Over time, poor posture may be caused by habits from everyday activities such as sitting in office chairs, looking at the computer, driving, standing for long periods of time, or even sleeping. Poor posture can easily become second nature, causing or aggravating episodes of back pain and damaging spinal structures.
Fortunately, the main factors affecting posture and ergonomics are completely within one’s ability to control and are not difficult to change.
The following guidelines suggest several ways to improve posture and ergonomics, especially for people who work sitting in an office chair for most of the day.
Know the warning signs of back pain caused by poor ergonomics and posture. Back pain may be the result of poor ergonomics and posture if the back pain is worse at certain times of the day or week (such as after a long day of sitting in an office chair in front of a computer, but not during the weekends); pain that starts in the neck and moves downwards into the upper back, lower back and extremities; pain that goes away after switching positions while sitting or standing.
