The USA-OSHA defined ergonomics succinctly as being the science of designing a job to fit the worker, rather than physically forcing the worker's body to fit the job. If an individuals working environment, processes, and implements used are created with principles of ergonomics in mind, there will be marked reduction in physical stress or fatigue. Ergonomic products and processes will also help eliminate many work-related musculoskeletal disorders or WMSDs that are potentially disabling.
These disorders do not usually happen as a result of a single accident or injury. Rather, these are mostly insidious just like repetitive strain disorders. WSMDs also occur due to awkward posture, and overexertion.
Ergonomic principles apply not only to the workplace but also to residential and other non-commercial settings, like schools. For example, there is growing interest for student desk that are ergonomically designed both to ensure good spinal health and optimize working performance. For a student desk to be considered ergonomic it should not be too high or too low that the one using it has to slump forward. Some desks come with trays so that the hands, wrists, and forearms are kept straight, and in line, and roughly parallel to the floor. Ergonomic bedroom desk for student should also have adequate legroom so your child can frequently change postures and don't have to sit too far away and overreach. Ergonomic bedroom desks for students used as computer desks should have adequate space so that the user will be facing the monitor, keyboard, and mouse. They should not have angled leading edges as these can impede the blood flow and nerve signals to the hands.
An ergonomic desk would not be as efficient without an ergonomic chair. Chairs should allow for proper lumbar support when the person using them is either sitting vertically or leaning back slightly. They should be height-adjustable as well in order for your knees to be at the same level as your hips. The seat pan needs to be depth-adjustable to provide adequate support to taller users while allowing shorter users to sit with their back fully supported as well. The seat pan should provide enough support for most of the thigh without its front edge getting into contact with the back of the user's knee.
These ergonomic desks and chairs are sold in brick and mortar home and office improvement stores and web-based retail shops. Whether you buy it online or offline, it would be good to compare at three to five models so you can get the best ones not only in terms of price but also in quality. Try the product if you can because ultimately your body is the best judge for comfort.
