To learn proper, strain-free posture while working at a computer, you should try sitting at the screen for a while with exaggeratedly poor posture to experience the effects, a team of American and Dutch researchers suggests.
“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 (5.4 kilogrammes),” says Erik Peper, a professor of holistic health at San Francisco State University, United States, and co-author of the team’s findings in the US-based journal Biofeedback.
