Sleeping without a pillow could help regulate eye pressure and shape: Research
Sleeping without a pillow may help reduce elevated pressure inside the eye, according to early findings published in the British Journal of Ophthalmology. High intraocular pressure can damage the optic nerve and lead to glaucoma, the leading cause of irreversible blindness worldwide. Researchers suggest that stacking pillows changes the angle of the neck, which may compress the jugular vein and interfere with the normal drainage of aqueous humor. This fluid supports eye structures such as the cornea and lens and helps regulate eye pressure and shape. Intraocular pressure, or IOP, naturally shifts with body position.
