Meditation for Insomnia: A Comprehensive Review of Mechanisms, Efficacy, and Clinical Applications

Insomnia, a common sleep disorder involving difficulty falling or staying asleep, harms physical and mental health. Pharmacological treatments carry risks of side effects and dependency. Meditation, an ancient mind-body practice, offers a promising non-pharmacological alternative. This review synthesizes evidence from randomized controlled trials, systematic reviews, and meta-analyses. Meditation alleviates insomnia by reducing hyperarousal, modulating stress responses, and enhancing emotional regulation. Mindfulness-based interventions, including Mindfulness-Based Stress Reduction and Mindfulness-Based Therapy for Insomnia, significantly improve sleep onset latency, wake after sleep onset, and insomnia severity index scores. Yoga nidra and mantra meditation also reduce sleep disturbances. Older adults, patients with chronic illnesses, and those with stress-related insomnia benefit notably. Meditation is effective and safe, but further research on long-term efficacy and mechanisms is needed.

Abstract

Insomnia is a prevalent sleep disorder characterised by difficulty initiating or maintaining sleep, which significantly impacts both physical and mental health. Pharmacological treatments, while effective, pose risks of side effects and dependency. Meditation, a mind-body practice with ancient roots, has emerged as a promising, non-pharmacological intervention for managing insomnia.This review aims to synthesise existing evidence on the role of meditation in alleviating insomnia, exploring its mechanisms, effectiveness across populations, and potential as a complementary therapy.A comprehensive analysis of the research literature was conducted, focusing on randomised controlled trials (RCTs), systematic reviews, and meta-analyses that examined meditation interventions for insomnia. Mechanisms of action, population-specific findings, and practical implications were also explored. Meditation alleviates insomnia through mechanisms such as reducing hyperarousal, modulating stress-related physiological responses, and enhancing emotional regulation. Mindfulness-based interventions (MBIs), including Mindfulness-Based Stress Reduction (MBSR) and Mindfulness-Based Therapy for Insomnia (MBTI), significantly improve subjective and objective sleep parameters, such as sleep onset latency (SOL), wake after sleep onset (WASO), and insomnia severity index (ISI). Specific approaches like yoga nidra and mantra meditation have demonstrated efficacy in reducing sleep disturbances. Older adults, patients with chronic illnesses, and individuals with stress-related insomnia benefit particularly from meditation interventions.Meditation is an effective, safe, and holistic approach to managing insomnia, addressing both symptoms and underlying causes such as stress and hyperarousal. While robust evidence supports its use, further research is required to explore its long-term efficacy, neurophysiological mechanisms, and comparative effectiveness with other treatments.
