Ergonomics is the science of fitting workplace conditions and job demands to the capabilities of workers. It is the science of fitting the job to the worker. When the physical requirements of the job and the physical capacity of the worker do not match, then work-related injuries can result. Stress on the musculoskeletal system causes the majority of job injuries. Some of these muscular injuries have been linked to work habits that result in temporary or permanent disability. 

Ergonomics includes: using equipment that will take the strain out of lifting and transferring, organizing work in new ways, such as storing items that are used daily on easy-to-reach shelves rather than near the floor or above the shoulders, and changing how tasks are done. Ergonomics can prevent injuries by helping us understand which tasks and body movements can hurt us and by finding new ways to do these tasks. Keeping your back strong, stretched, and healthy is good.
