Influence of Physical Activity on Sleep Quality and Daytime Functioning in Individuals Suffering from Depression - A Literature Review
Abstract: Background: Depression is a multifactorial mental disorder frequently accompanied by sleep disturbances, including insomnia symptoms and poor subjective sleep quality. The relationship between sleep and depression is bidirectional, and persistent sleep problems often remain as residual symptoms despite treatment, contributing to impaired daytime functioning. Aim: This review aims to synthesize the current evidence regarding the effects of physical activity on subjective sleep quality and evaluate its potential impact on daytime cognitive and psychosocial functioning in individuals with depression. Material and methods: A structured literature review was conducted using PubMed, Scopus, Web of Science, and Google Scholar. Studies published between January 2016 and February 2026 were included. The review followed the PRISMA Statement for study identification and selection. Eligible studies involved adults with depression, examined physical activity or structured exercise, and assessed subjective sleep outcomes using validated instruments (PSQI, AIS, ISI). Both interventional and observational studies, as well as systematic reviews and meta-analyses, were included. Data were synthesized using a qualitative narrative approach. Results: Most included studies indicate that regular physical activity is associated with improvements in subjective sleep outcomes in individuals with depression. Reported effects include reductions in insomnia severity, improved perceived sleep quality, and increased sleep satisfaction. Moderate-intensity aerobic exercise was the intervention most consistently associated with beneficial outcomes. Improvements in sleep were frequently accompanied by reduced daytime fatigue, decreased sleepiness, and enhanced cognitive and psychosocial functioning. Conclusion: Physical activity appears to be an effective non-pharmacological adjunct for improving subjective sleep quality and daytime functioning in individuals with depression. By addressing persistent sleep-related symptoms, exercise may support broader functional recovery. Further high-quality studies are required to determine optimal exercise parameters and long-term effects.
