We take sitting for granted, from our earliest days of living, we sat in a chair. But as time crept on, we forgot about these 'rules of sitting'.
One of the most earliest rules that I learned in my apprenticeship was 'how to sit correctly'. My elbow and body must be in a 'relaxed position' for those long hours.
This tutorial-essay is not a recent discovery on how to sit, but it's a continuation from my earlier learning years, circa 1960's.
==========================================
=> Rules for your body <=
1) Keep your feet firmly planted on the floor and avoid tucking them under your buttocks. That alone will give you a poor sitting position. (I've seen this on many occasions from the younger students).
2) Get off of your chair periodically and get some exercise aka 'move'.
3) Give your eyes a chance to look into a distant focal point. Your eyes need a 'chance to relax' from focusing in a close area. Understand this?
4) Keep your elbow on a thick layer of cloth. If not, your "Ulnar" (sp.) nerves that are running through the elbow will 100% get squeezed and damaged. Arthritis will surely get involved in later years and then subsequently into your joints of your thumb & fingers. (I know this first hand.)
I'm using multiple layers of cloth toweling to facilitate a thick pillow. BTW, the left side of my upper bench is slightly worn away. That is from my shoulder being nestled against it for all of my years of sitting & setting.
This is exactly where my elbow is resting.
5) To avoid such 'damage', exercise your legs by 'standing or walking', loosen up those muscles every 20-30 minutes. This will avoid any 'pooling of the blood' in your legs.
VERY TRUE STORY!
(My family doctor was once was on an airplane for 3 hours had the 'feeling' of a blood clot forming. He asked the stewardess to get him to a hospital as soon as possible, upon landing. YES, he did have a 'blood clot , luckily it didn't travel to his heart).
The name for this major health issue is "Deep Vein Thrombosis" and is caused by long periods of inactivity.
6) Your chair that you are using MUST be well padded and don't sit on a hard chair. I could suggest a 'secretarial chair' as shown here.
"Padding on the chair" is also very important for the 'extra cushioning' for your back and lower extremities.
7) As often as you can, stretch your fingers & get those 'tight finger' muscles moving again.

I truly think that this tutorial essay covers the many important aspects of being able to sit for many hours. Again, please get up & EXERCISE.
