The soft disks of your spine are the greatest contributor to your natural variation in height throughout the day. As has been stated, hanging from a chin up bar will stretch you out some, and probably moreso than you naturally expand to just by being prone while asleep. Unfortunately, as soon as you get back on solid ground, gravity does its thing and begins to recompress your disks.
Your skeleton, of course, primarily defines your dimensions, and it's a little hard to stretch bones :icon_mi_1 That said though, serious stretching and stressing of ligaments and tendons can, possibly, cause them to grow, strengthen, and hence better support your body weight without sagging or compressing. This would at least slow down the daily shrinking, and cause your average height to increase marginally. I would suspect that this kind of thing would take a fair amount of time and effort to accomplish, with no guarantees. Anything is worth a try, but I don't know how much faith I'd put into it.
Good luck!

Since I'm about 1/3 of an inch too short of height requirements for SNA I did some researching. I read that hanging from a chin up bar every morning and evening plus some serious stretching would make me taller. I'm a little skeptical, can anyone in here verify this? Thanks in advance.
