1. Let your upper arms hang down and put your lower arms straight out when typing or using a computer mouse.
2. Don’t move your wrists up or down as you type, but keep them roughly parallel to the floor. The same holds true for the mouse.
3. Make sure your mouse is positioned so you don’t have to lift your upper arm to use it.
Crunching on a deadline? Don’t forget to break up the day with simple stretches. The Canadian Centre for Occupational Health and Safety recommends the following hand exercises:
- Make a fist. Keep your thumb straight. Slide your fingertips up your palm so the tips are near the base of your fingers.
- With your hand open and facing down, gently bend the wrist from side to side, as far as possible. Hold for three to five seconds. Repeat three times.
- Grasp your hand and hold your fingers with the other hand. Slowly bend your wrist down until you feel a stretch. Hold for three to five seconds. Relax. Repeat three times. Slowly bend your wrist up until you feel the stretch. Hold and relax.
