I hang by my ankles for a few minutes several times a day. This accomplishes two things:
1. it limbers up my spine, neck, and skull, which allows my body to function more efficiently and more blood to flow through my more relaxed muscles in my neck to my brain, even when I’m not upside down.
2. it helps deliver more blood to my brain, so the more nutrients I have in my blood, combined with increased flow to my brain increases my brain’s ability to heal and make new connections.
My inversion table is a Teeter Hangups, and I find it very hearty and durable.
