@Melonlity -- there is at least one good way to reduce tension on your guitar neck. Unless you are playing it, tune it down about a step (in other words, tune the bottom string (the thickest one) from "E" to "D" and back all the other ones off a step, too). That will create less tension and make your guitar neck stay in its intended shape longer.
I picked that tip up after I got a 12-string guitar. If you want to talk about an instrument that is subject to too much string tension, a 12-string is it.
Most acoustic guitars have tuners built in these days and most electric guitar amps have tuners, so it is easy to tune up properly when you pull your guitar out to play it. It's not even that inconvenient to tune your guitar down before you slap it back in the case and can extend the life of the neck. Simple solution, huh?
