Recent research suggests that a New Study Shows Insomnia More Common in COVID-19 survivors, affecting a significant portion of patients regardless of illness severity.
Understanding the Link Between COVID-19 and Sleep
Evidence regarding the prevalence of sleep disorders after a coronavirus infection varies across different research groups. One analysis of approximately 236,000 patients aged 10 and older found that about 34% of survivors experienced at least one psychiatric or neurological issue. In this specific group, insomnia affected 5.4% of all patients. The data indicated that the risk rose as the illness became more severe:
- Non-hospitalized patients: 5.2%
- Hospitalized patients: 6%
- Those in the Intensive-Therapy-Unit: 7.5%
- Patients with encephalopathy: 10%
Conversely, a different study involving over 1,000 adults in Vietnam focused on those who were not hospitalized and had no previous sleep issues. This research found a much higher rate, with 76% of participants reporting insomnia within six months of their infection. About 25% of these individuals experienced severe symptoms.
Risk Factors and COVID-19 Symptoms
Beyond the primary infection, certain factors may increase the likelihood of developing sleep problems. People with metabolic disorders, heart disease, or higher education levels showed a greater tendency to struggle with sleep.
Mental health also plays a significant role. There is a bidirectional link where anxiety and depression can trigger sleep disturbances, and poor sleep can further degrade mental health. Many survivors reported a decline in sleep quality, shorter durations of rest, and more frequent nighttime awakenings. These issues often manifest as daytime fatigue or difficulty focusing, which are common post-viral covid-19 symptoms.
Why Does This Happen?
Scientists believe several mechanisms could cause these neurological impacts:
- The virus may invade the central nervous system.
- The body’s immune response might put stress on the nervous system.
- Blood clotting issues could contribute to the damage.
FAQ
What is post-COVID insomnia?
It is a sleep disorder where survivors of the virus have trouble falling asleep or staying asleep, often leading to daytime sleepiness.
Who is most likely to develop sleep issues after COVID-19?
Those with pre-existing chronic conditions like heart disease, individuals with depression or anxiety, and patients who required intensive hospital care are at higher risk.
How common is this condition compared to the general public?
While the general population typically sees insomnia rates between 10% and 20%, some studies of non-hospitalized survivors have seen rates as high as 76%.
When to See a Doctor

- Severe difficulty falling or staying asleep that interferes with daily functioning.
