Silent Emotional Exhaustion in Childhood: Relationships Between Stress, Sleep, and Digital Overload in Pediatric Mental Health

Abstract

Introduction: Emotional disturbances during childhood can present with non-specific manifestations, frequently expressed through irritability, sleep alterations, difficulty concentrating, reduced school performance, and behavioral changes. Concurrently, children are increasingly exposed to digital stimuli, sleep routine disruptions, and various sources of psychosocial stress. The interaction between these factors can produce subclinical manifestations of emotional distress that often remain unrecognized until more evident functional impairment occurs.

Objective: To analyze the evidence regarding the interaction between psychological stress, sleep, and excessive digital media exposure in children's mental health, with an emphasis on early manifestations of emotional exhaustion and psychological vulnerability.

Methodology: This is an integrative literature review conducted across the PubMed, Scopus, and Virtual Health Library databases. The descriptors used were "Child Mental Health", "Psychological Stress", "Emotional Exhaustion", "Sleep", "Screen Time", "Digital Media", "Anxiety", and "Depression", combined using the Boolean operators AND and OR. Studies published between 2020 and 2026, in English, Portuguese, or Spanish, involving children and adolescents and addressing the relationships among stress, sleep, digital exposure, and mental health outcomes were included. Case reports, editorials, letters to the editor, and studies without a direct relationship to the pediatric population were excluded.

Results: The evidence suggests that insufficient or poor-quality sleep, greater exposure to digital media, and psychosocial stress may present independent and interrelated associations with symptoms of anxiety, depression, irritability, attention difficulties, and behavioral alterations. Sleep deprivation can intensify emotional disturbances and reduce coping capacity in the face of stressful situations, while prolonged digital exposure can interfere with both sleep routines, physical activity, and social interactions. The simultaneous presence of these factors may represent a pattern of greater psychological vulnerability, especially when accompanied by persistent changes in school, family, or social functioning.

Conclusions: Childhood emotional exhaustion may manifest initially through subtle alterations in sleep, behavior, attention, and daily performance, prior to the onset of clearly defined psychiatric conditions. An integrated understanding of the relationship between stress, sleep, and digital overload can enhance the early recognition of vulnerable children and promote preventive strategies in pediatric mental health.
