Thyroid Eye Disease and Sleep: Understanding the Connection
Explore how thyroid eye disease disrupts sleep quality, why symptoms worsen at night, and evidence-based strategies to rest easier.
Thyroid Eye Disease and Sleep: What You Need to Know
Thyroid eye disease (TED), an autoimmune inflammatory disorder, can complicate life in surprising ways — especially when it disrupts how well you sleep. From eye pain and dryness to anxiety and vision changes, TED brings daily and nightly challenges. Understanding why these symptoms can be worse at night, as well as what you can do about them, is crucial for achieving restful sleep and maintaining your eye health.
What Is Thyroid Eye Disease?
Thyroid eye disease, also known as Graves’ ophthalmopathy or thyroid-associated ophthalmopathy, is a complex autoimmune condition most often associated with Graves’ disease, a form of hyperthyroidism. In TED, the immune system attacks the muscles and tissues around the eyes, causing inflammation, swelling, and other symptoms. Not everyone with Graves’ disease will develop TED, and in rarer cases, TED can occur with normal or even decreased thyroid function.
- Inflammation: Swelling and redness affect the tissues around the eyes.
- Orbital tissue changes: Fat and muscle behind the eyes expand within the bony orbit, pushing the eyeball forward (proptosis).
- Key symptoms: Dryness, grittiness, double vision, eyelid retraction, and, in severe instances, vision loss or eye pain.
How Thyroid Eye Disease Affects Sleep
One of the less-discussed burdens of TED is its impact on sleep quality. Recent studies show that nearly 60% of people with TED experience some form of sleep disturbance. The reasons for this are complex and include physical discomfort, psychological effects, and changes in routine or mood.
Primary Ways TED Can Disrupt Sleep
- Ocular pain and irritation: Corneal exposure and surface dryness create continual discomfort, making it difficult to fall or stay asleep.
- Inability to close eyes: Swelling or changes in eyelids may prevent full closure, leading to significant dryness or corneal ulcers overnight.
- Visual disturbances: Double vision, blurriness, or fear of vision loss can cause sleep anxiety or fragmented sleep cycles.
- Anxiety and depression: Research links TED with elevated rates of anxiety and mood disorders, both of which are known drivers of insomnia.
Why Are Thyroid Eye Disease Symptoms Worse at Night?
Many living with TED report that eye symptoms intensify overnight or first thing in the morning. Several mechanisms contribute to this trend:
- Reduced tear production: Tear secretion naturally drops at night, offering less lubrication for already-irritated eyes, prolonging periods of surface dryness.
- Poor eyelid closure: TED can cause eyelids to retract or swell, making it harder to fully close your eyes, leaving your corneas exposed while you sleep.
- Less blinking: While blinking moisturizes the eyes during the day, it obviously stops at night, exacerbating dryness and irritation.
- Posture effects: Lying down can increase periorbital swelling (fluid shifting into eyelids and tissues), which makes morning puffiness and swelling pronounced.
- Circadian rhythm and inflammation: Natural nighttime increases in some inflammatory markers may worsen swelling or pain.

Understanding the Mechanics: How TED Triggers Nightly Eye Problems
TED’s impact on the orbital tissues is at the root of most night-time discomfort. Structure and function are thrown off in several ways:
| TED Mechanism | Nighttime Effect |
|---|---|
| Eyelid retraction or swelling | Incomplete closure, leading to dry, painful corneas |
| Proptosis (bulging eyes) | More of the eye exposed during the night; higher risk of abrasions or ulcers |
| Surface inflammation | Burning, redness, and discomfort that interrupt sleep |
| Neuropathic pain | Persistent dull or sharp pain, often worse in quiet night settings |
| Elevated intraocular pressure* | Potential for increased discomfort or vision changes overnight |
*Intraocular pressure is known to fluctuate at night, and TED can exacerbate this.
Living with Thyroid Eye Disease: The Daytime and Nighttime Divide
The persistent nature of TED means it can erode both day and night quality of life. Some people notice that their symptoms, especially irritation and tearing, increase as the day progresses, while others find the aftermath of a poor night’s sleep — swollen, painful eyes and blurred vision — most challenging on waking.
- Daytime
- Irritation can be managed by regular application of lubricating drops and frequent blinking.
- Pain and swelling may worsen with prolonged screen use or outdoor exposure.
- Vision changes can impact work, driving, or reading.
- Nighttime
- Symptom control is harder due to lack of conscious blinking or eye closure.
- Dryness, corneal exposure, and burning are common, leading to sleep fragmentation.
Psychological Impact: Anxiety, Mood, and Sleep
Living with TED affects more than just physical health. Many experience significant psychological distress, including anxiety, depression, and mood swings, all of which can independently disturb sleep patterns.
- Appearance changes: The altered facial appearance caused by proptosis and eyelid swelling can damage self-esteem and social relationships, contributing to emotional distress.
- Fear and uncertainty: Concerns about vision loss, pain, and unpredictability add to sleep-disturbing worries.
- Compounded effects: Anxiety and depression perpetuate insomnia, creating a vicious cycle where poor sleep worsens emotional health, which in turn exacerbates TED symptoms.
Who Is Most at Risk for Sleep Problems with Thyroid Eye Disease?
While anyone with TED could struggle with sleep quality, some factors increase the likelihood or severity:
- Duration and severity of TED: More advanced eye involvement (higher proptosis, orbital restriction) is linked with worse sleep.
- Pre-existing anxiety or mood disorders: People with a history of these conditions are more at risk for sleep disruption.
- Visual function impairment: Lower visual functioning scores correlate with poorer sleep overall.
- Older adults: Both TED and sleep disorders are more common as people age.
- Women (especially around menopause): Hormonal changes can exacerbate TED and sleep issues.
How to Improve Sleep with Thyroid Eye Disease
While it may not be possible to eradicate all TED symptoms overnight, there are strategic steps that can dramatically ease eye discomfort and help you get the restorative sleep you need.
Dry Eye Relief Strategies
- Use lubricating eye drops: Artificial tears, gels, or ointments before bed help prevent overnight dryness.
- Apply eye ointments at night: Thicker, longer-lasting formulas form a protective layer on the eye during sleep.
- Moisture goggles or sleep shields: These create a humidified microenvironment, trapping moisture and protecting against air movement that causes dryness.
Physical Adjustments and Sleep Environment
- Elevate the head of your bed: Sleeping with your head raised (6-8 inches) decreases fluid accumulation around your eyes and reduces morning puffiness.
- Use blackout masks with care: Soft, gentle sleep masks can block out light but should not press against the eyelids or increase irritation.
- Regulate bedroom humidity: Running a humidifier counteracts the drying effects of indoor air, especially in heated or air-conditioned rooms.
Medical and Lifestyle Approaches
- Stay consistent with TED treatments: Take prescribed medications (oral or topical steroids, immunomodulatory agents, etc.) and attend all eye doctor visits to stabilize inflammation.
- Treat thyroid dysfunction vigilantly: Keep thyroid hormone levels within the recommended range, as uncontrolled levels can worsen both TED and sleep problems.
- Manage anxiety and depression: Integrate stress reduction strategies — such as meditation, therapy, or, if needed, medication — to break the cycle of insomnia.
Practical Tips for a Better Night’s Sleep
- Follow a routine: Go to bed and wake up at the same time each day.
- Limit screen time before bed: Blue light can disrupt your circadian rhythm and increase eye strain; avoid screens for at least 30 minutes before sleep.
- Gentle eye hygiene before bed: Cleanse eyelids with a mild wipe to remove irritants or makeup, reducing overnight irritation.
When to See a Doctor
It can be difficult to judge when TED-related sleep challenges require professional help. Reach out to a healthcare provider if you experience:
- Severe eye pain that interrupts your sleep
- Vision changes — new blurriness, double vision, or colors appearing dim
- Inability to fully close your eyes, especially if you notice redness or ulceration
- Signs of corneal damage — persistent redness, pain, or lowered vision
- Worsening mood or sleep problems that affect daily life
Frequently Asked Questions About Thyroid Eye Disease and Sleep
Can thyroid eye disease itself cause insomnia?
Yes. Physical discomfort, eye pain, anxiety, and mood changes directly related to TED can all drive difficulty falling or staying asleep. Incomplete eyelid closure and chronic dryness are especially problematic overnight.
What are the best home remedies for eye pain caused by TED at night?
Apply lubricating ointments before bed, use moisture goggles, and ensure your bedroom is not overly dry. Elevating the head of your bed and limiting screen exposure in the evenings can also help.
Will my sleep improve as TED symptoms improve?
Most people notice sleep gets better when eye symptoms are controlled and thyroid levels are balanced. Treating both TED and associated psychological symptoms (anxiety, depression) is key for lasting improvements in sleep quality.
How do I prevent my eyes from drying out while I sleep?
Use ointments, sleep with a humidifier, and consider moisture chamber goggles. For people with severe eyelid closure issues, taping the eyelids shut at night (with medical tape) may be recommended by your doctor.
Are certain people at higher risk of severe sleep disruption with TED?
Those with significant eyelid retraction, visual function impairment, anxiety or depression, and older age are at particular risk. Women around menopause may be especially vulnerable due to hormonal effects.
