Many people feel discomfort while using the computer, especially when typing and using a mouse. Here are some tips to help protect your wrists:
Place your keyboard and mouse so that your upper arms hang vertically. Don’t extend your arms too far forwardץ
Your forearms should be parallel to the floor and half supported while typing. If your desk is too narrow and there is no place for support, pressure might evolve at the wrist while working.
Avoid leaning on your wrists. Wrists should “float” over the keyboard while typing.
Keep wrists straight at their neutral position, as one unit with the forearms. Avoid bending them to the sides, upward or downward.
Wrist and keyboard pads can benefit and avoid pressure caused from the desk’s edge. In some cases, they can also add to the pressure: if they are too high, too stiff or when sitting is incorrect. Arrange your working posture and avoid pressing too hard on the pad.
Ergonomic mouses are available in many shapes and styles. Vertical / half vertical mouse can place the wrist in a more neutral way. Give it a try if you feel discomfort.
If you feel that you spread open your arms to the sides while working, consider using a smaller keyboard (that has no numeric pad). This will help get the arms back together to the center.
