Does sitting down help help you regen faster?

I've tried it, and yes, when i sit down my health regen gains an arrow, but, I could be wrong.

Can I get ONE correct answer? Please?

simple test : without any battle or anything, sit and see if you gain a regen arrow

the answer is no

Thank You.

i'm fairly sure that sitting down has no effect on your health regen rate.
you health regen increases (to the max number of pips eventually) over time if you are not takeing damage or attacking... it think this is what you are seeing.
