Here’s what you can do to reduce backache from computer use

Washington: Sitting on a computer is something that has become second nature to most of us. However, this seemingly harmless position compresses the neck and can lead to fatigue” headaches, poor concentration, muscle tension and even injury to the vertebrae over time, a new study finds.
In time, prolonged sitting in this posture can even limit the ability to turn one’s head.
The study was published in the journal Biofeedback.
Speaking about why it affects the body in a detrimental manner, San Francisco State University Professor of Holistic Health Erik Peper said, “When your posture is tall and erect, the muscles of your back can easily support the weight of your head and neck — as much as 12 pounds.” He went on to add, “But when your head juts forward at a 45 degree angle, your neck acts like a fulcrum, like a long lever lifting a heavy object. Now the muscle weight of your head and neck is the equivalent of about 45 pounds. It is not surprising people get stiff necks and shoulder and back pain.” Peper, Associate Professor of Health Education Richard Harvey and their colleagues and two research scholars tested the effects of head and neck.
