When you sit at your desk all day long at work, it’s hard to stay healthy. The Diethack blog covers a few ways to be good to your body while you sit at your desk at work, like reducing repetitive movements: Movements that you repeat over and over (such as answering the phone or reaching for a book) can lead to strains and stress. Reduce unnecessary movements as much as possible by keeping items you use often within arm’s reach and using tools, such as a phone headset, to reduce repetitive movements. You should also alternate the hand you use to operate your computer’s mouse.
