Sitting for long periods creates stiffness and mental fatigue. Every hour, stand up and move for two minutes. This might be a walk around the room, some stretches, or just standing and moving your body. The movement does not need to be exercise. It just needs to happen.
Set a timer to remind you. When it goes off, stand up. Move for two minutes. Then return to your work. This simple practice prevents the physical and mental fatigue that comes from prolonged sitting.
These movement breaks also refresh your mind. When you return to your work, you think more clearly. Problems that seemed stuck become solvable. Ideas flow more easily.
Set hourly reminders today. When they go off, stand up and move for two minutes. Notice how much better you feel and how much clearer you think when you move regularly throughout the day.
