Healthy computing posture

• Keep your back and neck straight.
• Keep your thighs horizontal with a 90 bend at
  the knees.
• Upper arm and forearm should form 90 bend at
  elbow.
• Sit back at least 2 feet from screen.

Good Computing Habits

• Active Breaks.
• Get up from your seat and move around at least
  once an hour. This helps your circulation and
  ensures that you do not stay in the same position
  for too long.
• Eye refocusing.
• Look away from your screen every five minutes or
  so. Let your eyes refocus on something far away.
• Blink Often.
• Blinking lubricates your eyes.
• Clean Screen.
