Well I recently started trying out some different less conventional tunings for my guitar, some of these involve tuning every string differently. I have heard that if you do this too often it can damage your guitar, anyone know if there is any truth to this?

Thanks in advance.
it wont damage it unless you tune to like nashville tuning on normal strings.
If you tune down, nothing will happen...
If you tune up too much, your neck may bend (but you would have to tune your strings up like 5 steps or something and they will probably break before that.

This is assuming you don't have a floyd rose or something of the sort
