The choice of pillow varies significantly depending on age and the specific physical requirements associated with each stage of life. During childhood, for example, a flat pillow may be needed to provide gentle support to the head as it grows. Moving towards adulthood, some may look for a balance between comfort and posture support. In old age, with increased susceptibility to joint and muscle pain, the choice may lean towards an orthopaedic or ergonomic pillow to ensure optimal support for the spine and neck. Needs change, and choosing the right pillow is essential to ensuring restful sleep and preventing potential health-related problems.
