The optimal sleeping position for most people is on the back, with a pillow placed under the head and neck to provide mid‑height, medium‑firm support. A mattress that is firm or moderately firm helps keep the spine aligned naturally, reducing pressure points and helping the body rest without abnormal strain. This view reflects guidance from medical professionals who study sleep health and musculoskeletal well‑being.
There is concern about using a very high pillow. While some may prefer extra height, choosing a pillow that is too tall can alter spine alignment and affect blood flow during sleep. When the head sits higher than the torso, it may place unusual pressure on the neck and vessels, potentially influencing circulation to the brain through the night and waking the sleeper with discomfort.
Excessive neck tension can develop as a result, with symptoms such as morning stiffness, headaches, and, over time, a higher risk of recurring musculoskeletal issues. Opting for a pillow that supports the natural curve of the neck without lifting the head too much can help maintain relaxed muscles and a more restful night.
A very soft or sagging mattress may fail to offer stable support for the spine. When support is uneven, the body can fall into postures that cause discomfort and pain after waking. A mattress that is firm or moderately firm tends to maintain spinal alignment and distribute pressure more evenly, contributing to more comfortable sleep throughout the night.
Past clinical observations note that patients sometimes describe sensations that resemble dizziness or vertigo, which can be linked tosleep posture and neck or head position, rather than to a central health crisis. Ensuring a balanced setup—supported head and neck, and a mattress that holds the spine in a straight line—can help minimize such sensations and promote steady rest.
