Keep your keyboard and mouse close
If you’re working on a laptop, always use an external keyboard and mouse to avoid arm, wrist or shoulder pain. Using ergonomic products designed with a human-centered approach can improve posture, increase comfort, lower muscle strain.
To make sure that your neck, shoulders and arms muscles stay relaxed, bring the keyboard and mouse under your fingertips when your elbows are alongside your body. To do so, keep the keyboard close to the front edge of the table.

Lift your laptop
If you can have an external second screen, do so; if not, place your laptop on a few books so that you don’t need to crane your neck.

Take your position
Position your external keyboard with the center of the space bar aligned with the center of your body and the center of your screen. Keep your mouse as close to your keyboard as possible. And position any papers you need between your keyboard and your screen. The key is to not have your head and neck moving left and right throughout the day.
