What is the science of designing the workplace, as well as its equipment and tools, to make specific body movements more comfortable, efficient, and safe?

• A. Ergonomics
• B. Immunity
• C. Minerals
• D. Water

Answer: (A)

Ergonomics is the science of designing the workplace, equipment, and tools to fit how the body moves, so tasks are more comfortable, efficient, and safe. It involves shaping the setup around posture, reach, force, repetition, and fatigue, using adjustable chairs and desks, properly positioned monitors, and input devices that keep the wrists neutral. By considering human measurements and movement patterns, ergonomics aims to minimize awkward positions and excessive strain, which helps prevent injuries and improves performance over time.

For example, keeping your chair at a height that lets your elbows stay roughly at 90 degrees, placing the monitor at eye level, and positioning the keyboard and mouse so the wrists stay straight all contribute to a more comfortable and productive work routine. Tools and handles designed to fit the hand reduce grip effort, and alternating tasks or including short breaks helps avoid repetitive strain.

The other options don’t address how to arrange people and their tools to support movement and safety at work. Immunity relates to the body's defense against illness, minerals are nutrients, and water is a vital fluid; none focus on designing work processes and spaces for better movement.
