Experts have also noted another symptom of long COVID prevalent in most people, which is sleep issues or insomnia.
“Sleep disorders are one of the most common symptoms for patients who’ve had COVID-19,” says Cinthya Pena Orbea, sleep medicine specialist at Cleveland Clinic.
Talking to Nexstar Media Group, she says, “They report insomnia, fatigue, brain fog and sometimes we even see circadian rhythm disorders.”
The circadian rhythm is an internal process that follows a 24-hour sleep-wake cycle. That said, circadian rhythm sleep disorder occurs when the body's internal clock goes haywire and does not match the immediate environment. This includes difficulty in falling asleep, waking up when you should be asleep or waking up too early and being unable to fall back to sleep.
