For many people with neck pain, back or side sleeping is typically safest. On your back, support the neck gap without elevating the head too much and avoid a chin-to-chest posture. On your side, keep the head and neck aligned with the spine; this requires a pillow that fills the shoulder gap at the correct height. Stomach sleeping often worsens neck pain because it holds the neck in sustained rotation. In addition, arm positioning and a thin pillow between the knees (to support pelvic alignment) can improve comfort. If pain is severe or accompanied by neurological symptoms, professional evaluation is essential.
