Ergonomics By: Harrisan

History of Ergonomics The word “Ergonomics” originates form the words “ergon," meaning work, and “nomos” meaning “laws” The Outline of Ergonomics was made in 1857 by Wojciech Jastrzebowski and it was the first time that the term “Ergonomics” was used  At the beginning of the 1900’s was the time when ergonomics was starting to be established into work The rules of ergonomics extended to computer equipment in the 1960’s, followed by the study of computer software in the 70s and later also of the internet and automation (1990), and of adaptive technology in 2000 Terrible Ergonomics

What Is Ergonomics Ergonomics Is… The science of managing equipment at the workplace to optimize the fit between each individuals environment to prevent injury

Ergonomics Isn’t… Doing a task with repetitive or excessive force Long term repetitive force could cause "Cumulative Trauma Disorders" (CTDs) or "Repetitive Strain Injuries" (RSIs) These could lead to more serious conditions such as Carpal tunnel syndrome, Tendonitis, Tenosynovitis, DeQuarvain's Syndrome, Thoracic Outlet Syndrome, and many back injuries, caused by repetitive motion Bad Ergonomics

Benefits Of Having ErgoNomics We Need Good Erogonomics Because… It reduces cost of expanses because bad ergonomics can lead to large spendings on MSD’s (Musculoskeletal Disorders)   Improves productivity, by designing a workplace that allows proper posture and less exertion, this allows the worker to be more efficient Improves quality of life because ergonomics is about safe efficiency and if poor ergonomics are practiced then, as an individual gets older they will develop problems in their joints

Problems From A Bent Back The back is made up of discs which are spongy and cushion the vertebrae in your spine, but discs have poor blood supply. Movement circulates fluid through the discs When you sit still, the fluid is wrung out, so you're depriving discs of nutrition Spending too much time sitting in front of a computer adds stress to the discs, which leads to chronic back tension The chair should have a backrest that fits the curve in your lower back It should be height-adjustable and be able to recline 15 degrees for maximum efficiency If the chair has armrests, they should be at a height where your forearms can rest comfortably with your elbows at a 90 degree angle The chair should be at a height where your feet can rest comfortably flat on the floor or footrest.

Problems From Eye Strain Computer Vision Syndrome is a list of conditions when staring at a computer screen for too long Some of these conditions are Myopia(Near Sighted), Hyperopia(Farsightedness), Presbyopia(Trouble Reading Fine Print), Astigmatism(Out Of Focus At Any Distance) etc. You could use proper lighting to prevent glares or you could purchase an anti glare screen Desktop/Laptop You could also upgrade your display Solution: Back
