Aside from using stretches to improve your lower back health, there’s another option that can greatly improve health for office workers: investing in a sit stand workstation.

Many of the health hazards of sitting all day are relieved by the ability vary the position you’re working in. Specifically, it helps significantly improve posture to spend at least part of the day standing.

Last year, Texas A&M found another reason to consider purchasing an adjustable standing desk: they also significantly boost productivity. The study, conducted in a call center in Texas, found that workers who used a sit-stand workstation increased their productivity by 23 percent within the first month and by more than 50 percent six months later.

“We’ve found that there’s been significant growth in standing desk sales,” says Tara Laughter, Marketing Director for Systems Office Furniture in Houston. “The used ones are especially popular because they’re an affordable option.”
