The Importance of Water on Training Rides

Most quads don't sweat below their injury so Joe would have to do it manually and douse himself with water. He can't raise his blood pressure because this system isn't efficient enough. It's called autonomic dysreflexia, and it's actually dangerous if you don't recognize the problem and your blood pressure stays too long.
