Background:
Analyze how the COVID-19 (SARS-CoV-2) pandemic and its social restriction measures affect sleep quality and the immunological system.
Methods:
An integrative bibliographical review was carried out using scientific articles from the last five years, from the PUBMED databases, with the descriptors: Sleep; Quarantine; COVID-19; Immunity; Mental Health. Besides the books "Oxford textbook of sleep disorders", "Cellular and molecular immunology", and "Treaty of Infectology".
Results:
Sleep affects immunity. This happens through the regulation of immunological markers and their cells. Therefore, the COVID-19 pandemic can promote sleep disturbances and harm the immune system function.
Conclusion:
Sleep exercises a direct influence on immunity maintenance and immunological response. Circadian rhythm alterations, associated with the psychological problems imposed by the COVID-19 pandemic compromise the quality of sleep and, for that reason, the immune system.
