Leaning forward to type, for example, puts strain on your lumbar region, which can lead to back injuries. When you lean forward, you increase the compression on your vertebrae by up to 200 percent, when compared to sitting in a relaxed, neutral position.
Corrective Tips: Opt for ergonomic chairs that recline. When your seat is slightly reclined, the chair starts to work for your body, resulting in a decrease in postural muscle activity as well as a decline in intervertebral disc pressure in the lumbar spine. If you do not have access to an ergonomic chair, try using a towel. Roll up the towel and put it behind your back, preserving the inward bending of your lower back.
