IMPACT OF CHRONIC INSOMNIA ON QUALITY OF LIFE A NARRATIVE REVIEW

Abstract

Chronic insomnia is a widespread sleep disorder characterized by persistent difficulties
in initiating or maintaining sleep, which significantly impairs health burden in various aspects
of an individual's quality of life (QoL). Insomnia has profound effects on physical,
psychological, occupational, and social domains.
This narrative review aims to explore and synthesize existing literature on the
multidimensional impact of chronic insomnia on quality of life which highlighting the extents
of impairment and the importance of early recognition and comprehensive management.
Relevant peer-reviewed studies, clinical guidelines, and epidemiological data were
reviewed to assess the relationship between chronic insomnia and QoL parameters using
certain tools such as the SF-36 and Quality of Life Scale for Insomnia (QOL-I).
Chronic insomnia is associated with increased risks of cardiovascular disease,
metabolic dysfunction, mental health disorders (particularly depression and anxiety), cognitive
impairments, and reduced work and social performance. Individuals with insomnia consistently
report significantly lower scores on QoL assessments compared to healthy sleepers. Evidence
supports the effectiveness of cognitive behavioral therapy for insomnia (CBT-I) in improving
sleep quality and restoring overall well-being.
