This study aims to analyze the effects of military submarine activities on sleep quality. A systematic review based on a search carried out on the PubMed, Cochrane, Web of Science, LILACS, SCOPUS, and Embase databases in October 2023 (updated in July 2025) following the PRISMA 2020 guidelines. The descriptors “submariners” and “sleep” (found on MeSH and DeCS) and their synonyms were used. Studies that sampled submariners were included, the results of which indicated sleep quality, medical and laboratory tests, and self-reported questionnaires. In total, 198 articles were retrieved from the databases, of these, six studies were included in this review. Several sleep assessment instruments were found, such as questionnaires, laboratory analyses of salivary melatonin and cortisol, and wrist actigraphy data. Submarine activities affect sailors’ total sleep time and self-reported sleep quality. The operational shift work on submarines negatively affects sailors’ quality of sleep.
