Overactive immune cells may release high levels of inflammatory substances that can injure organs and tissues.SARS-CoV-2 particles may become active again, causing symptoms to reappear.While we don’t know for sure what causes long COVID in general, research has provided some clues, per the National Institutes of Health (NIH): I would suspect that there’s some kind of a mechanism that occurs during the viral infection that’s having a prolonged effect on energy levels and things of that nature.” “As an example, if you look at mononucleosis - when we see people get mono, they can have fatigue for years. “We really don’t know a lot, but there has been some interesting historical research looking at the effects of other viruses,” says Dr. Overall, when it comes to the effects of long COVID and sleep, the exact link is still unclear. This emphasizes the need to characterize race-specific determinants and disparities in COVID-19 survivors, note the researchers. ![]() In fact, after adjusting for demographics, Black patients still had a three-fold higher odds of moderate-severe sleep disturbance. In the previously mentioned Sleep study, researchers found that patients with moderate to severe sleep disturbances were significantly more likely to be Black, to have fatigue and mood disorders, and to have been hospitalized for COVID-19, compared with patients with mild or no sleep disturbances. Changes in sleep phases can not only predispose you to health-related problems, but they can also increase stress levels by raising stress hormones. When you sleep, your body focuses on restorative functions related to immunity, the cardiovascular system, and metabolic functions. “These findings, especially after recovering from the infection, support the fact that COVID-19 may present with long-standing symptoms such as autonomic and neurologic disturbances,” note the study authors. They found that long COVID patients had altered sleep patterns characterized by less total sleep and less deep sleep compared to matched controls. That said, in a July 2022 study published in the Journal of Medical Internet Research, study authors analyzed 122 patients with a history of COVID-19 compared to those who had never had it. ![]() Many studies have pointed to both psychological and physical effects of COVID-19, but a large portion of sleep-related studies during the pandemic focused primarily on health care workers rather than the general population. This was true not only for people recovering from COVID-19, but also for those who felt the effects of fear and social isolation, according to a recent article in Neurology Today, the official publication of the American Academy of Neurology. Sleep neurologists reported more sleep disturbances and even the misuse of sleep medications during the COVID-19 pandemic. In what’s been termed “ COVID-somnia,” the pandemic negatively impacted sleep for many people. The Connection Between COVID-19 and Poor Sleep Here’s what to know about your sleep after COVID-19 and the steps you can take to move toward more restful nights. “When people are tired, pain hurts worse, which includes long COVID symptoms.” “When you are sleep-deprived, you actually feel more pain with the same stimulus,” says Dr. What’s more, if you live with an underlying condition and you’ve had COVID-19, it can be a recipe for sleepless nights - which could lead to even worse symptoms during the day. ![]() “If you did not have a sleep problem before COVID-19 but you do now, there’s a likelihood that you have a COVID-induced situation,” says Michael Breus, PhD, a diplomate for the American Board of Sleep Medicine and fellow for the American Academy of Sleep Medicine. In a May 2022 study published in the journal Sleep, researchers found that more than 40 percent of patients with a history of COVID-19 reported at least moderate sleep disturbances and nearly 70 percent reported at least moderate fatigue. To add to that, sleep disturbances and lingering fatigue are common in patients who recover from COVID-19. ![]() Next, you might wake up in the middle of the night because of pain ( painsomnia) - and that tiredness only amplifies your pain the next day. You may feel anxious about not being able to fall asleep, which then keeps you up even longer. When you’re living with an underlying chronic illness, lack of sleep can turn into a complex, vicious circle.
