Insomnia in Long Covid

Understanding and Managing Sleep Disturbances.

Insomnia. What is it?

What it is:

Insomnia in Long COVID refers to persistent sleep difficulties experienced by individuals recovering from COVID-19. Long COVID, also known as post-acute sequelae of SARS-CoV-2 infection (PASC), encompasses a range of symptoms that persist beyond the acute phase of the illness. Insomnia, a common feature of this syndrome, involves difficulty falling asleep, staying asleep, or experiencing non-restorative sleep.

Typical Symptoms:

Those grappling with insomnia in Long COVID often report difficulty initiating sleep despite feeling fatigued, frequent awakenings throughout the night, and waking up too early in the morning. Additionally, individuals may experience daytime impairments such as fatigue, irritability, difficulty concentrating, and mood disturbances—all of which can significantly impact quality of life and overall well-being.

Both pain and poor sleep can be symptoms of Long COVID. Studies of healthy people who are woken from sleep every hour or so show lack of sleep, makes them more sensitive to pain¹. Research is underway to see if poor sleep in Long COVID is associated with pain sensitivity and whether sleep deprivation in Long Haulers affects the nervous system’s ability to suppress pain¹.

Who Gets It:

Sleep problems increased significantly for the general population worldwide during the pandemic but insomnia in Long COVID is one of the most common non-neurologic symptoms². It can affect individuals of any age or background who have experienced COVID-19, regardless of the severity of their initial illness³, examples of high-risk factors for developing insomnia are being hospitalised for COVID-19 and being a black person. For the non-hospitalised Long Hauler, risks are being female, age less than 50 years, higher employment and education status⁴. Other factors associated with a higher risk of insomnia in Long COVID are pre-existing diseases such as Diabetes Mellitus, mental health disorders such as anxiety, depression and post-traumatic stress disorder (PTSD)^5,6. Poor mental health is known to contribute to poor sleep.

Possible Causes of Insomnia in Long COVID:

Viral Persistence, Pro-inflammatory cytokines leading to neuronflammation, Autoimmunity, Mitochondrial dysfunction^1,6,7.

Key Points:

Long Covid The Answers

Relief:

Establish a Consistent Sleep Schedule: Maintain regular sleep and wake times, even on weekends, to regulate your body’s internal clock.
Create a Relaxing Bedtime Routine: Engage in calming activities such as reading, meditation, or gentle stretching before bed to signal to your body that it’s time to wind down.
Optimize Your Sleep Environment: Ensure your bedroom is conducive to sleep by keeping it cool, dark, and quiet. Invest in a comfortable mattress and pillows to promote relaxation.
Limit Stimulants and Electronics: Avoid caffeine and electronics, such as smartphones and computers, before bedtime as they can interfere with your ability to fall asleep.
Treat the mental health disorder that accompanies insomnia e.g. depression, anxiety, post traumatic stress disorder. You will likely need professional help for this.
Seek Professional Help: If insomnia persists despite these strategies, consult with a healthcare provider or sleep specialist. Cognitive-behavioral therapy for insomnia (CBT-I) and pharmacological interventions may be recommended to address persistent sleep difficulties.
