Ergonomics and human factors are the scientific disciplines focused on designing and arranging environments, products, and systems to fit the capabilities and needs of people. Ergonomic design optimizes well-being, comfort, and performance by reducing physical and mental stress. By considering factors such as posture, movement, and the interaction between humans and their surroundings, ergonomics enhances efficiency, safety, and overall worker wellbeing. It's a key factor in the prevention of workplace injuries and chronic pain.
