When working long hours repetitively at the computer, it's always best to take frequent breaks to reduce eyestrain and injuries. You should also do stretches for the neck, upper body and arms. Exercise the wrists every now and then to avoid carpel tunnel syndrome. Here are some more tips to help reduce your risk of injury.
1. Make sure you have the appropriate chair that's adjustable and a comfortable posture. Both feet should be flat on the floor and your back properly supported.
2. When using the keyboard, your hands should be at the same level as your wrists. You can do this by lowering the height of the keyboard. This technique will help you avoid wrist injuries. An ergonomic keyboard is highly recommended because it's specifically designed to provide more comfort for the user.
3. Place your monitor at or below eye level to avoid eyestrain.
Always remember to apply ergonomics in the home office. By using these tips and taking frequent breaks, you will be able to protect yourself from work related injuries.
