Relationship between Physical Exercise and Sleep Quality in Adults: A Literature Review

Abstract

This study reviews scientific evidence on how physical exercise affects sleep quality in adults, as sleep disorders represent problems that impact individual health. Various studies have been reviewed, which indicate that physical activity can influence sleep regulation. The objective was to systematically analyze scientific evidence on the influence of physical exercise on sleep quality in adults. The methodology included a systematic review of scientific articles in indexed scientific databases, including SciELO, Dialnet, and Web of Science. The PRISMA method was used to systematize the information for the selection, screening, and inclusion of studies. Fourteen studies that met the established eligibility criteria were selected for inclusion. According to the results, most studies report positive associations between regular physical exercise and improvements in sleep quality, such as efficiency, duration, and latency, although there is heterogeneity in the designs and populations analyzed. In conclusion, there is evidence that physical exercise is a potentially beneficial strategy for improving sleep quality in adults.
