So if youâre experiencing back pain, youâre not alone. Many back pain sufferers struggle with whatâs causing their back pain, not realizing the 8 or more hours they spend sitting could be the main culprit. The most common cause of lower back pain is postural stress. For this reason, lower back pain is frequently brought on by sitting too long, prolonged bending, heavy lifting, or even standing or laying down, all for a long time in a poor, rounded back position. According to Cornell University Department of Ergonomics, up to 90% more pressure is put on your back when you sit vs. when you stand.
