The utility model discloses a self-deformation adjusting pillow for health care and cervical spondylosis treatment. A soft venting fabric is wrapped on a skeleton to form the adjusting pillow. The skeleton comprises a bottom plate (1), spring seats (2), a neck collar (3) and adjusting plates (4). At least one row of spring seats (2) are arranged on the bottom plate (1), and the adjusting plates (4) are arranged on the spring seats (2), and the tidily-arranged adjusting plates (4) form a pillow surface. At least one side of the bottom plate (1) is provided with the neck collar (3), and all the components form the skeleton in an integral mode. When a user lies on the back, the height of the pillow is 5-6 centimeters, the pillow is in a dumbbell shape, and the neck collar enables the cervical spine to be 2-3 centimeters higher than the pillow; when the user lies on the side, the pillow is automatically adjusted to the height from the shoulders to the face, and the pillow is changed into a plane shape from the dumbbell shape. Muscles, joints, ligaments and the intervertebral disc are ensured not to be pressed or pulled. The self-deformation adjusting pillow is suitable for people with different heights, weights and physiological curvatures of the cervical spine.
