Yes, using a standing desk can help burn some extra calories as compared to sitting all day. When standing, your body engages more muscles to maintain balance and posture, and this results in burning more calories. Studies have shown that standing burns about 50 more calories per hour than sitting, which can add up to about 200 calories burned in a typical workday. However, it is important to note that standing all day can also cause fatigue and discomfort, so it is recommended to alternate between sitting and standing throughout the day.
