Abstract: Caffeine is regularly consumed by individuals who engage in physical activity due to its ergogenic effects, which include increased energy and decreased perception of exertion; however, excessive consumption can impair sleep quality, potentially leading to deficits in muscle recovery and physical performance. The present study analyzed the relationship between caffeine use and sleep quality in physically active individuals, considering its possible effects on rest and muscle recovery. This is a narrative review of the literature, whose objective was to gather, analyze, and interpret relevant scientific studies addressing the relationship between caffeine consumption, sleep quality, and athletic performance. The studies were selected through searches in the PubMed, SciELO, Google Scholar, and ScienceDirect databases, conducted between February and November 2025. The results allowed us to identify and organize scientific evidence about the effects of caffeine consumption on the sleep quality of people who practice physical activities, as well as to understand how variables such as dose, time of intake, and individual sensitivity influence this relationship.The analysis of the studies gathered showed relevant ergogenic effects of caffeine, especially in weight training, but also in other sports. However, it was observed that inappropriate consumption, especially close to nighttime, can compromise sleep quality, affecting muscle recovery, physical performance, and metabolic balance.
