The 90-90-90 Rule#
When sitting:
- Elbows should be at 90 degrees.
- Hips should be at 90 degrees.
- Knees should be at 90 degrees (feet flat on the floor).
If your feet dangle, get a footrest. Ideally, your keyboard should be at elbow height so your wrists remain neutral.
Monitor Height Matters#
The top of your monitor/screen should be at or slightly below eye level.
- Too low? Tech neck (forward head posture).
- Too high? Dry eyes (you blink less looking up) and neck strain.
Standing Desks: Not a Magic Bullet#
Standing all day is just as bad as sitting all day (hello, varicose veins). The Goal: Movement.
- Sit for 45 mins.
- Stand for 15 mins.
- Walk for 5 mins.
The 20-20-20 Rule for Eyes#
Every 20 minutes, look at something 20 feet away for 20 seconds. Digital eye strain is real, and it kills your focus.
Conclusion#
You only get one spine. Optimizing your setup isn't an expense; it's an investment in your career longevity.
