The modern workplace demands more from a worker's mind and body than ever before. Understanding the types of ergonomics in the workplace helps recognise how physical comfort, mental clarity, and organisational support work together to protect an employee's health. From the chair that supports the spine through marathon meetings to the workspace design that reduces cognitive strain, ergonomics shapes every moment of a workday. This guide explores how the three dimensions of ergonomics—physical, cognitive, and organisational—create healthier, more productive work environments that support both immediate comfort and long-term wellness.
