Why your computer can cause neck pain

 Do you tend to suffer from headaches or neck and backaches from computer work? If so, checking your posture may help, researchers say.

Sitting at a computer with jutting head forward to look more closely at the screen compresses the neck and can cause fatigue, headaches, poor concentration, increased muscle tension and can even lead to injury to the vertebrae over time. 

It can even limit the ability to turn the head, the researchers explained.

"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," said Erik Peper, Associate Professor at San Francisco State University. 

"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 added. For the study, published in the journal Biofeedback, the team first asked 87 students to sit upright with their heads properly aligned on their necks and asked them to turn their heads.
