New research indicates that sleeping without a pillow may help reduce eye pressure in glaucoma patients, prompting experts to evaluate the potential benefits and risks of various sleep postures.
Recent studies have revealed that the choice of sleeping with or without a pillow can significantly impact health, particularly for individuals with glaucoma. This eye condition, characterized by damage to the optic nerve, can lead to vision loss or blindness and is often associated with elevated eye pressure.
According to the Glaucoma Research Foundation, glaucoma can result from several factors, including increased eye pressure, thinning of the optic nerve, and fluid accumulation. A study published in the *British Journal of Ophthalmology* found that glaucoma patients who slept with two pillows experienced higher eye pressure compared to those who slept flat. The research indicated that sleeping in a high-pillow position may reduce blood flow to the eye, potentially due to the neck bending forward and compressing veins.
Dr. William Lu, medical director at Dreem Health, who was not involved in the study, described the findings as “interesting and important.” He emphasized that they highlight how something as simple as sleep posture can influence intraocular pressure in glaucoma patients.
However, Dr. Lu cautioned that this research is still in its early stages and does not imply that pillows are inherently harmful. Instead, he noted that the focus should be on how pillows are used and the degree of elevation. “Balance and personalization” are key, he said, suggesting that while most individuals do not need to eliminate pillows entirely, they should avoid extreme positions, such as sleeping with the head sharply elevated or with the neck bent awkwardly.
For some individuals, particularly those who sleep on their backs, forgoing a pillow can promote a more neutral neck alignment. Dr. Lu explained that this adjustment can reduce strain on the cervical spine, potentially improving comfort and decreasing morning stiffness. Additionally, it may alleviate pressure points caused by overly thick or unsupportive pillows.
However, going pillow-free may not be suitable for everyone. Side sleepers, for instance, typically require a pillow to maintain proper alignment of the head with the spine. Without adequate support, the neck may tilt downward, leading to strain over time. Furthermore, individuals prone to snoring or those with existing neck or shoulder issues might find that sleeping without a pillow exacerbates their discomfort.
For those diagnosed with glaucoma or at higher risk, Dr. Lu recommends consulting a healthcare provider to discuss optimal sleep posture. He suggests aiming for a position that keeps the head and neck aligned without excessive elevation. “Small adjustments in sleep setup can be a simple but meaningful way to support overall health,” he noted.
In a separate interview, Dr. Saema Tahir, a board-certified sleep disorder specialist based in New York City, echoed these findings. She pointed out that prior research supports the notion that “how you elevate your head matters.” Elevating the head of the bed itself can help reduce eye pressure, but using multiple pillows may not have the same effect and could even be counterproductive in some cases.
Dr. Tahir also emphasized that there is “very limited high-quality evidence” demonstrating health benefits from sleeping without a pillow. “What matters most is maintaining proper alignment of the cervical spine, which varies from person to person,” she said. Without adequate support, particularly for side sleepers, the neck may fall out of alignment, leading to neck pain, stiffness, morning headaches, or discomfort in the shoulders and arms.
Ultimately, for many individuals, especially side sleepers, forgoing a pillow may actually diminish sleep quality. Dr. Tahir advises those with glaucoma or at risk to avoid sleeping face-down, which can place pressure on the eyes, and to be cautious with very high or stacked pillows. She also encourages mindfulness regarding side sleeping, as the lower eye may experience increased pressure.
As research continues to evolve, individuals are encouraged to consider their unique sleep needs and consult with healthcare professionals to determine the best sleeping arrangements for their health.
According to Fox News, these insights into sleep posture and eye health underscore the importance of personalized approaches to sleep hygiene.
