What I do, when I finish changing all strings, is tuning all of them 2 to 3 half-steps up.
Say, for instance, F# C# A E B F#
I leave my guitar with that tuning during the night, so when I wake up I detune each string to it's standard afination.
That way I prevent the temporal effect in which each new string (after being inmediately put) starts detuning.
My question is, does leaving the guitar with this tension for 8 hours harm in anyway the strings or guitar?
I use medium and light tension.
I do not know anything specific to guitar strings. But stretching plastic materials causes both plastic deformation (thinner and thicker areas) and microtearing (dislocations that weaken the tensile strength). Both are bad news. I would never stretch a guitar string above its stated operating tension. However, you can check for the amount of damage yourself. If there is plastic deformation, the strings should show variations in tuning at different frets on the same string. You can use an eletronic on-line tuner to check fret by fret (When one note on the string is in tune with the tuner, they should all be in tune.). If there is microtearing, you should be able to see under a microscope that the string is not completely transparent, but shows translucent, milky lines or bruises. If I am wrong and nothing happens, let me know.
