Could ditching your pillow improve eye health? New study links sleep posture to glaucoma risk
Sleeping with elevated pillows (e.g., two pillows) may increase intraocular pressure (IOP), worsening glaucoma risk. Lying flat or reducing elevation could help lower eye pressure.
Elevated pillows compress neck veins, reducing blood flow and potentially raising IOP. Proper spinal alignment during sleep is crucial—back sleepers may benefit from a flatter position, while side sleepers still need head support.
No universal rule: Back sleepers may need minimal/no pillow, while side sleepers require support to prevent neck strain. Experts suggest elevating the head of the bed (not stacking pillows) for glaucoma patients.
Poor neck alignment from improper pillow use can lead to chronic pain, headaches and breathing issues (e.g., snoring). Sleep ergonomics also impact conditions like acid reflux and sleep apnea.
Small adjustments (thinner pillow, bed elevation) can improve long-term health. Glaucoma patients should consult a specialist to optimize sleep posture without sacrificing comfort.
