You spend your days sitting at a desk, strumming on a keyboard eyes on the computer? When the position is not optimal, the body becomes tired and painful. Precisely, specialized advisers, known as “ergonomists”, are there to help us adapt our workstations.
” I have the back of it!” Do you know the expression? “Jokes ergonomist Amandine Simon of the Active Ergonomics consulting firm. She explains: ” the workstation can cause physical pain when it is not adapted, or even stress if the employee is under heavy workload or his social relations at work are degraded “. In France, musculoskeletal disorders (MSDs) are the first recognized occupational disease, with a score of more than 87% according to a 2013 report of the AT / MP account (occupational accident / occupational disease). The purpose of ergonomics? Study the entire professional environment to adapt to the worker. As much from a psycho-social point of view as from a material point of view. For example? Ergonomist Amandine Simon explains how to position herself in front of her workstation, to avoid unnecessary pain.
” The biggest problem in tertiary work is the static posture.The man is not made to stay for hours without moving. ” The goal, then? Make it move from time to time. She recommends doing two types of stops. ” A visual pause every hour is essential.When facing a computer, the near vision constantly contracts the muscles of the eyes.Watching for a minute off allows resting the eye. ” And a physical break: ” every two hours, try to change position, get up and walk, “to work the muscles.
Adjust the height of the workstation
” It is necessary that the environment adapts to the man, and not the opposite “, insists the ergonomist. When you take a bad position at your post, you can feel pain mainly in the neck, trapezius muscles and in the lower back. As a result, you may end up with problems with blood circulation (tingling), or even problems with the venous return.
How to sit? ” You adjust your seat so that you have both feet on the ground and a 90-degree angle to your knees. ” If it’s too low, the angle is closed and the circulation becomes more difficult. The back of the chair should be tilted back slightly to open the angle of the bust and thighs. The ideal height of the office? ” You have to put your elbows in, forming, there too, a 90-degree angle,” says the ergonomist.
On the computer side? ” The top of the screen should be at eye level .” Why ? ” The look naturally tends to go down, so in this way, it is positioned in the center of the screen without effort. ” This avoids over-stressing the neck and creating neck problems.
Place your instruments on your desk
” In all cases, the screen must be exactly in front of you, especially not on one side “, to limit the cervical efforts. The keyboard and the mouse? Place the keyboard ” close to the edge of the desk, away from it by a width of your hand.You keep the mouse close to avoid unnecessary wrist movements “, which can cause pain in the arms. If one wishes to make the entry from paper documents? ” We put them between the keyboard and the screen, ” concludes the specialist.
