In a chair
Sit up straight. Especially if you're sitting slouched in front of the computer. Just stop playing for a few moments and focus on correcting your posture.
This will cause the blood to renew its flow to your brain as your spine is properly adjusted.
- Sit up straight and deep in the seat. Feet should be flat on the floor or on a footrest;
- Keep lower arms level with the desk and wrists straight. (This helps to prevent carpal tunnel syndrome.);
- Sit close enough to your keyboard to eliminate stretching, but far enough to avoid leaning. Your shoulders should be back and your head should be directly over your shoulders;
- Tap the keyboard lightly; don't pound;
- Place your mouse within easy reach of your dominant hand. Hold the mouse loosely;
- Place the monitor at eye level, 16 to 24 inches away;
- Take short stretch breaks every 20 minutes;
- Exercise eyes frequently. Look away and focus on distant objects; and
- Periodically look up at the ceiling to give your posture muscles a break.
On the floor
- Kneel on the floor with your knees about three fists apart.
- Sit so that your bottom touches, but does not rest on, your heels. (Your thigh muscles have to do a little work here.)
- Place your palms on your thighs, right near your pelvis.
- Sit up straight, so that there is a slight concave curve in your lower back.
- Push your sternum out slightly.
- Tuck your chin in a little.
