Take regular breaks
Many injuries, especially over-use injuries, can be completely avoided in many cases by simply taking regular breaks to stretch, change positions, and relax. Do some deep breathing exercises and take the opportunity to give your body a break from your normal workload, i.e. if you stand all day sit down, or if you sit all day stand up. And if you need to set a timer to go off every hour or so to remind you, do it.
