You literally only have seconds to get yourself out of a hanging position even in a full body harness. And yes, every year they find people dead dangling from their harness, belt or other wise. Best way to save your butt is to not only wear a full body harness, but to also have a plan that will get you out the hanging position and back on your stand or safely climbing back down to terra firma.
If used properly, a safety harness won't let you fall lower than your tree stand. so you should never have a reason for just hanging there. You should be able to just climb back up.
