[Sleep disorders as a result of the COVID-19 pandemic].

Respiratory complications from COVID-19 can lead to death. For this reason, public health measures to curb the spread of the disease such as quarantine and other confinement strategies have been proposed in several countries, resulting in mental health and sleep disorders. We carried out a narrative review to systematize the most significant findings regarding insomnia in hospitalized patients with COVID-19, and in healthy persons who have been under confinement as a preventive measure. COVID-19-related conditions have caused insomnia in patients, which can alter the immune system and have a negative effect on health. For healthy people in quarantine, lifestyle changes, fear of becoming infected, young age, female gender, history of mental illness and reduced ability to cope with stress appear to be risk factors for insomnia. As well as the implementation of epidemiological and preventive measures, sleep hygiene should be promoted as a comprehensive coping strategy against the COVID-19 pandemic.
