Sleep Posture Hacks: Head Elevation and Side-Sleeping Effects on Eye Pressure High intraocular pressure (IOP) – the fluid pressure inside the eye – is a key factor in glaucoma and other eye diseases. Notably, IOP can change with sleep position. Studies show that simply lying down tends to raise IOP compared to sitting (pmc.ncbi.nlm.nih.gov).

A wedge pillow is a triangular-shaped cushion designed to raise part of your body while you lie down. It has a sloped surface that supports your head, shoulders, or knees at a gentle angle instead of lying flat. These pillows come in different sizes, heights, and firmness levels and are often made from memory foam, polyfoam, or contoured materials. People use them for sleeping, reading in bed, or recovering after surgery because the incline keeps certain body parts elevated. The elevation can reduce symptoms of acid reflux and heartburn by helping prevent stomach contents from moving up the esophagus while you sleep. It can also improve breathing for people with mild snoring or congestion and ease pressure on the back and neck for more comfortable rest. Choosing the right slope and firmness matters because too steep an angle can cause shoulder or neck strain while too soft may not give enough support. Many wedge pillows come with washable covers and removable pieces to adjust height, and they are relatively inexpensive compared with medical equipment. If you have serious medical conditions, check with a healthcare provider before using one to make sure it suits your needs and posture.
