Ergonomics is the scientific discipline that focuses on designing products and environments to optimize human well-being and performance. It involves studying how people interact with their workspaces, tools, and equipment in order to reduce discomfort and prevent injuries. By considering factors such as posture, movement, and cognitive abilities, ergonomics aims to create safe, comfortable, and efficient work environments that support the physical and mental health of individuals. This field is applied in a variety of industries, including healthcare, manufacturing, transportation, and office settings, to improve overall productivity and quality of life.
