Sitting up too straight
“Your mom wasn’t totally wrong—hunching can certainly be bad for your back,” says Dr. Neel Anand, MD, the director of spine trauma at Cedars-Sinai Spine Center in Los Angeles, California. However, Anand says the opposite is also true: Sitting up straight for long stretches of time can also cause strain.
“If you work in an office setting, make sure your chair is at a height where your knees are at a 90-degree angle, your feet can rest flat on the floor, and you have proper lower back support,” Anand advises. He also recommends standing up, stretching, and taking a quick walk several times a day.
