I came across this therapy, called Inclined Bed therapy.
This looks like opposite of Inversion therapy.
All the time we are standing or sitting, our heart has to work hard to pump blood to upper part of the body, and heart gets tired. When we lie down, our heart gets rest, as entire body is at same level. When we invert, it becomes even much easier for the heart, and blood gushes to face, brain, scalp etc.
But with inclined Bed therapy, even while lying down, heart will be working hard.....Why would anyone want to do that???

Old thread but IBT has been gaining popularity from Andrew K Fletcher.
It sounds like they each can address different issues (muscular-skeletal, circulatory) but inversion seems to have way more history. It does seem inclined IBT helped with my varicose veins.
