A cervical pillow is a specially designed pillow that supports the natural curve of the neck while sleeping. It helps maintain proper alignment of the head, neck, and spine, which can reduce discomfort and improve sleep quality. These pillows are often made from materials like memory foam or latex, providing both support and comfort. Cervical pillows come in various shapes and sizes to accommodate different sleeping positions, such as back, side, or stomach sleeping. They can be particularly beneficial for individuals with neck pain, cervical spine issues, or those recovering from injuries.
