened immune responses, increasing inflammation in the skin. For example, research has demonstrated that children who experience social stressors show elevated levels of C-reactive protein (CRP) and other markers of systemic inflammation, which directly correlate with skin condition flare-ups. Furthermore, exposure to early life stress has been linked to long-term alterations in immune function, perpetuating chronic inflammation even in the absence of ongoing stress. Future research should focus on longitudinal studies assessing how the timing, duration, and type of stressors influence skin condition severity, alongside evaluating interventions like cognitive-behavioral therapy (CBT) and stress management techniques. By addressing these childhood stressors, there is potential to not only mitigate skin condition flares but also reduce the long-term health consequences of chronic inflammation leading to therapeutic strategies that emphasize mental health alongside traditional dermatological treatments.
