People buy standing desks thinking they'll stand all day. Then they either stand all day and get sore feet, back pain, and fatigue — or they give up and just sit at their expensive new furniture.
The research is clear: standing all day is almost as bad as sitting all day. The goal is movement and position changes, not just standing.
The ideal ratio: stand for 15-30 minutes per hour. Start with less and build up. Your body needs time to adapt to standing work.
