Correct Computer Workstation Position
Sitting at a computer desk all day can take a toll on the body. Repetitive activities and lack of mobility can contribute to aches, pains, and eventual injuries. Sitting at a desk while using the keyboard for hours every day can result in poor circulation to joints and muscles, muscle strain, and it can create an imbalance in strength and flexibility of certain muscles.
You can minimize issues like this by taking short breaks throughout your day and by following these guidelines for your workspace setup to maximize your comfort.
