There’s still much to learn about COVID-19 and its long-term effects on people who contract it.
For about 80% of people who have a mild reaction to Coronavirus, their symptoms go away in about two weeks. Others who have more serious cases need between three and six weeks to recover. One important area of study right now focuses on a third group known as COVID-19 long-haulers, people who experience new symptoms or prolonged symptoms more than three to four weeks after infection. COVID-19 long-haulers may need several months to recover, and even then, some symptoms and additional conditions like sleep disorders tend to pop up and linger along the way.
“Sleep disorders are one of the most common symptoms for patients who’ve had COVID-19,” says sleep medicine specialist Cinthya Pena Orbea, MD. “They report insomnia, fatigue, brain fog and sometimes we even see circadian rhythm disorders.”
Dr. Pena Orbea shares what we know so far about COVID-19’s connection with sleep disorders and what we can do to help alleviate some of those symptoms.
Is insomnia a symptom of COVID-19?
Coined “coronasomnia,” COVID-19-induced insomnia is often attributed to pandemic-related stress, anxiety, depression, and other mental health conditions.
“Long-hauler symptom is a new phase of the pandemic,” says Dr. Pena Orbea. “This is an area that we’re still studying.”
While we’ve identified more than 50 long-term effects of COVID-19, some studies suggest neuropsychiatric symptoms like post-traumatic stress disorder (PTSD), anxiety and insomnia can worsen over time. And according to Dr. Pena Orbea, people who’ve had mental health conditions before contracting the COVID-19 virus are at higher risk for developing worse anxiety and depression. This often results in someone developing a sleep disorder.
“The direct cause for long-hauler symptoms remains unknown,” says Dr. Pena Orbea. “Clinicians and researchers are exploring several possibilities that include having a persistent inflammatory state or an inadequate antibody response, and there’s another thought that there is an ongoing viral activity that’s causing organ damage.”
And while general fatigue is a symptom of COVID-19, sleep disorders like insomnia can set in up to a couple of weeks after first contracting the virus. So on the surface, the sleep disorder might not seem connected, but chances are, it’s a result of contracting the virus itself.
How long does it last?
There’s currently little data to determine exactly how long COVID-19-induced sleep disorders may last. According to Dr. Pena Orbea, it could last up to 12 months after beginning treatment.
What other sleep issues are associated with COVID-19?
Most commonly, Dr. Pena Orbea has seen circadian rhythm disorders arise as a result of COVID-19. In these cases, people have a delayed sleep cycle where they fall asleep much later into the evening or earlier in the morning. This delayed cycle extends into the following day, causing people to feel groggy, have chronic fatigue, or wake up later than they prefer.
What helps with COVID-19-related insomnia?
“Sleep is extremely important for the overall function of our bodies, including our metabolic systems and our immune systems,” explains Dr. Pena Orbea. “Since sleep is important for concentration and memory function, it will enhance how patients recover from the disease and impact their quality of life.”
To treat sleep disorders, including those caused by COVID-19, doctors often turn to cognitive behavioral therapy, light therapy, melatonin, or a mixture of methods to help correct your sleep schedule and improve your sleep hygiene.
When to see your doctor
This can be a difficult question for some people because it’s easy to assume your loss of sleep is a result of a long day of work, moderate stress, or a small, one-time problem. But Dr. Pena Orbea suggests any symptoms related to sleeplessness are a cause to get a checkup.
“It’s important to see your doctor whenever you’re developing a new symptom because it could be a sign or symptom of another disease and this is difficult to discern,” says Dr. Pena Orbea. “If you’re experiencing any symptoms that are interfering with your daily life, that’s when you need to call your doctor.”
