Work can be stressful when you have a lot to do or looming deadlines. This stress can cause tightness in the upper back and neck areas. Stress combined with excessive reaching is a major culprit for repetitive stress injuries. Remember to keep all frequently used items, such as your keyboard and mouse, close to your body, while simultaneously leaning into the back rest of your chair to eliminate tension. Most importantly RELAX! Stand up, take a 5 min break every hour, walk around and get your blood flowing.
