Impacts of Coronavirus Disease 2019 Pandemic on Sleep Pattern

Abstract

The ongoing coronavirus disease 2019 (COVID-19) pandemic is the third global crisis after two epidemics of severe acute respiratory syndromes. It has affected general public besides health care systems and governments. Confinements and lock downs have changed waking up time and going to bed time, ultimately affecting circadian clocks that can disturb sleep quality which can lead to anxiety, stress, and depression. This puts the most susceptible group -young adults and females- at risk of psychological disorders and even inflammatory events. Several kinds of sleep disorders due to COVID-19 including insomnia, sleep apnea, sleepiness during daytime, post-traumatic-like sleep dysfunction, abnormal dreams, and restless legs syndrome have been reported. As sleep deprivation can alter circadian clock and weaken immunity which makes human more susceptible to pulmonary inflammatory process of COVID-19 and even enhance its manifestations, it should be considered as an urgent complication that needs to be treated. Furthermore, longstanding effects of sleep disturbances during COVID-19 pandemic need to be elucidated.
