Health is undoubtedly the most important resource for the self-employed. Here are some recommendations for those who use a computer and want to protect their health.
The screen
- Should be at eye level
- Equipped with an anti-reflective accessory
The keyboard
- If the model is traditional, it is wise to use a wrist support to avoid developing metacarpal syndrome, which provokes loss of feeling at the fingertips.
- Arms should be parallel to the floor while typing.
The mouse
- The mouse should always be placed at the same level as the keyboard. If the keyboard is placed in a drawer, a tray can be added for the mouse
- Encourage shoulder and arm movement rather than wrist or else use a wrist support.
- Ideally, you should learn to use both hands to alternate movement.
The chair
- The backrest should follow the curve of your back and offer lower back support.
- The seat should be slightly inclined, long enough to rest your thighs but without touching the back of the knees.
- Too short: forces you to sit at the end of your chair.
- Too long: interferes with blood flow.
- Feet should be flat on the ground.
- If you have raised the seat to type, use a foot support or an old telephone book!
- Stand up at least five to ten minutes every hour.
