Sitting straight in the chair is indeed bad for the back.
Instead, you should slouch at 135 degrees angle.
Scottish as well as Canadian researchers used fresh magnetic resonance imaging form of which shows that sitting in a straight manner provides needless strain on the back.
BackCare charity’s Levent Caglar says, “Generally, opening the angle between trunk as well as thighs while in a seated posture, is better idea to improve the shape of spine- forming a natural S-shape while in standing posture.”
“When it comes to the best angle when seated between thigh and torso- reclining at an angle of 135 degrees makes sitting more difficult- since one might also slide off the seat. So, an angle of 120 degrees or even less than that could be better.”
The leading University of Alberta Hospital’s Department of Radiology and Diagnostic Imaging, Canada member Dr Waseem Bashir says that’s “Sitting in sound anatomic pose is vital as the tension put on spine’s ligaments and spine can lead to severe pain over a period of time, even forcing towards defects as well as chronic illness.”
British Chiropractic Association’s Rishi Loatey tells that “One out of three people experience lower back pain due to sitting for longer time periods. Also our bodies are certainly not designed to be inactive.”
