Although more than 6·8 million deaths have been attributed to COVID-19 worldwide, survivors of COVID-19 can be affected in numerous ways across multiple organ systems. The entity of long COVID has been controversial and remains poorly defined, but it is now clear that COVID-19 has a long-term impact in many individuals. The complaints among COVID-19 survivors are myriad but include fatigue, difficulty concentrating, sleep disturbance, anxiety, and dyspnoea. However, the causes of these complaints are unclear, with some studies suggesting a dissociation of objective abnormalities from subjective complaints.

Sleep disorders are also exceedingly common.
