Quizplus · Accepted Answer

Using a footrest can help improve posture and reduce back strain by keeping the feet flat on the floor and the knees at a 90-degree angle. Using a lower screen resolution, turning down headphone volume, and using a light touch on the keyboard may help with other issues, but they are not directly related to reducing backache.
