Ergonomics: definition, need and benefits

In Class 11 Home Science, this topic introduces ergonomics as the study of designing work, tools, furniture and surroundings to suit people’s physical needs and abilities. Students explore why correct posture, suitable work height, proper lighting, safe movement and efficient use of equipment matter in homes and workplaces. The topic explains how ergonomic practices reduce fatigue, strain and the risk of injury while improving comfort, productivity and quality of work. Linked to Work, Livelihood and Career, it helps learners evaluate everyday tasks and suggest practical improvements for healthier, safer working conditions.
