Allergic Conjunctivitis Linked to Sleep Disturbances in New Study
A recent online survey reveals a notable connection between symptoms of allergic conjunctivitis and diminished sleep quality, perhaps creating a “self-perpetuating loop” of discomfort and sleeplessness.Teh findings, presented at Academy 2025, highlight the need for eye care professionals to consider systemic health factors when treating patients with allergic conjunctivitis.
“Allergic conjunctivitis is a very prevalent ocular surface disease,” explained a leading researcher. “We see it frequently during allergy seasons and flare-ups. However, within optometry, it hasn’t traditionally been studied in the context of broader systemic health, particularly in relation to sleep.”
To explore this potential association,researchers conducted an online survey between March 17,2025,and May 1,2025,distributing it through both office channels and social media platforms. A total of 466 participants from the United States, Canada, and other countries responded, providing data on hallmark symptoms of allergic conjunctivitis – including itchiness, redness, and eyelid swelling – alongside details about their sleep patterns, quality, duration, and any diagnosed sleep disorders.
The analysis demonstrated statistically significant associations between allergic conjunctivitis symptoms and:
- Sleep quality (P < .001)
- Sleep duration (P = .01)
- Difficulty falling asleep (P = .05)
Notably,the survey data indicated that women experienced poor sleep at double the rate of men,and individuals between the ages of 41 and 60 years were disproportionately affected.
“This research served as a crucial reminder of the importance of integrating systemic health considerations into our practice,” one researcher commented. “It challenges us to move beyond simply treating the symptoms and instead adopt a more holistic approach, recognizing that inflammation may be triggering a cascade of sleep disturbances.”
The study also acknowledged the “chicken or the egg” dilemma inherent in this relationship. “Was poor sleep contributing to the inflammation, or was it the other way around?” a researcher questioned. “Further investigation is needed to unravel this cycle and determine the direction of causality.”

News Report Summary:
Why: Researchers investigated a potential link between allergic conjunctivitis and sleep disturbances, suspecting a cyclical relationship where one condition exacerbates the other.
Who: A team of researchers conducted an online survey involving 466 participants from the United States, Canada, and other countries.The study was led by researchers presenting at Academy 2025.
What: The study found statistically significant associations between allergic conjunctivitis symptoms (itchiness, redness, eyelid swelling) and poorer sleep quality, shorter sleep duration, and difficulty falling asleep. Women and those aged 41-60 were disproportionately affected.
How did it end?: The study concluded that eye care professionals should consider systemic health factors when treating allergic conjunctivitis, moving beyond symptom management to a more holistic approach. Researchers acknowledged the need for further investigation to determine whether poor sleep causes inflammation or vice versa, and to break the cycle.the findings were presented at Academy 2025 in october 2025.
