Lie down on a firm, flat surface, the floor, a yoga mat, or a firm bed, and position the device under your neck so it cradles the base of your skull. Let your head rest back and relax into the stretch, allowing gravity to create the gentle traction at the C1-C2 area. Start with short sessions of 5-10 minutes, especially in your first few uses, and sit up slowly afterward. As your neck adjusts, you can build up to 15 minutes once or twice a day.
