The consensus among sleep professionals is firm: sleeping on the stomach, known as the prone position, is the unhealthiest available option and should be avoided entirely. This posture necessitates rotating the head sharply to the side for the duration of the night, which torque the cervical spine and spinal cord, resulting in morning neck pain and stiffness that can persist throughout the day. Beyond the neck trauma, stomach sleeping flattens the natural curve of the lower back and hips, placing the entire spine under continuous stress, often leading to chronic aches, discomfort, and potentially contributing to premature facial wrinkling due to constant pressure.
