IS IT RIGHT TO "SIT UP STRAIGHT"?
Many people perceive that "sit up straight" is the proper work posture while you are sitting in front of the workstation. However, this is only partially true. "Sitting up straight", or at 90 degrees can build up fatigue after a short period of time and lead to injuries. The best angle is sitting at 100 degrees, which means slightly recline while sitting in front of a workstation such that the lumbar spine can be relaxed and supported by the chair. Yet, dynamic work postures are always critical in regards to injury prevention.
