Writing code takes a long time to sit, the right posture can reduce or avoid the occurrence of shoulder periarthritis, mouse hand, cervical spondylosis and lumbar muscle strain problems. I just started the first few years of website programming, do not know the correct posture, the above four diseases have occurred, and later study summed up the adjustment of posture, these diseases gradually recovered and no recurrence. A summary of two drawings and descriptions for personal experience, for reference.

1, the eye head-up display from its lower edge upward 66% of the place, the first does not need high tilt or droop, can effectively avoid cervical spondylosis;
2, the keyboard and mouse do not put high or too low, it is recommended to sit in the case with the navel almost the same height, you can avoid the index finger and the middle finger too hard to pull the tendons, effectively avoid shoulder inflammation, mouse hands;
3, if the chair is suitable for height, the waist can be relaxed, can effectively avoid lumbar muscle strain. I sit down a lot of chairs, the price from more than 10 to hundreds of pieces of all have, but the best to sit, suitable for a long time to sit is more than 10 dollars of plastic high stool!
