Become a therapeutic riding volunteer: Help horses heal adults with PTSD and kids with disabilities.
Therapeutic riding might sound odd at first, but it's been around for a very long time; it was first used by Romans to rehabilitate their soldiers and in England during the 1960s. Nowadays, therapeutic horsemanship continues to provide numerous physical, emotional and mental rewards -- for everyone from a child with Down Syndrome, to an adult with a spinal cord injury, to a teen with autism.
Once you're trained, there are numerous programs where you can start helping with leading horses, side-walking horses, and assisting instructors: there's Saddle for Soldiers, for instance, where you can help with military personnel who struggle with emotional or physical disabilities, or Saddles and Serenity, which integrates the 12 steps with equine-assisted activities. You'll never find a more rewarding way to volunteer!
