Optimize Your Desk Job Posture
Desk work can really take a toll on your body, especially if you aren't positioned correctly. Here's a list of things to be mindful of:
Top of the screen on your computer monitor should be at eye level.
Computer monitor should be an outstretched arms length away.
Sit close enough to the desk so that your ear is stacked over your shoulder, spine and hip.
Sit all the way back in your chair.
Chair is positioned so that elbows are at a 90° bend.
Feet are flat on the ground.
Keyboard, mouse etc. are close enough that using them doesn't compromise any of the above suggestions.
Shift your body, even slightly, often as you work (roll your shoulders, stretch your neck, wiggle your hips around) to wake up your nervous system.
