I'm constantly stressed, my brain won't switch off. Can this help with that, not just my back?

Yes, and for many people that's even the main reason to come. The hang isn't only about the spine, it's also about the nervous system. When the body realizes there's nowhere to fall and there's nothing it has to control, it switches from alarm mode into deep relaxation, and the mind finally lets go. That's the 'reset without effort': you lie there, breathe, hang - and the accumulated tension dissolves. Many say they leave with a calm head, as if they've exhaled for the first time in a long while.
